The house is designed to face the sun with its triple-pane windows (U = 0.5) during the heating months of the year and turn its highly insulated back (U = 0.12) to the sun during the warmer months when heating isn't necessary. This significantly reduces heating and cooling requirements for the

balcony railings to provide heat and warm water. These innovations along with the favorable insulation of the residence allows the
Heliotrope to capture anywhere between four and six times its energy usage depending on the time of year. The Heliotrope is also fitted with a

is a concept coined by Rolf Disch that indicates a structure's energy efficiency. A PlusEnergy building holds a positive energy balance, generating more energy than it uses. The first

Photovoltaic solar panels with a rated power of 6.6 kW on its roof provide five to six times more energy than the building uses, making the building "energy positive" (
