This credit is fairly straightforward: the existing building selected by your LEED-CI project will either have LEED certification or other green features in place, or it won’t. (If your project hasn’t yet selected a building, consider looking for a building that will perform well under this credit.)
It’s worth considering this credit, because in the best case (Option 1), you can earn five points just for locating in a building certified under another LEED rating system.
If that’s not your situation, you can earn 1–5 points through Option 2 by targeting items on a menu of 12 “paths,” each of which approximates a key LEED credit not otherwise covered under LEED-CI (see the credit language and Checklists tabs for more detail). You can't combine options and earn more than five points.
The number of points you’re likely to earn can be determined early on by reviewing existing building components and characteristics. It’s likely that you can pick up a point or two, even if your base building wasn’t designed as a “green building.”
Keep in mind that this credit is about encouraging tenants to locate in environmentally friendly buildings. The credit is not focused on redesigning the base building to fit the needs of the credit—that would be more likely to fall under another rating system, such as LEED for Existing Buildings: Operations & Maintenance.
Locating in a building certified under another LEED rating system is the most staightforward way to earn the five points for this credit. Photo – YRG SustainabilityHowever, tenants can and should encourage building management to make environmental improvements over time, particularly if a good opportunity presents itself. (For example, if the roof is scheduled to be replaced, the owner could consider installing a reflective roof complying with Option 2, Path 5: Heat Island Effect—Roof.)
Your strategies or green building characteristics need to be in place before submittal of your LEED application.
For the most part, the credit requirements of this credit are consistent with corresponding LEED-NC credits. However, there are some variations, so be sure to understand the requirements of any paths you have chosen to pursue.
The Checklists tab for this credit offers key considerations for each option and path of this credit. For more detail, however, you will be referred to the corresponding LEED-NC credit page within LEEDuser. When reading those LEED-NC pages, be aware of requirements and recommendations that may or may not be relevant to the LEED-CI project.
This credit must be applied to the whole building. The CI space can contribute, but the CI space can’t earn the credit on its own.
No. But, if the schedule allows, you could stall your submittal until the building is certified. Or, if you are in a LEED registered building, the building will likely meet some of the individual paths under Option 2 that can be documented and submitted without having to wait for the whole building’s certification.
No. A project can only earn up to 5 points. Exemplary performance can count for one of the 5 points for Path 4, 5, 10 and 11, or some other strategy, but that goes under Path 12, Other Quantifiable Environmental Performance.
Consider which option is more likely for your project:
Consider meeting as a project team during the pre-lease phase of your project to discuss the best site options for the tenant space, targeting green buildings if possible. Real estate brokers and leasing agents can help you identify buildings that are either LEED-certified, or that have implemented green strategies.
The level of LEED certification attained by the building is not a factor in this credit. Photo – YRG SustainabilityFor either option, this credit largely awards building selection. You can earn points here for tenant improvements (under Option 2), but it’s far easier and more cost-effective to start with a building that already achieves the credit, whether by being LEED-certified or having green features.
Careful building selection is crucial for following this option. Real estate brokers and leasing agents can help you identify buildings that are either LEED certified, or that have implemented green strategies with quantifiable results. The most straightforward wayto earn the maximum number of points, and to document this credit, is to locate your tenant space in a LEED-certified building. Consult the USGBC’s database of LEED-certified buildings while looking at your options. USGBC local chapters may also provide useful information. (See Resources.)
If your project is not locating in a LEED-certified building, guide your real estate broker to include the 12 environmental criteria of Option 2 in the search for your base building. (Refer to the questionnaire available from the Documentation Toolkit.)
If you are attempting any of the paths of Option 2, the environmental features need to be in place at the time of building selection, or at least by the time your CI project submits final LEED documentation.
Rents in LEED-certified or “green” buildings may be higher than conventional rates. However, higher rents are likely to be offset by lower operating costs, as well as higher productivity and return on investment.
To document this credit complete the LEED credit template and upload the final certification scorecard for the base building. Your project building can be certified under any of the LEED rating systems, including LEED for New Construction, LEED for Core and Shell, LEED for Schools, and LEED for Existing Buildings: Operations and Maintenance.
If your base building is in the process of pursuing LEED certification, note that this credit is awarded only if your base building has achieved certification at the time of your submission of the LEED-CI project.
Your safest best in pursuing Option 2 is to look for building environmental features to already be in place at the time of building selection. At the least, they must be in place by the time your LEED-CI project submits its application.
Refer to LEED-NC SSc3 for detailed requirements and documentation tips.
Aim for a building constructed on a brownfield site that was subsequently remediated. Consult with building management to find out if any kind of remediation was ever carried out on the property. Be sure to inquire about asbestos remediation, which also qualifies even though it does not define a site as a “brownfield.”
You may have to check local, state, and federal government (particularly the EPA) offices for lists of buildings in your area on remediated sites.
Obtain documentation confirming that your project building was contaminated and that remediation was completed. Ask building management to provide an ASTM E1903-97, Phase II Environmental Site Assessment and proof of remediation. However, such documentation is not common and may be hard to find if remediation was well in the past. Alternatively, you can provide proof that the building was developed on a brownfield site, as determined by a local, state, or federal government agency via a letter or other formal confirmation.
Refer to LEED-NC SSc6.1 for more detailed requirements and documentation.
Select a building that has implemented stormwater collection and reuse, infiltration, or other quantity-control measures, with rates that meet the LEED requirements.
Request a copy of the stormwater management plan, if there is one, listing the best management practices implemented for onsite treatment or onsite storage of stormwater.
Refer to the stormwater management plan or consult with your building’s civil engineer to learn the site’s imperviousness. If it is less than 50% impervious, the stormwater management plan must equalize the pre- and post-development peak discharge rates and quantities from the one-year, 24-hour, design storm. If your site has more than 50% impervious cover, the plan must reduce the volume of stormwater runoff by 25% from the 1½-year, 24-hour, design storm.
