Good indoor environment quality (IEQ) can have a positive impact on the health, wellbeing and productivity of occupants in office buildings. Productivity benefits can potentially be financial as well as intangible in nature, and can be realised at both individual and organisational levels. This paper discusses key aspects of IEQ, in the context of occupant health and productivity, and outlines some specific strategies to assist in delivering high quality indoor environments. It should be noted that good IEQ is a necessary, but not sufficient pre-requisite for enhanced productivity, since other factors, specific to individual contexts, and not directly related to IEQ, can also have a significant impact.
