    3. 3. Many additions between 1895 and 1999
    4. 4. Increased population requires further expansion
    5. 5. Existing 13 acre site – “tapped out”
    6. 6. Purchased new ground at Randall / Big Timber
    7. 7. Plans begin for replacement facility</li></li></ul><li>Sherman Replacement Hospital <br />The Criteria<br /><ul><li> Modern expandable facility
    8. 8. Attraction of a healing environment
    9. 9. Sustainability a primary focus
    10. 10. Patient comfort and safety a priority
    11. 11. Control the rising cost of operation
    12. 12. Energy & Water</li></li></ul><li>Sherman Replacement Hospital <br />Why Geothermal<br /><ul><li>Visited Great River Medical Center as a model
    13. 13. Required storm water detention
    14. 14. Met the requirements of resource conservation
    15. 15. Healing environment enhanced with large lake</li></li></ul><li>Geothermal +/-<br />Pros<br />Cons<br /><ul><li>Uses less energy
    16. 16. Uses fewer natural resources
    17. 17. Reduces operating costs
    18. 18. No cooling towers / chemicals
    19. 19. Increased marketing potential
    20. 20. Therapeutic value
    21. 21. “Buy in” and training
    22. 22. Added first cost for lake or wells
    23. 23. Requires extra acreage
    24. 24. Maintenance of heat pumps
    25. 25. Shorter equipment life</li></li></ul><li>Hospital Energy Usage<br />Hospitals among most complex and energy intensive facilities.<br />Hospitals spend $5 billion annually on energy.<br />Represents 1% - 3% of typical hospital’s operating budget or an estimated 15% of profits.<br />
    26. 26. Sherman Stats<br /><ul><li>650,000 SF greenfield campus
    27. 27. Opened late 2009
    28. 28. Planned to build 5-acre lake, extra 10 acres required for total 15-acre lake
    29. 29. $400,000 grant from Illinois Clean Energy Community Foundation
    30. 30. $1,000,000 grant from DOE</li></li></ul><li>Sherman Geothermal<br /><ul><li>15 acre, 18’ deep lake provides 2400 tons of cooling
    31. 31. Can expand to 3400 tons in future within lake footprint
    32. 32. 175 heat exchangers (150 miles of piping) at bottom of lake
    33. 33. 750 water-to-air heat pumps for comfort cooling
    34. 34. 50 water-to-water heat pumps for infrastructure
    35. 35. Water level maintained with two wells</li></li></ul><li>Energy Efficient Design Concepts<br /><ul><li>Intelligent Lighting systems from occupancy sensors to time zones.
    36. 36. Building automation, programmable thermostats
    37. 37. No Cooling towers (all condenser water returns to closed loop lake)
    38. 38. Water = low flow faucets, shower heads, toilets.
    39. 39. Tankless water heaters
    40. 40. Windows = low “E” glass
    41. 41. Recycling programs include: cardboard, plastic, glass, paper & metals, lamps, batteries, oil, (fryer and motor) </li></li></ul><li>Sherman Geothermal<br /><ul><li>Lake serves multiple purposes

    43. 43. therapeutic healing environment
    44. 44. storm water retention
    45. 45. Excavated fill used to raise building 5’ for greater presence
    46. 46. Irrigation system uses water from lake rather than city
    47. 47. Manifold Room educates public about renewable energy</li></li></ul><li>Sherman Financial Analysis<br />Existing Facility Energy Costs 2009<br /><ul><li> Electric/Gas/Water $3,567,682
    48. 48. $/ Ft 2 $ 5.91</li></ul>Estimated New Facility Energy - Conventional<br /><ul><li> $5.91/Ft2 x .90% Eff. Gain= $5.32/Ft2
