2. Our Path To Healthcare Sustainability

3. The Path for Today • Why sustainability? • Driver? • Statement for the Provider • Statement for the Community • Statement of Responsibility • Dell Children’s Hospital • Dell Children’s 3BT

4. • Sustainable designs lead to a healthy building philosophy • Our business is providing an environment for helping people get well • It should start with a healthy building • The healthy building concept is now: • The RIGHT thing to do • And it ‘sells’ in many ways Sustainability: Our Perspective

5. 1981 1992 1996 2008 2010 2015 ccrd created ccrd assisted in the creation of Dallas AIA sustainability committee ccrd present Sustainability in Healthcare to International Healthcare Conference ccrd completes over 25,000,000 SF of healthcare project designs Dell Children’s Hospital becomes first LEED platinum certified hospital WSP + ccrd join forces – now have completed 25 LEED healthcare projects Dell Children’s Hospital becomes first LEED Healthcare platinum certified hospital

6. Dell Children’s Medical Center of Central Texas • Awarded LEED Platinum • First LEED Platinum Healthcare Facility • 473,000 BGSF, 169 beds • 32.2 acres on 709 acre Brownfield site • Combined Heat Power Plant (CHP) • Achieved 54 LEED v2.1 points • 23 points MEP related • Represents 43% of total points achieved

7. Combined Cooling Heating and Power Plant • 4.5MW natural gas-fired turbine supplies 100% of the hospital’s electricity • 75% more efficient than coal-fired power plants • Lower emissions of nitrogen oxides and carbon dioxide as a result of efficient combustion chamber technology • Steam, a by-product of the conversion process, is utilized by the hospital and is used in absorption chillers to produce all of the hospital’s chilled water needs

8. Dell Children’s Hospital - Specifics • Individual control capabilities • 96% of occupants have lighting control • Underfloor air distribution in administrative areas • Occupancy sensors and daylight harvesting utilized • CO2 monitoring in high occupancy areas • Reduce outside air under low occupancy • Approximately 1.3 million gallons water saved annually • Dual low flush fixtures, low flow showers, automatic sensors • Energy savings estimated at $1.5 million • Energy measurement and verification system • Maintain and optimize energy usage
