The concept of U-factors for building enclosure systems has been around for decades but has become more widely recognized as building energy codes (e.g., ASHRAE 90.1) have become increasingly stringent. Prescriptive requirements for insulation in walls and roofs are often difficult to meet in buildings with complex architectural design. Consequently, the U-factor option for compliance has seen much more use in the last few years. This session discusses the basics of heat transfer in buildings as well as the general concept of the U-factor. Examples of how thermal bridging can impact energy performance and U-factors are presented.
