title: The effect of the environment of human performance.
abstract: The performance of man, for a given level of ability, will be affected by his hygro-thermal, electro-ionic, visual and psychological microclimates. This paper presents the results of studies which demonstrate the effect of the hygro-thermal micro-climate on worker performance. The effects of the other micro-climates on worker performance are also discussed. For tasks with mainly physical activity performance depends upon metabolic heat. For tasks with mainly psychological activities there have, until now, been no specified criteria for determining the effects of the environment on performance. Consideration of the results of studies conducted in working environments clearly shows that environmental conditions can effect the efficiency of workers and hence that there are sound economic arguments for optimising working conditions.
