Geothermal design and innovative approach allow for many benefits at the Portland Jetport

$3.3 million

saved in capital cost

Up to $300,000

saved in annual fuel costs

900+ tons

of emissions reduced annually

Summary

  • Haley & Aldrich’s geotechnical team designed a new geothermal/ground source heat exchanger system to heat and cool the new terminal the Portland International Jetport needed to accommodate a 50% increase in passenger volume.
  • Our innovative approach involved applying new geothermal design and sizing techniques to optimize the system, reducing its size by 25% without sacrificing emissions reduction, which saved the client $3.3 million compared to the original design.
  • By achieving a significant emissions reduction, the client won a grant worth $2.53 million, allowing them to pay back the system capital costs in under five years.
