Following this path, the initial process is very similar to the assumed airtightness option, however air tightness testing is now completed during the as-built phase. By verifying an increased level of airtightness, it is possible to omit some of the other energy efficiency requirements, allowing for a higher level of flexibility. The benefits of an airtight home extend far beyond the compliance stage, resulting in things such as decreased noise levels, better indoor air quality, and increased building durability.
In this option, our team of Registered Energy Advisors evaluates and optimizes each homes envelope design and mechanical performance using energy modeling software. Using this method allows builders to take advantage of current strengths and create their own customized energy efficiency solutions.
