Performance evaluation of PV ventilated glazing

This paper reports the simulation approach and prediction of annual energy performance of PV ventilated glazing systems with daylight saving as applying to typical office environment. Our computer model was developed via the ESP-r simulation platform in association with the RADIANCE lighting software. The new attempt of using indirect interaction between the two simulation programs through daylight coefficient, together with the coupled air-flow network and energy balance technique, has been proved very useful in tackling this kind of long period analysis. The simulation results show that for the range of climate regions from tropical to temperate, the PV natural-ventilated glazing system has advantages over the absorptive natural-ventilated glazing option as well as the single-pane glazing systems.