If there is no formal stormwater management plan, work with a civil engineer to identify stormwater management features and confirm the pre- and post-development discharge rates.
If the plan does not meet the requirements, consider working with building management and the civil engineer to revise the plan and add features or performing work to improve infiltration, or install onsite storage and reuse mechanisms. These can be expensive to retroactively install, however.
Refer to LEED-NC SSc6.2 for detailed requirements and documentation.
Try to locate the project in a building that has a stormwater management system meeting LEED requirements. Constructed wetlands, filtering systems, bioswales, retention basins, or other systems that remove suspended solids from stormwater, will contribute to meeting credit requirements. If your project is in an urban environment, the building can install a detention tank that collects rainwater for reuse. Systems must remove at least 80% of the site’s average annual total suspended solids (TSS) and 40% of the site’s total phosphorus (TP).
In order to comply with this path, your building must implement specific best management practices (BMPs). These are found in Chapter 4, Part 2, Urban Runoff, of the EPA Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters, January 1993 (EPA 840B92002). Alternatively, your building should follow the BMPs outlined by your local government if they represent the more stringent option.
If information on the building is not readily available, check with code officials, permitting agencies, and your building’s engineer about the building’s stormwater treatment system and how well it performs.
Refer to NC SSc7.1 for detailed requirements and documentation guidance. Note, however, that the requirement for this option through LEED-CI is to meet the credit requirements for 30% of the non-building-area instead of the 50% required for NC projects.
Find out if your site meets any of the following three options:
To document this credit provide site plans that indicate the areas of shading, highly reflective surfaces, open-grid or pervious-hardscape areas and parking under cover.
Sketchup is a free modeling program from Google that can help you determine the shading area for trees. (See Resources.)
If the SRI of certain surface materials is not known, obtain a small sample and send it to a testing lab. This generally costs a few hundred dollars.
If hardscape has gotten darker over time through weathering, the SRI value of the weathered hardscape must be used. However, some hardscapes can be cleaned to restore their SRI value, or close to it.
You can earn an Exemplary Performance point here under Path 12 by meeting two of the three options described above. (Note that you can earn a maximum of five points under this credit, including Path 12, and that pursuing Exemplary Performance for bonus points under IDc1 is a separate process.)
Tenants benefit from locating in a building that has reduced its heat island effect—through lower operating costs related to cooling the tenant space.
Refer to LEED-NC SSc7.2 for detailed requirements and documentation guidance.
There are three compliance paths available to meet the requirements of this path. Tenants can locate in a building with one of the following attributes.
Ask the building owner for specifications on the kind of roofing materials installed and the SRI values of those materials.
More and more municipalities require that “cool” or white roofs be installed on new buildings, so the stock of buildings that comply with this requirement should increase over time, making this path easier to follow.
Tenants benefit from locating in a building that has reduced its heat island effect, through lower operating costs related to cooling the tenant space.
Refer to LEED-NC SSc8 for detailed requirements and documentation guidance. However, note that LEED-NC covers exterior and interior lighting, while for LEED-CI; you only need to follow the interior lighting requirements.
Even if the LEED-CI project only involves a portion of a building, the requirements here must be met by the whole building.
This is a particularly difficult path to comply with because tenants don’t have control over the entire building, or over other tenants’ design and lighting layouts. This compliance path implies requesting lighting power density from all other tenants and measuring light leakage from the windows. It can be time-consuming to document.
This path is most feasible if your LEED-CI project occupies the majority of the building, and is executing its own lighting design.
Refer to LEED-NC WEc1 for detailed requirements and documentation guidance.
Determine if your building uses 50% less potable water for irrigation than standard water usage by employing a highly efficient landscaping irrigation system or using harvested rainwater or recycled water from the site. To determine this, run a preliminary calculation based on the methodology found in the LEED Reference Guide to determine this.
Find out if your project building’s landscaping includes any permanent irrigation systems, which would be a red flag on your chances of following this path. The presence of native or adapted vegetation, rainwater or graywater collection and reuse would be positive indicators, on the other hand.
If your building’s landscaping makes up 5% or less of the site area, you cannot follow this path.
For zero-lot-line buildings, this path may be difficult to achieve. However, if your building has planters or garden spaces that cover 5% or more of the building site area (including building footprint, hardscape, and parking), your project may still be able to earn a point. Reducing the amount of water used to water a roof garden can also contribute to credit achievement.
If your building uses no potable water for irrigation, it also complies with Option 2, Path 8: Water-Efficient Landscaping—No Potable Water Use or No Irrigation.
Locating in a building that uses less municipal water may result in lower lease rates for the tenants.
You can meet the requirements of this path (along with Path 7) by simply having no irrigation. Alternatively, you can irrigate with non-potable water such as graywater, rainwater, or treated wastewater, but you must still reduce total water used for irrigation by 50%.
Refer to LEED-NC WEc2 for detailed requirements and documentation guidance. Note, however, that while LEED-NC requires 50% of wastewater be treated onsite, this path for LEED-CI requires 100% of water be treated onsite.
There are two ways to comply with this path—choose one of the following:
This path applies to the whole building’s wastewater, not just your (tenant’s) waste water.
Options for decreasing potable water for sewage conveyance include:
Depending on the state and municipality, the use of graywater, as well as the use of waterless fixtures, may be more or less regulated. Check local codes for what is allowed in your area.
If your project team is able to locate in a building that has highly efficient core plumbing fixtures, and the tenant is using these core fixtures in its scope of work, focusing on this credit is highly recommended, as the credit could be achieved with minimal or no adjustments. Compliance here may also contribute to SSc1, Option 2, Path 10: Water Use—30% Reduction, due to the synergy between the two paths, as well as to the prerequisite and credit WEp1 and WEc1: Water Use Reduction.
