What are Building Energy Systems?

• Systems used to provide
• HVAC
• Heating
• Cooling
• Indoor Air Quality (Ventilation)
• Electricity
• Lighting
• Water Management

4
What are Building Energy Systems?

• Building Envelope
• Location Orientation
• Energy Distribution (what is available)
• Energy Generation
• Power management (Control systems)

5
What is Geothermal Energy?

• Energy generated in the Earth (Core)
• Big G has high temperatures
• Used for district heating
• Used for electricity generation
• Energy stored in the Earth (Solar)
• Little g typically lower than 70oF
• Used for heating and cooling, district and
  non-district

6
How is it Transferred?

• Open Loop
• Gas (steam) driven by pressure to surface and
  used to rotate turbine impellers
• Hydro (water) driven by pressure to surface and
  piped into a heat exchanger (HEX)
• Closed Loop
• Glycol or water pumped through a continuous pipe
  (down and up the bore)

7
Bore Field Types

• Open Loop (pump and dump)
• Underground water-source
• Lake
• River
• Etc

8
Bore Field Types

• Closed Loop
• Buried ground-heat exchanger (GHEX)
• Vertical bore field
• Horizontal field (bore or excavate)
• Lake
• Pond
• Municipal water supply
