Presentations from the Final webinar June 13, 2022 – IEA HPT Annex 52 “Long-term performance monitoring of GSHP systems for commercial, institutional, and multi-family buildings” are now available at the HPT Annex 52 website under the tab “Documents”.
The key findings and deliverables from the Annex were presented together with examples from the many case studies. The work within HPT Annex 52 has led to a broad consensus on instrumentation, monitoring, and analysis of long-term performance, which, in turn, leads to further energy and cost savings.
Ground-Source Heat Pump (GSHP) systems for larger buildings provide renewable heating and cooling for a wide range of system applications. Long-term performance measurements from such systems are valuable tools for commissioning, fault detection, system optimization, and component development.
Within the four-year international collaboration project HPT Annex 52, more than 30 larger GSHP systems in seven countries have been monitored and altogether 119 years of measured performance data have been analyzed.
