Green building & new bldg code

[hotinhawaii]

To jerry, I do not know which climate zone we are in for the purposes of the IECC. My statement I made earlier about windows was partially incorrect. The new code as set to be adopted here requires a SHGC rating for windows that would require either tinting of single glazed windows or double-glazed windows with a low-e coating. Both are more expensive and I know of few people who really want dark tinted windows.

I agree that homes here should be insulated against heat gain particularly in the lower elevations. In my experience, a radiant barrier in the roof structure and sun-facing walls is adequate.
