Hospitality-EBOM-v4 MPR2: Must use reasonable LEED boundaries

  • 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 farFloor-area ratio is the density of nonresidential land use, exclusive of parking, measured as the total nonresidential building floor area divided by the total buildable land area available for nonresidential structures. For example, on a site with 10,000 square feet (930 square meters) of buildable land area, an FAR of 1.0 would be 10,000 square feet (930 square meters) of building floor area. On the same site, an FAR of 1.5 would be 15,000 square feet (1395 square meters), an FAR of 2.0 would be 20,000 square feet (1860 square meters), and an FAR of 0.5 would be 5,000 square feet (465 square meters).:

    • 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 2: Must use reasonable LEED boundaries

    Intent

    The LEED rating system is designed to evaluate buildings, spaces, or neighborhoods, and all environmental impacts associated with those projects. Defining a reasonable LEED boundary ensures that project is accurately evaluated.

    Requirements

    The LEED project boundary must include all contiguous land that is associated with the project and supports its typical operations. This includes land altered as a result of construction and features used primarily by the project’s occupants, such as hardscapeThe inanimate elements of the building landscaping. It includes pavement, roadways, stonewalls, wood and synthetic decking, concrete paths and sidewalks, and concrete, brick, and tile patios. (parking and sidewalks), septic or stormwater treatment equipment, and landscaping. The LEED boundary may not unreasonably exclude portions of the building, space, or site to give the project an advantage in complying with credit requirements. The LEED project must accurately communicate the scope of the certifying project in all promotional and descriptive materials and distinguish it from any non-certifying space.

    Additional guidance

    Site
    • Non-contiguous parcels of land may be included within the LEED project boundary if the parcels directly support or are associated with normal building operations of the LEED project and are accessible to the LEED project’s occupants.
    • Facilities (such as parking lots, bicycle storage, shower/changing facilities, and/or on-site renewable energy) that are outside of the LEED project boundary may be included in certain prerequisites and credits if they directly serve the LEED project and are not double-counted for other LEED projects. The project team must also have permission to use these facilities.
    • The LEED project boundary may include other buildings.
      • If another building or structure within the LEED project boundary is ineligible for LEED certification, it may be either included or not included in the certification of the LEED project.
      • If another building within the LEED project boundary is eligible for LEED certification, it may be either included or not included in the certification as outlined in USGBC’s campus guidance.
    • Projects that are phased sites with a master plan for multiple buildings must designate a LEED project boundary for each building or follow USGBC’s campus guidance.
    • 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 should be no less than 2% of the gross land area within the LEED project boundary.
    Building
    • The LEED project should include the entire building and complete scope of work.
    • Buildings or structures primarily dedicated to parking are not eligible for LEED certification. Parking that serves an eligible LEED project should be included in the certification.
    • Buildings that are physically connected by programmable space are considered one building for LEED purposes unless they are physically distinct and have distinct identities as separate buildings or if they are a newly constructed addition. If separated, the projects should also have separate air distribution systems and water and energy meters (including thermal energy meters).
    • Buildings that have no physical connection or are physically connected only by circulation, parking, or mechanical/storage rooms are considered separate buildings and individual projects for LEED purposes, with the following exceptions:
      • Primary and secondary school projects, hospitals (general medical and surgical), hotels, resorts, and resort properties, as defined by ENERGY STAR building rating purposes, may include more than one physically distinct building in a single LEED project. For new construction projects, each building in the application must be less than 25,000 sq. ft. Please contact USGBC if with any questions.
      • For other cases such as buildings that have programmatic dependency (spaces – not personnel – within the building cannot function independently without the other building) or architectural cohesiveness (the building was designed to appear as one building), project teams are encouraged to contact USGBC to discuss their project prior to proceeding.
    Interiors
    • The LEED project should be defined by a clear boundary such that the LEED project is physically distinct from other interior spaces within the building.
    Neighborhood
    • The LEED neighborhood includes the land, water, and construction within the LEED project boundary.
    • The LEED boundary is usually defined by the platted property line of the project, including all land and water within it.
      • Projects located on publicly owned campuses that do not have internal property lines must delineate a sphere-of-influence line to be used instead.
      • Projects may have enclaves of non-project properties that are not subject to the rating system, but cannot exceed 2% of the total project area and cannot be described as certified.
      • Projects must not contain non-contiguous parcels, but parcels can be separated by public rights-of-way.
    • The project developer, which can include several property owners, should control a majority of the buildable landThe portion of the site where construction can occur, including land voluntarily set aside and not constructed on.. When used in density calculations, the calculation for buildable land excludes: public streets and other public rights of way, and land excluded from development by law or other prerequisites of LEED for Neighborhood Development. within the boundary, but does not have to control the entire area.
