Study on indoor pollution by microbes grown in a solar house in Tokyo; Tokyo no solar house ni okeru kabi no jittai chosa

Abstract

Indoor pollution by microbes grown in a solar house is studied. It is a reinforced concrete building, having a total floor area of 260m{sup 2}, equipped with a flat type solar collector on the roof and a lighting window on the north, the former having an area of 16m{sup 2} and slanted at 60deg and the latter slanted at 60deg. It is also provided with a semi-underground room, to utilize heat capacity of soil for coolness in summer and warmness in winter. It provides a residential space throughout the year, with no artificial heating or air-conditioning system, naturally ventilated with air taken into the underground room and released out of a triangular shape on the roof. The building is also passively conditioned, being totally insulated with expanded polystyrene. Energy saving is the most important consideration for the solar house, slightly forcing the residents to exercise patience. For this reason, the solar house often smells musty, and pollution with microbes is quantitatively investigated. Microbes evolve more in the underground room than in the space above groun, because of higher humidity in the former. Accelerated ventilation or slight artificial air-conditioning will solve the trouble. 1 refs., 7 figs.
