  12. Mechanical Systems Existing Heating: Mechanical Option

  13. Mechanical Systems Proposed Mechanical: • Geothermal Heat Exchanger • Ground Water Heat Pump System • Surface Water Heat Pump System • Zonal Heating and Cooling Control Mechanical Option

  14. Mechanical Systems Proposed Heat Pump Locations: Heat Exchanger Mechanical Option

  15. Mechanical Systems Geothermal Exchanger Heat Pump: 11x7 Hole Borefield Mechanical Option

  16. Mechanical Systems Geothermal Exchanger Heat Pump: Mechanical Option

  17. Mechanical Systems Ground Water Heat Pump Projection and Injection Wells Mechanical Option

  18. Mechanical Systems Ground Water Heat Pump Mechanical Option

  19. Mechanical Systems Surface Water Heat Pump 19x19 300' Spools Mechanical Option

  20. Mechanical Systems Surface Water Heat Pump: Mechanical Option

  21. Mechanical System Selection Which is the Best Heat Pump Solution??? Mechanical Option

  22. Mechanical System Selection Ground Water Heat Pump Advantages: • Less Drilling for Wells than Geothermal Piping • Less Piping required than Surface Water or Geothermal • $76,960 savings over Geothermal • $676,685 savings over Water Source Mechanical Option

  23. Daylighting Existing Warehouse Lighting: • 190 - 400 Watt Metal Halide Fixtures • 140 - 180 Watt Fluorescent T8’s = Total 101,750 Watts Installed Warehouse Daylighting: • 3 Sets of 3’ high windows length of Warehouse • Visible Transmittance of 0.50 • Window-to-wall Ratio = 0.36 Mechanical Option

  24. Daylighting 3' Clerestory 3' Clerestory 3' South Window Mechanical Option

  25. Daylighting Summer / Clear Sky Illuminance • 275 Fc on Floor • 130 Fc on Can Sides Mechanical Option

  26. Daylighting Winter / Overcast Sky Illuminance • 30 Fc on Floor • 22 Fc on Can Sides Mechanical Option

  27. Daylighting Mechanical Option

  28. Daylighting Summer Month Peak Savings: • 64 kilowatts • $186 Winter Month Peak Savings: • 25.6 kilowatts • $75 Mechanical Option

  29. Structural Redesign Existing Roof Structure: • Pre-fabricated Wide-Flange Steel Beams Redesigned Structural Members: • New Joist-Girders • 3 sets of 3’ high windows required (= 2 clerestories) • 10’ opening for clerestory for length of warehouse (737’) Mechanical Option

  30. Structural Redesign Clerestory Span Column Line Mechanical Option

  31. Structural Redesign Modified Joist Girders Mechanical Option

  32. Conclusions • Ground Water Heat Pumps are Economical for the Pittsburgh Environment • Heating and Cooling provided in all spaces • Daylight reduces Power Demand, and Provide Natural Sunlight • Joist Girders supply needed strength and span Warehouse requires Mechanical Option
