As cities in hot climate regions face escalating challenges from rapid urbanization and climate change,
there is a pressing need for innovative strategies that reduce building energy demands while ensuring occupant
comfort and environmental quality. Semi-transparent photovoltaic (STPV) windows present a promising solution by
enabling on-site renewable energy generation through building façades, without compromising daylight access or
architectural integrity. This study proposes a practical framework for integrating STPV technologies to support urban
sustainability in hot climates, based on a multi-dimensional analysis of energy performance, thermal behaviour, and
visual comfort under intense solar exposure. Critical design and operational challenges—such as overheating, glare,
and dust accumulation—are examined to inform climate-responsive integration strategies. Insights from the
Msheireb Smart City case study in Qatar illustrate how mixed-use developments can leverage STPV technologies to
enhance energy efficiency, align with climate adaptation goals, and maintain cohesive architectural aesthetics.
Findings suggest that STPV systems have the potential to reduce cooling loads by up to 25% and provide on-site
electricity generation that could meet 10–20% of a building’s energy needs, depending on factors such as glazing
type, orientation, and integration method. This study also highlights the potential of STPV to contribute to policy
recommendations on sustainable energy practices in hot climates. By positioning STPV systems at the intersection
of renewable energy innovation and urban climate resilience, this research offers actionable guidance for advancing
sustainability in hot-climate cities through integrated building design, energy strategy, and urban planning.
