Abstract Recent studies on building envelopes in hot and semi-arid climates have mainly focused on static shading or photovoltaic (PV) combination individually, while the combined impact of real-time shading control and building-integrated PV on net energy performance and peak demand remains inadequately quantified. This research investigated a contemporary single-family dwelling under two warm climates, hot-arid (Najaf) and semi-arid/continental (Tashkent) climates, using EnergyPlus simulations. Five scenarios were analyzed to isolate the effects of static shading, closed-loop internet of things-based control, PV utilization, and their combination. Results showed that closed-loop shading reduces cooling demand by about 16% in Najaf. When combined with PV, net site energy (NSE) decreases by approximately 44% and peak grid import drops from 7.5 to 4.8 kW. In Tashkent, the combined strategy reduces NSE by about 20% and peak demand from 6.0 to 4.9 kW while preserving winter solar gains.
