为了阻止二氧化碳浓度导致的全球变暖，应该减少能源使用。日本建筑业的投资约占GDP的20%。这一比例远高于大多数发达国家。这导致日本建筑业（包括住宅用途）消耗了整个工业部门所有能源和资源的约三分之一。为了节约能源和资源，建筑材料的回收利用迫在眉睫。在本文中，我们通过简单的计算方法重点研究了当建筑材料或产品由回收材料制造时潜在的节能效果。我们研究了三种不同建筑技术的住宅建筑，并估算了使用回收材料所带来的能源消耗和资源减少量。结果表明，对于大多数建筑材料来说，用回收材料改造住房材料所需的能源消耗低于制造新住房材料所需的能源消耗。所有案例住宅的建筑材料能耗至少可节省10%。同时，以建筑材料质量（公斤）计算的资源可减少50%以上。 (C) 2001 Elsevier Science B.V. 保留所有权利。
In order to stop the global warmth due to the CO2 concentration, the energy use should be decreased. The investment of building construction industry in Japan is about 20% of GDP. This fraction is much higher than in most developed countries. That results the Japanese building construction industry including residential use consumes about one third of all energy and resources of the entire industrial sectors. In order to save energy as well as resource, the recycle of the building materials should be urgent to be carried out. In this paper, we focus on the potential energy savings with a simple calculated method when the building materials or products are manufactured from recycled materials. We examined three kinds of residential buildings with different construction techniques and estimated the decreased amount of energy consumption and resources resulting from use of recycled materials. The results have 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 at least 10%. At the same lime, the resource, measured by mass of building materials (kg) can be decreased by over 50%. (C) 2001 Elsevier Science B.V. All rights reserved.
