Easier for dense urban sites
This credit addresses two basic issues: density of the surrounding neighborhood and occupant access to everyday services. It encourages use of existing infrastructure and tries to reduce environmental impacts of transportation. It’s easier for projects located in a densely built area or with a host of community services nearby.
This credit, like SSc1: Site Selection, is intended to encourage commercial interiors projects to locate in more environmentally friendly buildings. Many projects have a location determined by other factors, so while it may not be a strong driver for that decision, it does reward you for locating in developed areas and for choosing infill instead of greenfield sites.
than Option 1. | Image Courtesy YRG Sustainability" width="407" height="298" class="image-right" />In determining how easily your project can comply, site selection is one key factor, but so is the availability of property and building data for documentation purposes. Two compliance options
There are two compliance options for this credit. Unless you are in a dense urban neighborhood where either option is possible, your choice will probably be determined by the specifics of your project.
- Option 1: Development Density requires the density of the community to be 60,000 square feet of floor area per acre or more. This is a typical density for a two-story downtown development.
- Option 2: Community Connectivity requires connections to neighborhood services as well as to housing with at least 10 units per acre. This option could apply to a variety of settings, from urban areas to rural small towns with density of services.
Documentation is key
Project teams should assess early in the planning stage which path is most suitable based on project location and the availability of density data. The owner, architect or civil engineer (if your project team has one) often take on the role of documenting this credit—either researching community services in the project’s vicinity, or documenting the density of the project and surrounding area.
The size of the area that has to be included in the Option 1 calculation depends on the size of your project site.
Eight of the ten services for Option 2 have to be existing and in operation at the time of the project opening. Two services can be anticipated within a year of opening. One service can be within the project itself.

FAQs for SSc2
What exactly does LEED mean by residential neighborhood or area?
LEED defines residential neighborhood or area as a minimum of 10 living units (i.e. an apartment unit or house) per acre. Apartment buildings, neighborhoods, or dormitories can all contribute to this.
Only a portion of my complying residential development lies within the ½-mile radius. Will this suffice for credit compliance?
It can be easier to earn this credit in a dense urban environment, but an average two story downtown can also comply. Photo – YRG SustainabilityIn LEEDuser's experience, if a residential development of 10 units/acre lies within a portion of the ½-mile radius, it likely will contribute to credit compliance. This is consistent with LEED Reference Guide guidance that states, "Mark all residential developments within the radius. For the project to earn this credit, a residential area with a minimum density of 10 units per acre must be present within the radius."
Where do I draw the radius from?
Use the center of the LEED project boundary.
Is one building or residential area enough to satisfy the residential density requirement?
Yes, LEED user’s experts have had success with documenting a single property that is at least 10 units/net acre density. Any discrete area that addresses the requirements is acceptable, and an existing residential area meeting the requirements may cross property lines between different properties. For projects with residential areas that are on the cusp (or perceived as being on the cusp) of meeting the required density, you may need to provide additional documentation or an explanation as to how the residential area meets at least 10 units/net acre. Finally, it is not sufficient for the area to be zoned to the correct density, if it is not built to it.
My project has access to services that seem to be basic, but are not listed in the LEED Reference Guide—like insurance company, nail salon, auto repair shop. Will these count?
Probably not. Project teams need to be careful when trying to pass off services not explicitly given in the LEED credit language. In most cases services not listed will not be approved. Review the credit intent and think about whether the additional services—in the absence of other basic services—are pedestrian-oriented and encourage walkable neighborhoods. However, some projects have had success in specific cases, such as a hotel being considered as a basic service for an office space with frequent contractors visiting. 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 is probably needed to get approval for special cases like this.
Also, to reduce confusion during a review while maintaining honesty, be careful to label your services to be consistent with the credit language list. For example, a "nail/hair salon/barber shop" should be categorized as a "beauty salon." If a gas station contains a full-service, stand-alone convenience grocery store (e.g. 7-Eleven) and credit is sought for grocery store use, label it as "convenience grocery" rather than a "gas station."
My project is on a base or campus where some services are available to the population of the project, but not the general public. Do these count?
Maybe. Language in the Reference Guide is not crystal clear on this point, and some comments from project teams indicate that campus projects should demonstrate that services are open to the public. For LEED documentation purposes, LEEDuser recommends avoiding relying on such services, or seeing a CIR to be sure of your approach.
