The structure has a 60/40 ratio of walls to windows, a figure that was achieved through computer modeling. "This ratio balances the amount of high R-value solid wall to glazing to create an overall building envelope for optimum thermal performance," Tedesco says. "This ratio was fine-tuned and tested using computer modeling that incorporated site-specific information such as building orientation, and the surrounding infrastructure such as neighboring houses and trees. The end result was an envelope design and window placement strategy that optimizes seasonal daylight cycles, maximizes solar gains in the winter, increases the level of interior natural daylighting, and considers views of the surrounding neighborhood." Because the residents are sensitive to noise, the walls feature extra insulaton, especially in the bedrooms and media rooms.  Photo 8 of 11 in Smart Tech Makes this Modern Home Ultra Energy Efficient
