LEED Adapting to Me

  • Actually, LEED is adapting to the world, but how does this affect us Internationally?

    Around the world, much of the grief about LEED is that it is so American centric. This makes sense for an American organization, but the reality is that in the near future non-US projects will likely surpass US ones. According to the USGBC, about 40% of newly registered are already non-US.

    In response to this, LEED is finally providing new guidelines for international projects. The integration of International Alternative Compliance Paths into the LEED credit language was the main feature of the July addenda. Here are the key points for our China users, courtesy of LEEDuser and which we have translated into Chinese.

    SSc1: Non-U.S. equivalents to definitions of flood plains, prime agricultural lands, etc, are now recognized in the Site Selection credit language. In another change to this credit, the definition of what buildings are exempt from the parkland prohibitition are broadened somewhat, in a common-sense manner.

    SSp2, SSc3: Non-U.S. equivalents to definitions of brownfields, and site assessments, are recognized.

    SSc4.1: Bus rapid transit stations and commuter ferry terminals are recognized under Option 1, which was previously reserved for rail. (This change affects all projects, not just non-U.S. ones.) In a new Option 3 available only to international projects, proximity to ride-share stations can contribute  to the credit.

    SSc6.1: Has been restructured with the previous language relabeled as Option 1: Design Storms, and a new Option 2: Percentile Rainfall Events being added. This new option doesn't appear to alter the intent or likely implenentation strategies for this credit - rather, it presents a new set of options for performing the necessary calculations and documentation.

    WEc1: Option to base calculations on the "the month with the highest irrigation demand."

    EAp2/EAc1: Non-U.S. projects may use an alternative standard to ASHRAE Standard 90.1‐2007 if it is approved by USGBC as an equivalent standard using the process located at www.usgbc.org/leedisglobal

    EAc6: Green Power no longer has to be Green-e certified, but the project must demonstrate equivalence with Green-e on the basis of: 1) current green power performance standards, and 2) independent, third‐party verification that those standards are being met by the green power supplier over time.

    MRc5: The familiar 500-mile radius is now Option 1 of this credit. There is a new Option 2, borne out of the International ACPs but affecting all projects, in which miles that projects travel by sea, rail, or inland waterway count less than miles traveled over land. The 500 mile total travel distance can be calculated using a weighted average: (Distance by rail/3) + (Distance by inland waterway/2) + (Distance by sea/15) + (Distance by all other means) ≤ 500 miles.

    IEQp1, IEQp2, IEQc1, IEQc2, IEQc3.1, IEQc4.3, IEQc5, IEQc6.2, IEQ7.1, IEQc9: For these IEQ credits, allowance has been given to alternative standars for ventilation effectiveness, air filtration, product emissions, etc. The intent and key requirements of the credits are unchanged, but non-U.S. projects will have more latitude in using locally relevant standards.
