Energy Code - Forms

Residential Buildings

Includes single-family, duplex, and townhouse, plus 1, 2, or 3-story multifamily 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 below.

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. This Excel file provides a method for documenting compliance with the prescriptive standards.

Suggested Option Combinations: This document contains combinations of options from Table 406.2 to achieve 3.5 credits which is the amount needed for an average size house in Washington (1,500 to 5,000 square feet). There are numerous other combinations available but the following utilize readily available equipment and/or some minor upgrades to the building envelope.

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: This calculator - a simpler version of previous worksheets for newly constructed buildings - assumes that your glazing products have an area weighted average of U-0.30. Use the dropdown boxes to choose insulation levels and enter the areas of each building component. The form has embedded instructions; hover your cursor over the red triangles to see the help notes. This calculator sizes heating systems only; it will not accurately size cooling systems.

Total UA Alternative Worksheet (formerly Component Performance): 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 multifamily buildings that are 4 stories and taller, plus all non-residential buildings.
