Draft 2012 Seattle Energy Code
This Draft Seattle Energy Code is still subject to administrative review. Content will be finalized in June and the 2012 Seattle construction codes are scheduled to become mandatory on October 13, 2013.
2012 Seattle Energy Code Development
Washington State has amended the 2012 IECC (International Energy Conservation Code). With each new edition of the energy code, Seattle enacts additional rules to reduce the amount of energy consumed by non-residential buildings. A limited set of new Seattle amendments will be proposed for the 2012 Seattle code, based on the 2012 IECC.
The 2012 Seattle Energy Code draft amendments are for commercial buildings. (Single-family homes and multi-family buildings below four stories will not be impacted by the 2012 updates.) The draft amendments will be discussed in a series of January meetings. These meetings will typically be two and a half hours long. Each one will focus on a limited set of topics, as outlined below.
- Jan 4 – Legislated energy targets, existing Seattle amendments, solar-ready roofs
- Jan 10 – Target performance code option, metering, plug load controls
- Jan 14 – Substantial alterations, allowable glazing area
- Jan 18 – Commissioning report, retro-commissioning
- Jan 24 – Review of changes & additional issues
All meetings will be held in Room 4050 of the Seattle Municipal Tower, from 2:00 to 4:30.
The current schedule calls for the 2012 Seattle Energy Code to become mandatory for permit applications filed after October 13, 2013. It will be an amended version of the new state energy code, which has changed a great deal from previous editions.
City of Seattle policies mandate significant short and long-term reductions in building energy use, far beyond what can be achieved with thicker insulation or better light bulbs. Opportunities for large-scale energy reductions exist in the design process, solar energy, commissioning, plug loads, building operations and major remodeling projects, and each of these is addressed in the proposed amendments. Several amendments facilitate more efficient operations of existing and newly-constructed buildings, while others provide additional design flexibility.
Materials for each meeting will be posted here the week prior to the meetin. Interested individuals may contact EnergyCode@Seattle.gov to be added to the Seattle Energy Code email list.
2009 Seattle Energy Code
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 2009 Seattle Energy Code (2009 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 requirements vary based on whether the space use is defined in Chapter 2 as single-family residential, multifamily residential, or nonresidential.
- Chapters 1-10 of the Energy Code are referred to as the Single-Family Residential Energy Code and contain the requirements for all spaces within the scope of Section 101.2 of the Seattle Residential Code (such as single-family, duplexes, and certain attached townhouses).
- Chapters 11-16 are referred to as the Nonresidential and Multifamily Residential Energy Code.
- Multifamily residential is defined as all Group R occupancy spaces (such as dwelling units, hotel/motel guest rooms, dormitories) not included within the scope of Section 101.2 of the Seattle Residential Code and sleeping areas in Group I occupancy (such as assisted living facilities, nursing rooms, patient rooms in hospitals, prisons, and fire stations).
- Nonresidential includes all other spaces.
- Reference Standard (RS) 29 contains requirements that are only applicable to detailed computer analysis.

Client Assistance Memos
The Seattle Department of Planning and Development produces Client Assistant Memos (CAMs) to provide guidance to users on the intent of the Code and how to comply with its requirements.
As part of the permit application, the Seattle Department of Planning and Development requires that certain forms be submitted to document compliance calculations.
- Single-Family Residential Energy Code forms
- Nonresidential & Multifamily Residential Energy Code forms
- Complete list of DPD forms (non-energy forms)
Director's Rules (DRs) are technical interpretations of code requirements that have been issued by the Seattle Department of Planning and Development. These Director's Rules apply to projects within the Seattle City limits.
