Pilot-Credits PC46: HVAC Commissioning

  • Better Design and Performance for Residential HVAC Systems

    Note: This pilot credit was closed for new registrations as of March 1, 2012.

    Most residential HVAC systems are not performing properly, many as a direct result of improper design or startup. This can impact the durability of the equipment, as well as decrease the efficiency by up to 30% or more.

LEED Pilot Credit Library

The homepage for the LEED Pilot Credit Library. The LEED Pilot Credit Library is intended to facilitate the introduction of new prerequisites and credits to LEED. This process will allow USGBC to test and refine credits through LEED 2009 project evaluations before they are sent through the balloting process for introduction into LEED.
