There is a close correlation between a person’s performance and the temperature of his immediate surroundings. An environment that is too hot, too cold or too damp will certainly not contribute to higher working efficiency.
The graph illustrates this correlation. Performance begins to drop at about 22°C whilst above 26°C, it falls dramatically. It is important therefore, to keep temperature under control. Please note that the term ‘effective temperature’ is assumed to include humidity.
It is scientifically proven that:
* Accidents tend to occur more frequently during extreme temperatures – the optimum temperature appears to be about 20°C.
* Mental performance and work rhythm drop off sharply when it is too hot.
* Obviously, the provision of a constant environment is subject to many influences.
* For a building to operate comfortably and efficiently, due attention must be paid to its services.
