Integrated life-cycle analysis

There is a structural distinction between assessment tools for green buildings and integrated, life cycle oriented design tools. The criteria for life cycle integrated design tools are listed. They concern the scope of the methods as well as their scalability. The basic methods and assumptions of the integration of Life Cycle Analysis, in particular energy and massflow analysis, into the normal work environment (CAAD, specification and quantity surveying, energy need and building physics calculation, comfort and health risk appreciation) are presented. The first experiences from the application of an integrated tool are discussed. Conclusions concern the time span for the development and the diffusion of new tools in the planning process.
