Performance Optimization of Window Integrated Photovoltaics Systems inTerms of Energy Production, Thermal Comfort, and Daylight Provision for aPrototypical Office Room Using EnergyPlus

Integrated photovoltaic systems (BIPV) play an important role not only by providing electricity but also byimproving thermal comfort and daylight availability through an optimized design solution. Providingsufficient lighting in office spaces is one of the main bases for increasing employees’ satisfaction andproductivity and at the same time, supplemental artificial lighting is one of the major energy consumers inoffice buildings. This article focuses on the optimization of window-integrated photovoltaic (BIPV)systems in terms of energy production, thermal comfort, and daylight provision for a prototypical officeroom. The study utilizes EnergyPlus building energy simulation software to model a prototypical officeroom in a temperate climate ("Cfb", Mannheim with a latitude of ۴۹.۵ degrees, Germany) and arid climate(“BWh”, Sabzevar with a latitude of ۳۶.۱ degrees, Iran) with different Window-IPV configuration. Thethermal and optical properties of both clear and BIPV windows are summarized. The research site chosenfor the study is Manhheim and Sabzevar, to compare them in terms of urban climate and building energyconsumption. The energy production, thermal comfort, and daylight metrics of clear glass and WIPVwindows are simulated under climate conditions. The results demonstrate that BIPV glazing can enhanceenergy generation and daylight levels relative to conventional windows, but may impact thermal comfort.The study provides guidance on optimizing BIPV Windows design to maximize overall performance. Thisresearch delivers valuable insights into harnessing BIPV systems for more sustainable and energy-efficientoffice buildings. Further work is needed to explore additional geographical locations and glazingtechnologies.