LEEDuser has seen reports of review comments questioning the inclusion of services on a military base or other installation that are not open to the general public, even if they are open to anyone within the radius. On the other hand, one project team reported success with a military base where access to the base was restricted to the public, and services on the base were open to anyone on the base.
For Option 2, does the residential neighborhood with average density of 10 units per net acre have to be existing, or can planned neighborhoods count towards earning this option?
The SSc2 Option 2 residential requirements for NCv2.2 and NC 2009 are for projects to locate in an area within one-half mile of an existing, not planned, residential district featuring a density of at least 10 units/acre. Projects should not depend upon planned residential areas for credit compliance, as this does not represent existing infrastructure in most cases. Projects not meeting these requirements but believing they meet the credit intent will be considered on a case-by-case basis and must submit a project-specific CIR to determine their compliance potential.
What site area should be used for an interiors project when figuring out the density radius? The building site area, or building footprint?
All projects use the building site area for the density radius calculation.
Is my site previously developed?
Many projects have had questions about the definition of previously developed. Note that LEED 2009 projects have had the relevant definition updated by USGBC through a November 2011 addendum. Be sure to reference that definition, which is more specific, if it is applicable to your project.

Determine early on which of the two compliance paths is most feasible for your project. This will be determined by your project location. For projects that have the choice, Option 2 may be easier to document, although both options require developing a site plan and documenting the existing conditions of the surrounding area.
- Option 1: Development Density is for project sites with a density of more than 60,000 square feet of built floor area per acre of land.
- Option 2: Community Connectivity is for projects within a half-mile of a residential zone with an average density of 10 units per acre.
It can be easier to earn this credit in a dense urban environment, but an average two-story downtown can also comply. Photo – YRG SustainabilityTypically, the requisite neighborhood density for Option 1 of 60,000 ft2 per acre can be met by two-story downtown development, or a denser area. The requirements for Option 2 can typically be met in a variety of settings, from dense urban areas to rural small towns with some density of services.
You can earn an Exemplary Performance point through this credit, but only through Option 1: Development Density. If you have some choice of which option to pursue, and the extra point is important, go for Option 1.
Weigh the pros and cons of locating a project in a dense urban area, as there may be trade-offs involved. For example, air quality and open space are two variables that could be compromised by locating a project in a dense urban area. However, LEED is generally oriented toward rewarding projects that locate in urban areas, particularly through SSc4.1 and other SS credits.
Careful site selection is crucial for obtaining this credit. Projects located in dense urban areas will qualify more easily, whereas projects located in rural or suburban areas, where densities are lower and development more spread out, may find this credit unattainable.
Option 1: Development Density
Calculate the average neighborhood “built” density, with a target of 60,000 ft2 per acre, minimum, including your project building as well as surrounding buildings. Undeveloped public areas—including parks, water bodies, and public roadways—are not included in density calculations.
All occupied buildings must be counted in the development density calculations. This would generally include conditioned spaces intended for occupancy, with an FTE above zero. Typical excluded spaces might be:
- parking garages;
- smoking pavilions;
- and maintenance sheds not intended as workspaces.
This approach is much easier to document if density information is accessible via a database of the built densities of all buildings in a neighborhood. Without such a resource, it can be hard to locate this information, and Option 2 may be preferable from a documentation standpoint. Obtaining this data can be a challenge if municipalities don’t provide a centralized database of building and property information for existing building stock—including lot area, building area, and number of residential units. Check with your local planning department or the regional, county, or state planning office GIS database.
Locating your project next to a water body or park shouldn’t affect your density calculations, as undeveloped public areas, including parks and water bodies, are not factored into density calculations.
If moving into an existing building, it may contain asbestos or other contaminants that need to be remediated. Investigate and address any contamination and remediation issues early in the planning process. Doing so can contribute to earning SSc1, Option 2, Path 1.
There may be a fee associated with obtaining data from a public agency’s GIS database.
Option 2: Community Connectivity
Demonstrate that there is both:
- Pedestrian access to common services. Examples of basic services include: bank, church, school, grocery, laundry facilities, doctor’s office, and a post office. (See the list of common acceptable basic services in the credit language.)
- Proximity to a residential area within a one-half mile radius. The residential area must have an average density of 10 units per acre.
