The International Ground Source Heat Pump Association (IGSHPA) recently adopted a new syllabus for the CGD commercial geothermal design course. On Dec 2 and Jan 6, at 11:00 am till noon CST, I will be providing a free, 1 hour webinar as an introduction to the new course syllabus. You must register to get a password for the intro (we are limited to 25 participants). The CGD course focuses on... the differences in designing a large commercial geothermal system compared to designing a conventional heating, ventilation and air conditioning (HVAC) system. The difference in design approach is needed because, when you are designing a GCHP system, you are designing both the energy source and energy sink for the system in addition to the building mechanical system. When you're designing a conventional HVAC system, your design work ends at sizing the gas line to meet the peak heating load and selecting a cooling tower or air cooled condenser based on outdoor air dry bulb and wet bulb temperatures on the peak cooling day.
When you are designing a GHX, your client will almost invariably ask you first, "what will it cost to install a geothermal system?", and secondly, "will the energy savings pay for the additional cost of building it?" The new CGD course is designed to help you answer these questions with confidence. The complete CGD course is offered in several formats:
Scheduled courses will be listed on this website, at www.geotrainers.com, and at www.igshpa.okstate.edu Please email me directly or use the form on this website if you have questions or require any clarification. The full course outline can be downloaded in PDF format. Comments are closed.

In my blog I'll be expressing my opinions about what I've the learned about ground coupled heat pump (GCHP) systems over the last 30 years. I've been very fortunate to work with many interesting people who are passionate about this technology...engineers, geologists, mechanical contractors, drillers, excavation contractors...in different parts of the world. I've learned a lot from them and will be using this forum to pass on some of the things I've learned and feel are important. Please feel free to use this information if you feel it's worthwhile...hopefully you can avoid some of the same mistakes I've learned from. Archives
