SHRM Online staff  (2010, April 1) said 4,285 full-time U.S. workers that found 22 percent claiming a too-hot workplace makes it difficult to concentrate at work. Eleven percent made the same claim about chilly workplaces.



Workplace performance increases with temperatures up to between 69.8 degrees and 71.6 degrees Fahrenheit (21 degrees to 22 degrees Celsius), with the highest productivity at around 71.6 degrees Fahrenheit.
Lawrence Berkely(N.D.) In 2006, a formal statistical analysis of 24 of these studies was completed to assess the average relationship between temperature and performance of work. The authors primarily analysed office studies and laboratory studies that simulated office work, although three of 24 studies were performed in classrooms. Their analyses are the source of Figure 1 illustrating a best estimate of how office work performance varies with temperature. The graph in Figure 1 shows that performance is maximised when the air temperature is approximately 22 °C. As the indoor air temperature rises above or falls below 22 °C, work performance decreases. The equation for the curve in Figure 1, resulting from the statistical analysis, is
where
P is performance relative to the maximum value
TC is room temperature, °C.
The equation should not be used for temperatures below 15 °C or above 32 °C.
