Energy-efficiency features include basics such as a high-efficiency furnace and air conditioner, duct leakage testing, and well-insulated windows (U-value less than 0.35). Many consumers are familiar with the idea that various types of window glazing (double-paned, low-e), sometimes marketed as ‘thermal pane’, are preferred. However, many aren’t aware that the window frame itself can have a strong impact on the window’s overall insulating value - acheiving U-values in the less 0.35 range typically requires careful frame selection - standard aluminum frames popular on ‘luxury’ projects just won’t cut it.

This project also is seeking to use FSC certified wood for all floor and roof framing. There’s a debate raging in the green building community about whether other certification systems should be accepted in lieu of FSC, but the more I learn on this topic the more I am convinced that FSC is the only currently acceptable system. Start here for a good (albeit one-sided) jumping-off point to learn more. My advice: with sufficient volume, you should be able to include FSC products in your project, but give yourself plenty of time to find them.

Finally, this project includes the full range of low-flow plumbing fixtures, including low-flush toilets, which unfortunately remain unpopular even on green for-sale projects (because of performance concerns?). Outside, there’s a rain garden in the rear, and rain barrels collect rainwater for irrigation. Other project team members include construction managers DENCO, MEP consultant JB Engineering Services, and civil engineer Enthalpy Engineering.
