Stretch Codes on the Road to Zero Energy – Potholes and Speed Traps Ahead

Paper / August 27, 2018 / Codes And Policy

This paper details how a range of stretch code efforts, working in parallel, contribute to the overall progress in energy savings, with many current stretch codes targeting 20% energy savings from ASHRAE 90.1-2013/2015 IECC. It also explores how stretch codes trying to go beyond this level of savings face common structural, legal, and technical barriers - and then describes several initiatives that focus on removing these barriers. These include exploring opportunities to address equipment/appliance efficiency where federal preemption prohibits state regulation, and to ensure that many of the process and plug loads not covered by current energy codes can be reduced.
