This paper (Part 1) gives an outline of the series of this productivity research and presents on the results of field intervention experiment. Here, we focused our attention on the effects of air change rate and studied thermal / air environmental effects on academic performance. The field intervention experiment was conducted in actual classroom with actual students, during normal lessons. It also involves quiz that are a part of a teaching curriculum. When air change rate is increased from 2.6 to 18.6m^3/h per person, academic performance evaluated by quiz score is improved significantly by 5.8% on average (p<0.0007). Similar trends were observed for self-estimated performance. Correlation analyses show that lower air change rates link to reduced academic performance. This experiment indicates that improving indoor environment conditions in classroom can substantially improve academic performance.

The water retentive pavement is effective in alleviating the summer heat in urban areas. The purpose of this experimental study is to estimate the thermal environment created by the water retentive pavement. The pavement used in this study is constructed using concrete block made of used thermal insulation foam. And the condition of this road surface is wet in the daytime under fine weather. The feed pump driven by solar power generation supplies stored rainwater toward this pavement. The main results of our outdoor experiment can be summarized as follows: 1) There is a good correlation between the surface temperature of the block and the ratio of water contained in the pavement. The water ratio calculated with empirical formula using the surface temperature measured under fine weather mostly agrees with the experimental value of the water ratio. 2) The alleviation effect of this pavement is generated in the afternoon. To put it concretely, in comparison with asphalt pavement on the windward side, the air temperature at a height of 1.1 meters decreased from 1 degree to 2 degrees. The maximum of decrease in SET at a height of 0.6 meters is 2 degrees lower than asphalt pavement on the same direction of the wind. However, there was no change in SET at a height of 1.1 meters. 3) The trend of deterioration produced by an increase of absolute humidity caused by the evaporation of the water retentive pavement is mostly negligible.
