  • Cost of natural gas rose 43%

from 2008-10

  • Cutting edge combined

vertical and horizontal GHX

  • World first combination with

solar thermal and solar PV

  • Addition of piping to connect

HVAC in July 2014 to further increase efficiency of the system (~35MWh/year electricity reduction)

Project Summary

CKB Sustainable Cities Case Study

10

  • Successful demonstration of a combined solar thermal,

solar PV and ground source heat pump system (world first)

  • Net reduction in CO2 emissions: ~210 tonnes/year
  • Equivalent to:
  • Removing 44 passenger vehicles from the road
  • Planting 5,500 seedlings and growing them for 10 years
  • Net saving ~$150K/year (10 year PBP on CKB funds)
  • PBP drops to 8 years with a 5% annual increase in price of

natural gas
