This Bird's Eye View text is from USGBC's MPR Supplemental Guidance Revision #2. See the Credit Language tab for the MPR requirements.
The goal of decreased energy and water use consumption is a major component of LEED certification. Tracking actual building consumption and comparing it to the usage proposed in design cases, or tracked during a performance period, is essential to the individual success of each LEED certified building and the ongoing evaluation and development of the LEED program.
By providing usage data, LEED project owners will not only be taking a very active part in advancing the green building movement, but they will also be provided feedback about the performance of their building in the context of comparable buildings. In addition, buildings that achieve LEED certification in a design and construction rating system will be able to streamline their certification under LEED-EB: O&M with readily available performance data.
Access to complete and accurate performance on every LEED building project will allow the USGBC to aggregate individual building information and perform program evaluations, such as average LEED energy and water savings relative to national and regional averages. Aggregate figures on carbon emissions, costs, and other environmental impacts associated with building energy usage are of significant interest to USGBC, GBCI, green building advocates, builders, owners, and operators. USGBC will use all building data to inform the continuous improvement of the LEED rating systems, develop related educational programming, identify key areas of needed research, and present clear, unbiased results to the building community. Building performance feedback will be provided to LEED project owners as part of this MPR.
When whole project meters are cost-prohibitive or physically impractical to install
Owners of LEED project buildings or spaces that do not have meters in place that measure energy and/or water usage for the entire LEED-certified gross floor area are not expected to supply energy and/or water usage data unless such meters are installed. Many commercial interiors projects, higher education campuses, and military bases will fall into this category. In PIf1 in LEED Online v3, the project team will need to detail the reasons why whole project meters are cost-prohibitive or physically impractical to install.
If meters are installed post-certification, the project owner is expected to report data for whatever time is remaining on the 5 year period, which begins at the beginning of typical physical occupancy for design and construction projects and the date certification is awarded for LEED-EB: O&M projects.
Complying with this MPR when there is a transfer of ownership
To own a LEED certified project is to participate in the ongoing evolution of the green building movement. In that spirit, and in keeping with the intent of this MPR, the owner’s commitment to provide whole-building energy and usage data is expected to carry forward to the next owner if all or part of a LEED certified project is sold, re-assigned or otherwise transferred. However, it is recognized that this may not always be possible, and USGBC will respect the realities of situations in which reasonable efforts to maintain the commitment are not successful. In this situation, the initial building owner will no longer be required to provide the data or access to the data.
Correlation of actual performance to design performance is not required
Data collection is for research purposes only, and project teams are required simply to share data, NOT to show that design cases submitted during certification were accurate. For projects using rating systems other than LEED-EB: O&M, actual performance may vary from projected performance. This MPR addresses the act of data sharing, not the content of the data. Projects will not be de-certified based on performance.
NOTE: projects certifying under LEED-EB: O&M are required to submit performance data during the certification process, and this does affect if, and what level of, certification will be achieved.
The reporting timeline for design and construction projects
For projects certifying under design and construction rating systems, data tracking must begin when the project reaches 50% of typical physical occupancy, and the first data report must be submitted within two months of that date. However, project teams can begin tracking any time before that, and are encouraged to do so. If tracking begins prior to 100% typical physical occupancy, project teams are asked to make note of occupancy rates in the tool they are using to submit data.
Project teams should submit data on a monthly basis unless they are unable to do so because of a utility billing cycle. In this case, submissions aligning with that cycle are acceptable.
How to determine typical physical occupancy
The definition of ‘Typical Physical Occupancy’, as given in the definitions section below, is: “The state in which normal building operations are underway and the building is in use by the average number of people that it was designed for.”
To determine the average number of full time equivalent occupants that the building was designed for, project teams must assess buildings on a case by case basis, using reasonable judgment. Design intentions, floor area capacity, and building system capacity must all be considered.
The process of data collection
All project teams (including international project teams) have three options for sharing data with USGBC. These choices are indicated on PIf1in LEED Online v3. For details on the MPR#6 Options, refer to the Sample Form download section of LEED Online v3 and the MPR#6 FAQs located on the LEED 2009 Minimum Program Requirements page at usgbc.org.
How to change compliance method post-certification
Project teams can change their method of data sharing at any time by contacting LEEDPerformance@usgbc.org.
Publication of data will be anonymized
Analysis of aggregated data will be made publicly available on a regular basis (schedule to be determined).
Commercial Interior projects should report data only for LEED space
LEED-CI projects need not, and should not, report data unless there are meters in place that can measure usage for the entire LEED project space, and only the LEED project space.
LEED Core & Shell projects do not require special treatment
Metering and data collection for LEED-CS projects does not differ from other projects. Data may be collected from spaces that the LEED project team did not fit out as part of their core and shell design and construction – this is normal and acceptable.
Major renovations negate the need to report data
If the LEED project building undergoes a post-certification renovation or change significant enough to alter the energy and water usage patterns, than data sharing is no longer necessary.
Reporting periods are not additive for buildings certifying multiple times
The data sharing ‘clock’ starts over each time a building is certified. If, for example, a building certifies under a design and construction rating system, and then certifies under LEED-EB: O&M three years later, the project owner is only required to report five years of data from the date of LEED-EB: O&M certification, not seven years.
Data Reporting with the Building Performance Partnership
MPR#6 data-sharing requirements is not the same as participating the Building Performance Partnership (BPP). Read more about the BPP program at usgbc.org/bpp.
Excerpted from LEED 2009 for Commercial Interiors
All certified projects must commit to sharing with USGBC and/or GBCI all available actual whole-project energy and water usage data for a period of at least 5 years. This period starts on the date that the LEED project begins typical physical occupancy if certifying under New Construction, Core & Shell, Schools, or Commercial Interiors, or the date that the building is awarded certification if certifying under Existing Buildings: Operations & Maintenance. Sharing this data includes supplying information on a regular basis in a free, accessible, and secure online tool or, if necessary, taking any action to authorize the collection of information directly from service or utility providers. This commitment must carry forward if the building or space changes ownership or lessee.
