What LEED Green Building Rating requires
The LEED Green Building Rating system establishes a framework of performance-based prerequisites and optional credits for certifying sustainable building projects. Foundational compliance requires executing multiple non-negotiable measures, starting with verification that a site assessment is complete to inform design and that a construction activity pollution prevention plan meeting NPDES guidelines is in place. Resource efficiency mandates a minimum indoor water use reduction percentage of 20, substantiated by building-level water metering for total potable water consumption. Energy prerequisites demand a certified minimum energy performance percentage improvement over the ASHRAE 90.1 baseline, supported by building-level energy metering. System integrity necessitates fundamental refrigerant management by prohibiting any use of CFC-based refrigerants in new equipment. Occupant welfare is addressed through strict environmental tobacco smoke control, which bans smoking within facilities and 25 feet of building openings. Additionally, a dedicated area for the storage and collection of recyclables must be provided. Credits for advanced performance are attainable by achieving a high construction waste diversion percentage, increasing the number of low-emitting materials categories met to limit VOC emissions, or implementing a building automation system security protocol as an innovation strategy.
