Building integrated photovoltaic (BIPV) and air source heat pump (ASHP) technologies have emerged as promising solutions for building energy conservation. However, traditional solar buildings face. ••Exhaust ventilation improves PV curtain wall's thermal and. A area, m2c specific heat capacity, J/(kg⋅K)E. The building sector plays a significant role in global energy consumption, accounting for approximately half of the world's electricity usage. Within this, heating, ventilating, and a. Fig. 1 presents the schematic of the EVPV-HP curtain wall, along with a conventional NVPV facade. The curtain wall incorporates semi-transparent Cadmium Telluride (CdTe) PV glazin. To simplify the models' computations, the following assumptions are made:1. Only vertical temperature variation is considered for the curtain wall components, including the inte.
