Entertainment clubs, nightclubs, theaters, restaurants, and coliseums, with their highly variable occupancy rate, are excellent candidates for demand-controlled ventilation. The dynamic thermal requirements of both heating and cooling, coupled with the need to control indoor air quality because of the large number of patrons who also may be smoking during the highest occupancy, provide an opportunity to integrate the temperature controls with an indoor air quality control system.

Custom software to automatically administer questionnaires on computer screens was installed on computers in four open-plan offices. Five questions related to thermal comfort were presented twice per day for three months. Results indicate that this new method of subjective data collection was successful and efficient: the participants had few complaints about the method of questionnaire delivery, and a substantial literature review demonstrates that our results are comparable with results from other field studies of thermal comfort conducted using different methods.

A passive solar house with sunspace made of reinforced concrete was constructed in Sendai, Japan in 1984. One year measurement of room temperatures were recorded. Also, detail measurements have been made during the summer and winter seasons. Further, calculation of indoor temperature was conducted using response factor methods for studying the thermal effects of the sunspace on the indoor environment. This paper describes the measurement and calculation results.

The concept of dynamic insulation, where cold air is drawn through porous insulation in a building envelope from outside to inside, thereby returning heat energy normally lost by conduction back into the interior of the building, has been studied by several researchers, in Japan, Europe and Canada. However the work to date has largely concentrated on the physical processes in individual wall, floor or roof elements and only a small number of experimental buildings (all of a small domestic scale) have been adequately monitored.

Hokkaido is distinguished from the other island of Japan by having colder winters and cooler summers. The average monthly minimum is about -10 °C and summer daily average maximum around 25°C, so that efficient space heating becomes the dominant aspect But on hot days the temperature may reach 35°C, though for short period of time. There are few houses constructed to prevent overheating ID summer. I have designed and built a house for my family ID Sapporo which has cavity walls of concrete blocks insulated with urethane 100mm thick and deeply recessed, but operable widows.
