This week on IAQ Radio we welcome Joe Nagan of Home Building Technology Services of Kauhauna, Wisconsin. Since 1985 Joe has been involved in residential building science research in both the US and Canada and has been very active in State wide conservation efforts in Wisconsin. Working with the Wisconsin Energy Conservation Corporation of Madison, he helped co-author the nationally recognized Wisconsin ENERGY STAR® Homes program where he served as Technical Director. This program certified 16,502 homes during its 11 year run. In addition to involvement with Energy Star Homes he worked with the administrator of the Statewide Focus On Energy® programs to co-author a new construction program, known as "Focus on Energy New Homes", which was launched in January 2011 and is currently in effect having now certified over 25,000 new homes collectively.

Mr. Nagan is the go to guy when it comes to residential building science in Wisconsin. He has been involved in the energy efficiency and building trades since the early days of the first energy crisis and continues to be recognized as a leader in the world of building science. Join us today and LEARN MORE about how things have changed over the years, what works, what doesn't and where we go from here on IAQ Radio!
