Indoor Environment

Improving indoor environment quality in buildings with a human-centric approach.

Synergising expertise from diverse disciplines to facilitate built environments that deliver positive health, comfort, and performance benefits to building occupants.

Since we spend on average around 90% of our daily lives inside buildings, their indoor environment quality can significantly impact the health and wellbeing of their occupants. Indoor environment takes the lion’s share of building energy consumption, for example, 40% in HVAC and 25% in lighting. Thus, design strategies for sustainable buildings need to optimise the balance between energy efficiency on the one hand and indoor environmental quality on the other. 

Our approach

Our approach is to leverage a wide range of nanotechnologies to deliver high quality occupant-centric building designs and strategies (indoor climate, illumination, acoustics, ventilation, and air quality). Our focus is on occupants’ comfort, health, performance and productivity, as well as energy sustainability and net-zero emission.

Buildings are for people and most of their energy demand relates to the thermal, ventilation, and illumination requirements of their occupants.
