Here in western Colorado, local jurisdictions are busily adopting the 2015 building code.  The 2015 IECC adoptions are the most contentious and most heavily modified.  It is hard to keep track what needs to be done to comply with the energy requirements for residential construction.  Below is a cheat sheet table of adoptions and modifications in Western Colorado.  If you need assistance getting the most sustainable home or just figuring out what a jurisdiction wants – give Confluence Architecture a call.  How is the 2015 IECC different than 2009?  See this blog.
