The Thermal Environment and Energy Consumption Efficiency of Light-gauge Steel-framed Residential Houses with External Thermal Insulation Structures Further possibility and potential for energy saving of space warming and cooling as global warming policy

摘要

We have clarified the mechanisms used to prevent concealed condensation and heat bridges in the wall of a light-gauge steel-framed residential house, built with an external thermal insulation structure, from the long-term field measurements of a residential house constructed in Hokkaido, Japan. The key points of our study are:1). Light-gauge steel can prevent a fall in temperature inside the wall by transferring energy from space heating. 2). Light-gauge steel can raise the temperature of self-drilling screws to connect outside and inside wall materials. 3). Computer simulations were used to analyze these mechanisms of thermal heat transfer and distribution. 4). Energy consumption efficiency for space heating is extremely high in this building.This paper details those key points of our study at first. After outlining one of our new technological developments to save energy consumption of space cooling we propose our big possibilities for steel-framed house system to become a global standard of housing system in East Asia.
