In order to stop the global warmth due to the CO_2 concentration, the energy use should be decreased. Construction industry in Japan consumes about 1/3 of energy in the whole industries and a large of resource materials. As a result, construction also discharges huge waste, about 20% of that in the whole industries. In order to save energy as well as resource, the recycle of the building materials should be urgent to be carried out. In this study, the method to calculate the energy consumption to reuse, renew and remake housing materials has been presented. By using this method, the energy consumption of building materials in three residential houses with different construction method has been compared with recycled and non-recycled selection. The result has shown for most building materials, the energy consumption needed to remake housing materials from recycled materials is lower than that to make new housing materials. The energy consumption of building materials in all case-study housing can be saved by about 10%. At the same time, the resource, measured by mass of building materials(kg) can be decreased by over 50%.
