HEATING METHODS IN THE MAIN BEDROOM AND THE SPACE AROUND THE LIVING ROOM DURING WINTER : A case study of the thermal environment in the houses and their residents' lifestyle in Kansai area Part2

Abstract

We investigated the actual status of the thermal environment and heating methods in the main bedroom and the space around the living room in 15 prefabricated houses built in the Kansai area with approximately 25% higher insulation capacity than the new energy-saving standard. The results are summarized as follows : 1) All of the residences surveyed have a heating apparatus in the main bedroom. But residents use them for a very short time because they seldom use the main bedroom for any purpose other than to sleep. 2) The temperature of the corridor is low the whole day, because that is a non-heated space. The difference in temperature between the corridor and the LDK is about 5-15℃ in the evening. 3) Residents with the intention of trying to extend the heating space to the room adjoining the LDK, the corridor and so forth were not observed.
