Indoor Air Quality Concepts, Technologies and Solutions for a Sustainable Built Environment

Course Overview

Building designers, contractors, owners and managers have long been challenged with providing quality indoor environments at a reasonable energy cost. Current efforts to improve building energy efficiency, including goals of sustainability and net-zero energy use, are bringing more focus on how to simultaneously achieve energy efficiency and good indoor air quality (IAQ). While energy efficiency and IAQ are sometimes viewed as incompatible, there are many strategies that support both ends.

This training delves into many elements of healthy, productive, energy-efficient, and sustainable buildings. Multiple strategies, specially formulated for the tropics, will be discussed. These strategies bring benefits of good indoor environmental conditions, energy savings, water savings and protection of buildings occupants from pandemic threats.

The launch of the Singapore Green Plan 2030 by the Singapore government highlights the importance of galvanising a whole-of-nation movement to advance Singapore's national agenda on sustainable development. This compact training programme shares fundamental concepts and principles on holistic building design – a cornerstone for creating infrastructure that supports occupant well-being.
