Inspired by the villas of the Italian countryside, this traditional Tuscan home is powered by the latest in high-efficiency building techniques and systems. A Super-insulated envelope steeped in traditional detail gently moderates the interior temperature while reducing the home's heating and cooling demands. These demands are easily met by high-efficiency building systems that are scaled down to meet the reduced "active" needs. A tankless water heater with a recirculating pump instantly provides hot water to every room, a comfort and convenience that also saves energy and water.
