The January 2016 quarterly LEED rating system and reference guide addenda is now available. To view the changes,


Five new LEED Interpretations have been published (10426–10430). LEED Interpretation 10426 provides an alternative to vestibules in the design model for EA Prerequisite Minimum Energy Performance. LEED Interpretation 10430 provides an alternative way for projects that share air handling units with spaces outside of the project boundary (shared VAV systems or shared Dedicated Outside Air Systems) to obtain points under EAc3 - Measurement and Verification in LEED v2009 ID+C.


Two corrections were published for LEED v2009, and five corrections were published for LEED v4 (100002038–100002044). EQ Credit Green Cleaning—Products and Materials in the LEED v4 O+M Rating System was updated to reflect new a EPA program name: “EPA Safer Choice Standard.”

Two corrections were issued for LEED v4 Homes. Correction 100002042 clarifies the rating system requirements for Heat-Recovery Ventilators and Energy-Recovery Ventilators (H/ERVs) under EQ Prerequisite Ventilation, while correction 100002041 clarifies guidance for calculating the amount of continuous ventilation required to comply with the EQ Credit Enhanced Ventilation.
