• Did not consider structural effects of locating
  boiler and chiller on roof additional 200,000.
• Revised Estimated Cost 1,700,000
• Redesign
• 100 Outdoor air geothermal system
• Estimated Cost 1,500,000

26
Mechanical System

• 100 Outdoor Air Geothermal System
• Energy-efficient
• Environmentally clean
• Cost effective
• Minitab Geothermal System
• 40,000 lf of pipe 100 wells _at_ 400 ft. each
• 278 high-efficiency heat pumps
• Air to air heat recovery system

27
Geothermal System
28
Geothermal System
