HKU Engineering develops energy-efficient building technologies to reduce solar heat gain and energy consumption
Among the various energy-efficient building technologies that have been developed under the leadership of Professor Christopher Chao (Dean of Engineering and Chair Professor of Mechanical Engineering at HKU), passive radiative cooler and smart window are the two innovative and promising technologies, which are ripe for industries. Passive radiative cooler is a wall panel for building façade to provide cooling effect for indoor environments by radiative cooling without additional energy input. Thermochromic smart window blocks solar radiation at high temperature or allow it in during cold weather by regulating its properties to maintain indoor thermal comfort. Installation of these two technologies reduces solar heat gain and heating, ventilation and air conditioning (HVAC) system for energy consumption in building. More importantly, they require no electricity and are eco-friendly.Read More
The university-level KE Excellence Award was introduced in 2015-16 to recognise the significant impact that our academic staff had made to benefit society. The KE Excellence Award 2020 was awarded to Dr Caroline Dingle, Dr David Baker, Dr Timothy Bonebrake, and Professor David Dudgeon of the Faculty of Science.
The new HKU Innovator Award and the HKU Young Innovator Award have been established to recognise outstanding Faculty members whose innovations demonstrate exceptionally high potential impact (legacy or projected legacy) with transformative results to foster development. The new HKU Innovator Award and the HKU Young Innovator Award were awarded to Professor Chuyang Tang and Dr Ka Wai Kwok of the Faculty of Engineering respectively.Read More
HKU Engineering explores an innovative approach of using AI to reduce energy consumption in chiller plant optimization
The project led by Professor Christopher Chao, Dean of Engineering and Chair Professor of Mechanical Engineering at The University of Hong Kong (HKU), explored an innovative approach to optimize the performance of chiller plant in heating, ventilation and air conditioning (HVAC) system for energy consumption reduction. According to the Hong Kong Energy End-use Data 2020 report published by Electrical and Mechanical Services Department (EMSD), space conditioning accounted for the largest percentage of 18% and 32% in total energy consumption and electricity consumption by end-use, respectively, in 2018. The energy usage related to HVAC system raised rapidly by approximately 15% by 2018 from 2008. To improve the performance of chiller plants, a predictive operational control strategy was developed for chiller plants by employing artificial intelligence technology and big data analysis without any additional equipment installation. Artificial neural network (ANN) was employed to predict the future trend, while particle swarm optimization (PSO) was applied to search for the optimized setpoints for the chiller plants. The implementation of artificial intelligence (AI) in chiller plant can enhance overall energy efficiency, reduce energy usage and improve maintenance practice of the HVAC system, as well as mitigating carbon emission by HVAC system.Read More

HKU engineering team develops handy and low-cost thermography fever detection system for public transportations
A multidisciplinary group of researchers from the Departments of Mechanical Engineering and Computer Sciences led by Dr Fu Sau-chung, Research Assistant Professor of the HKU Department of Mechanical Engineering, has recently explored a low-cost thermography fever detection system which is portable and can be easily accessed and mastered by users. The thermal camera plugin in the current prototype is a commercial product which costs around HK$3,000 per set and this accounts for most of the hardware cost. As compared to other similar systems in the market, the total cost of the current prototype is far lower and the system is more handy. Multiple trials have been conducted at the HKU campus since early May. The research team hopes that this portable thermography fever detection system can be applied in public transportation, such as taxis, shuttle buses and minibuses commonly in the future.Read More
E-Commerce has developed exponentially in the Greater China region in recent years, while logistics, which deliver the orders, have become bottlenecked. Traditional logistics operations are no longer able to cope with the challenges, such as long order fulfillment time and low utilization in space, under fluctuating huge demands. Led by Professor Guo Quan Huang of the Department of Industrial and Manufacturing Systems Engineering, iPark is expected to elevate the logistics services to match the growth of E-Commerce.
The project is delivered in two forms. One is a private form for leading enterprises with operations in the Greater China Region. The other is a public platform that is shared by participating Hong Kong SMEs involved in Ecommerce logistics. Eventually, the platform will be “transplanted” to logistics and industrial parks.Read More
