Isaacson Residence, Tubac, Arizona 2009
Situated in the heart of the Tumacacori valley in Tubac Arizona, the Isaacson residence is a climate responsive, passive and active solar, and energy efficient single family dwelling. Although its indoor living space is only 2,478 ft², the dwelling is designed to have a series of outdoor living terraces, almost the same size as the house itself. These terraces positively integrate the building with its pristine surroundings. The design concept of these outdoor living spaces was informed by the fact that the climate in Tubac is characterized by a very hot and dry summer season with a large temperature swing (av. 26 °F) due to clear sky conditions. Therefore summer outdoors are pleasant at night. Winters are mild (av. 58.1 °F) but the large diurnal temperature swing can cause few harsh cold winter nights. As a result, with careful design, more than half of the year could be spent outdoors where activities such as cooking, dining and even shower facilities are provided in the design.
