Piping Updates to CSA/ANSI/IGSHPA C448 and Projected Design Life of Ground Heat Exchangers
Presented by: Lance MacNevin, P.Eng., The Plastics Pipe Institute (PPI)
Lance MacNevin, a member of the CSA C448 Technical Committee, walks through what changed for piping in the 2025 edition of CSA/ANSI/IGSHPA C448 and what the latest guidance says about how long ground loops last.
What you'll learn:
- More stringent requirements for HDPE pipe, plus the addition of PE-RT materials
- New requirements for installing and pressure testing ground heat exchangers
- Highlights from the newly released PPI Statement AF, “Projected Design Life of Plastic Piping Used in Ground Heat Exchangers,” covering design life and service life of GHX piping
- PPI resources available to support the GSHP industry
About the presenter: Lance is senior director of engineering for PPI's Building & Construction Division and has worked in the plastic pipe industry since 1993. He is an active member of ASHRAE, ASTM, CSA, IGSHPA, and other codes and standards bodies.

Oak Ridge National Laboratory – Analysis Results Review
Join us for a detailed review of recent analysis results completed in collaboration with Lawrence Berkeley National Laboratory and the National Renewable Energy Laboratory. Building upon the landmark 2023 geothermal impact study, this research demonstrates how ground-source and geothermal heat pumps function as critical assets for the electrical grid.
Speakers & Agenda:
Introduction & Policy Review: Ryan Dougherty, President, GeoExchange
Research Presentation: Dr. Xiaobing Liu, Distinguished R&D Staff, Oak Ridge National Laboratory
