Effect of Thermal Performance and Lifestyle on the Thermal Environment and Energy Consumption for a Well-insulated and Airtight Detached House in a Warm Climatic Area

Kahori Genjo, Hiroshi Matsumoto

Abstract: This paper describes the effects of thermal performance and lifestyle on the thermal environment and energy consumption for well-insulated and airtight detached houses in warm climatic areas by the measurement and numerical simulation of the thermal environment and energy consumption of a detached house in the Tokai region of Japan. The results of the measurements were 1) the comfort of temperature was evaluated to be high because the vertical temperature difference of the living room was small and 2) the energy consumption was equal to 1.3 times as much as other research in Aichi Prefecture. On the other hand, the results of the numerical simulation were that 1) it was found to be more effective to reduce the usage of the domestic hot water supply and lighting fixtures than it is to improve shelter performance in order to reduce total annual energy consumption, 2) it was effective to consider lifestyle in cases of detached houses with fully high thermal performances in warm climatic areas such as the examined house, and 3) the total annual energy saving effects of changing the number of family members were found to be 2% for 3 people and 8% for 2 people.
