Update: The house is done, see here. I've just put a deposit down in one of those neighborhoods where a single builder is putting up a bunch of houses in one area with about half a dozen floor plans available. At this point I've chosen my lot and floor plan and a few updates, but I'm not committed to anything yet. I've got a week before committing to it, and after that I'll still have some time to change some of my options. Anyways, this is the first time I've ever done this, so I'm feeling a bit overwhelmed at times. The builder is Ashton Woods, and its supposed to be an Energy Star compliant house. I've done a bit of research on both, and haven't found anything bad yet. At least I haven't found an AshtonWoodsSucks.com or EnergyStarSucks.com so far. Most of the stuff in the house so far as I can tell seems good. The walls are insulated with R-13, attic walls and sloped ceilings have R-19, and the flat ceilings (which mine has mostly) are R-30. They also seal all the electrical stuff, lumber wall baseplates and windows. Its got double pane high efficient glass, dual zone AC, a 10 SEER AC, programmable thermostats, and some other niceties. So anybody have suggestions on things I should look for? Anyone ever dealt with this builder? The BBB has no complaints on them in this area that I could find. I'll probably be back with more questions and info as this goes on. As things get more settled I'll be posting a separate HT related thread in the Construction forum. Here's the floor plan if you'd like to take a look.
