Public Review of ANSI/CSA/IGSHPA C448 Available
HRAI would like to inform its members that the next edition of the ANSI/CSA/IGSHPA C448 Design and Installation Standard for Ground Source Heat Pumps is ready for Public Review. IGSHPA has provided the latest updates to the standard and instructions to participate in the review process.
Since 1994 the IGSHPA Standards committee has continued to update the design and installation standards to provide the GSHP industry with the best guidelines for successful installations. The 2016 edition of the ANSI/CSA/IGSHPA C448 standard was the first bi-national (Canada-U.S.) standard; this next edition includes many updates as well as recommendations for changes to the bi-national standard from the IGSHPA Standards committee.
Following are some of the updates to the new C448 Standard:
• New piping materials added
• New heat transfer solutions added
• New section: Planning, design, installation, and commissioning of district energy systems
• New section: Design and installation of ground source heat pump systems connected to energy foundations
• New annex: Wastewater energy transfer systems design and installation
• Major updates to the design and installation of groundwater heat pump systems
• Major updates to the installation of standing column well heat pump systems
• Updates to all sections with the latest technology and applications
• Updates to definitions and terminology for consistency
Public Review will run through August 6, 2024.
