The purpose of this literature review is to investigate the reliability of self-evaluation as a method for measuring the effect(s) of indoor environment quality (IEQ) on the productivity of office workers. The aim of this review is to identify the various constraints to its adequacy in measuring productivity.


Thirty studies were selected from peer-reviewed sources and reviewed on their method of measuring productivity. These studies used self-evaluation (questionnaires or interview) as the sole method of measuring the effect of IEQ on productivity/performance.


This review provides insight on the insufficiencies and biases prevalent in self-evaluation. Various issues that compromised the reliability of self-evaluation results in an office environment were discussed. It was concluded that self-evaluation is not reliable and does not accurately measure occupant productivity.

Research limitations/implications

This study has been a review of past studies and their findings. Further studies that will provide empirical evidence are required to solely test the reliability of self-evaluation in measuring productivity and the effect of factors such as IEQ on it.

Practical implications

The paper calls for further debate on occupant productivity measurement and how the various factors that affect it can be quantified into measurable entities.


This paper fulfils an identified need to revisit the technique of self-evaluation as a method for measuring occupant productivity.
