Energy Code - Forms
Residential Buildings
Includes single-family, duplex, and townhouse, plus 1, 2, or 3-story multifamily buildings whose dwelling units are all accessed from exterior walkways. (All multifamily buildings whose units are accessed from interior corridors are now considered “commercial buildings.”)
You must submit the duct leakage and heating sizing forms, plus the Total UA Alternative form if you are using that path. The Insulation Certificate must be posted in the completed building. These forms and related information, from WSU, are available on the WSU Energy Code website.
Prescriptive Method. This approach is the simplest method of WSEC code compliance. A project complies with building envelope requirements if it meets all minimum insulation levels required for the applicable climate zone. The WSU Energy Program instruction sheet provides a method for documenting compliance with the prescriptive standards.
Glazing Schedule: Using the Prescriptive Method, all glazing must have an "area weighted average" U-Factor of 0.30. This means that some windows can have a higher U-factor than 0.30 and some can have a lower U-factor than 0.30, as long as the area weighted average is U-0.30 or lower. You may need to complete this form to document glazing compliance when applying for your building permit.
Heating System Sizing Calculator: We recommend you use the HVAC sizing tool based on Manual J from Better Built NW. This calculator assumes that your glazing products have an area weighted average of U-0.30. Choose insulation levels and enter the areas of each building component. Hover your cursor over the red triangles to see the embedded help notes. An instruction sheet is also provided.
Total UA Alternative Worksheet (found in WSU's Code Compliance Calculator - Set code compliance pathway to "Total UA Alternative" ): The Total UA Alternative worksheet has been updated to provide the user with error prompts when information is incorrect or missing.
Alterations: Requirements for alterations or remodels of existing structures differ from the requirements for new construction. No credits from Table 406.2 are required and existing buildings are not necessarily required to meet all of the requirements of the energy code. This worksheet will show what is required for your remodel and may be filled out using Excel or by hand.
Commercial Buildings
Includes all buildings except single-family, duplex, townhouse, and 1 – 3-story multifamily that have exterior entries to all dwelling units.
