CPD Webinar - Eco-friendly and Smart Surface Coating to Cool Buildings without Consuming Energy

The webinar will be available at HKGBC CPD Online Training Portal (https://onlinecpdtraining.hkgbc.org.hk/) later after the event.
Please stay tuned.

This webinar is organised by the Hong Kong Green Building Council.

Buildings account for 40% of the world’s primary energy consumption and are responsible for about one-third of global CO2 emissions. One of the major causes of building energy consumption in a subtropical climate like Hong Kong is space cooling during hot days, which is required for human comfort and health. 

The building envelope plays a vital role in the durability and thermal performance of reinforced concrete (RC) buildings and significantly influences the service life, the indoor living environment, and the energy consumption of the whole building.  Surface coating, as a most cost-effective means, can isolate the building envelope from various external hostile environments such as water, UV radiations, carbon dioxide, chlorides that challenge the building’s durability. More importantly, the surface coating can also be functionised to reduce the thermal gradient between the indoor and outdoor environments of the building envelope, so that energy needed to maintain human comfort in the building can be significantly reduced. 

This seminar is concerned with emerging technology, sub-ambient daytime radiative cooling (SDRC), that may provide promising electricity- and cryogen-free pathway for global building energy efficiency (Fig.1). Widespread use of such technology may help mitigate the urban heat island and even global warming. The fundamental principles, materials, recent developments, challenges and opportunities of the SDRC technology are discussed in the seminar. The laboratory and field exposure performance of the SDRC coating is demonstrated using an eco-friendly, smart and highly scalable coating developed recently in the speaker’s group.

Speaker: Prof. Jian-Guo DAI, Professor, The Hong Kong Polytechnic University

A full professor and Associate Head at the Department of Civil and Environmental Engineering, The Hong Kong Polytechnic University, Dr DAI obtained his PhD from Hokkaido University in Social Infrastructure Engineering in 2003 and he joined The Hong Kong Polytechnic University in 2008 after some years of research scientist experience in the Life Cycle Management Research Centre, Port and Airport Research Institute, Japan. Dr DAI has had more than 25 years of research and industry experience in the field of “Innovative Civil Engineering Materials and Structures” in mainland China, Japan and Hong Kong. He is the recipient of many academic awards including the "Best Basic Research Paper Award" of Journal of Composites for Construction from American Society of Civil Engineers, "Distinguished Young Scholar Award" from the Association of FRP for Construction, China Society of Civil Engineers and “Structural Excellence Award R&D Grand Award” from HKIE. He has published more than 300 technical papers (including some 140 SCI papers) and was in the “World’s Top 2% Scientist-Stanford University Releases List (2020)” (Career) in the “Civil Engineering” discipline. Dr Dai has been serving actively many international and regional organizations such as ISO, International Institution of FRP in Construction (IIFC), Asian Concrete Federation (ACF) and Japan Concrete Institute (JCI). He successfully chaired the “8th International Conference on Water Repellent Treatment and Protective Surface Technology for Building Materials” in 2017 in Hong Kong, and very recently his group has invented an eco-friendly multiple functional polymeric coating with waterproofing, self-cleaning and sub-ambient cooling features for improving the durability and reducing the space cooling needs of buildings. This coating development has received widespread attention from the public and was highlighted as “A Smarter Radiative Cooler” by the journal “Science” in its “Editor's Choice”.
