Abstract
The effect of soil-based material on the controllability of indoor climate was investigated. The material produced by a hydrothermal reaction had higher moisture adsorbing/desorbing ability than wood and almost the same heat capacity as concrete. The utilization of soil-based material as an interior floor finishing one reduced variation in temperature and humidity inside the room as well as residential energy consumption. Furthermore, numerical simulation was applied to estimate thermal control property of the material in indoor space.
