Energy in Residential Buildings: A Global Study
The impact of energy use in U.S. residential construction is huge, this sector alone accounts for about 22% of the primary energy use. Within residential buildings, space heating, and water heating are the biggest opportunities for energy savings. The electricity used for lighting, cooling, and refrigeration should be targeted next. Despite the opportunities for energy and financial savings, many homeowners forgo necessary improvements due to initial cost concerns or a simple lack of information. This paper will explore global practices that exist to increase energy efficiency in residential construction and disseminate this information as a beginning of the best practice.
In today’s fast-pace technology-driven society the United States along with many other industrialized countries are producing enormous amount of energy to meet the demands of their rising populations. Figure 1 shows the trends over the past six decades1. According to the U.S. Energy Information Administration (EIA), the United States consumed 101,554 trillion Btu (British Thermal Unit) of energy in 2007; an increase of 1.7 percent from 2006 and 6.7 percent from a decade prior2.

In particular, the residential building sector accounted for 21,619 trillion Btu or 21.3 percent of the total energy consumed that year3. But to gain a better understanding of the distribution of energy consumption within the residential sector, the EIA has broken down the primary energy consumption into three categories: fossil fuels, renewable energies, and electricity. Fossil fuels