Locating in a building that has highly efficient plumbing may lead to lower water utility costs for tenants.
If water treatment systems are part of the tenant scope of work, they will need to be commissioned, which may entail additional cost.
Refer to LEED-NC WEc3 for detailed requirements and documentation guidance.
Aim to locate your tenant space in a building that has reduced its water use by 30% (for the entire building) and has instituted a plan to get future occupants to comply.
This path covers the whole building’s water use, not just your tenant fit-out.
This path applies to projects that occupy less than 50% of the total building area. If you occupy most of the building and don’t qualify for this option, consider pursuing WEc1: Water Use Reduction instead.
Calculations are based on the number of occupants that will use the plumbing fixtures and the fixture rates, not on the number of fixtures.
Estimated occupant usage is determined by calculating the number of FTE occupants, as well as transient occupants, for the entire building, not just the tenant space.
If projects can show that the reduction in water use in the building is 40% over the baseline, a point can be earned under SSc1, Path 12: Other Quantifiable Environmental Performance.
Locating in a building that uses water efficiently may lead to lower water utility costs overall, which can translate into lower costs for tenants, too.
Refer to LEED-NC EAc2 for detailed requirements and documentation guidance.
Select a building that has an onsite renewable energy system that can produce at least 2.5% of the building’s (not just the tenant space’s) total electricity or thermal energy needs. These include:
Identify energy sources that make the most sense given your project’s geographical location and climate zone and, if possible, work with the building to install appropriate renewable energy sources onsite—usually photovoltaic panels on the roof. Although this is an upfront cost for the building, it offers potential cost savings over time as well as a visible environmental measure.
If the onsite renewable energy system generates 10% of the annual building energy cost, one point can be earned under SSc1, Option 2, Path 12: Other Quantifiable Environmental Performance.
Locating in a building that has an onsite energy generation capacity may lead to energy cost savings.
This path offers a catch-all way to earn points not otherwise covered by the LEED-CI rating system.
Consider implementing a strategy from another LEED rating system that is not included in the LEED-CI rating system, such as LEED-NC SSc5.2: Maximize Open Space. The LEED Reference Guide contains a list of credits from other LEED rating systems that are pre-approved for use under this path. In most cases, no special conditions apply, but with some of the energy credits from the LEED-EBOM system there are age and scope requirements that must be in place on the CI project to make it eligible.
Follow the exemplary performance criteria of Paths 1–11 offered under SSc1: Site Selection, Option 2 as follows:
See the guidance above and the credit language for specific notes on pursuing these paths.
The LEED-EBOM rating system, which covers operations and maintenance, is a particularly good source for credits that can be applied to your project. LEED-NC may also offer some possibilities, but as it’s focused on design and construction, is less likely. LEED for Schools may offer some opportunities, particularly with its acoustics and mold prevention credits. Work with your base building owner and manager to learn if any of their operational practices would be covered by LEED-EBOM or other LEED rating systems.
The environmental strategies in question must be in place and implemented at the time you submit your LEED application to GBCI.
You may submit an application for a Path 12 point for a feature that is not addressed in other rating systems. It might be helpful to clarify the approach through a CIR (Credit Interpretation Request) unless you know that precedent already exists.
Often building management establishes programs and green building strategies to make the building more attractive to tenants. Common strategies pursued in Path 12 include better outside air, base-building controls, BMS systems or composting practices, or an exceptional transportation management plan.
If your project is in a LEED-certified building, request the LEED scorecard and a copy of the LEED certification. This should be sufficient to document this credit and earn five points under LEED-CI.
Identify a representative from building management who can be contacted for details, documents, and specifications needed to document your chosen paths.
Hold a meeting with the tenant, clients, architects, and base building management to discuss each Option 2 path and potential base-building changes needed to earn those options.
Only five regular points can be awarded for this credit, even if your project is capable of meeting the requirements of more than five of the paths.
If Option 2 paths are not applicable to your building, discuss the possibility of retrofitting and completing renovations to incorporate applicable changes, particularly if the owner already has renovations or maintenance scheduled. Target easy-to-implement points like flushometers, faucet aerators, reflective roof specifications, and irrigation updating strategies.
It is helpful to discuss potential changes early in lease negotiation so that building management has time to decide on and implement needed changes by the time your CI project is complete.
This credit is not about redesigning your base building to fit the needs of the tenants; however, encouraging building management to make improvements benefits both the building and the tenants.
After your initial detective work to identify paths you can pursue, review those paths with operations staff and design team members, checking to see that you are still on course to achieve targeted SSc1, Option 2 paths.
Complete all supporting documents for applicable paths and complete the LEED Online credit form.
If the building has reflective roof or non-roof surfaces contributing to Option 2, Paths 4 and 5, the reflectance of those materials should be maintained over time with proper cleaning. Although maintaining these materials may be out of your scope, consider recommending it to building operations staff.
Make sure that waterless urinals, if installed, are maintained properly, according to manufacturer’s instructions.

A building that prior to its development had more than 50% imperviousness and has implemented a stormwater management plan that reduced predevelopment 1-1/2 year 24-hour rate and quantity discharge by 25% of the annual on-site stormwater load. This mitigation can be achieved through a variety of measures such as perviousness of site, stormwater retention ponds, and harvesting of rainwater for reuse.
Stormwater values are based on actual local rainfall unless the actual exceeds the 10-year annual average local rainfall, in which case the 10-year annual average should be used.
A building that has in place site stormwater treatment systems designed to remove at least 80% of the average annual site area’s total suspended solids (TSSTotal suspended solids (TSS) are particles that are too small or light to be removed from stormwater via gravity settling. Suspended solid concentrations are typically removed via filtration.) and 40% of the average annual site area’s total phosphorus (TPTotal phosphorus (TP) consists of organically bound phosphates, polyphosphates, and orthophosphates in stormwater, the majority of which originates from fertilizer application. Chemical precipitation is the typical removal mechanism for phosphorus.).
