Multi-Criteria Performance Assessment for Semi-Transparent Photovoltaic Windows in Different Climate Contexts

Semi-transparent photovoltaic (STPV) windows, one of the building façade elements, can generate electricity and provide a certain amount daylight for occupants. Nevertheless, expensive cost unsatisfying indoor performance in room are common problems with STPV windows. This study investigates thermal, daylight, energy, life-cycle windows by considering varied window-to-wall ratios, orientations, module types. The balance index (elBI) indicator is proposed as evaluation criteria. Two types models established this study: rig-test baseline model KAIST campus research facility test along actual measurements simulations using DesignBuilder. Results show that window Mediterranean climate demonstrates higher efficiency based on elBI indicator.

Furthermore, lighting energy consumption becomes critical variable type selection, while simple ON/OFF control system improve value 0.02 ~ 0.04. Our findings could potentially decision-making urban systems selection different
