The main purpose of an energy Power Efficiency Guide Review audit is to help determine which strategies to use in order to save the most energy for the smallest investment. Today, it's time to turn your attention to the building envelope, otherwise known as the stuff that separates the inside from the outside: walls, ceilings, roofs, floors, doors and windows. This is the one area where you use more energy than any other, 43% on average. Before you start measuring, you should print out the photographs of the outside of your house that you took when you put together your site plan and a copy of your site plan. This will help you keep track of the sizes of walls, doors, windows and other elements.

The first step is to take a peek up into you attic. Most houses are insulated similarly throughout an entire system like the attic, but you will need to verify this. While you are up there, you will also want to note what type of insulation there is, and measure its thickness. The most common types of attic insulation are fiberglass batt, usually pink; blown fiberglass, small bits; and blown cellulose, chemically treated recycled newspaper. However, spray foam insulation and radiant insulation are gaining popularity. You will also want to notice if there are areas where there is a continuous layer of insulation, an area which is not broken up by wood ceiling joists (cavity insulation).

Next you need to calculate the area of each different insulation condition. These areas will probably align with major areas of your house, for instance the attic of the one story addition may have different insulation than that of the two story original house. Refer to your site plan for dimensions. You should also start a chart with these headings: Building Element, Cavity Insulation, Thickness, Continuous Insulation, Thickness, and Area. Under Building Element you will list Ceiling/Attic Type 1, Ceiling/Attic Type 2 and so on. Before you move on to the next step, you must first subtract the area of any skylights from the ceiling/attic areas.

After you have filled in the attic information in your chart, it is time to examine your floors. Are there any floor areas in your house that are above unheated spaces? You may have an addition over an unheated crawl space, a bedroom over a porch, or a bonus room over a garage. Add these spaces, Floor Type 1, Floor Type 2, to your chart and fill in the types of insulation and their thicknesses. For those areas that are above unheated, but enclosed spaces such as garages and crawl spaces, add 50% to the thickness of the insulation. These spaces act a buffer to the outside.
