Measuring Homes for Energy Assessments

Measuring homes accurately is an important part of an energy assessment. If we get it wrong others will make mistakes that can be costly and can slow the process of weatherizing a home.

Generally measuring the home is one of the first things that we do when we assess a house. It is usually done right after we interview the resident or owner.

For simple homes it can be as easy as going outside and measuring the length of each wall of the house, and then going back inside and measuring the height of the ceiling and the height and width of the windows and doors.

In the next few pages we will walk through the measurements of two houses and the calculation of important values that contractors and analysts use in their work. You can then test your skills with another home to see if you know how to measure a home.
