Abstract

The objective of this study was to design and construct an insulation-retrofitted, downsized house and examine the thermal comfort of the house. In the retrofitted house, the total floor area was reduced, and the thermal insulation of the living area was improved. Field measurement of the thermal environment was conducted in autumn 2021 and winter 2022 in Morioka City, Japan. In this house, a new open-air deck space was constructed by reducing the old outer walls. In autumn, the predicted mean vote (PMV) in the living-dining room was within ±0.5 without running the air conditioner. Furthermore, while the residents lived in the house, the standard new effective temperature remained within the comfort zone in the deck space. In winter, it was shown to have high health benefits by the floor surface temperature increases with running the floor heating.
