The recently sold Swire Properties residential project in Hong Kong demonstrates, once again, that renewable energy generation is most effective when integrated into urban environments, where energy is consumed. The building incorporates custom photovoltaic glass into its rooftop, enabling on-site electricity production while preserving the curved design and overall architectural identity of the building.
The photovoltaic solution, supplied by Onyx Solar, was specifically adapted to the building’s structural and curved architectural features. This allows the solar glass to blend naturally into the rooftop, making its energy-generating function almost imperceptible while maintaining visual harmony with the surrounding environment.
Although modest in scale, the project demonstrates how Building Integrated Photovoltaics (BIPV) can extend beyond large landmark developments to residential architecture. By embedding photovoltaic technology into construction materials, buildings can actively generate energy without compromising their design or aesthetic integrity.
The customised photovoltaic glass was tailored to match the building’s curves and rooftop structure, ensuring seamless integration and a discreet visual presence. The project highlights how renewable energy solutions can be incorporated in cities without disrupting the harmony of their built environment.
As urban areas continue pursuing decarbonisation and energy efficiency goals, integrated photovoltaic solutions like this provide a practical pathway to distributed renewable energy generation while supporting architectural creativity and design flexibility.
