Many homes in Washington are still designed using the standard prescriptive insulation package, which often requires continuous exterior R-5 insulation. While this approach satisfies code requirements, it can also add significant material and labor costs.
The approved C3 Total UA Calculator offers an alternative compliance path by evaluating the overall thermal performance of the building envelope. In many cases, this allows builders to meet Washington State Energy Code requirements without installing continuous exterior insulation.
The result is a simpler wall assembly, lower construction costs, and a fully code-compliant design. Depending on the project, builders can save thousands of dollars while maintaining the same level of energy performance required by code.
The C3 Total UA Calculator is an approved Washington State Energy Code compliance method that evaluates the overall thermal performance of a home’s building envelope. It often provides greater design flexibility than the standard prescriptive approach.
Every project is different, but many homes can reduce or eliminate continuous exterior insulation, resulting in material and labor savings that can total thousands of dollars.
