MATERIAL AND ENERGY USE FOR MANUFACTURING COMPONENTS IN BUILDING SERVICES. A CASE STUDY OF AN OLD PEOPLES HOME

摘要

Environmental loads from the building and its services must be minimised. The study aims to determine material quantities, manufacturing energy and how material choice affect manufacturing energy. An inventory of materials in domestic water, waste water, space heating and ventilation services are made and manufacturing energy are calculated based on LCA's. Finally energy need for alternative material choice are calculated. The services consists of more than 30 materials where 8 constitutes 80% of the weight and 10 constitutes 80% of the manufacturing energy. A bad material choice can increase the manufacturing energy need by 29% compared to a good choice.
