Abstract
One thing that can generally be agreed upon is the International Code Council®’s suite of building codes is always changing. The changes occur on a three-year cycle, and some recent changes included updating the International Energy Conservation Code.® Beginning with the 2021 IECC, ICC approved a new requirement that affects roofs. Section C401.3, “Thermal envelope certificate,” requires a thermal envelope certificate be provided at the completion of a building project. The certificate is to be permanently posted on a wall in the space where the building’s HVAC equipment is housed, a utility room or other approved location. An approved location is one that is acceptable to the local code official.
