SummaryThe solar skin combines two contemporary building concepts; the use of double façades in renovation projects, and building integrated photovoltaics (BIPV). The double façade is effectively a glass wall attached to the outside of the existing building envelope, separated by an air gap of 0,8 m. Thermal performance is similar to a glazed atrium; the cavity creates a buffer zone which reduces heat loss from the main façade, while harnessing winter solar gains to reduce the building heating load. The cavity can be cooled during summer through ports at the top and bottom of the secondary skin which induce stack-effect ventilation. The PV cells are encapsulated in clear glass modules, which in turn are installed in the outer wall. The semi-transparent modules enable natural lighting to be taken advantage of, while the air gap between the two skins ensures that the modules are well ventilated to maximize their efficiency.
