CaliforniaGeo is pleased to offer a series of online regular meetings we call The Underground  for registered participants.  Our productions will be offered using our Zoom platform, lasting approximately one hour, Noon-to-1pm Pacific Time.  The topic may be an issue, a technique, or a technology—or how certain policies and regulations may affect those.

We will feature a host and presenter, or a panel of two-to-three who will make a short presentation on the subject and then take live or chat-based questions from the audience.  These will be free for CaliforniaGeo professional and affiliate members, and $10 for others. Membership will be verified after registration before access is provided.  Participation is limited.

A Geothermal Retrofit At Colorado State University

 CSU (Fort Collins) recently geo-retrofitted their athletic complex, encompassing 3 buildings, to eliminate an antiquated, leaky steam heating system and added cooling to their indoor arena and other spaces for competitive sports and summer events.  The large bore field will also serve a future Phase II, adding an interconnection enabling a new residence hall complex to share the same GHEX. This will become a larger “district loop,” further optimizing energy efficiency of the geothermal heat pump systems by sharing loads between buildings and their use schedules.  Trey Austin and his company were there.


  How to plan for a large/medium scale geothermal bore field for multiple buildings.

•  Challenges for retrofitting an existing system with respect to heating and cooling coils.

•  Factors to consider for future system tie-ins.

Trey has 26 years of experience with geo systems and is a PE and CGD.  His company, Geo-Energy Services, LLC has a 650 project portfolio stretching from the USA to Asia, Central America, and the Caribbean.  Beyond design-build projects of all sizes, he brings 3rd party financing to large projects as thermal utility agreements.

CaliforniaGeo is pleased to bring Trey to launch our first UNDERGROUND learning session!
