Seattle Energy Code
Overview

Welcome to the City of Seattle's web site for the Energy Code. This site contains the entire text of the Energy Code in effect in Seattle: the 2006 Seattle Energy Code (2006 Washington State Energy Code plus Seattle amendments). This site also contains links to Client Assistance Memos, forms, and Directors Rules, as well as a search function for the Energy Code.

Energy Code
Energy Code requirements are subdivided by occupancy type. Chapters 1-10 of the Energy Code contain the requirements for Group R occupancy (single family, multi-family, hotel and motel guest rooms, both low-rise and high-rise) and are referred to as the Residential Energy Code. Chapters 11-15 contain the requirements for all other occupancies and are referred to as the Nonresidential Energy Code. Reference Standard (RS) 29 contains requirements that are only applicable to detailed computer analysis.
