Enhancing the Healing Environment with Geothermal Energy - Sherman Hospital Enhancing the Healing Environment with Geothermal Energy - Sherman Hospital Presentation Transcript

  • Enhancing the Healing Environment with Geothermal Energy
    Sherman Hospital – case study
  • Sherman Replacement Hospital
    The Project
    • Originally opened in 1888 – 4 beds and 1 OR
    • Many additions between 1895 and 1999
    • Increased population requires further expansion
    • Existing 13 acre site – “tapped out”
    • Purchased new ground at Randall / Big Timber
    • Plans begin for replacement facility
  • Sherman Replacement Hospital
    The Criteria
    • Modern expandable facility
    • Attraction of a healing environment
    • Sustainability a primary focus
    • Patient comfort and safety a priority
    • Control the rising cost of operation
    • Energy & Water
  • Sherman Replacement Hospital
    Why Geothermal
    • Visited Great River Medical Center as a model
    • Required storm water detention
    • Met the requirements of resource conservation
    • Healing environment enhanced with large lake
  • Geothermal +/-
    Pros
    Cons
    • Uses less energy
    • Uses fewer natural resources
    • Reduces operating costs
    • No cooling towers / chemicals
    • Increased marketing potential
    • Therapeutic value
    • “Buy in” and training
    • Added first cost for lake or wells
    • Requires extra acreage
    • Maintenance of heat pumps
    • Shorter equipment life
  • Hospital Energy Usage
    Hospitals among most complex and energy intensive facilities.
    Hospitals spend $5 billion annually on energy.
    Represents 1% - 3% of typical hospital’s operating budget or an estimated 15% of profits.
  • Sherman Stats
    • 650,000 SF greenfield campus
    • Opened late 2009
    • Planned to build 5-acre lake, extra 10 acres required for total 15-acre lake
    • $400,000 grant from Illinois Clean Energy Community Foundation
    • $1,000,000 grant from DOE
  • Sherman Geothermal
    • 15 acre, 18’ deep lake provides 2400 tons of cooling
    • Can expand to 3400 tons in future within lake footprint
    • 175 heat exchangers (150 miles of piping) at bottom of lake
    • 750 water-to-air heat pumps for comfort cooling
    • 50 water-to-water heat pumps for infrastructure
    • Water level maintained with two wells
  • Energy Efficient Design Concepts
    • Intelligent Lighting systems from occupancy sensors to time zones.
    • Building automation, programmable thermostats
    • No Cooling towers (all condenser water returns to closed loop lake)
    • Water = low flow faucets, shower heads, toilets.
    • Tankless water heaters
    • Windows = low “E” glass
    • Recycling programs include: cardboard, plastic, glass, paper & metals, lamps, batteries, oil, (fryer and motor)
  • Sherman Geothermal
    • Lake serves multiple purposes
    • thermal source
    • therapeutic healing environment
    • storm water retention
    • Excavated fill used to raise building 5’ for greater presence
    • Irrigation system uses water from lake rather than city
    • Manifold Room educates public about renewable energy
  • Sherman Financial Analysis
    Existing Facility Energy Costs 2009
    • Electric/Gas/Water $3,567,682
    • $/ Ft 2 $ 5.91
    Estimated New Facility Energy - Conventional
    • $5.91/Ft2 x .90% Eff. Gain= $5.32/Ft2
    • Electric/Natural Gas/Water $3,434,000or $5.32/Ft2
    Project Goal for New Facility Energy Costs 2010
    • Electric/Natural Gas/Water $2,650,000 or $4.10/Ft2
    Actual New Facility Energy Costs 2010*
    • Electric/Natural Gas/Water cNatural G$2,184,130 or $3.38/Ft2
    • Extrapolated for incomplete (11 Months) 1st year

  • Sherman Energy Analysis
    Existing Facility
    2009 – Fully Occupied 350,260 BTU / Ft2/ YR
    2010 – Partially Occupied 225,760 BTU / Ft2/ YR
    New Facility
    2010 – Fully Occupied 164,200 BTU / Ft2/ YR

  • Sherman Water Consumption
    Existing Facility
    2009 – Fully Occupied 85.38 GAL / Ft2/ YR
    2010 – Partially Occupied 35.48 GAL / Ft2/ YR
