Regional and cultural issues in environmental performance assessment for buildings

The Green Building Challenge '98 (GBC '98) developed and tested an international assessment system for buildings. An underlying premise of GBC '98 was to allow for regional differences by providing flexibility and weighting of building assessment criteria within an international framework. This was considered crucial for the acceptability of the assessment system as well as for its ability to accurately reflect best local practice. Regional adaptation is complex, however, and raises many considerations that may be in conflict. This paper analyses the importance of integrating regional aspects into assessment tools on the one hand and the benefit of setting up an international assessment system on the other. An approach for achieving a balance between the regional and international levels of a universal assessment system is discussed. Issues and proposed solutions for further consideration are raised along with suggested topics for further research.
