Million Housing Units

At the same time that the number of housing units was increasing, the size of housing units in the United States also became increasingly larger, resulting in an increased demand for energy-consuming activities, such as heating, airconditioning, and lighting. The percentage of smaller housing units, those with four or fewer rooms (excluding bathrooms), decreased from 35 percent to 30 percent (Figure 2.3). At the other end of the scale, the percentage of larger housing units, those with seven or more rooms, increased from 22 percent in 1978 to 29 percent in 1997.

Energy Consumption

Although the number of housing units in all four U.S. Census regions increased over the 1978-1997 period, the distribution of those same housing units across the Nation also changed (Figure 2.2).

Energy consumption can be expressed as the amount of energy consumed within the housing unit (site energy) or it can include the energy consumed in generating and
