New Commercial Energy Codes In Seattle

April 29, 2002
New commercial building energy codes have gone into effect in Seattle, WA. The new codes exceed national energy efficiency standards by nearly 20%.

Although these changes were made to the equipment requirements for commercial buildings, including hvacr systems, a broader revision of the energy codes for residential buildings will take effect in July. The residential revision will require insulation R-values ranging from 21 in the walls to 38 in the ceilings, as well as other changes.
