Certified GeoExchange Designer
Designing GSHP systems will keep you competitive in a market forced to deal with rising energy costs.
Certified GeoExchange Designer (CGD) Course
Designing GSHP systems will keep you competitive in a market forced to deal with rising energy costs and resource depletion by offering customers a low-maintenance, economical and green alternative for their space conditioning needs. Federal and state tax incentives for GSHPs are providing additional demand and popularity for the systems, creating even more opportunities for home owners and commercial buildings.
As an engineer or architectural designer, you have specific questions about GSHP systems that you want answered. IGSHPA has designed a program to offer advanced training towards certification as a Certified GeoExchange Designer (CGD). From an introduction to the technology to a complete review of the design process, participants learn the specific information they need to know.
You have two options available for the CGD course – our distance learning option and our CGD Plus course. The distance learning option gives you the convenience of learning when you have the time; while the CGD Plus course provides three days of concentrated learning under the guidance of an experienced GSHP Professional.
Who Should Enroll?
This design course is created for professional engineers, registered architects, installers, and contractors. This course is essential for individuals wanting advanced training and experience in designing GSHPs, and required for experienced individuals who wish to earn certification.
