The LivingHome will be filled with all the highest of tech, but will have a low impact on the environment. It will be built with only the most efficient green devices and materials, including a 4-kW solar power system, forced air radiant heating and cooling, ultraefficient LED lighting, power-sipping appliances, and mostly renewable building materials. The result? A house that's 36% more energy efficient than ordinary 4000-square-foot McMansions.
The catch? All this energy hyperefficiency will cost a cool $4 million. Here's a hint for you, green builders: Scale is back to 1000 square feet and it'll use a whole lot less energy.
