LEED Certifications for Parking Garages No Longer Allowed
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.
