LEED for Homes vs NGBS comparison
I just read an article on BuildingGreen.com (http://www.buildinggreen.com/auth/article.cfm/2010/6/29/NAHB-and-LEED-for-Homes-Equivalent-Except-on-Energy-Says-Report/) about a study the AIA-Cincinnati published comparing LEED for Homes vs NGBS. The results, for the most part were consistent with findings many of us working with both programs have found over the years; however, I would like to know if this same report found that the LEED for Homes green levels are not tied down to a minimum Energy Efficiency or HERS rating. In other words, with the LEED for Homes I can have a Platinum Level house with a HERS 85 or Hers 50, where under the NGBS all green levels are tied down to a minimum HERS rating.
If you were going to talk about cost difference between both programs, it would make a huge difference if you have a Platinum level home with HERS 85 vs HERS 50. That’s way I think the cost comparison is not fair.
As an observation, before the NGBS was to come out and when we were writing the Energy Efficient Building Tax Credit in NM, I was given the opportunity by NAHBR to score several projects I had designed both in the NGBS and LEED for Homes. I found that all of the projects in new subdivisions would score higher in the NGBS, but all infill projects scored higher in the LEED for Homes program. It may have been coincidence, but I would like to know if anyone had different or same opinion.
Any thoughts on this matter? Alex? Allyson? Carl? Ann?