These values are based on the average annual loadings from all storms less than or equal to the 2-year, 24-hour storm. The building must implement and maintain best management practices (BMPs) outlined in Chapter 4, Part 2, Urban Runoff, of the EPA Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters, January 1993 (EPA 840-B-92-002) or the local government’s BMP document, whichever is more stringent.

Black paint has a solar reflectance of 0; white paint (titanium dioxide) has a solar reflectance of 1. The standard technique for its determination uses spectrophotometric measurements, with an integrating sphere to determine the reflectance at each wavelength. The average reflectance is then determined by an averaging process, using a standard solar spectrum, as documented by ASTM Standards E903 and E892 index (SRI)1 of at least 29, and/or has open-grid pavement areas that individually or in total equal at least 30% of the site’s nonroof impervious surfacesSurfaces that promote runoff of precipitation volumes instead of infiltration into the subsurface.

From the USGBC website: "The keys to successful green projects have always been preparation, committment and collaboration among all interested parties, and the Green Office Guide: Integrating LEED Into Your Leasing Process is specifically focused on helping tenants and landlords collaborate. This resource will help office tenants integrate green decision-making throughout the leasing process—encompassing team selection, site selection, negotiations, lease language, build-out and the tenant's ongoing operations within the leased space. The information and tools in this guide have been developed to assist tenants and their service providers (brokers, consultants, attorneys, design professionals) in reducing the environmental impact associated with real estate decisions and operations. The information contained within will also be useful for landlords and developers interested in preparing for negotiations with an understanding of the needs of tenants focused on obtaining LEED certification for their build-out."

We are pursuing SSc1 Option 2 Path 10 for a CI project within a CS registered building.
My question is, do I need the Tenant Lease Agreement from the CS project in order to document this credit? The CS base building did not include office fixtures in scope but all the office suites are/will be using fixtures consistent with what the CS scorecard notes. Does LEED require an official document or framework for the credit to be met?
If the fixtures aren't installed I think a Tenant Lease Agreement and/or building-wide LEED requirements that apply to all tenants would be the only way to document a 30% reduction for the whole building. There would have to be some documentation of a binding requirement from the base building with maximum flush and flow rates stated explicitly.
In preliminary design review, we had attempted the Brownfields point, which is an option in SSc1.2.1, as well as 4 other points in that credit. The reviewer responded that we needed to show a remediation program for the whole building, not just the LEED TI project (about 17% of the building). At the time we could not provide that without an extraordinary effort, so we had no response.
The final comment was "Option 2 - Path 1: Brownfield Redevelopment: No additional information has been provided. The documentation does not demonstrate compliance.
One point is denied."
The other 4 points for the credit were awarded.
Now we find that we are unexpectedly close to Platinum, and the owner is creating a remediation program for the entire building, which would have to happen sooner or later (building owner is a government entity).
Were this an independent point we would have just withdrawn after the prelim and tried again in construction review, but with it being buried inside of SSc1, how would we proceed?
Is this even possible?
I'm not sure that you'll have any luck, but I would try to contact your LEED review team by sending an email to LEED Coach and LEED Info and including your project ID number, etc. They may give you a path forward. I would also consider resubmitting the credit via an open ID credit, referring back to SSc1. Technically you are only supposed to get one review of each credit, so not sure that would work ..other than that maybe appeal? Although again once you've accepted a ruling I think that option is closed. I would just contact GBCI and see if they give you any options.
I have a CI project with 20 allocated spaces. The overall carpark / site wide parking is over 200 spaces. The requirement is 3% of the "sites" total capacity per NC SSc4.3 for option 2: Fuelling stations. This will equate 1 fuelling station (assuming the allocated tenant spaces are used) or 6 (if the entire site is considered). Am I correct in understanding the requirement is for the tenants allocated spaces and not the entire site? i.e. Install 1 fuelling station and not 6.
Thanks in advance.
SSc1 is about the building, so if you want to use NC SSc4.3 to document path 12 then you will need to meet the requirements for the entire building - in this case 6 fueling stations.
If you only have 1 fueling station you can meet the requirements of NC SSc4.3 as they apply to your CI project area - 1 fueling station - as an Innovations credit.
We had a CI project returned without approval for SSc1 paths 7 and 8. It is a school project, an addition, and the owner did not install any irrigation systems. There are some rainwater collection and other features related to incidental watering needs, but installed no irrigation system using potable waterPotable water meets or exceeds EPA's drinking water quality standards and is approved for human consumption by the state or local authorities having jurisdiction; it may be supplied from wells or municipal water systems.. We have documented in LEED for homes projects the plant materials installed to validate their drought tolerance, etc. But going by the letter of the credit, path 8 says no irrigation system so as to avoid using potable water is the requirement to meet the credit. Any ideas why this would have been denied? Do we need to demonstrate plant species, or are there some additional documentation that we need to supply. It is a little confusing, because there isn't much guidance other than not providing irrigation...thanks!
Anyone have any ideas on this one? Thx!!
So it's really hard to guess without seeing the specific review comment in this instance. It's also a little confusing how you have rainwater and watering systems for incidental needs but then say you have no permanent irrigation system. Typically, if you have some sort of regular irrigation plan and want Path 8, you need to demonstrate that the non-potable waterPotable water meets or exceeds EPA's drinking water quality standards and is approved for human consumption by the state or local authorities having jurisdiction; it may be supplied from wells or municipal water systems. potential (i.e. what the region expects and your storage capacity) will be enough to cover all your anticipated demand (i.e. you'll always have enough in that storage to be able to water the plants). Perhaps that was the outstanding question in the reviewer's mind?
