Our clients for this project intend for this to be their last residence, and want to benefit from the health aspects of hempcrete as it relates to the prevention of mold and mildew issues in the home, for themselves, their family and many friends. The program for this home includes considerations for outdoor gathering spaces for large events to host community members, policy makers, county and state administrators and building industry leaders in a fun and informative setting.
Hale Mana o’Lana, which translates to “house of hope,” is an off-grid home. The cost of electricity on the Hawaiian archipelago is about 400% higher than on the mainland, so the cost-benefit of photovoltaics in this environment is clear. Local code requires that the hot water system be solar thermal. While the climate considerations here do not include the temperature differences we are accustomed to, the work to achieve a proper balance between the design of the house and its energy requirements is very similar to projects in more extreme climates.
The home is located at 1200 feet elevation on the west side of Haleakala, overlooking the central valley and with views to Kahului and Maalaea Bays; a unique and stunningly beautiful location.
The main living area of the home is on the upper level with an expansive deck that overlooks the valley and bays. The entrance, kitchen and master bedroom on the mountain side have viewing connections to Haleakala- at least on days when it is not enshrouded by clouds. Access and egress on the upper level is of universal design for aging-in-place and wheelchair accessibility. The central living area is passively ventilated by mountain and bayside dormers in the vaulted timber ceiling to take advantage of the prevailing Northwest winds.
While not part of the initial scope of our work, the local requirements are that at least 50% of the five acre site be put into productive agriculture use. The island of Maui has an incredible range of microclimates, with wide variations in wind speed and direction, and rainfall ranging from 10 inches to almost 400 inches annually. This home is located in a relatively dry area of the island, making water conservation strategies of greater importance, especially considering the agricultural component.
