Building Codes

Built Green is excited to share its recent study, the largest of its kind. The study compared actual electricity use in homes certified by Built Green and non-certified homes. The results revealed that in some cases, Built Green homes were twice as efficient as predicted!

Today, during the Communities and Affordable Housing Unit at the annual Greenbuild Conference and Expo, GBCI announced its adoption of the RELi standard.

Despite  being the perfect application of cladding, weather-resistant barrier (WRB), foam sheathing, air barriers, studs and so forth, the perfect wall is not necessarily the most practical or preferred solution for every building project.

 Residential builds in Oregon are now required to have rain screens, in addition to a water-resistive barrier, with the state’s unprecedented adoption of the 2014 Oregon State Residential Specialty Code Section R703.1. 

Our Appendix-X standard was developed through industry consensus and has been widely adopted by building officials, architects, and builders across the country.

The energy code fundamentally improves the durability of buildings as well as the health and safety of us humans inside. It’s not just a “nice-to-have.”

Tthe American Institute of Architects (AIA) has urged policymakers to reject any weakening of the building codes that have made America’s buildings the envy of the world and called for making public buildings a part of infrastructure renewal.

One analytical tool that can help you consistently determine code compliance and reliable performance is the freely available wall calculator developed by the Applied Building Technology Group (ABTG). 

The U.S. Department of Energy estimates that model energy codes for residential and commercial buildings are projected to save (from 2010-2040) $126 billion at today’s energy prices.

An mpg-like rating for homes is here. For the first time in history, people can find out the expected energy use of any home in the U.S.
