News on this has been trickling out for a little while now, but I wanted to put up an official information announcement here on LEEDuser: parking garages are specfically excluded from eligibility for LEED certification, as of a LEED InterpretationLEED Interpretations are official answers to technical inquiries about implementing LEED on a project. They help people understand how their projects can meet LEED requirements and provide clarity on existing options. LEED Interpretations are to be used by any project certifying under an applicable rating system. All project teams are required to adhere to all LEED Interpretations posted before their registration date. This also applies to other addenda. Adherence to rulings posted after a project registers is optional, but strongly encouraged. LEED Interpretations are published in a searchable database at usgbc.org. issued on May 9, 2011. That means that any parking garages registered before that date are fine to proceed, but anyone trying to register after that date are out of luck.

Parking garages are defined as "buildings that dedicate more than 75% of floor area (including areas not covered, enclosed, or conditioned) to the parking and circulation of motor vehicles."

More useful parking garage info from the LEED MPR Supplemental Guidance:

Parking garages may not be included in the 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.) of the LEED project building.

Parking garages may be included within the LEED project boundary—if parking is within, connected to, or on the site of the LEED project building.

Does this news affect your project? What do you think of it?

GFA and other usage types on underground parking storey

This isue can be very confusing when it comes to detail.
1.
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.) (based on ASHRAE definition) sais that the calculation "excludes floor area dedicated to the parking and circulation of motor vehicles". Typically, on underground parking floors, there are rooms with other usage type.
In our project (Retail and Office-Mixed Use) there is a 3-storey underground parking lot with circulation, but there are also technical rooms (AHU1.Air-handling units (AHUs) are mechanical indirect heating, ventilating, or air-conditioning systems in which the air is treated or handled by equipment located outside the rooms served, usually at a central location, and conveyed to and from the rooms by a fan and a system of distributing ducts. (NEEB, 1997 edition) 2.A type of heating and/or cooling distribution equipment that channels warm or cool air to different parts of a building. This process of channeling the conditioned air often involves drawing air over heating or cooling coils and forcing it from a central location through ducts or air-handling units. Air-handling units are hidden in the walls or ceilings, where they use steam or hot water to heat, or chilled water to cool the air inside the ductwork., utility connections, chillers), vertical communication (stairways), changing rooms and showers for bicycle users, stuff rooms, storage rooms etc. Usable floor area of these rooms should be substracted from gross floor area calculation and include only parking places with circulation (exterior faces of exterior walls)?
2.
It also sais that the calculation "excludes air shafts, pipe trenches, and chimneys". Does this also apply to internal shafts and chimneys (clear dimensiohttp://www.leeduser.com/sites/all/themes/leeduser/images/form-submit.gifns) and each should be substracted from the gross floor area calculation?

Do parking garages need to be included in the LEED project?

We have a project that is being designed, and there is a parking garage being build on the site as well. The garage will be supporting the LEED building 100% (meaning no other buildings will be using the garage). Do we need to include the materials and the energy use of the garage with our LEED project, or is the garage not included whatsoever? The project is LEED 2009 BD+C.

Mark, the answer would typically be "yes." Check the LEED Minimum Program Requirements Supplemental Guidance Document for a deeper understanding of this.

The MPR Supplemental Guidance states garages cannot earn LEED certification, they can't be included in the 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 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.) of the LEED project building, and they may be included within the LEED Project Boundary. It doesn't state if their materials and energy should be included with the LEED project building. It appears this may be 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 item.

My reading of the MPRs is that the exclusion of parking garages is only for LEED certification on their own, and for 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 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.) as part of the occupied space. They are integral to supporting the project building and should be included in all relevant credits, as would other site features.

I am working on an office building project that includes a significant parking garage, both under the building and to the side of the building. The reviewer asked us to be sure to include the parking garage in the lighting calculations as well as other energy calculations. This corroborates Tristan's recent comment.

