Applying Building-Integrated Photovoltaics (“BIPV”) System at Bauhinia Hotel (Central)


During the Reporting Year, the Bauhinia Hotel/ Serviced Apartment (Central) underwent a major renovation and is scheduled to reopen by the end of 2024. Notably, the renovation project incorporated the innovative use of Building-Integrated Photovoltaic (BIPV) technology, integrating photovoltaic modules into the building envelope, including the roof and the façade.

This renovation project stands out as a pioneering initiative, being the first building in Hong Kong to adopt full envelope BIPV systems. These systems serve the dual purpose of functioning as the building envelope while also generating power. They not only generate solar power that can be seamlessly connected to the grid but also offer enhanced aesthetical flexibility. By blending harmoniously with the surrounding building envelope, they overcome the physical limitations of conventional PV modules.

Although the cost of BIPV façade systems for Bauhinia (Central) is 10-15% higher than that of conventional curtain wall systems, their implementation will result in the generation of approximately 24,000 kWh of electricity and an annual reduction of over 17 tonnes of carbon emissions upon completion. This upgrade has earned us the Green Council UNSDG Achievement Awards Hong Kong 2023 –Project Award.