If a service is considered basic but not included in the list, attach a narrative explaining why you think this is acceptable or consult with GBCI.
The one-half mile radius is drawn from the main building entrance.
Documenting this option is easier than documenting Option 1, as there is little data collection involved, and usually no calculations to perform (unless there is no other documentation available and you have to calculate the housing density to make sure it is at least 10 units per acre).
Locating within an existing urban fabric adds significant benefits for users, including lower transportation costs and healthier lifestyle. Employers may find that this helps attract and retain personnel.
To check your project’s eligibility to pursue this option, draw a circle with a one-half-mile radius centered on your project’s main entrance. If there is a qualifying residential development, and at least ten basic services, within the circle, your project is eligible to pursue this path.
There must be pedestrian access to the basic services. Pedestrians cannot be blocked by walls, highways or other permanent barriers.
To find the density of residential buildings near your project, check with sources like planning departments, or property management companies on a building by building basis.
For mixed-use projects, one service located within the project boundary may be counted towards the credit calculation, and that service must be accessible to the general public. For example, if your project is an office complex with a coffee shop and dry cleaners—and they are accessible to the general public—one of these two can count as one of the ten required basic services.
At least eight of the ten required services must be operational at the time of project completion. For services that are nonexistent but proposed (up to two of the ten required services), the project team must demonstrate that they will be up and running within one year of occupancy. This can be documented by signed lease agreements or a letter from the developer or owner stating the scheduled opening of the service
Access to services can improve occupant satisfaction with any programming type—resulting in better productivity.
Schematic Design
Expand All
Complete density or community connectivity calculations relevant to Options 1 or 2 below.
These tasks could be completed in schematic design, design development or at 100% CDs. What is critical is to have the project square footage and site area set prior to performing final calculations.
Option 1: Development Density
Your project area must be defined consistently throughout all LEED credits (per the project description).
Check that your project can comply, using these three steps:
- Divide the total project square footage by the total site area in acres. (The minimum density required by this credit is 60,000 ft2 per acre).
- Convert the total site area in acres to square feet (acres X 43,560 square feet) and find the square root of this number. Then multiply the result by 3 to determine the appropriate density radius in feet. Density Radius = 3 x √ [site area in acres x 43,560 ft2/acre].
- Define a circle based on the density radius to serve as the density boundary. Add the square footage of all buildings within the boundary and divide by the total area of all sites in the density boundary in acres. Include both the entire floor area and entire site area for all properties within and intersected by the density boundary (i.e., where the radius boundary intersects a building, even if only partially). Be sure to include your project site as well. Parks and water bodies can be excluded from the density boundary area.
The calculator within LEED Online computes the density radius as well as the average density by summing up the building square footages and the site areas in acres.
Confirm that the average density of your project is at least 60,000 ft2 per acre.
Per CIR 9/22/06, you can document Exemplary Performance as part of IDc1 through Option 1: Development Density using one of the following methods:
- Document that your project has twice the density of the average surrounding neighborhood within the established density boundary area.
- Demonstrate that the average density in an area twice as large as the density boundary is at least 120,000 ft2 per acre. Establish the expanded density boundary by doubling the size of your site area and redoing the square root calculation.
Option 2: Community Connectivity
Use online mapping resources such as Google Earth to draw a one-half mile radius from the project building entrance. Your project must be within one-half mile of a residential development with a density of at least ten units per acre, net, as well as within one-half mile of ten basic services.
For projects with more than one main entrance, you may draw a circle from more than one entrance. The area contained within the circles drawn from all these radii is then used as your project’s radius.
Identify at least one residential development that meets the requirement within the defined boundary. (This could be one apartment building containing ten units.)
If you determine that your project is eligible for this credit option, develop a list of all the services within that half-mile radius (or several half-mile radii), and their distance from the project site.
All the services must be accessible by foot via an uninterrupted, safe path stretching from the designated entrance to the service location. The path cannot cross a highway, for example, unless there is a pedestrian pathway.
For onsite services or those within a half-mile, you can count up to two restaurants in the list of ten community services, but no other service can be counted twice. For example, if there are three restaurants, two hair salons, and four dry cleaners within your radius, you can count two restaurants, one salon and one dry cleaner.
