SYSTEMS: A small water tank is located inside for the sink and coffee machine. The construction focused on cutting down heat gain by using concepts such as triple-paned windows that include argon 90 gas and walls insulated with vacumn sealed insulation. Das Haus uses a heat recovery system that cuts down on the amount of energy used by capturing the energy from interior air as it is exhausted. The pavillin PV array's power is stored in a series of (12) closed-valve lead acid batteries. These batteries feature a gell electrolyte which cuts out the refilling process. There is no maintenance required, very little ventilation, and the batteries can be installed horizontally and vertically.
INTERIORS: Doors, floors, and walls provide 10 times more insulation than those constructed in the U.S. and featured streamlined hardware. Interior materials feature plastic "3-Form" type cabinetry doors, wood flooring, and vinyl wall panels. The majority of the lighting is LED.
