Summary of Research
Research and development of renewable energy applications is one of our strategic areas in the Department and the University. The research activities in the Renewable Energy Research Group (RERG) are very robust and diversified, including main renewable energy applications, nanomaterials for solar energy applications, energy saving of buildings, energy transportation, and diversified energy and storage technologies. The research activities of renewable energy applications in buildings include research and consultancy in building-integrated photovoltaic applications (BIPV), wind power generation, hybrid solar-wind power, solar thermal application, solar cooling technology, ground-source heat pumps, landfill gas application and other renewable energy applications in buildings. The research activities of energy transportation are mainly focused on the transportation-building integrations and interactions, including renewable energy supported hybrid zero-emission building-vehicle systems, as well as ocean energy supported zero-emission water transportation system. The research activities in nanomaterials consists of development of self-cleaning coatings and insulation coatings for applications in buildings. The research activities of diversified energy and storage technologies include the centralized and distributed renewable energy technologies, such as solar, wind, hydro, and ocean energy. The energy storage technologies cover both short-term and long-term thermal and electric storages in our research group.
We have a team of renewable energy R&D specialists in system simulation, system design, development of innovative products and control devices, and project monitoring. We have completed many high-profile research and consultancy projects in Hong Kong, Macao and Guangdong (the Greater Bay Area) through donations and collaborations. We are looking forward to your collaborations and supports.

Supporting Facilities
In order to serve the renewable energy industry and investigate various renewable energy applications, the Renewable Energy Laboratory has been developed for teaching, research and consultancy activities. The Laboratory includes a solar simulator lab and a nano-coating development lab, which provides test facilities for testing and developing solar cells, nano coatings and solar energy devices of solar thermal and solar photovoltaic applications. The facilities can be used to develop and verify computer simulation models for use in energy simulation of buildings. The performance of air-conditioning and ventilation systems can also be tested, e.g. natural ventilation, shading effect and passive solar design of buildings. The performance of a lot of industrial products can be assessed so that a certifying program can be developed to issue standard certifications to local industry. Solar collectors, solar cells, photovoltaic panels, advanced windows, facade claddings, heat storage systems, roof materials, etc. can be tested in the laboratory.
