Off-Grid Home #2

The quarter-acre kuleana lot fronts the ocean. The natural terrain is flat and rocky leading to pahoehoe tidepools and small rock formations along the shoreline, with a warm, humid, and calm environment. The typical winds generated are from thermal convection currents, with cool air traveling downhill in the early morning and warm air blowing onshore during the day.

The program includes three bedrooms, one full bath, outdoor shower, utility shed, kitchen, living, dining, and covered lanai. The enclosed living area is 1,460 square feet, with an additional 528 square feet of covered lanai and 1,000 square feet of open wrap-around lanai.

The domestic hot water is heated by solar collecting panels on the roof with a storage tank in a utility shed on generator back-up with a timer switch to minimize unnecessary heating.

The photo-voltaic panels on the roof provide solar energy conversion to a battery array in the utility shed. The home operates at net-zero energy.