The other potential question is did you look at all of the existing irrigation on the property? SSc1 looks at the whole building and so you'd need to include everything already installed, not just whether this project added a system. If reviewers saw something that looked like an existing irrigation system, that'd be a reason to push back on the points without additional clarification.
It's really hard to speculate without the actual review language in this case. If you want to post the issues, we could look at it again.
That's helpful, thanks! Yes, we basically documented that there is no installed irrigation system at the whole school, and that the only irrigation that does exist, exists in the form of some rain barrel student projects, etc. The site is covered in drought tolerant grass that is not watered with potable waterPotable water meets or exceeds EPA's drinking water quality standards and is approved for human consumption by the state or local authorities having jurisdiction; it may be supplied from wells or municipal water systems.. This is the first time I've done this credit, so apparently it isn't as simple as just documenting that there is not an irrigation system installed. Yet, there isn't really much in the manual for how to document the point, and the reviewer seems confused.
If the building we have selected has an Energy Star rating of 95, can this be submitted for Path 12: Other Quantifiable Environmental Performance?
Yes. Per the February 2010 Addenda, projects can meet the requirements of LEED-EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating systems. v2009 EAc1 within SSc1 Path 12. You'll want to make sure that you upload a copy of that LEED Credit Form as well as any supporting documentation it requires.
We are submitting for LEED silver (LEED 2009 for CI) for a Tenant Improvment project within an existing building that has an energy star rating of 95. The existing building is not LEED certified. Can we submit for SSc1, path 12 the energy star rating and proof to achieve this credit?
Yes. The base building does not need to actually be LEED certified for the tenant to pursue this credit. You will need to upload a copy of a sample LEED-EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating systems. v2009 EAc1 Credit Form into your project's SSc1 submission, however, to confirm your project's compliance. This is a requirement whenever you use a credit from another rating system. You can get the sample forms within LEED Online (link at top righthand side of page). You'd also want to upload documentation from the base building to validate the most recent official score.
We are planning to get our facility certified under LEED CI (USGBC) Ver. 3.0. The Project where our facility is located is a Building which is registered under LEED India CS and is in the process of getting Pre-certified soon.
My query is: Can we proceed with option 1, under SS CR 1, after the Project is Pre-certified under LEED CS?
Thanks in advance.
You will have to wait until the project is fully certified before you can submit SSc1 Option 1. Precertification is not enough.
Hello - I'm doing a tenant guideline for our C&S project and want to make sure I'm leading the tenants properly in what they can automatically achieve. Since the base building is a LEED Certified project, all tenants seeking certification should get an automatic 5 points under Option 1. Additionally, for Regional Priority under LEED-CI in this zip code, the choices include SSc1 Path 1 and SSc1 Path 2. I assume a tenant could automatically get two RP points by pointing out that the base building achieved SSc3 BrownfieldAbandoned, idled, or under used industrial and commercial facilities/sites who expansion, redevelopment, or reuse is complicated by real or perceived environmental contamination (may include hazardous substances, pollutants, or contaminants). They can be in urban, suburban, or rural areas. EPA's Brownfields initiative helps communities mitigate potential health risks and restore the economic vitality of such areas or properties. (EPA) and SSc6.1 Stormwater Quantity in the C&S certification - right? Do I just give the tenants our final LEED scorecard or LEED templates for those credits so they can prove the base building achieved those credits with their CI Submission? Thanks!
After researching further, I believe we CANNOT do the above as it would be mixing Options 1 & 2. It would be helpful for a confirmation - thanks!
What can be pursued under Path 12? Is there a definite list of measures or credits ?
For v2009 projects - check out ID+C v2009 Reference Guide (version 1) November 2009 Addenda. They added more detail regarding the eligibility requirements. They also included a list of all credits from the LEED-NC and LEED-EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating systems. v2009 rating systems that can be applied/used along with any special conditions in order for them to comply.
I think that text was incorporated into version 2 of the ID+C v2009 Reference Guide as it does not appear on the ID+C Reference Guide (version 2) Addenda document. You can tell whether you have version 1 or version 2 of the Reference Guide by looking at the cover. Version 1 will say "2009 Edition" whereas version 2 will say: "2009 Edition (Updated June 2011)" in the lower left-hand corner.
Thanks a lot Kristina, appreciate it! I only have the older version. Is there a link you could direct me to that lists eligibility requirements?
No problem! You should be able to download it here: http://www.usgbc.org/sites/default/files/DocumentAddendaRG%20ID+C%2010.0...
If that link doesn't work, you can always get the full addenda tables via the USGBC - > Resources -> Addenda page and then filtering by v2009 and ID+C: Commercial Interiors. You just want to always make sure you're looking at the right copy for the right version of your reference guide (the BD+C, ID+C, and O+M v2009 Reference Guides all have multiple versions).
We have a unique situation where we have an owner who wants to install a lot of pv on their project. SSc1 is already filled up with the max 5 points. Is there any way the additional PV can count as on-site renewable far exceeding this particular credit? Can we pursue an ID credit for this? Thanks.
Keelan, you can take credit for the PV under EAc5; On Site Renewable Energy + ID credit for exemplary performanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements..
Thanks, but I am talking about 2009 CI...Ideas?
Keelan, Sorry - EAc5 is available for 2009 CI-Retail. If your project is not retail, you can still submit EAc5 as an ID credit, but that will only be worth 1-point, which is the same as taking Exemplary PerformanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. under SSc1, Path 11. Another idea is that you could also showcase the PV as part of a Green Building Education program, worth another ID credit.
Thank you, this is an office, and that is exactly what I was wondering..1 point potentially for 10% on-site renewable energy production, and another potential point if tied to an education program, both of which we can probably achieve.
This may be a simple question but we need a clear interpretation on this.
How can we apply Light Pollution Reduction Path in our case?
The whole LEED CI Project boundary is within the building's core and approximately 15m from the building perimeter.
