| Outline of Final Research Achievements |
In order to maintain a comfortable room temperature, it is necessary to perform heating and cooling throughout the year as well as in the severe winter and hot seasons. About one-third of the energy used at home is heating and cooling, and management and efficiency are key issues in energy conservation.
In this study, we clarified the energy-saving effect of air conditioners both in summer and winter by laying charcoal in the attic (ceiling) space of an apartment house. And the stress levels of subjects who stayed in the space for a short period of time did not increase statistically in both summer and winter. The utility of laying charcoal was also proved by the fact that in the room with nothing laid on the ceiling, the stress level obviously increases in winter.
