The building's air-ventilation system is natural. Fresh air is channeled under the building by a flow induced by temperature differences between the outside environs and the inside of the building, entering through ducts in the floor and leaving the building through vents on the roof.

All energy used in the building originates from environmentally sustainable sources. Solar and hydro power supply the building with electricity in addition to a unique generator that produces electricity from the temperature difference existing between hot and cold water. The house is heated using geothermal hot water from Sólheimar's own borehole. Future plans include the installation of a windmill.
