Though the Department of Energy created the Model Energy Code for contractors and architects, it's a savvy way for do-it-yourselfers to identify the best heating and cooling improvements for their homes. The standard covers doors and windows, insulation, heating and cooling units, and water heaters.

Instructions

Difficulty: Moderately Easy

Step1

Visit the Department of Energy's Web site for specific information tailored to your Zip code. (See energy.gov.)

Step2

Recognize that homes in warm climates need insulation just as much as homes in cold regions. The difference is in the installation.

Step3

Know what type of heating and cooling you use (natural gas, electric, etc.). These are used in figuring the needed R-values for your home.

Step4

Notice that the column on the left of the MEC lists the areas where insulation is used. The middle column tells you what the best R-value is for that area, and the right column tells you the installation method required.
