Project Outline

IGES is a think tank whose aim is to research policy-oriented or practical measures designed to solve problems of the global environment, and to concretize the results of such research via the policies of governments and local authorities as well as the actions of corporations and citizens in various countries. The design concept was to create a practical yet comfortable, highly flexible research environment that can support research spanning different sectors flexibly over the long term, bearing in mind that such research changes every few years. Another objective was to positively introduce passive technologies that draw on the superb natural environment inside the site, and to present this as a prototype for eco-friendly architecture befitting this Institute.

These cases are described based on assessment results obtained using CASBEE.
CASBEE is a method for rating the environmental performance of buildings using Building Environmental Efficiency (BEE) as an indicator, which is based on the results of separate scores obtained for Q-1~Q-3 (Quality) and LR-1~LR-3 (Load Reduction).
