Enhancing the Healing Environment with Geothermal Energy - Sherman Hospital Case Study

1. Enhancing the Healing Environment with Geothermal Energy Sherman Hospital – case study

3. Many additions between 1895 and 1999

4. Increased population requires further expansion

5. Existing 13 acre site – “tapped out”

6. Purchased new ground at Randall / Big Timber

8. Attraction of a healing environment

9. Sustainability a primary focus

10. Patient comfort and safety a priority

11. Control the rising cost of operation

13. Required storm water detention

14. Met the requirements of resource conservation

16. Uses fewer natural resources

17. Reduces operating costs

18. No cooling towers / chemicals

19. Increased marketing potential

20. Therapeutic value

21. “Buy in” and training

22. Added first cost for lake or wells

23. Requires extra acreage

24. Maintenance of heat pumps

27. Opened late 2009

28. Planned to build 5-acre lake, extra 10 acres required for total 15-acre lake

29. $400,000 grant from Illinois Clean Energy Community Foundation

31. Can expand to 3400 tons in future within lake footprint

32. 175 heat exchangers (150 miles of piping) at bottom of lake

33. 750 water-to-air heat pumps for comfort cooling

34. 50 water-to-water heat pumps for infrastructure

36. Building automation, programmable thermostats

37. No Cooling towers (all condenser water returns to closed loop lake)

38. Water = low flow faucets, shower heads, toilets.

39. Tankless water heaters

40. Windows = low “E” glass

42. thermal source

43. therapeutic healing environment

44. storm water retention

45. Excavated fill used to raise building 5’ for greater presence

46. Irrigation system uses water from lake rather than city

50. Extrapolated for incomplete (11 Months) 1st year*
