Introduction
Buildings are
significant users of energy and materials in a society
and they have a large impact on the natural environment
and resources. To reduce energy use and greenhouse gas
emission, it is very important to promote building
energy efficiency and sustainable building design. In
urban cities like Hong Kong, building energy use
constitutes a major portion of total energy consumption.
It is believed that the potential for energy saving and
improvement of building environmental performance is
large.
Research
Areas
This research theme focuses on studying the key factors,
policies and technologies for building energy efficiency
and sustainable building design. Five research areas
have been investigated with emphasis on Hong Kong’s
situation.
- Analysis
of building climatic data
- Building
energy efficiency standards
- Building
energy simulation tools
- Energy
benchmarking and labels for buildings
- Sustainable
building technologies
