Abstract
This paper discusses concrete structure design considering the environmental impact generated in the manufacture, construction, service, maintenance, demolition, and disposal and recycling processes of the structure. Environmental impact, including its reduction, is considered as a performance parameter of the concrete structure, similarly to serviceability, safety, and durability. Two types of design methods that respectively verify environmental performance and consider environmental performance are proposed. The design method for verifying environmental performance is applicable when environmental performance is required of a concrete structure. In this type of design, verification of environmental performance is carried out in the planning stage and is followed by inspection in the planning stage as well as the operation stage. The design method for considering environmental performance is applicable whether or not environmental performance is required of a concrete structure. In this type of design, verification or selection of environmental performance is carried out in the planning stage, and inspection is performed in the operation stage. Regarding the verification method, two types of methods are proposed according to the diversity of environmental performance requirements.