If any of the ten services are nonexistent but planned, you must obtain written documentation that these services will be operational by the time the occupants move into your building. Appropriate documentation includes a lease agreement or a letter from the owner or other responsible party. Only two unbuilt but planned services can be counted in your credit documentation.
Websites like Walkscore and Google Maps can provide locations of services and walking access from a given address. (See Resources.) Note, however, that resources like these contain limitations that may not match up with LEED requirements (Walkscore, for example, assumes that you can walk across water, if that's the most direct route.) Use them as a starting point to identify services and approximate distances, but be sure to make adjustments as needed.
Design Development
Expand All
Check that no changes are made to the design that might hurt your chances of earning the credit.
If your project site is located in a dense urban area where pollution is a concern, design your building to minimize potential air quality problems. Place outdoor air intakes away from sources of pollution as much as possible. Consider acoustics and other issues that might be associated with urban environments.
Construction Documents
Expand All
Complete the LEED Online credit form and prepare the following documents to show credit compliance, according to your chosen option. The LEED Reference Guide also offers good process guidance and sample documentation for this credit.
For both options, a licensed professional (PE, RA, or RLA) can sign off on the credit in lieu of entering all the calculations. The professional whose license is on the line will likely want to confirm all the calculations anyway, and the credit form offers a good way to do that.
Option 1: Development Density
Provide a site-vicinity map, to scale, showing the project site and the one-half mile boundary from the project’s main entrance. Highlight the residential development and ten services within the boundary.
Compile a list of all buildings that are within or are intersected by your density boundary, with square footages and site areas for each property. Highlight the results of your calculations and confirm that your project meets the credit requirement.
Option 2: Community Connectivity
Provide a site-vicinity map, to scale, showing the project site and the one-half mile boundary from the project’s main entrance. Highlight the residential development and ten services within the boundary.
Demonstrate through an online tool, picture, or site plan that ten services are accessible by foot from the project site.
Compile a list of services for easy review, and confirm that the credit requirement is met.

6 Points
Intent
To channel development to urban areas with existing infrastructure, protect greenfields and preserve habitat and natural resources.
Requirements
Option 1: Development density
Select space in a building that is located in an established, walkable community with a minimum density of 60,000 square feet per acre net (13,800 square meters per hectare net). The density calculation is based on a typical two-story downtown development and must include the area of the project being built.
OR
Option 2: Community connectivity
Select space in a building on a site that meets the following criteria:
- Is located within 1/2-mile (800 meters) of a residential area or neighborhood with an average density of 10 units per acre net.
- Is within 1/2-mile (800 meters) of at least 10 basic services.
- Has pedestrian access between the building and the services.
For mixed-use projects, no more than 1 service within the project boundary may be counted as 1 of the 10 basic services, provided it is open to the public. No more than 2 of the 10 services required may be anticipated (i.e., at least 8 must be existing and operational). In addition, the anticipated services must be documented appropriately to demonstrate that they will be operational in the locations indicated within 1 year of occupation of the applicant’s project. Examples of basic services include the following:
- Bank
- Place of Worship
- Convenience Grocery
- Day Care Center
- Cleaners
- Fire Station
- Beauty Salon
- Hardware
- Laundry
- Library
- Medical or Dental Office
- Senior Care Facility
- Park
- Pharmacy
- Post Office
- Restaurant
- School
- Supermarket
- Theater
- Community Center
- Fitness Center
- Museum
Proximity is determined by drawing a 1/2-mile (800 meter) radius around a main building entrance on a site map and counting the services within that radius.
Greenfield developments and projects that do not use existing infrastructure are not eligible.
Potential Technologies & Strategies
During the site selection process, give preference to urban sites with pedestrian access to a variety of services.
Web Tools
Google Maps
For locating community services on a map in relation to project site.

Google Earth
Great resource for creating site maps and measuring distances.
Walk score
This online tools provides “as-the-crow-flies” distance to typical standard services from a given address, so it is most helpful to identify the location of basic services that are in close proximity, but shouldn’t be used to document walking distances.

Basic service in community connectivity
i have a commercial interior building that lies in an office park with a lot of landscaped areas , can this be considered as the park as one of the 10 basic services surrounding the building ?
also beside the building, there is a natural reserve , can it be considered as a park ?