I work in a project of a multi-family residential building. I have a doubt to fill item 6. This project will be sold out, so we would not have how commit to shared whole-building energy and water usage data. According the template, They said that if the project is sold, then I will no longer be required to provide the data.
If i filled item 6 and i explain my problem at the 'additional details', it will be ok? I will satisfy this pre-requisite?
One of the projects I'm working on in Peru, is persuing the option 1 of MPR#6 (through Energy Star Portfolio Manager:ESPM) so we can get one EP point in EAc5.1. So, my questions are:
1. Just to confirm, does the ESPM for sharing the energy and water consumption data work for projects outside the US as well?
If so, when I'm asked for the ZIP code, should I write an arbitrary ZIP code of a US state with the same climate than Lima (2A) according to ASHRAE 90.1-2007?
2. Is there any other important issue about Portfolio Manager Energy Star for international LEED projects that I can take into consideration?
Thanks in advance.
We commit to allowing USGBC to have access to our energy and water meter data from the Utilities. Does USGBC follow up and collect this building data for all v2009 projects?
We are working on a municipal water processing plant. A huge amount of water courses through the plant, while only a tiny fraction is used by the plumbing fixtures, and similarly, a process energy exceeds building systems energy by perhaps 1000:1. GBCI has indicated that we do not need to add meters to separate these loads. The only utility meters are for the whole site ; multiple industrial facilities. So, when we are filling out MRP6, which of the 3 reporting options do we choose, and how will the facility report, or would they not report?
Under these circumstances, is the 1 point for reporting in EAc5 possible to get?
Susan, I would assume that the facility would not report, and the EAc5 point is not applicable. But that's just my educated guess.
I am currently working on a LEED-NC 2009 Multiple Building Project. We are having a problem with MPR 6; commit to showing whole-building energy and water use data. The owner spoke to Energy Star about the Energy Star Portfolio Manager and found that you cannot set up an account for a building that has a future construction date. How has this been handled in the past? Are we to just wait to set up the Portfolio Manager until the building is constructed? How do we submit our design credits if we do not even have our Minimum Program Requirements met?
Cassandra, the EPA is likely referring to the fact that Portfolio Manager is meant for existing buildings, whereas other tools (such as Target Finder) are more geared to new construction. You can still set up the under-construction building in Portfolio Manager with the information you have currently (i.e. square footage, address, building space type, etc.). You can then share the building with the USGBC's master account. This is an accepted approach to meeting MPR 6.
Courtney, we have a similar situation to yours in that we do not have access to whole building utility data.
We are currently in the process of certifying several large multi-family projects under LEED NC 2009. Requirement #6: Sharing Energy and Water Data requires that "all available actual whole-project energy and water usage data" be shared for a period of five years post-certification. This presents a serious challenge (if not impossibility) for our projects since the utility does not allow us to install a submeterSubmetering is used to determine the proportion of energy or water use within a building attributable to specific end uses such as tenant spaces, or subsystems such as the heating component of an HVAC system. on the incoming switchgear for dwelling units. On a side note, it is extremely disappointing that the utility does not allow this (we wanted to be prepared for ENERGY STAR Certification for existing multi-family buildings which is rolling out this year). The only other available option is to install a submeter on each dwelling unit which represents hundreds of submeters per project.
The language also states that "I understand that if my project does not have meters in place that measure energy and/or water usage for the entire LEED certified gross floor areaGross floor area (based on ASHRAE definition) is the sum of the floor areas of the spaces within the building, including basements, mezzanine and intermediate‐floored tiers, and penthouses wi th headroom height of 7.5 ft (2.2 meters) or greater. Measurements m ust be taken from the exterior 39 faces of exterior walls OR from the centerline of walls separating buildings, OR (for LEED CI certifying spaces) from the centerline of walls separating spaces. Excludes non‐en closed (or non‐enclosable) roofed‐over areas such as exterior covered walkways, porches, terraces or steps, roof overhangs, and similar features. Excludes air shafts, pipe trenches, and chimneys. Excludes floor area dedicated to the parking and circulation of motor vehicles. ( Note that while excluded features may not be part of the gross floor area, and therefore technically not a part of the LEED project building, they may still be required to be a part of the overall LEED project and subject to MPRs, prerequisites, and credits.), I will not be required to supply energy and/or water usage data unless and until such meters are installed." Does this mean that we can avoid submeteringSubmetering is used to determine the proportion of energy use within a building attributable to specific end uses or subsystems (e.g., the heating subsystem of an HVAC system). each unit? At the very least, I would think that we could meet this requirement by requesting aggregated utility data from the utility.
We are currently working on a Core & Shell project where a single tenant will be occupying the entire building. That tenant is also going for LEED under Commercial Interiors. Their lease is structured so the tenant will pay for the entire building energy and water use. The C&S owner will not receive any of the bills. We would like to claim an exemption for Minimum Program Requirement 6: Whole Building Energy and Water Usage Data based on the fact that all of this information will be submitted by the tenant under their CI certification.
Has anyone had any experience on this type of approach?
Did you ever receive offline feedback or pursue the submittal as such? I have a current project under similar circumstances. It is a single tenant retail LEED-CS building where the building utilities will be paid directly by tenant. Landlord's utilities will only consist of parking lot lighting and miscellaneous fountains tied to larger/existing parking lot electrical meter. It seems inappropriate/unreasonable for the landlord to contractually require post-occupancy utility reporting by the tenant. Does anyone have experience with this?
