A Study on Actual Conditions of Thermal Environment and Indoor Air Quality in a Japanese Traditional House Corresponding to Sericulture

This study of the traditional sericulture residence, located inside the Minkaen, Jidayubori Park, Setagaya Ward, Tokyo, Japan, aims to clarify the environmental characteristics of a sericulture building from the engineering point of view. In sericulture, the silkworms are raised at different locations depending on their age. Therefore we describe the actual conditions of the thermal environment such as temperature and humidity when the silkworm is breeding, and the air quality such as CO2, CO, VOC, and carbonyl compound from the silkworm hearth. In addition to these factors the ventilation rate in each part of the traditional house corresponding to sericulture is determined. Moreover, the ventilation performance of the attic and the monitor roof is investigated. The mechanism of thermal conditions, IAQ and ventilation rate was clarified in this paper for the first time using the three-dimensional heat fluid simulation software. As described thus far, we have clarified the environmental situation in a sericulture house from the engineering point of view.