Soha, I don't think an open vegetated area would be accurately described as a park, for this purpose.
definition of greenfield for commercial interiors
Hi all,
how can a fit-out that is to be certiifed by commercial interiors be a "greenfield development" ?
Surely once the core and shell project is completed, the fit-out is on a previously developedPreviously developed sites are those altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Previously developed land includes a platted lot on which a building was constructed if the lot is no more than 1 acre; previous development on lots larger than 1 acre is defined as the development footprint and land alterations associated with the footprint. Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development." site. This should be true even if it is the first fit-out in a new building that was built on a greenfiled site
HI Ken,
The CI reference guide specifically states that "greenfield developments and projects that do not use existing infrastructure are not eligable." I agree with your assumption that a TI space moving into a building, even a new one, is moving into a "previously developedPreviously developed sites are those altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Previously developed land includes a platted lot on which a building was constructed if the lot is no more than 1 acre; previous development on lots larger than 1 acre is defined as the development footprint and land alterations associated with the footprint. Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development."" condition.
Option 1 - is a residential element required?
If a project is pursuing option 1 development density calculations must there be a residential element recorded within the 60,000sf/acre figure?
thank you
Vivien, a residential component is not required for Option 1.
Option 2 - Future residential development
Our project is located in a new area in which a residential area will be developed in the near future but is not developed yet. Is it possible to count this area for option 2?
Thanks!
If proposed residential area will be developed till development of your project than you can count this in option 2. But if it is proposed will not be developed till your project get operation, you can not count this..
We have a project in which a residential area is under construction and within the half mile radious but will not be ready until Nov. 2014 and our CI project has been completed April 2013, if it meets the 10 units per acre would this qualify for the residential area?
The reference guide says that up to 2 of the basic services can be anticipated as long as they will be operational within 1 year of occupation of the LEED project. It looks like you are not within that one year range assuming project completion and occupancy are close together. While the reference guide does not explicitly state that the residential component can also adhere to this same standard, I am guessing that if you met the 1 year requirement, you could use the anticipated residental area if it met the density requirements.
Opt. 2: Average density residential area
We have a project in the center of Paris where we want to pursue option 2 of this credit.
As the area within 1/2 mile is a mixed zone (offices, shops, appartements), it is difficult to obtain the information about the density of units/acre. Options like counting the units from one highrise condo do not exist as there are no pure residential buildings. What do you recommend in that case?
Is it generally possible to pursue this credit if there is no residential area but just mixed areas?!
Is it possible to use the population density for this area to determine the apartement density by a typical person/household figure?
Any ideas?
Marco, density is notoriously hard to document. There is a LEEDuser tipsheet at the top right of this page with some tips—but there's no getting around inherent difficulties. An estimate based on population is not likely to be accepted—although you could try. Whether it's possible to earn the credit with a mixed area—it's likely, but it depends on the specifics.
Residential district density
We have recently received final design review for our CI project, but the reviewer has denied SS Credit 2 Development density because of just figure not mentioned for residential district density. We had adopted option2 of community connectivity, we had marked nearby two residential districts, but actual per acre net density not mentioned due to non availability of information. Because of this reviewer has denied credit. Please anyone suggest how can we get this credit, or can we submit this credit again in construction preliminary review submission??
I'm assuming that you've looked at the zoning definitions to see if they list density minimums. Any apartments or senior living facilities within your radius? Have you tried to see if you can calculate this by looking at the map and counting the houses?
You can appeal this credit but you want to make sure you qualify before you do.

In a LEED certified building
Hi all,
We have a CI project in a CS v2009 certified project which achieved the development density points. Do we have document this credit again?
Actually this question is a part of a more general question which applies for transportation credits, environmental tobacco smoke control, storage of recycables etc. these credits are all documented by the base building. Do we have to prepare documentation for all them again?
Thank you very much!
Aaron, sorry for the slow reply to your question. Yes, you need to document all these credits. The bonus you get for being in the LEED-CS building is covered by SSc1. If you can gain access to the documentation completed by the CS building, that may also be a help.
SSc2 Option 1 Development Desity
Do all the buildings within the Density Radius have to be part of the calculation?
Andrea, while it's assumed that all the buildings in the radius would be included in the calculation, I don't see any issue with not including some of them, if the buildings you are including put you well over the credit threshold for density.
