Life-Cycle Evaluation of Ecobalance Performance of Ecomaterial-Type Building Materials by Multiple Eco-Indicator Method

Abstract

Ecomaterial-type building materials are classified based upon 6 row×8 column eco-life-cycle matrix table combining 8 life-cycle stages of resources gathering, transportation, production, assembly/construction, in-service/maintenance and modernization, demolition, recycle/reuse/reproduction, and reduce/final waste with six eco-balance evaluation items of long service life, resources circulation, reduction of harmful substances, resources and environmental capacities, materials efficiency ,and health safety. Evaluation indicators other than life cycle inventory (LCI) are shown as methods of ecobalance performance. In each life stage, each ecomaterial is evaluated as radar chart by 5 step indices by six eco-balance evaluation item (multi eco-indicators）.
