Sekisui House, one of Japan’s leading house construction companies, launched a new steel framed house, many of whose parts are covered with heat insulation materials. Unlike the existing house, not only the beam and columns but also ceiling, floor, and walls are covered with heat insulation materials in this new house. It can reduce utility costs and carbon dioxide emissions by 35-50%, respectively, more than the existing house. By increasing the strength of structural members like steel beam, reinforcing steel, and wall, the company successfully secured as much as 6-meter opening of windows, large eaves, blow-by, and veranda to give the house even more openness specific to a Japanese house. The new house is named Be Saie, and it costs \600,000 and more per 3.3 square meters.
