Trivia Time: What percentage of homes constructed in 2010 received an energy star label? 5%, 10%, 25%, 50%
If you guessed (or knew it was) 25%, then you're in the money, green money that is.
In states like Arizona, Ohio, Nevada and Iowa, the numbers are 50%.
As of January 1, 2013, the state of Illinois will change over to the 2012 IECC which is almost as stringent as the latest version of Energy Star. So, for those single-family residential builders and developers already constructing Energy Star qualifying homes, they will little change to fulfill this new requirement. Yesterday Corbett Lunsford, Green Dream Group, presented an overview of Energy Star version 3 and the 2012 IECC. I encourage you to check out their site.
The Alliance for Environmental Sustainability (AES) has created a great matrix that outlines the major items of 2012 IECC to Energy Star version 3 as well as LEED for Homes, 2009 IECC and Passive House. So, if this is not making sense or is brand new, you have a starting point.
If you are wondering why should I bother with this new requirement and is it worth it?
There are five major reasons: Comfort, Control, Efficiency, Value and Ease of Adoption. These five topics will be covered in detail over the next five days, but to provide a sneak peek, think about how much more your automobile is today than it was 20 years ago. Houses are finally headed in the same direction.