Are we getting a point for not having any light spill from our boundary to the exterior of the building? or just simply, this path is not applicable for our project and thus no point at all?
Thank you in advance.
It looks like you're missing a key distinction about SSc1 in LEED-CI when considering this pathway. Note that SSc1 in LEED-CI is the whole-building credit. This means that in order to achieve ANY of the pathways in SSc1, ALL of the spaces within the base building will need to be included in the pathway calculations (both your tenant spaceTenant space is the area within the LEED project boundary. For more information on what can and must be in the LEED project boundary see the Minimum Program Requirements (MPRs) and LEED 2009 MPR Supplemental Guidance. Note: tenant space is the same as project space. and all of the other tenants).
So for Option 2 - Path 6 specifically: it does not matter where your tenant space is in relation to the base building - you need to also be looking at all of spaces/tenants in order to achieve the pathway. As such, you could pursue the pathway in a tenant space on the base building interior. You just need to also consider all of the other spaces and their lighting to make sure that all of those are compliant as well. To be honest, my guess would be that this pathway is one of the most rarely attempted of all of the SSc1 options given that amount of work/effort to obtain the necessary information and documentation from all of the other tenants/base building...
Thanks Kristina. I'll take note of your comment.
I have a situation where the project team members are seeing different versions of the same form. I have reviewed .PDF versions of the forms and verified that everything on the forms is identical, except that one of the forms requires and upload to provide "manufacturer's documentation or calculations to support controller efficiency value in table SSc1-10." . . . they are both version 4 of the form and this is a LEED 2009 CI-Retail project. Has anyone else experienced this situation?
Robin, just to cover one more obvious question—the LEED Online forms are dynamic, in the sense that clicking a button earlier in the form influences what shows up later in the form. Have you checked this possibility?
I don't think I've heard of this situation before.
If attempting Path 9, do the fixtures of the tenant spaceTenant space is the area within the LEED project boundary. For more information on what can and must be in the LEED project boundary see the Minimum Program Requirements (MPRs) and LEED 2009 MPR Supplemental Guidance. Note: tenant space is the same as project space. need to be included as well or do just the ones in the base build need to be included?
If attempting path 9, you need to include all fixtures within the base building (meaning all the common restroom fixtures, all the fixtures in your tenant spaceTenant space is the area within the LEED project boundary. For more information on what can and must be in the LEED project boundary see the Minimum Program Requirements (MPRs) and LEED 2009 MPR Supplemental Guidance. Note: tenant space is the same as project space., all the fixtures within the other tenant's spaces, etc.). Essentially any applicable fixture in the building needs to be included (same thing for all of the occupants - daily average staff of every tenant, daily average visitor/transient of every tenant, etc.).
I just received the Review Report for one of our project. We documented SSc1 option 1 LEED certified Building. This Credit is Regional Priority Available, when completing the documentation I marked the option to Attempt Regional credit. Even though SSc1 was Awarded the RP credit was not. It is not Pending, Denied or Awarded. Not comment just listed with 0 point. I am not sure why this happened. Have you had a similar situation? Do you have any advice on how should I proceed in this case?
Thank you so much for your help.
If this is an older project, I am not sure what is the process but for NCv2009 whenever we obtain a credit that qualifies for RP the icon underneath that column on the scorecard lights up orange and the column under "Attempted" shows 2/1 instead of 1/1 that would normally appear. I would contact the team via the gbci contact page and inquire about this. It might have been a mistake on their part.
We are working on a project in Ireland where the surface water runoff from the site flows directly into a tidal reach (estuary) without attenuation, as this has been confirmed to be the most sustainable approach with the local planning authority. Within BREEAMBuilding Research Establishment Environmental Assessment Method, the first widely used green building rating system, developed in the U.K. in the early 1990s, currently used primarily in the U.K. and in Hong Kong. there is alternative compliance path allowing the peak rate of runoff and volume of run off credits to be achieved by default where sites discharge rainwater directly to a tidal estuary or the sea. Is anyone aware of anything similar with LEED?
Gail, I've never heard of that with LEED. I think you would have to request guidance through contacting GBCI and likely getting a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide or Interpretation for an official ruling. The BREEAMBuilding Research Establishment Environmental Assessment Method, the first widely used green building rating system, developed in the U.K. in the early 1990s, currently used primarily in the U.K. and in Hong Kong. rule is in your favor, but I think LEED would want to see specific definitions of why and when this is the most environmentally friendly option.
I have not read anything where I assume you will likely still have to perform calculations for the volume and rate of stormwater reduction. I would inquire on the GBCI contact page.
You are in what is commonly referred to as a "Direct Discharge" area. Basically, this is usually the most low-lying areas within a major river basin (or an ocean or sea). The thinking is you are not eroding the Atlantic Ocean, and any attempt to infiltrate anything is moot.
If you are discharging to a major reach, such as a river, the thinking is to have all your water gone, before the upstream basin makes its way down to the area of your site. We don't want you discharging from your site 24 hours after a storm when the entire basin runoff is getting there. This is a flood control measure.
I'd look into a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide for this, but part of me feels that your site just is not applicable to this credit, because we would be simply giving you points just because you are in a direct discharge district.
Has anyone successfully submitted the Enhanced Refrigerant Management credit ( LEED NC or CS) for a Base Build as an "Other Quantifiable Environmental Benefit" under LEED CI ? would likely meet the intent of the Path 12 requirements?
Vivien, this seems to me like a good strategy.
Please bear with me, as this question is complicated and takes into account a couple different documents/rating systems. I'm sincerely hoping that I am just missing something obvious, and one of you can simply point that out, and I can stop obsessing about this. This pertains to Heat Island EffectHeat island effect refers to the absorption of heat by hardscapes, such as dark, nonreflective pavement and buildings, and its radiation to surrounding areas. Other sources may include vehicle exhaust, air-conditioners, and street equipment. Reduced airflow because of tall buildings and narrow streets exacerbate the effect. - Roof, Option 3 (BD+C SSc7.2, and ID+C SSc1 Path 5).
