The material here is primarily for the benefit of the contractors' crews who need to achieve these major, measurable improvements.
Interested homeowners are also invited to look through this information if they want to understand how such extraordinary results are achieved, and when they want to know how to identify contractors that really practice Measured Home Performance.
