Retail-EBOM-v4 MPR3: Must comply with project size requirements

  • The evolution of MPRs in LEED

    Minimum Program Requirements (MPRs), which set literal and actual boundaries for how LEED certification should be applied, continue to evolve in LEED v4. Here's a short history so far:

    • Pre-LEED-2009: no MPRs
    • LEED 2009 (LEED v3): MPRs introduced, with 7 in most rating systems. Supplemental guidance introduced and modified over time as MPRs proved confusing.
    • LEED v4: MPRs more integrated into rating system, reduced to 3.

    What to look for in LEED v4

    The requirements conveyed by the LEED 2009 MPRs have not changed in LEED v4.

    However, USGBC has made structural changes to the MPRs in order to maintain alignment with the overall evolution of the rating system. Some MPRs have been relocated to other documents (like a legal form) and some have been incorporated into the rating system as prerequisites. The MPRs that remain more clearly represent the foundational nature of these requirements.

    Supplemental guidance embedded in requirements

    If you're looking to interpret specific requirements of an MPR, look in the MPR language itself (see the credit language tab) under "Additional Guidance," where applicable, rather than in lengthy supplemental guidance documents.

  • MPR 3: Must comply with project size requirements

    Intent

    The LEED rating system is designed to evaluate buildings, spaces, or neighborhoods of a certain size. The LEED requirements do not accurately assess the performance of projects outside of these size requirements.

    Requirements

    All LEED projects must meet the size requirements listed below.

    LEED BD+C and EB:O&M Rating Systems

    The LEED project must include a minimum of 1,000 square feet (93 square meters) of 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.).

    LEED ID+C Rating Systems

    The LEED project must include a minimum of 250 square feet (22 square meters) of gross floor area.

    LEED Neighborhood Development Rating Systems

    The LEED project should contain at least two habitable buildings and be no larger than 1500 acres.

    LEED for Homes Rating Systems

    The LEED project must be defined as a “dwelling unit” by all applicable codes. This requirement includes, but is not limited to, the International Residential Code stipulation that a dwelling unit must include “permanent provisions for living, sleeping, eating, cooking, and sanitation.”
