3. Project Objectives Safety LEED Platinum Energy Star 1. Mission Critical

4. Project Objectives 2. Highly Desirable 800 staff Capacity 25kBTU/sf/year Architectural integrity Honor future staff needs Measurable ASHRAE 90.1 Support culture and amenities Expandable building Ergonomics Flexible workspace Support future technologies “ How to” manual Real-time PR” campaign Secure collaboration with outsiders Building information modeling Substantial Completion by 2010

5. 3. If Possible Net zero design approach Most energy efficient building in the world LEED Platinum Plus ASHRAE 90.1 + 50% Visual displays of current energy efficiency Support public tours National and global recognition and awards Support personnel turnover Project Objectives
