2019 Code Energy Design Rating Fact Sheet

Home / Tech Tip / 2019 Code Energy Design Rating Fact Sheet

The 2019 residential energy code (2019-Code) will use a new energy efficiency metric to gauge code compliance: the Energy Design Rating (EDR) will replace compliance percent for low-rise multifamily buildings. Each metric accomplishes a similar task – determining if a proposed-building uses less energy than a prescriptive-building of the same size and in the same climate zone. The difference between compliance percent and EDR is simply the mathematical construct used behind the scenes in the modeling software and the inclusion of all energy end uses within EDR. CMFNH participants may be familiar with the EDR already as it’s being used for low-rise program compliance with the 2016-Code program.
