Energy analysis of semi-transparent BIPV in Singapore buildings

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

“…The study also demonstrated that a low-E glazing exhibits better energy performance than an a-Si PV glazing. Poh Khai Ng [13] performed an energy analysis of see-through PV glazings in Singapore and revealed the potential to use a-Si seethrough PV glazings in any orientation in tropical locations. This study specifically indicated that optimising the WWR (window-towall ratio) with different design strategies is necessary to achieve the highest energy benefit.…”

Energy saving potential of semi-transparent photovoltaic elements for building integration

“…Simulations were carried out using EnergyPlus and the main finding was that the total building electricity consumption could be reduced by 55% using optimum STPV windows. Khai Ng et al [21 ] used the same simulation tool to examine six commercially available STPV elements. They defined a new index to evaluate the overall energy performance in Singapore and found that BIPV glazing solutions provide an energy savings rate of between 16.7% and 41.3% compared to common window glazing for large facade openings.…”

A study of the potential benefits of semi-transparent photovoltaics in commercial buildings

“…When considering the impact STPV windows have on the building energy performance, it was shown that the selection of the ideal STPV optical properties was independent of the building orientation (Chow et al, 2007;Miyazaki et al, 2005;Robinson and Athienitis, 2009), within this orientation range. Though, Miyazaki et al (2005) and Ng et al (2013) showed, through simulations, that the WWR has an impact on the selection of ideal STPV optical properties.…”
