Development of 2018 Seattle Energy Code

The public is invited to provide feedback and information on proposed amendments to the Seattle Energy Code by the City of Seattle. 

Agenda
Topic: Envelope and C406 Credits

The following proposals are being considered:

• Require thermal bridging analysis for a few significant building elements – balconies, window frames, etc.
• Reduce allowable fenestration (windows and other glazing) U-values
• Exempt projects involving a change of use with high process loads from building envelope improvements
• Increase the number of C406.1 Additional Efficiency Package Option credits needed to meet energy code requirements to 8 credits (instead of 6)
• Change Table C406.1 Efficiency Package Credits to delete credit for “basic” DOAS (Dedicated Outdoor Air System) in R-2 occupancies.  Eliminate double dipping.
• Delete Table C406.1 credits for fossil fuel-fired equipment
