Smart City Solutions
The general idea of “Smart City” goes beyond the use of information and communication technology to minimise the demand for resources and to reduce emissions. It also means enhancing city efficiency, promoting business productivity, improving quality of life and enhancing climatic resilience.
With Smart City as one of City University of Hong Kong’s three overarching themes, researchers from different disciplines are working to provide innovative solutions to address regional and global concerns about sustainable economic development, and to promote high quality of life and harmony between the built environment and nature.
Research on Smart City
A research team from the department of electronic engineering and division of building science and technology at CityU developed a smart thermostat for central air-conditioning systems in buildings, which can save more than 10 per cent on power use and improve indoor comfort levels. The innovation has been launched on the market.
Advancing millimeter-wave antenna technology to provide fibre-like wireless connectivity has been one of the main research goals of the State Key Laboratory of Millimeter Waves at CityU. Experts at the SKLMW developed the antennas for 5G wireless communication more than a decade ago. With the launch of 5G communication transmitting signals on the millimeter-wave spectrum, they have continued to develop various ultralight and small antennas, which could be used in a variety of applications.
The SKLMW also developed a wireless sensor network system that can accommodate smoke detectors, burglar alarms, and temperature and humidity detectors, and be monitored through the internet.
Professor Li Qiusheng, from the Department of Architecture and Civil Engineering, and his research team have made a significant contribution to enhancing building safety through the systematic study of boundary layer wind characteristics and wind effects on structures. They have developed a wind and structural monitoring system to monitor wind action and pressure from typhoons on curtain walls and buildings, as well as structural responses, which provide reliable guidelines for wind-resistant designs for super-tall buildings. The systems have already been installed in a number of financial landmark buildings in Hong Kong and southern China.
Collaboration with global leaders
Our research has received support from local public institutions, contracts from overseas utility enterprises and grants from other donors. For example, we collaborated with Alstom, a global power company, in such fields as smart grids, power electronics and nanotechnology. And an established local electricity company provided financing for research on green energy and related development projects, as well as to set up a green energy showcase centre.
Our Centre for Smart Energy Conversion and Utilization Research is now cooperating with General Electric in the US to develop a sustainable development smart campus, with the aim of creating a community energy control system that can help reduce waste and make the most efficient use of our energy resources.
