Special Issue Information

Dear Colleagues,

The Special Issue of the journal is titled “Building-Integrated Photovoltaic/Thermal Systems for Net Zero Energy/plus Buildings”, and it will mainly be focused on technologies which combine PV and thermal systems, concurrently providing thermal energy and electricity. The concurrent production of heat and electricity increases the total energy generation of PVs per unit surface area in comparison to the standalone PV system. The BIPV/T system can increase electrical performance and lead to faster payback time than traditional PV systems. This Special Issue will focus on BIPV/T systems and their applications, the most recent developments in PV technologies for BIPV/T application, energy and exergy analysis of BIPV/T systems, BIPV/T systems coupled with heat pumps, BIPV/T systems coupled to building mechanical systems, active and passive BIPV/T systems, experimental, analytical and numerical analysis of heat transfer in BIPV/T systems, life cycle cost analysis, and life cycle conversion efficiency. Performance analysis of BIPV/T system, techno-economics and sustainability of BIPV/T system, worldwide case studies, and energy payback periods are all in the scope of this Special Issue.

Hong Kong’s government has recently introduced the feed-in tariff scheme to promote the photovoltaic (PV) system as a promising way to address global warming. The feed-in tariff scheme depends on the type of the PV system and its installed capacity. This study aimed to investigate the techno-economic feasibility of mono-Si and poly-Si PV systems in the rooftop area of a commercial building, Pao Yue-Kong Library of Hong Kong, under the feed-in tariff scheme. The analysis was carried out in two phases: (i) technical analysis of the rooftop PV systems by considering the shading effect and solar radiation and (ii) economic feasibility of the rooftop PV systems under the feed-in tariff scheme from the life cycle perspective. The main findings of the case study can be summarized: (i) the rooftop area of the target building would not be significantly affected by surrounding buildings; (ii) the highest amount of solar radiation was estimated at 136.96 kWh/m2 in October, while the lowest value was 55.64 kWh/m2 in February; (iii) the total amount of module energy yield from the mono-Si PV system was estimated at 917.58 kWh/kW, indicating that it was very similar but a little bit lower (i.e., 0.48%) than that for the poly-Si PV system (i.e., 921.98 kWh/kW); and (iv) payback periods for mono-Si and poly-Si PV systems were estimated at 8.67 and 8.31 years, respectively. The feasibility study can contribute to providing facility managers with a practical guideline to determine the appropriate strategy in implementing the PV systems in buildings under the feed-in tariff scheme.

A novel façade element is presented that forms a symbiosis between an enhanced box-type window, a closed cavity façade, and a Trombe wall. This hybrid, transparent-opaque façade element features an absorbing water tank, that is installed behind a controlled shading device toward the cavity of a non-ventilated Double Skin Façade in the parapet section. To evaluate the potential impact on building performance, a transient simulation model is developed in Modelica and calibrated by comparison with measurements on a prototype. The effect of the absorbing thermal storage on heat transfers under solar radiation is analyzed in comparison to (i) conditions excluding solar radiation and (ii) an empty tank. An evaluation for four European cities demonstrates that the annual heating demand can be reduced by more than 4.2% and cooling demand by at least 6.6% compared to a façade without thermal storage. The effect is explained not only by the increased thermal mass, but also by the effective modulation of solar gains by the controlled absorbing storage. The dampening of heat flow fluctuations and the control of solar gains is a promising means to reduce the installed power of HVAC (heating/ventilating/air conditioning) installations. Full article
