The General Services Administration’s Net-Zero Energy Task Group is working on a draft letter with clear goals and guidance for net-zero energy buildings by this September. The committee recently created a provisional definition of net-zero energy buildings (NZEBs).
The draft definition distinguishes between two different types of net-zero buildings:
- NZEB: an energy-efficient building where the actual annual source energy consumption is balanced by on-site renewable energy.
- REC-NZEB: an energy-efficient building where the actual annual source energy consumption is balanced by on-site renewable energy to the maximum extent possible and is augmented by off-site renewable energy and Renewable Energy Credits (RECs) from certified sources.
GSA’s Net-Zero Energy Task Group is part of the Green Building Advisory Committee, which advises and helps agencies build more sustainably. In its draft, the committee has recommended that net-zero buildings reduce energy use by 50% or more than typical buildings of similar types.
