Abstract: In order to supply a basis to develop sustainable eco-buildings and eco-cities in the future, taking into account the resources circulation and the preservation of the environment, concepts and procedures of environment-conscious materials (ecomaterials), environment-conscious materials design (ecomaterials design), and environment-conscious life-cycle design (eco-life-cycle design) are proposed and reported for building structural composite materials, components. and/or systems. Based upon the figure showing resources circulation including materials circulation in building activities, building materials, to begin with, are classified from the viewpoint of their origin, that is, from such reproducible resources as wood , and non-reproducible resources, such as fossils, not by ordinarily from their material types such as organic, inorganic, metallic, and composite materials. Ecomaterial-type building materials are classified and various indicators such as materials efficiency, recylability etc. are proposed and quantified to evaluate ecobalance performance. Ecomaterialization was tried for continuous fiber reinforced concrete (FRPRC), and for short-cut fiber reinforced cement composites (FRC). Examples of application of ecomaterials design and eco-life-cycle design are shown for FRPRC and new external thermal insulation systems, using FRC as exterior materials. It is found that materials efficiency gives the effective evaluation indicator for resources productivity and ecobalance performance, especially for new building materials.
