Special Issue Information

Dear colleagues,

Exploiting the ground as an energy resource offers many possibilities for efficient application to heating and cooling of residential and non-residential buildings. However, robust design methods for ground heat exchange systems and integrated heat pump systems remain a challenge. Effective design requires modelling heat transfer processes over a wide range of spatial and temporal scales in order to properly assess performance. We consequently invite articles that contribute to the advancement of modelling methods for ground heat exchange systems. Papers that are supported by experimental validation studies are particularly welcome.

The world-wide application of geothermal heating and cooling technologies continues to grow, and there are known to be more than four million ground source heat pump systems in operation. For this technology to make a significant impact on improving energy efficiency and reducing carbon emissions, there must be confidence in system performance levels in real operating conditions. It is consequently important that rigorous monitoring studies are made and openly reported. Accordingly, we invite articles reporting monitoring exercises concerning both ground heat exchangers and whole system operations from academic and industrial researchers as well as practitioners and system operators. Papers concerning non-residential systems are particularly welcome.

Topics of interest include:

  • Ground heat exchanger models;
  • Energy piles and diaphragm/screen wall models;
  • Monitoring and performance analysis of whole systems;
  • Model validation studies;
  • Monitoring methods and performance metrics;
  • Operational performance and fault detection;
  • Optimization of system performance and control.

When the new student center at Stockholm University in Sweden was completed in the fall of 2013 it was thoroughly instrumented. The 6300 m2 four-story building with offices, a restaurant, study lounges, and meeting rooms was designed to be energy efficient with a planned total energy use of 25 kWh/m2/year. Space heating and hot water are provided by a ground source heat pump (GSHP) system consisting of five 40 kW off-the-shelf water-to-water heat pumps connected to 20 boreholes in hard rock, drilled to a depth of 200 m. Space cooling is provided by direct cooling from the boreholes. This paper uses measured performance data from Studenthuset to calculate the actual thermal performance of the GSHP system during one of its early years of operation. Monthly system coefficients-of-performance and coefficients-of-performance for both heating and cooling operation are presented. In the first months of operation, several problems were corrected, leading to improved performance. This paper provides long-term measured system performance data from a recently installed GSHP system, shows how the various system components affect the performance, presents an uncertainty analysis, and describes how some unanticipated consequences of the design may be ameliorated. Seasonal performance factors (SPF) are evaluated based on the SEPEMO (“SEasonal PErformance factor and MOnitoring for heat pump systems”) boundary schema. For heating (“H”), SPFs of 3.7 ± 0.2 and 2.7 ± 0.13 were obtained for boundaries H2 and H3, respectively. For cooling (“C”), a C2 SPF of 27 ± 5 was obtained. Results are compared to measured performance data from 55 GSHP systems serving commercial buildings that are reported in the literature. Full article
