| Research Abstract |
The goal of this research program is to establish an evaluation and control method of in door air quality especially in low energy houses. We performed the multi-component measurements of indoor air quality in energy-efficient houses including Hokkaido University low energy house together with the literature survey. The measurement items of indoor air quality consisted of 1) air temperature, 2) relative humidity, 3) carbon dioxide (COィイD22ィエD2), 4) carbon monoxide (CO), 5) suspended particulate (SPM), 6) radon daughters, 7) air-borne bacteria, 8) airborne fungi, 9) formaldehyde (HCHO), and 10) volatile organic compounds (VOCs). By using the multi-component measuring data we conducted a mathematical analysis of indoor air quality. On the other hand we developed database of low energy techniques for houses in the world. Input data of the database are composed of seven chapter and 155 items, and 66 houses have been recorded from 17 nations. Several newly equipments using renewable energy were tested for their energy efficiency.
The effectiveness of 1) passive ventilation system, 2) mechanical ventilation system and 3) hybrid ventilation system were examined in low energy houses of both Japan and Canada.
