Builders enlist help from energy raters and performance consultants to create the most energy-efficient house plans. This process starts with the framing, by looking for gaps and holes which occur due to wood not being uniform.

In phase two, they check insulation to ensure there is enough and that all the walls and the attic are properly covered.

In the final phase, devices are used to perform a multitude of tests to measure the energy efficiency of the house before the homeowner closes on their new home. Many energy-efficiency problems can be fixed by the builder before the closing date.
