## Sustainable Building Rating Systems

- tools that examine the performance or expected performance of a ‘whole building’
- translate that examination into an overall assessment
- allowing comparison between buildings

## Identification

- Literature reviews
- Internet searches
- Presentations
- Publicly available information
- January – April 2006

## Summary

- GSA needs:
- A system that is applicable to the large scale and complexity of federal building projects.
- A stable rating system such that the evaluation of building performance is not subject to drastic change.
- A system which tracks quantifiable achievements in sustainable design and is third party verified by a qualified assessor.
- A system used in the current market with practitioner 	     awareness.
