The most effective way of verifying the status of a net zero energy (NZE) building is via third-party verification. Griffin EnerG has had the opportunity to work on the design and operation of several NZE projects which have been verified by a third party through a certification system. The Living Building Challenge, Green Globes, and the International Living Future Institute’s (ILFI) zero energy certification are relevant work examples illustrated below.

The Department of Energy’s (DOE) zero net energy building (ZNEB) definition is an alternative path to third party certifications. On multiple occasions, we have had the opportunity to provide feasibility studies and post occupancy evaluation for getting projects to ZNE. The projects above illustrate projects which either explored ZNE and chose not to obtain the status, the owner experienced issues getting to ZNE, or required corrective action post occupancy to obtain the operational goal.
