Low-E, argon filled windows help keep the interior from overheating in the summer and warm during the winter. The ring-like space that embraces the building on the north side grants constant ventilation and natural light to the living areas. To further optimize the thermal efficiency of the shell and natural sun shading, deciduous trees have been planted at the south-west area of the building.
The bedrooms of the home are set on the second level, facing a garden enclosed by the building and the perimeter wall. With floor-to-ceiling windows, the line between the indoors and outdoors is blurred, and a space that would otherwise be interpreted as compact freely opens and extends to the garden.
Skylights from the floor above pour additional light into the interior, and geothermal energy is used to power the home. Moreover, white cladding on the perimeter wall and the white gravel set at the pavilion level above the lower volume reflects sunlight coming from the south, further cooling the interior.
