Application of PV Window for Office Building in Hot Summer and Cold Winter Zone of China

Abstract

In this paper, three kinds of PV glazing system applied to office building of Shanghai which located in hot summer and cold winter zone of China were studied. Building simulation software Energy Plus was used to simulate thermal load, lighting electricity consumption, and PV electricity generation. According to the simulation results of annual electricity consumption, taking SC as the comparison basis, the saving rate of single PV glazing system (SPV) was 3.6%, double PV glazing system (DPV) was 4.8%, and natural-ventilated PV glazing system (NVPV) was 6.7%.

Energy performance comparison among see-through amorphous-silicon PV (photovoltaic) glazings and traditional glazings under different architectural conditions in China

“…Li peng [9] conducted a simulation study on a PV window with a fixed architectural assumption, and results showed a better overall performance achieved by PV glazings (includes single and double PV glazings) compared to clear glazings in four different climate zones. Another study [10] showed a similar result with an overall energy savings rate of 3.6% and 4.8% for single and double PV glazings respectively. Studies above indicated the importance of overall energy performance in evaluation of PV glazings, and revealed the great potential of PV glazings and facades in terms of energy saving.…”

“…When the daylight illuminance level is below 300 Lux, the artificial lighting will be activated and reach the required illuminance level, with the extra electricity consumption calculated by Energy Plus. To obtain the daylighting simulation results in Energy Plus, visible transmittance is required, as given in equation (10).…”
