The thermal performance and equipment type specified for a newly built house were investigated as benchmarks to enable the selection of appropriate insulation and equipment specifications. The prevalence of electric heater installations for space heating and hot water supply decreased in 2012, compared to 2011. However, it is estimated that the primary energy consumption is high in particularly cold areas of Hokkaido, because this type of equipment remains common in these areas. Because there is an initiative to contractors when the equipment type is determined, it is important to provide appropriate information to these contractors.