On page 119 of the 2009 BD+C Reference Guide, there is an equation listed to calculate the amount of compliant roof areaRoof area is the area of the uppermost surface of the building which covers enclosed Gross Floor Area, as measured when projected onto a flat, horizontal surface (i.e. as seen in Roof Plan view). ‘Roofs’, or portions of roofs, covering unenclosed areas (e.g. roofs over porches and open covered parking structures) are not included in the areas used to evaluate compliance with SSc7.2, though they may be applicable to SSc7.1. for a building with a combination high-albedoAlbedo is synonymous with solar reflectance./vegetated roof. It is listed as follows:
[(Area Roof Meeting Minimum SRI / .75) + (Area of Vegetated Roof / .5)] >= Total Roof Area
On page 6 of the ID+C Reference Guide, there is another equation listed for the same credit, in this case SSc1, Path 5, Option 3. That equation is listed as follows:
Total Roof Area <= [(Area of SRI Roof * 1.33) + (Area of Vegetated Roof * 2)]
This is where it gets confusing. I am currently studying for the ID+C specialty exam, and the answer to practice question #2 for Sustainable Sites on page 60 of the ID+C study guide is calculated incorrectly. The explanation for the question (on page 200 of the study guide) actually USES the first equation above to arrive at the "correct" answer, but it LISTS the second equation above as the equation to use. This is misleading, since 6000 * 1.33 equals 7,980, which means the compliant roof area drops below the required amount by 20 SF, changing the answer to the question (to D, not C, for those following along).
Please note that I am aware of LEED's number rounding principles, but that wouldn't apply in this case, since rounding that number up would actually give the design team an unfair advantage (that is, assuming there is more compliant square footage than actually exists).
I cannot find any LEED Interpretations, Addenda, or other Reference Guide changes to confirm that the equation listed for this credit in BD+C should be used to satisfy ID+C SSc1 Path 5 Option 3 instead of the equation actually listed in the ID+C reference guide for this credit.
Do I assume the ID+C reference guide is wrong, and use the BD+C equation? Am I missing something? I just find it really hard to believe that I'm the first person to notice this.
Thanks for reading,
I understand that this was a complicated (read: terribly framed) question, but in case anyone is keeping track, I did receive a response from the USGBC and there was an error in the study guide. For the test and for project use, should it come up, the second formula listed above should be the one used:
Total Roof AreaRoof area is the area of the uppermost surface of the building which covers enclosed Gross Floor Area, as measured when projected onto a flat, horizontal surface (i.e. as seen in Roof Plan view). ‘Roofs’, or portions of roofs, covering unenclosed areas (e.g. roofs over porches and open covered parking structures) are not included in the areas used to evaluate compliance with SSc7.2, though they may be applicable to SSc7.1. <= [(Area of SRI Roof * 1.33) + (Area of Vegetated Roof * 2)]
Just a general comment on USGBC study materials: I found a LOT of errors throughout the study material when I was looking information over for my exam. For what it's worth, I found that the redline guides on the USGBC website were probably my best resource, I just wish I had found them sooner (but don't anyone worry, I passed with flying colors).
I'm just studying to my AP CI+C exam and also noticed this error in study guide. Actually it is not even an error, but it is frustrating as this 'round-up' in formula (*1.33 vs /.75) is irritating. 75% should always be calculates as SRI area /.75. *1.33 is kind of 'inversion' but to be more exact it should be 1.33333(3), so why to express this formula like this..? The larger the roof areaRoof area is the area of the uppermost surface of the building which covers enclosed Gross Floor Area, as measured when projected onto a flat, horizontal surface (i.e. as seen in Roof Plan view). ‘Roofs’, or portions of roofs, covering unenclosed areas (e.g. roofs over porches and open covered parking structures) are not included in the areas used to evaluate compliance with SSc7.2, though they may be applicable to SSc7.1. SF the difference will be 'growing' and it will always be below required 75%...
I am studying also from CI+C Ref Guide and agree - it has plenty of errors. I just wonder what are these redline guides you're referring to on USGBC website? Thanks,
Sorry for the delay.
With regards to your question on the formula, all I can relay is what was told to me by customer service at GBCI, and what I saw on the test. I agree that the formula can be confusing, but it is what we're supposed to use nonetheless.
As far as the redline guides are concerned, go here: http://www.usgbc.org/resources/list?keys=redline
That is the Resources tab on the USGBC website, with "redline" in the search field. Scroll down to the applicable file and you should be all set. Redline guides are nice because they show what has been changed/added/omitted over time.
We are attempting SSc1 Option 2 Path 10 for a CI project within a CS registered building. My question is that the form provided for this credit automatically populated 30 sec. as a duration for public lavatory faucets. The CS form automatically populates a 15 sec. duration for public lavatory faucets. So, the CS form meets the 30% requirement, but the CI form does not. In addition, in the LEED-CI 2009 Reference Guide, Table 2, the duration for lavatory faucets is listed as 15 sec., not 30 seconds. I can not find any information in errata, interpretations or on this forum that address this discrepancy. Any information would be appreciated.
I recieved the following response from the USGBC:
"The CI form was incorrectly updated to match the CS WEp1 addenda which changed the duration for public lavatory faucets from 15 seconds to 30. Please use the following workaround: after selecting "Public lavatory faucet" as the fixture family, select "Other" from the Fixture Type drop-down. This will allow the Duration to become editable and you may type-in "15." Please use the special circumstances section of your form to explain the issue and the workaround".
Can the project achieve Path4 if there are no parking spaces within the building. The project is a zero lot line as well.
