Case study on indoor thermal environment during winter and energy consumption of apartment houses in cold climatic region

In cold climatic region, more and more detached houses were getting to be thermally well insulated and less infiltration. On the other hand, quality of indoor thermal environment in apartment houses which would have lower thermal insulation and infiltration than in detached houses is likely to be not good. Measurements were carried out to evaluate indoor thermal environment during winter and energy consumption of eight apartment houses located in Akita Prefecture.
