The IGSHPA standards committee produced a Standard Specification document for ground source heat pump systems for IGSHPA members. This specification is to be used as a guideline by engineers, designers, contractors, building owners and other interested parties who wish to specify geothermal/ground source heat pump systems. The specification can be downloaded from the link below.

Standard Specification (Oct. 2018)

Part of the design process should include minimum requirements, which are outlined in the design and installation standards. Review the CSA/ANSI/IGSHPA C448 bi-national design and installation standards at the link below.

The pipe that is buried in the ground is crucial to the system’s life expectancy. Recently, PPI (Plastics Pipe Institute) provided an update to the model specification for plastic piping materials for ground source applications, which can be downloaded from the link below.

IGSHPA members working on U.S. government projects should download the technical specifications template to assist with project specifications and design guidance. Note that the specification references IGSHPA training and the CSA/ANSI/IGSHPA C448 Design and Installation Standard. IGSHPA members can purchase the standard at a discount (see link above).