SSc2 Option 1
Where do you find the each site's area/acres and building's square feet within the project's density radius?
Andrea, The most reliable source is the government tax rolls which have to be public. Google Earth has 'Property Owner Points' which will tell you who the tax bill is sent to and the land area. You can then call the management firm to see about how large the building is. You may not get good information from the management company. Try asking for a Green Leasing Agent who will hopefully be more sympathetic to your cause.
Documenting the credit...
I am currently submitting for a LEED CI v3.0 project and need to document the Development Density. I have no issues with Community Connectivity. That being said, how do I find the numbers that are needed to answer the following questions on the LEED Template:
Average property density within density boundary (sf/acre)

Density radius (linear feet)
A map will visually illustrate that my project easily meets this credit, I just need to find out how to obtain the numbers to complete the template to confirm that I have met the credit. Thanks!
Jennifer- You should be able to find both of these answers in the reference guide. The density radius equation is based off project site area and gives a radius in linear feet...
Density Radius (lf) = 3* sqrt{site area(acres)*43560(sf/acre)}
Average property density (within that boundary/radius) is determined by summing each property's building area/site area. NYC has an interactive map which makes finding this info veryvery easy (http://gis.nyc.gov/doitt/nycitymap/)...
Development Density (sf/acre) = Gross building Area (sf) / Site Area (acres). The documentation toolkit tab here has a step by step guide to creating a density map if that is useful
Hopefully that answers it!
Kate, thank you. I understand how to actually calculate all the numbers. The issue I have in Los Angeles, especially in unincorporated cities, is getting access to the surrounding buildings' information. I was wondering if there was a tool I didn't know about like a special feature in google earth that ties into density. It is one of those credits that can be especially easy in the right city, or terribly hard in others based on what information that city has available online. I appreciate the step by step guide to creating a density map though. Very helpful!
Jennifer, Do you think that your project will qualify for the 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. credit? If yes, then keep pursuing the information. If not, document the credit with Community Connectivity and be done. Most of our projects don't qualify for the EP credit so we document this credit via Community Connectivity as a general rule.
Public tranportation Access
We have a bus stop right outside our door and a second route a mere .32 miles away, will that be acceptable, how hard and fast is the 1/4 mile rule? We are only talking 380' which is only 8 houses in my neighborhood.
It depends - you might be able to argue the level of transit service is equivalent, but you need a lot of data to make that case. See several discussions posted under CI 2009 SSc3.1 and NC 2009 SSc4.1. Hope that helps!
SSc2 Option2
Does the entire residential area within the 1/2 mile radius need to be 10 units per acre or more or just a selection of higher density housing choices within the 1/2 mile radius?
Holly, I don't think I understand what you're getting at. Can you try rephrasing your question?
As i understand it, you only a portion of the residential area within your 1/2 mile radius.
LEED for Retail: CI
I am working on a Retail:CI project and we are attempting the documentation for the SSc2 Option 2. In the credit form on LEEDOnline, it is asking for a Unit/Acre calculation to be entered in a green box. The point says it requires "the project space is located in a building that is within 1/2 mile of a residential zone or neighborhood with an average density of 10 units per acre net..." I am not clear on how to verify this and to calculate it. Any help would be much appreciated.
For reference, I am aware of the second part of option 2 that requires the 10 basic services. I have already documented this part of the point.
Thanks for your help.
Kory - one quick & simple way would be to go into Google Earth and mark out the 1/2 mile radius from your project site. If you notice any residential multi-story complexes such as high-rise condos or even low-rise apartments this is your best bet - it can be hard to comply with the 10 units/acre with a typical subdivision filled with single-family homes and standard sized yards. Zoom in on the residential area and take an area measurement of the property to get the acreage of the complex. To get the number of dwelling units, you could look up the complex's phone number and call the front desk/rental office. That's the simplest way I've found. Good luck!
Thanks for the help.
I have one question to clerify. The approach you are talking about is just looking at the one building. Given the language I am looking at, it say "the project space is located in a building that is within 1/2 mile of a residential zone or neighborhood with an average density of 10 units per acre net..." In this language, can I define residential zone as a single apartment building? If there is more than one residential area within the 1/2 mile do I have to consider the whole thing a residential zone?
