Building Environment

image1
Research in this area has helped improve indoor and outdoor environments, such as HVAC systems to control indoor air temperature and humidity for thermal comfort and energy efficiency. Improving indoor built environments involves thermal, indoor air quality (IAQ), visual and acoustic aspects. Technology enabling ventilation and sound insulation has been applied in hostels, public housing estates and a private housing estate.
