BIPV / BAPV

Company Experience and Expertise in Solar BIPV / BAPV Systems

Energreen Technologies Pte. Ltd. is a Singapore-based renewable energy solutions provider with demonstrated expertise in Building-Integrated Photovoltaic (BIPV) and Building-Applied Photovoltaic (BAPV) systems, particularly in complex urban and high-rise environments.

Energreen has successfully delivered Singapore’s first HDB Vertical Solar Pilot Project at Yuhua (JE21), a landmark BAPV façade installation under the national SolarNova programme. The project was completed in full compliance with regulatory, safety, and performance requirements, achieving the Certificate of Conformity (COC), Declaration of Conformity (DOC), Fire Certificate, and Certificate of Statutory Completion (CSC) from the relevant authorities. This milestone project demonstrated the technical feasibility, structural integrity, fire safety compliance, and long-term operational viability of vertical solar façade systems on public residential buildings in Singapore.

Building on this national achievement, Energreen continues to advance the deployment of vertical solar technologies across public and private developments. The company actively collaborates with government agencies, statutory boards, and industry partners under the SolarNova programme to support Singapore’s transition toward net-zero energy buildings, enhance renewable energy adoption in dense urban settings, and contribute to the development of resilient and sustainable urban infrastructure.

 

Energreen’s proven track record, regulatory familiarity, and integrated design–build capabilities position the company as a reliable partner for BIPV and BAPV projects requiring high standards of engineering, compliance, and execution.

Vertical Solar Facade Photovoltaic

With the rapid changes in solar technology, solar panels are increasingly integrated into the overall design of building facades / cladding, what look like ordinary skyscrapers of the future may actually be energy-efficient zero-carbon buildings filled with glass solar panels. In addition, air conditioning and electricity costs are significantly reduced. Further evaluation analyses the potential of future ecological buildings, which can be upgraded to independent local photovoltaic power plants.

Wall Mounted Solar Photovoltaic System (Facade / Cladding Application) – BIPV & BIPV

More and more high-rise buildings have been installed with Solar facades / cladding Photovoltaic System or Curtain Wall Photovoltaic System to generate free and clean energy and injected into the grid. As these BIPV modules that are installed onto the façade are not only a visible sign of environmental protection and sustainability, but also a key component for achieving nearly zero or surplus energy. One of the facades would be widely exposed to the sun at a time and interacts with the movement of the sun. Besides the BIPV generating solar power, the BIPV modules also acts as a thermal insulation, sound reduction and protection against the weather. With the ntegrating of the Photovoltaic into the Building envelope / cladding, this will improve the energy-efficiency with the building by reducing the air-condition and mechanical ventilation. This results in the reduce of GHG emissions.
