This study aims to analyze about the evaluation of home builders what factors contribute to the improvement of thermal insulation performance of new detached houses. The analysis focuses on five factors; the financial incentives to home buyers, the standard of energy efficiency to home builders, the building performance labeling, market needs, and technical factors of insulation. I conduct an empirical analysis based on questionnaire survey of 180 home builders. The result shows that large-scale company provides relatively more houses with better insulation property. Most of home

recognize the influences of financial incentives and next is market needs. The result also implies that the “ Eco-point ”， which is a financial incentive widely used, contribute to promote the adoption of better insulated windows, and to stimulate particularly small contractors to use insulating materials.It is also implied that the comfort and reduction of energy bills are equally recognized as benefits of insulation.
