Efficient Heating and Cooling
For almost all buildings, heating and cooling are key challenges. The techniques or systems used for heating and cooling are numerous and varied. Different climates require different approaches — ranging from simple ventilation to complex machinery like furnaces, boilers, heat pumps, air conditioners, evaporative coolers, humidifiers, dehumidifiers, chillers and cooling towers. The optimal use of the right combination (and right size) of heating and cooling systems can dramatically affect energy use in the home or business.

The Western Area Power Administration has produced the following fact sheets on heating and cooling topics, available as Adobe Acrobat PDFs. Download Adobe Reader.
The U.S. Environmental Protection Agency (EPA) and DOE collaborate on the Energy Star program, a voluntary labeling program designed to identify and promote energy-efficient products to reduce greenhouse gas emissions. The Energy Star Web site provides useful information on thousands of these products, including heating and cooling equipment.
DOE's Consumer's Guide has a very in-depth section on space heating and cooling.