MPR supplement re parking garage no longer cerifiable

The change applied to parking garage certification is unfortunate and short sighted. the 75% rule appears also to apply to warehouse, transportation centers, and other spaces that contribute to the triple bottom line as well as global climate change1. Climate change refers to any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). (U.S. Environmental Protection Agency, 2008) 2.The increase in global average temperatures being caused by a buildup of CO2 and other greenhouse gases in the atmosphere. This temperature change is leading to changes in circulation patterns in the air and in the oceans, which are affecting climates differently in different places. Among the predicted effects are a significant cooling in Western Europe due to changes in the jet stream, and rising sea levels due to the melting of polar ice and glaciers.. Parking garages preserve space for alternative uses with its high density getting cars off the street, open space parking, storm water management and countless other benefits. Parking garages meeting MPR (namely 1 FTEFull-time equivalent (FTE) represents a regular building occupant who spends 8 hours a day (40 hours a week) in the project building. Part-time or overtime occupants have FTE values based on their hours per day divided by 8 (or hours per week divided by 40). Transient Occupants can be reported as either daily totals or as part of the FTE. Residential occupancy should be estimated based on the number and size of units. Core and Shell projects should refer to the default occupancy table in the Reference Guide appendix. All occupant assumptions must be consistent across all credits in all categories.) could be relegated to CI certification but BD+C should apply so long as minimum program requirements are met.

request clarification for reversal or recommendation to use CI for new parking structure certfication.

Joseph, our website is independent from USGBC and GBCI, so they will have to give you a definitive answer.

However, based on the LEED InterpretationLEED Interpretations are official answers to technical inquiries about implementing LEED on a project. They help people understand how their projects can meet LEED requirements and provide clarity on existing options. LEED Interpretations are to be used by any project certifying under an applicable rating system. All project teams are required to adhere to all LEED Interpretations posted before their registration date. This also applies to other addenda. Adherence to rulings posted after a project registers is optional, but strongly encouraged. LEED Interpretations are published in a searchable database at usgbc.org. that provided this ruling, I don't see how LEED-CI is any different from BD&C. The ruling is based on the percentage of the project devoted to parking.

To those who are wondering why USGBC made this ruling, I can only speculate. But here is my guess (and I will make no comment on whether I agree or not):

LEED was not developed for unoccupied structures, including parking garages. USGBC is not saying that parking garages are never "green," nor that one parking garage cannot be "greener" than the other. They are simply saying that the current LEED rating systems aren't suited for this building type, and they don't want to see them used this way for the time being.

There are major organizations devoted to parking garages. If USGBC doesn't want to work in this area, I would look to those groups to develop LEED-like standards.

This is very unfortunate!

Tristan:

Has this shown up yet in the Policy Manual or only in the LEED InterpretationLEED Interpretations are official answers to technical inquiries about implementing LEED on a project. They help people understand how their projects can meet LEED requirements and provide clarity on existing options. LEED Interpretations are to be used by any project certifying under an applicable rating system. All project teams are required to adhere to all LEED Interpretations posted before their registration date. This also applies to other addenda. Adherence to rulings posted after a project registers is optional, but strongly encouraged. LEED Interpretations are published in a searchable database at usgbc.org. dated May 9, 2011 as you've cited?

This is unforutnate since motor vehicles aren't going away anytime soon, as much as we'd like to think otherwise.

The thoughtful and creative sustainable strategies extended to the design of parking structures can significantly REDUCE the impact of vehicles on the environment and WHY shouldn't they receive the same certification opportunities? Why should the structure itself be penalized for what is housed within it?

Let me give you an example: we received certification for the BCBSM parking structure project in Detroit in 2007. On the same site that previously accomodated only 125 surface parking spaces, we constructed a parking structure that provides for over 1800 spaces ON THE SAME SITE! Talk about density and the ability to maintain open land for other Civic/landscaping opportunities! We also installed the 2nd-largest green roof in the State of Michigan on top of this deck in order to not only provide an area for a walking track for BCBSM's employees, but also to assist in our overall storm water catchment system which is considerable!

Why shouldn't these same strategies that apply for other (non-parking) structures NOT earn certification for these structures!

We are so disappointed! Is this written in stone?

I see a wave of backlash coming!

If what you say is true, there is no motiviation in the industry to make these structures anything other than dumb-boxes.

There is a clarification in the MPR guidance update (June 1, 2011) which states that parking garages may not be included in the gross floor area. However, the original MPR guidance (Nov 1009) is not as clear.

Kathy, I don't know what you mean by the "policy manual"—I don't think there is one.

Tristan, do you know if this interpretation has been altered at all? Any other updates that would change the fundamental outcome that stand-alone parking structures are NOT eligible for LEED certification?

No, I'm not aware of any change to this. You can double-check the LEED Interpretations database at USGBC.org, however.
