When designing a wood-framed floor system for residential projects, building to meet the applicable codes is only one step in the design process.
Changes completed on 2015 IECC provisions
Mechanical equipment tradeoffs and additional solar-ready roofs were defeated in a vote.
The 2015 International Energy Conservation Code (IECC)—the code that serves as the model for states’ codes—has undergone final changes. Reinstating mechanical equipment tradeoffs, one of this year’s highly controversial proposals, was defeated, and a measure requiring builders to dedicate roof space and install chase wiring to ensure that all new homes are “solar-ready” fell short of passage by one vote. The code is updated every three years, but states are just beginning to adopt the 2012 version. The 2015 version is not likely to be published until 2014.
