Productivity and indoor climate

As effort for energy conservation, Japanese government recommend to keep an office temperature setting of 28 degrees C in summer. However, even though knowing the importance of effort for energy conservation, it must be difficult for business administrators or office building owners to put it into action without considering the economic effects and office worker's productivity. To promote the effort for energy conservation, it is importance to estimate the indoor environmental quality from the aspect of office worker's productivity. Our subjective experiments on the effect of moderately high temperature on productivity were mentioned and the balance of environmental concerns and office productivity were discussed.
