Best Paper of CUE2020

The Department of Building Environment and EnergyEngineering (BEEE) of The Hong Kong Polytechnic University (PolyU) is pleased to announce that Prof. Yang Hongxing and Dr Cao Sunliang of BEEE and their research students’ paper entitled Peer-to-peer trading optimizations on net-zero energy communities with energy storage of hydrogen and battery vehicles has been awarded as the best paper by CUE2020: Applied Energy Symposium:­ Low carbon cities and urban energy systems. Developing intelligent energy solutions for resilient urban systems is a global and complex challenge which involves interdisciplinary fields. With this as theme of the conference, CUE2020 aimed to provide a premier international forum for all stakeholders including academia, industry and policy decision makers to present and share latest findings in all aspects across this domain, discussing how smart technologies and services can integrate the production and use of energy to support a more sustainable and resilient urban system. CUE2020 was organized by the international journal, Applied Energy and Applied Energy Innovation Institute (AEii), hosted by Sophia University. Due to the COVID-19, the event was held in virtual symposium on Oct 10-17, 2020 for sharing the most recent progress of research RD&Ds in urban energy systems. The Department would like to congratulate Prof. Yang, Dr Cao, Dr Liu and Dr Zhou on the excellent achievement.

Welcome message from the Head of Department

The Department of Building Environment and Energy Engineering (BEEE) was officially established in December 1981 (formerly referred to as the Department of Building Services Engineering). We have been serving Hong Kong’s building services engineering industry ever since, promoting sustainable, efficient and healthy indoor and urban living environments in one of the world’s greatest cities by providing world class teaching and conducting internationally leading research.  BEEE is one of the constituent departments of the Faculty of Construction and Environment, and offers a full range of taught and research based study programmes leading to awards from Bachelor of Engineering (BEng) to Masters (MSc and MEng) right up to Doctor of Philosophy (PhD).   Among many challenges confronting the world, perhaps the most critical is to provide high quality living environments to rapidly urbanising and ageing populations under the creeping threat of a worsening climate and increasing environmental pollution. UN forecasts that the world's population will reach 9.7 billion by 2050. 70% of the people are projected to live in urban areas, placing enormous strain on cities and the environment. To deal effectively with these challenges, future building engineers will need to be data savvy and work in interdisciplinary teams to deliver optimal solutions enabling smart urban environments incorporating elements such as vertical farms; renewables driven integrated buildings and transport systems; citywide recycling and so on for a sustainable planet and a smart and resilient built environment. In order to promote this vision, we have designed state of the art study programmes providing the best possible training to our students in designing high performance buildings and building systems through judicious exploitation of the sciences and contemporary technologies such as sensor and comms networks, AI and IoT techniques, data science and programming, BIM and digital twin systems etc. This is consistent with our mission, stated as, to imagine, engineer and promote sustainable, salutogenic and safe environments for human habitation.   BEEE full-time academic and teaching staff members engage in a wide range of research activities organized in the following three research themes: Building Energy: Energy issues in buildings are addressed in the context of both demand and supply to improve the sustainability of the built environment. Building Environment: Optimisation of buildings and built environments for thermal comfort, indoor air quality, visual/spatial and vibration/acoustic aspects to improve occupant health and productivity. Building Safety and Resilience: Protection of building occupants from hazards such as fire and lightning to improve safety and resilience of communities, buildings and built environments.   I would like to take this opportunity to thank you for your interest in our department and programmes and hope you’ll join us in learning to promote smarter urban environments for a better and more sustainable future for humanity and our planet.   Prof. Asif Usmani Head of Unit Department of Building Environment and Energy Engineering

New Assistant Professor - Dr Cynthia Hou

The Department of Building Services Engineering (BSE) is pleased to announce that Dr Cynthia Hou has been appointed the new Assistant Professor of BSE, starting on 18 August 2021. Dr. Cynthia Hou received her PhD in Real Estate and Construction from the University of Hong Kong and is a member of the Royal Institution of Chartered Surveyors. Before joining PolyU, she worked as an assistant professor in the Department of Management in the Built Environment, Delft University of Technology (2020-2021) and a lecturer in the Chinese University of Hong Kong (2015-2020). She has been engaged in research in the field of built environment management. Her research focuses include post-occupancy evaluation, workplace management, strategic facilities management, and heritage management. Recently, she has leveraged smart technologies in her research by investigating smart hotels, smart heritage facilities management, and virtual reality (VR) technologies applications in built environment education. She seeks to investigate efficient and sustainable built environment management strategies from a facilities management perspective. She is also keen on adopting digitalisation approaches in her research, with an aim to delineating the dynamics among people, facilities and space in the built environment and exploring data-driven solutions for facilities management problems in society.
