Abstract: A system and methods for photovoltaic phase change material assisted thermoelectric air cooling and heating of a building includes a photovoltaic phase change material wall unit which is cooled by absorption of heat by a phase change material attached to the photovoltaic wall unit; a photovoltaic phase change material roof unit which converts solar radiation into electric energy; Peltier based thermoelectric units configured to heat and cool air streams passing through an air duct; and Seebeck effect based thermoelectric units which convert a temperature gradient into thermoelectric power. A hot air stream in the air duct is directed to an air duct on a roof of the building and a cold air stream from the first air duct is circulated into the building interior to achieve thermal comfort.
