Abstract

An analytical model has been developed for simulating the semi-transparent photovoltaic double-skin façade (STPV-DSF) system to assess its overall performance. The STPV-DSF integrated building can generate electricity, provide daylight illuminance in its indoor area and lowers the energy demand of a building. During the building design phase, complex simulations are required to estimate the overall performance of the STPV-DSF system. The present study's objective is to provide a reliable and straightforward calculation method for estimating the overall performance of the STPV-DSF system. This paper evaluates the overall performance of STPV-DSF system operating under natural ventilation and forced ventilation for summer and winter seasons of Indian’s composite climate. An experimental investigation has also been carried out on STPV-DSF system to validate the model. A good agreement was observed between measured and calculated temperatures of the STPV-DSF system and solar heat gain to indoor area. For given weather conditions, CO₂ emissions and environmental cost (carbon price and emitted carbon quantity) have also been calculated for STPV-DSF systems by solving energy formulations. The results depicted that STPV-DSF system under forced ventilation exhibited 4.08%, 9.86% and 14.05% higher energy performance than natural ventilation in summer and winter with less CO₂ emissions.

摘要

已经开发了一个分析模型来模拟半透明光伏双层表皮 (STPV-DSF) 系统，以评估其整体性能。STPV-DSF一体化建筑可以发电，在室内提供日光照明，降低建筑的能源需求。在建筑设计阶段，需要复杂的模拟来估计 STPV-DSF 系统的整体性能。本研究的目的是为估计 STPV-DSF 系统的整体性能提供一种可靠和直接的计算方法。本文评估了在自然通风和强制通风下运行的 STPV-DSF 系统在印度复合气候的夏季和冬季的整体性能。还对 STPV-DSF 系统进行了实验研究以验证模型。在 STPV-DSF 系统的测量和计算温度与室内区域的太阳能热增益之间观察到良好的一致性。对于给定的天气条件，CO₂排放和环境成本（碳价格和排放的碳量）也已通过求解能源公式计算出 STPV-DSF 系统。结果表明，强制通风下的STPV-DSF系统在夏季和冬季的CO ₂排放量比自然通风高4.08%、9.86%和14.05% 。
