Residential buildings account for about 21% of total energy consumption in the United States, and windows alone are responsible for 25%–30% of residential heating and cooling energy use. The U.S. Department of Energy estimates that upgrading the nation’s current window stock to meet DOE’s long-term performance goals could save more than 2 quadrillion Btu. Clearly, expanding the use of energy-efficient windows should be of interest to engineers and others interested in reducing energy consumption.
This 4 hour course presents guidelines to help architects, engineers, builders, homeowners, and designers select energy-efficient windows in new and existing residential construction in all U.S. climate zones. It includes information about window products, attributes, and performance. It provides cost/benefit information about window energy-savings and about non-energy benefits such as thermal comfort and reduced heating, ventilation, and air conditioning demands. The guidelines also provide information about the energy impacts of design decisions such as window orientation, total glazing area, shading conditions, and about proper window installation.
