dc.titleApplication of building-integrated semi-transparent photovoltaics (STPVs) in typical Hong Kong office buildingen_US
dcterms.abstractBuilding integrated photovoltaics (BIPV) is a renewable energy revolution that PV panels can be integrated with building facade to generate electricity. This recent study conducted investigation on two typical semi-transparent photovoltaics (STPVs), including dye-sensitized solar cell (DSSC) and amorphous silicon (a-Si) soar cell, to apply and replace traditional clear glass window in Hong Kong office building which is usually constructed with curtain walls lead to high cooling consumption. Owing to antagonistic relationship between cooling consumption and power generation from the window size of STPVs system, optimal window-to-wall ratio (WWR) should be under consideration. Simulation software Energy Plus was adopted in this research to predict the cooling demand of the buildings and energy output from STPVs was obtained by calculations to explore the appropriate WWR from 10% to 80% on varying orientations. The results showed that optimal WWR of both DSSC and a-Si solar cell is 10% by applying on four orientations of the building, i.e. East, South, West and North. By comparing the energy performance between these two STPVs, energy balance index (EBI) has been utilized and DSSC of 10% WWR achieved the best energy performance. For adopting DSSC or a-Si solar cell on only one orientation, optimal WWR of both STPVs is 10% on each orientation. It was discovered that south-facing DSSC reaches the best energy performance between 10% to 50% WWR and followed by north-facing a-Si solar cell for 60% to 80% WWR when compared to other WWR and directions.en_US
