Abstract

With large spaces and high energy consumption, commercial buildings often do not rely on side lighting in their commercial space but achieve adequate lighting through atrium configurations. Therefore, the atrium skylights form changes will greatly impact the corresponding indoor physical environment and energy consumption of commercial buildings. Meanwhile, the applications of building integrated photovoltaic (BIPV) had been steadily increasing. Skylight integrated photovoltaics (SIPVs), owing to their dual benefits of shading and lighting, as well as their capacity to collect and utilize solar energy, have enjoyed increasing popularities. However, their relatively poor thermal properties can pose huge challenges to their effectivenesses for applications in the cold regions (characterized by the severe cold and cold thermal zones of China). Therefore, to ensure the comprehensive energy-saving efficiency of SIPVs in commercial buildings among severe cold and cold regions, this study employed the Designbuilder tool (EnergyPlus engine) to conduct the energy consumption simulations of three typical SIPV forms applied by commercial buildings in relevant climate zones. The results show that, in both climate regions, single-slope SIPVs are more beneficial for PV power generation, although they may not represent the most efficient energy-saving form. In severe cold zones, flat skylights without photovoltaic integration exhibit to be more energy efficient, while in cold regions, SIPV installations become more effective in energy reduction, with the optimal energy-saving performance observed with the flat SIPV form. The research findings can provide key strategic references for SIPV form optimizations among severe cold, cold regions or similar climate zones worldwide.