In addition to the GoogleEarth strategy you suggested, isn't some of this information a matter of public record? Would someone like a city planning department or a county auditor's office be able to help in any way?
Finally, if I were to go the other route toward Option 1 and were to try and find SFs, how would I go about doing that?
It seems reasonable for single apartment building to count for the residential requirement if the number of units and it's site area meet the 10 dwelling units per acre (DUA) ratio.
True, in some cities, this kind of information is easy to access on line from the city or planning department's website, but not all cities make this kind of GIS data easily accessible on line. You could try calling the planning department to see if they'll give you the information you need.
To your final question, we've typically gotten the building and site area data for buildings from land use data that was available online from the city GIS or planning department.
Exemplary Perfromance
Hi,
Is it possible to get an ID 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. for this credit? I thought it wasn't but the form seems to indicate that it possible. If it is, then what are the requirements?
Thanks
Méabh, the EP requirements are shown above in the Bird's Eye View.
I had the same question as M. Browne. I am also new to LEED User and am not sure the Bird's eye view is. Please elaborate.
Under the Bird's Eye View tab above, to the right there is a little blue EP ribbon, this signifies 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.. For this credit it begins with "Sit is previously developedPreviously developed sites are those altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Previously developed land includes a platted lot on which a building was constructed if the lot is no more than 1 acre; previous development on lots larger than 1 acre is defined as the development footprint and land alterations associated with the footprint. Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development."..."
For Option 2, the credit
For Option 2, the credit requirements states:
-locate the project within 1/2 mile of residential area
-locate the project within 1/2 mile of 10 services
-has pedestrian access between building and the services
We are within a 1/2 mile of a residential area and 10 services but only the services are accessible by pedestrians. There is a large highway between the project and the residential area. There is an overpass but does not have a walkway.
Does this comply since the requirements only state pedestrian access for the services?
I assume that occupants from other commercial buildings adjacent to yours would be able to access those same services in your radius. So I would say that your project would comply with the credit. SSc2 pushes for the amenities to have public and pedestrian access. There is no mention in the credit that the occupants from residential area have to have the same pedestrian access to same amenities.
Thanks Larry. Yes, the services are accessible to other office occupants as well as ours. The focus of my question is that since the credit requires proximity to 10 services and a residential area, do both of these have to have pedestrian access to our project? I agree with you that the credit does not mention this, but is the intent to have walkability to services only or to services and residential?
Occupants only need pedestrian access to those services from your building/project. Currently, there is no addenda or Interpretations that require pedestrian access to the residential area as well.
Basic services within the same shopping center
The LEED CI 2009 reference guide states that the project building itself cannot be considered 1 of the 10 basic services; however in a mixed-use building, a maximum of 1 service wtihin the building may be counted as 1 of the 10. The new LEED CI retail supplement does not provide any additional detailed guidance on this credit (only a "requirements" page is included).
I am working on a tenant finish out in a retail shopping center (not mixed use, no residential space is included). Does this mean that none of the other spaces in the retail shopping center can count towards the 10 basic services?
It seems counterintuitive that we would be able to count services from the business that are located on padsites across the parking lot, but not within the same shopping center our project is located in. I tried finding 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 could not find one.
I don't see why it would be a problem, assuming those other businesses in the shopping center are already existing.
Alison, we have the same question as you do? how did you do this in the end? Our 10 basic services (except for the church and the school) are inside our mall, and it doesn't have any residences or weird things, it is just a huge mall full of retail spaces (and basic services)
Project boundary within an existing building
Hi - when doing the calculations for option 1 - should i include the sf of the project (ie 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.) or the whole building - then divide it by the area. The project uses 10 floors of a 30 floor existing building - either way the calculation will be more than 60,000sf but i am unsure which figure to use.
thanks
You'd want to use the sf of the whole building, since that contributes to the density of the area within the radius. That way it wouldn't matter if your project is one floor or umpteen floors.
Thumbs up David, thanks
Unit Clarification
I wanted to know if anyone could tell me how many units you need in a half a mile radius. I am a little confused on how to calculate the 10 units per acre.
Heather, it depends on the neighborhood. One 10-unit apartment building would do it. Or another kind of development or neighborhood with 10 units within one acre. What's your situation?
