Description

Research activities previously performed on shorter simulation timeframe had shown that building-integrated photovoltaic/thermal double-skin façade (BIPV/T-DSF) could maintain a comfort temperature within a building, by adopting a fan-assisted ventilated air cavity in summer, and a non-ventilated air cavity during winter in order to reduce overheating phenomena in the air cavity and consequently in the building.

In this paper, a naturally-ventilated BIPV/T-DSF commercial type of building was studied using TRNSYS simulation for enhancing the indoor thermal performance. The TRNSYS building model was calibrated by using in-situ experimental results taken from the existing published studies. Comprehensive comparisons among the naturally-ventilated BIPV/T-DSF, single-skin BIPV/T façade and non-ventilated BIPV/T-DSF for whole year period were presented thoroughly in terms of annual energy demand as well as comfort operative temperatures for commercial buildings in Sydney. Comparative analysis showed that the naturally-ventilated BIPV/T-DSF could significantly reduce cooling demand throughout the year and maintain a better operative temperature in summer compared to the single-skin BIPV/T facade, whereas the non-ventilated BIPV/T-DSF could always reduce heating demand as well as maintain a better operative temperature in the relative cold periods.
