Envelope

Measure Description

This measure proposes two alternatives to improve building thermal envelope and reduced HVAC distribution losses in residential buildings:

  1. High Performance Attics (HPA) minimizes temperature difference between attic space and conditioned air being transported through ductwork in the attic.
  2. Ducts in Conditioned Space (DCS) locates ducts and air handlers in the building’s thermal and air barrier envelope.

Stakeholder Meeting

Several stakeholder meetings and CEC staff workshops were held regarding the Residential Ducts in Conditioned Space/High Performance Attics building energy efficiency topic. The list of past meetings and hearings can be found here.
