Passive design strategies in traditional Japanese architecture: A case study of the Chochikukyo house

Abstract

The Chochikukyo house showcases the fusion of traditional Japanese architectural principles and contemporary ecological design methodologies. This study assesses the impact of various design elements on the energy efficiency, comfort, and environmental compatibility of a house. These elements include building orientation, layout and dimensions, size and height, eaves and shade from plants, height from nearby ground, material selection, proper air circulation, cooling in the summer, and positioning of underground pipes for cool air. Through the optimization of building orientation and layout, the house effectively utilizes passive solar heating and cooling, resulting in a substantial reduction in energy requirements. Strategic material selection and the integration of natural cooling and ventilation techniques improve thermal comfort and indoor air quality while reducing dependence on mechanical systems. The combined impact of these measures has the potential to decrease total energy usage by 40-50%, showcasing the effectiveness of incorporating conventional design features into modern sustainable building. This study emphasizes the significance of comprehensive design strategies that harmonize with natural environmental conditions in order to attain energy-efficient, comfortable, and sustainable living spaces.
