Performance evaluation of the photovoltaic double-skin facade

The mathematic models for thermal, and PV solar power inserted in the ESP-r, which is the integrating building energy and environment simulation tool, were verified with the measured da ta. Using the verified model, the energy performance of an office building, equipped toward the south with conventional absorptive single facade or un-ventilated double PV facade or outward ventilated double PV facade installation, located at Shanghai was simulated. From the simulation result, the conclusions about annual electricity output generated by the semi-transparent solar cell attached on the south window, impacts of chimney effect on cooling load and heating load, and the optimal operation approach for outward ventilated double PV facade were presented.
