Indoor Air Quality Audit based on Singapore National Environment Agency (NEA) Guidelines
The indoor air quality of air-conditioned offices is a subject of public health importance because most of us spend a substantial amount of time in such premises. Good indoor air quality can lead to improved productivity at the workplace. On the other hand, poor indoor air quality will cause productivity to drop because of comfort problems, short and long term debility and sickness.
