Module 1 - Introduction to Ground Source Heat Pump (GSHP) Systems

Geothermal Systems are relatively simple to design, but smart and experienced engineers need to understand a few key concepts before they jump into it. This week’s discussion lays the groundwork for a smooth transition into the geothermal industry. Topics covered include: CGD overview, review of GSHP concepts, components & operation, configuration options, advantages & disadvantages.

Module 2 - Building understanding, pre-modeling, and performing a site visit

Doing a feasibility study is a practical first step to take on any commercial geothermal project. Even if there’s not a budget set aside for anything extensive, there are some simple first steps that will pay off down the road by setting realistic expectations for the client and the team. Topics include: understanding engineering duties, feasibility studies, overview of operating cost calculations, system pre-modeling, understanding site characteristics & coupling options, FTC testing, manifolding options, and installation logistics.
