LOW-RISE RESIDENTIAL: With either the prescriptive or performance compliance paths, there are mandatory measures that must always be installed. Many of the mandatory measures deal with infiltration control and lighting; others require minimum insulation levels and equipment

efficiency. New for the 2016 Building Energy Efficiency Standards are mandatory measures that require higher insulation values for the building envelope, better duct sealing to limit air leakage, and high-efficacy lighting. For detailed information on these changes, see applicable sections within this manual. The minimum mandatory levels are sometimes superseded by more stringent prescriptive or performance approach requirements. For example, if mandatory measures specify R-22 ceiling insulation and the prescriptive approach, Package A, is used, then R-38 ceiling insulation (depending on climate zone) must be installed. Conversely, the mandatory measures may be of a higher efficiency than permitted under the performance approach; in these instances, the higher mandatory levels must be installed. For example, a building may comply using the performance computer modeling only R-7 insulation in a raised floor, but R-19 must be installed because that is the mandatory minimum.
