HPT TCP ANNEXES ANNEX 52 LONG-TERM MEASUREMENTS OF GSHP SYSTEMS PERFORMANCE IN COMMERCIAL, INSTITUTIONAL AND MULTI-FAMILY BUILDINGS Introduction HPT Annex 52 – Long-term performance monitoring of GSHP systems for commercial, institutional and multi- family buildings, has now reached its midway point. Seven countries are participating in the annex (Sweden, USA, Finland, Norway, Germany, UK and Netherlands). The seven participants are contributing 40 case stu- dies of long-term monitored GSHP systems, all serving commercial, institutional or multi-family buildings with heating and/or cooling systems of varying degrees of complexity. The outcomes from this annex will help building owners, designers and technicians to evaluate, compare and optimize GSHP systems. It will also provide useful gui- dance to manufacturers of instrumentation and GSHP system components, and developers of tools for monito- ring, controlling and fault detection/ diagnosis. This will lead to energy and cost savings. To date, outcomes of the annex include a bibliography with published long-term performance analyses of lar- ger GSHP systems, four published journal papers on three case studies included in Annex 52, and four confe- rence papers. Open source measurement data are avai- lable for two of the published case studies. Objectives » Survey and create a library of quality long-term mea- surements of GSHP system performance for commer- cial, institutional and multi-family buildings. All types of ground sources (rock, soil, groundwater, surface water) are included in the scope. » Refine and extend current methodology to better characterize GSHP system performance serving com- mercial, institutional and multi-family buildings with the full range of features shown on the market, and to provide a set of benchmarks for comparisons of such GSHP systems around the world. » Compile guidelines documents for instrumentation, data collection, analysis and reporting of key perfor- mance indicators for large GSHP systems. Progress The first objective of Annex 52 has been to compile an annotated bibliography of long-term performance monitoring of larger GSHP systems. This bibliography now contains over 70 publications describing some 60 buildings where long-term performance monitoring of larger GSHP systems have been performed and that contain some form of SPF measurement. Spitler and Gehlin (2019) present a comprehensive review of the performance measurement literature for large GSHP systems. The review made clear that nomenclature for performance indicators used by different authors is inconsistent, reflecting a lack of consensus on how to evaluate, express and present performance for complex large-scale GSHP systems.
