Solar Concentrators for High-Rise Buildings

Global concern about electrical consumption and environmental sustainability inspired the application of solar energy in buildings. As expected, more than 60% of the world’s population will live in urban areas in 2030. Residential buildings are being built to be increasingly taller. At present, rooftops are typically used to install PV systems, however, as buildings are becoming taller, the available roof space per living unit may not be adequate to meet the energy demand of the building. On the other hand, many high-rise residential buildings have a large façade-to-roof area ratio. Building facades could therefore potentially be used for harvesting solar energy. This project presents a solar facade technology that is necessary to the built environment for electrical generation as well as enhancement of thermal performance within the building area.
