A homeowner is adding a 3-season room and will install a gas or electric fireplace to take the chill off. They will not heat the room full time. Do they need to meet the Energy Code?

Residential, Addition

Yes, they would need to meet the Energy Code since they are installing a fossil fuel or electric heating source. They would need to meet the prescriptive requirements of Table R402.1.2 or R402.1.4 or use REScheck and perhaps take advantage of some tradeoffs across envelope assemblies. Although they would need to do air sealing regardless, the NY Dept. of State has released a technical bulletin that gives some leeway for blower door testing. If the addition is difficult to isolate from the rest of the house, it is not mandatory that one is performed. However, they would still use the air sealing checklist to inspect for air barrier compliance.
