The Department of Building Environment and Energy Engineering (BEEE), originally named Building Services Engineering (BSE), was officially established in December 1981, and has become one of the largest BEEE departments worldwide. As a leading provider of trained professionals in building services for the unique environment of Hong Kong, research in BEEE focuses on enhancing the quality of the environment, energy efficiency, the use of renewable energy, and the safety and resilience of buildings to effectively address the contemporary concerns and future challenges of urban environments. Its core mission is to devise and improve engineering systems to promote the health and well-being of building occupants by providing a sanctuary from the elements and the extremes of temperature, noise, light, toxins and pathogens at the lowest cost of energy and resources. It offers a range of undergraduate and postgraduate degree programmes serving the needs of the local industry.


BEEE research is highly recognized among the most prestigious universities worldwide, being ranked 15 in both Architecture & Built Environment and Engineering (Civil and Structural Engineering) by the latest 2022 QS World University Rankings. The expertise of BEEE academic staff spans a wide range of disciplines, including the aspects of sustainability; building energy, heating, ventilation and air-conditioning systems; fire and safety engineering; electrical technology; public health; indoor environmental engineering; architectural engineering; computer-aided design and facilities management.


In recent years, the Department has made a remarkable achievement in securing highly competitive and prestigious multi-year, multimillion-dollar grants, including two from the Theme-based Research Scheme, one from the Research Impact Fund and three from the Collaborative Research Fund.
