  • Guidance classifying electronic cigarettes as a form of smoking for the purposes of both the interior and exterior smoking provisions of the EQ Prerequisite Environmental Tobacco Smoke Control (also applicable to LEED v4)
  • Guidance on classifying directed biogas purchases and how to include purchased renewables in the Energy Model
  • Clarification on how to calculate refrigerant leakage rates for LEED for Existing Buildings: Operations and Maintenance v2009, particularly when CFC-based refrigerants are maintained within a building
  • Revisions to LEED Interpretation 10244 clarifying how the commissioning agent can be included in single-entity contracting methods