A bit of a a gray area, but I would say not. The idea behind Path 4 isn't to reward not having parking, but to reward preventing the heat island effectHeat island effect refers to the absorption of heat by hardscapes, such as dark, nonreflective pavement and buildings, and its radiation to surrounding areas. Other sources may include vehicle exhaust, air-conditioners, and street equipment. Reduced airflow because of tall buildings and narrow streets exacerbate the effect.. Feels to me more like a cas of non-eligibility rather than automatic compliance. But if you ask GBCI, let us know what you learn.
I understand it's zero lot line, but is there any hardscapeHardscape consists of the inanimate elements of the building landscaping. Examples include pavement, roadways, stone walls, concrete paths and sidewalks, and concrete, brick, and tile patios. at all within your LEED project boundary?
The base building is currently undergoing construction and their LEED certification will not be ready for a couple months. Our tenant fitout portion has already been submitted for Design Preliminary Review but now we would like to submit all of the design credits for Final Review. Since this point along with a few others are not yet complete, can I defer these points by simply not submitting them until the construction review stage? Thank You!
Yes, I would simply defer this credit.
We have a client who is leasing two entire, adjacent buildings for 12 years. They are taking on installing high SRI roof membranes and a photovoltaic canopy system in the parking lot. It seems logical that they should be able to use these for SSc1.2.5 & 1.2.11, but the wording of the credits only covers the owner having put these improvements in place previously.
Can we utilize these improvements for points? Would we need to defer SSc1 until construction submittal, so they are already in place?
Yes, I would defer until the improvements are in place. The credit is meant to reward site selection, not site improvements, so any improvements should be in place to be recognized.
The building chosen for this LEED CI project already has a BREEAMBuilding Research Establishment Environmental Assessment Method, the first widely used green building rating system, developed in the U.K. in the early 1990s, currently used primarily in the U.K. and in Hong Kong. rating - BREEAM is the UK's version of LEED. Has anyone got any experience of whether this could count towards either Option 1 - selecting a LEED certified building or Option 2 - Path 12 Other Quantifiable Environmental Performance. Any suggestions welcome!
I don't think that Option 1 will work but you should be able to make a strong case for Path 12. I don't have any experience with this but with a strong narrative (think BREEAMBuilding Research Establishment Environmental Assessment Method, the first widely used green building rating system, developed in the U.K. in the early 1990s, currently used primarily in the U.K. and in Hong Kong. case study of building) I expect it would be accepted.
I submitted (about 3 months ago) a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide on option 1 BREEAMBuilding Research Establishment Environmental Assessment Method, the first widely used green building rating system, developed in the U.K. in the early 1990s, currently used primarily in the U.K. and in Hong Kong. in lieu of the LEED building and it was refused. I've not tried option 2 path 12 but could be worth submitting
Looks like option 2 path 12 is the one to go for. Thanks for the advice!
Has this worked out? It was rejected on our project.
The base building is currently pursuing LEED certification at the same time we are doing the tenant fit-out portion and pursuing LEED CI. Can we get these 5 points through Option 1 somehow?
Nick, the most obvious way to do this is to time your final LEED application such that the building's application has been processed. This could be as simple as staggering your application by a few weeks behind theirs. If being submitted at the same time, you could include a narrative about how the reviewer should reference the pending certification when reviewing this credit.
We are doing a renovation on a hospital in Las Vegas NV. The hospital has two very small patches of landscape that use what we believe to be an efficient irrigation system. To fill out the form on LEEDonline.com, we need to fill in an 'irrigation baseline case' and an 'irrigation design case'. I've been told to fill out what exists at the hospital for the design case, and what "conventional practice" for the area is in the baseline case. How do I figure out what the exact numbers would be for 'conventional practice'?
Brian, what you have been told is correct, and your question about what exact numbers should be is also a common issue. A good place to read more and get a better sense of this is on our NC WEc1 guidance and forum. In short, there is no one-size-fits-all method, so it's helpful if you read a bit more and get a sense of how to go about it.
We have a project that is moving into a building that has been certified under LEED for Homes Mid-Rise. Can the project still pursue option 1?
Ryan, as the credit language says "LEED certified building" without specifying a rating system, I would think this would be fine.
In one of my project, they are attempting this point. While we have the water fixtures details & occupancy of the project space(tenant) only. Online template asks us to get the information of the water fixture details & their flow rate for the whole building which is not possible to get it. So how do we proceed ahead with this point?
Sourabh, you will need the information for the whole building. While all the other credits in LEED-CI are just about the tenant spaceTenant space is the area within the LEED project boundary. For more information on what can and must be in the LEED project boundary see the Minimum Program Requirements (MPRs) and LEED 2009 MPR Supplemental Guidance. Note: tenant space is the same as project space., the point of this credit is to reward and recognize whole-building performance. If you can't get that information, then you won't be able to attempt this path, unfortunately.
Our project space occupies a majority of the building, however the only other tenant spaceTenant space is the area within the LEED project boundary. For more information on what can and must be in the LEED project boundary see the Minimum Program Requirements (MPRs) and LEED 2009 MPR Supplemental Guidance. Note: tenant space is the same as project space. is unoccupied. Is Path 7 - Light Pollution Reduction possible? The landlord may be amenable to including LEED credit requirements in the lease for the unoccupied tenant space. Would this satisfy the credit requirements if a copy of the lease was provided? I'm assuming this approach wouldn't work for Path 10 - Water Use Reduction as there is no way to know the future occupancy profiles of the space.
Yes, I'd say you could meet this requirement with a lease. For water use reduction, I'd suggest looking at CS Appendix 4 in the BD&C LEED Reference Guide, if you have access to that.
Is it possible to achieve only the points for path 8, without achieving path 7? Under path 8, the wording states that the 2 points are in addition to path 7. So is path 7 a pre-requisite for 8? Do you automatically get the two points for 7 if you qualify for 8? Thanks.
