Please do report back. This is an important consideration for us. When we ask about of our sales rep we get a song and dance. "Don't worry our homes are built to the highest enery efficient standards." Well then, what's the SEER rating of the heat pump? Answer "it's high!" I feel any developer who doesn't brag about energy efficient standards in their marketing liturature probably doesn't follow any. These days energy star ratings are just about standard. But I guess the villages has such a captive market they could sell unheated tents in LSL and they would sell out in a day.