Hi Tristan,
So, to clarify your reponse to Heather's post above, would it be sufficient to provide only the number of units per loft/apartment building if there are more than 10 loft/apartment buildings located within the 1/2 mile radius?....Rather than calculating the 10 units per acre for each building...?
-Thanks in advance
Gail,
On the Credit Form, it does not ask you to provide the density/acre anymore - the actual number as in v2.0. It does ask for a map link or for the project team to upload their own map. Here, as long as you highlight the building/buildings within 1/2 mile of your site that meet the density requirement, you'll be fine, i.e. the 10+ unit apt building. What you could also do, is check your local zoning map and definitions and use this as a reference when creating your documentation.
Basic Services of a College Campus
The project I am working on is part of a University and is on the outskirts of the main campus of where I could get my 10 basic services no problem what so ever, would any of the college campus amenities count? For example the student recA Renewable Energy Certificate (REC) is a certificate representing proof that a given unit of electricity was generated from a renewable energy source such as solar or wind. These certificates are able to be sold, traded, or bartered as environmental commodities, where an electricity consumer can buy the renewable energy attributes of electricty to support renewable energy, even if they are consuming generic grid-supplied electricity that may be supplied by nonrenewable sources. center, Auditorium etc? Another service I have a question on is if an Insurance company would be considered a basic service?
I don't think you could count an insurance office as a basic service, no. You are pretty much restricted to the list shown in the credit language (see above).
As for the campus services, if this are on the list above, and operated like centers that are open to the public and have regular hours, then yes.
The center is open to the public but have to pay a membership fee and have to have a referral. Would that still count?
Fitness centers are on the approved list in the credit language, and I think it's fairly universal that membership fees are required. So yes, that sounds fine to me. I'm not totally sure about the referral—if that makes it more of an exclusive club, I would not be so sure.
I just had this credit denied because it is on a state university campus, the reviewer says that these services like the campus police and fire departments, gym, library etc - they say these are not open to the public......I thought the intent of this credit was to create an operation where occupants have close proximity to services....and isn't a State campus open to the public......
Basic Services
A few quick questions.
First: how strict is the USGBC on types of services and do they have to be on the "Example" list?
Second: can you count 3 restaurants count as 3 of the 10 or can you only count one service once?
A project can count only two restaurants toward the ten services.
Andrew, I think you'll find this discussion on the NC forum for this credit quite helpful.
What services did you have in mind?
Thank you Jim and Tristan.
On Jim's comment, can you only double up on one of the 10? For instance can you count 2 restaurants, 2 supermarkets, 2 libraries, etc?
On Tristan's comment, other services I was considering are: coffee, bookstore, large mall (department stores, clothing, electronics, sporting goods, etc)...
There is a specific exception allowing two restaurants to be counted.
Coffee sounds like too similar to restaurant to me.
I doubt that a "mall" could be considered a service but perhaps some of the stores if they qualify.
I think you may be able to get some traction with these but I would be a bit concerned about the consumer focus. Many of the basic services listed in the credit language are just that—key services needed for life. I haven't seen this articulated as a requirement—just a thought in terms of what you choose to submit with.
USGBC recently clarified that three restaurants can be counted for LEED-CI.
JIm, that's very interesting. Where did this clarification appear?
This is now twenty months old, so does that mean that the three restaurant option was never verified? My early copy of the LEED-CI reference guide clearly indicates two.
Hi Brian - I have never heard of the clarification allowing more than 2 restaurants to count and a quick search of the interpretation and addendum database turns up nothing. Hopefully Jim can show us where he saw this clarification?
I know this thread is old but seems an appropriate to my question. In the LEED - CI reference guide the example they give lists one dental office and one medical office (but they also list 12 basic services). If you have just ten services can one be a dental office and one a medical one, though those two are listed as a single item on the credit criteria?
I have never noticed that before - good catch! However, the examples of basic services that they outline in the requirements section clearly states medical or dental office, so my guess is that you can only use one or the other to get to 10.
Density and Vacant Land
Does privately held vacant land need to be factored in to the density calculations? In the area there is a 18000 square foot of land with no building on it, should we include this?
Yes, Otherwise you could be the first to develop a project in the middle of an undeveloped track and still potentially get the credit.
If there are development plans on file with the city, or if a developer in currently working on developing the site you might be able to include the anticipated density and opening date in your documentation, but I would expect it to raise a question or two during the audit.
