The house was heated by a system designed so that Glauber's salt (a form of sodium sulfate) was allowed to melt in a solar-heated space. During the day, fans brought air through the warm space and via ducts out to the rooms of the house, at night air was brought through the same space where the salt then cooled and released its stored heat.

This strategy allows the house to gain its needed southern exposure for the solar array while also connecting the living area with the back garden space. The result is a contrasting expression with the entry facade of the solar array facing one street, and the more quiet and modest original structure facing the other street.
Perovskite solar cell technology can be tuned to red, green and blue by changing the metallic nanowire thickness to 8, 20 and 45 nm respectively. [19] Maximum power efficiencies of 10.12%, 8.17% and 7.72% were achieved by matching glass reflectance to the wavelength that the specific cell is designed to most optimally transmit.
Student-built houses powered exclusively by solar power on display in Washington D.C. at the Solar Decathlon 2009. The U.S. Department of Energy (DOE) Solar Decathlon is a collegiate competition, comprising 10 contests, that challenges student teams to design and build highly efficient and innovative buildings powered by renewable energy. The ...
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.
Sloan then built a number of passive solar houses, and his publicity efforts contributed to a significant "solar house" movement in the 1940s. [8] Frank Lloyd Wright used passive solar principles in some of his designs, most notably in the Jacobs House, built in 1944 in Wisconsin, which was also known as the "Solar Hemicycle" or "Solar Hemicyclo."
