In Brussels, Belgium, a joint workshop of IAs ECBCS and the HPP, took place, where some of the Annexes of the two IAs have been presented. One of these Annexes was Annex 29 Ground Source Heat Pumps – Overcoming Market and Technical Barriers, and it has been demonstrated, what a variety of different solutions using the ground as heat source/heat sink or as a store can achieve highly efficient and environmentally friendly solutions for heating and cooling buildings.
November 1-2, 2007
In Beijing, P. R. China, an IEA NEET Workshop took place. One of the few presentations on end-use energy technologies was a session on heat pumps. While the presentation of the HPP covered globally the development of heat pump components, units and systems – one topic were ground source heat pumps, the presentations from China by Prof. XU Wei, Director, Institute of Air Conditioning, China Academy of Building Research and Mr. CONG Xuri, Chairman of the Hundred Group, were concentrated on applications and installations of ground source heat pumps in China.
August 21-26, 2007
In Beijing, P. R. China, the 22nd IIR International Congress of Refrigeration - Refrigeration Creates the Future, ground source heat pumps also played an important role, both in the oral and in the poster presentations. A technical tour went to a large ground source heat pump installation suitable for both heating and cooling using 700 boreholes with a depth of 100 m equipped with double u-tube coils.
January 15-17, 2007
In Sapporo, Japan, a workshop and a working meeting of Annex 29 took place. The event has been organised by Prof. Katsunori Nagano, Hokkaido University and his team and Dr. Li, Heat pump technology and thermal storage center of Japan, and it became an excellent meeting. On January 15 a workshop took place at the Conference Hall of Hokkaido University, Sapporo, with interesting presentations of the participants in this Annex from Canada, Japan, Sweden and Austria as well as experts from all over Japan and guests from China. A technical visit covered a snow melting pavement with GSHP at Faculty of Agriculture of Hokkaido University.
On January 16 site visits took place, the participants saw a GSHP demonstration installation at the Tondenkita Public Junior High School, snow melting systems, and GSHP installations at the Hokkaido Electric Meter Industry Co., Inc. and at the Sapporo City University. In the late afternoon there was the possibility for a walk around Jigokudani (the hell valley), a volcanic site, in the evening there was a dinner in the Noboribetsu Grand Hotel, where on January 17 the working meeting of Annex 29 took place.
Decisions were taken on the further steps of the working plan.The final site visit in the afternoon was to a very nice and well designed low energy house in the Naganuma town with a ground source heat pump, a ground air collector for pre-heating and pre-cooling the ventilation air and a CO2 heat pump water heater.
November 15-17, 2006
The 9. Geothermische Fachtagung in Karlsruhe, Germany, combined with the 6th Symposium on Ground Source Heat pumps, which was organised by Burkhard Sanner, was the platform for a presentation of Annex 29 by Hermann Halozan.
Another participant in Annex 29, Goran Hellstrom, gave interesting presentations on ground source heat pumps in Sweden and on the thermal response test, an important tool for designing large systems. This meeting showed again the importance of ground source heat pump systems.
May 18/19, 2006
At the Executive Committee Meeting in Tokyo, May 18 – 19, 2006, the Operating Agent asked due to a delay in the working plan the Executive Committee for an extension of Annex 29 until the spring meeting 2007 of the committee. Sweden asked for an extension to the fall meeting 2007, and the delegates proposed finishing the Annex with the fall meeting and presenting the results of Annex 29 at the IIR Congress in Beijing, China, August 21 – 26, 2007. The next working meeting of the Annex 29 will take place in Sapporo, Japan, in January 2007.
May 11/12, 2006
On May 11 – 12, 2006, in Linz, Upper Austria, a workshop and a working meeting of Annex 29 took place. In the workshop the representatives of the participating countries Canada, Japan, Norway, Sweden, the United States of America, and Austria as well as participants from Austria representing the European Heat Pump Association EHPA, the Association of the Electric Utilities VEOe, the Heat Pump Association LGWA, the Heat Pump Manufacturers Association BWP gave presentations on the international and national situation of ground source heat pumps. An interesting topic was the Austrian klima:aktiv programme with the goal to improve the market share of highly efficient heat pumps in Austria. In the afternoon a visit of the heat pump manufacturer NeuraTherm in Regau, specialised on direct expansion ground source heat pumps using propane as refrigerant, took place.

Starting date was January 1st, 2004, the end was planned with June 30th, 2006. Seven countries have decided to join, i.e. Canada, Japan, Norway, Spain, Sweden, the United States of America, and Austria as Operating Agent.
September 13/14, 2003
The topic ground source heat pumps has been discussed at several meetings of the Executive Committee of the IEA Heat Pump Programme. Within the framework of the IEA Heat Pump Programme three Annexes on ground coupled heat pumps have been carried out, Annex 2: Vertical Earth Heat Pump Systems, Annex 8: Advanced in-ground Heat Exchange Technology for Heat Pump Systems, and Annex 15: Heat Pump Systems with Direct Expansion Ground Coils; the Energy Conservation through Energy Storage Implementing Agreement has carried out Annex 13: Design, Construction and Maintenance of UTES Wells and Boreholes. Many countries showed interest, but the final decision was missing. To overcome this situation an expert meeting was initiated by Austria. It took place at the facilities of arsenal research in Vienna, 10 counties expressed their interest and 7 countries - Canada, Germany, Slovakia, Spain, Sweden, Switzerland, and Austria attended this meeting, apologies came from China, Japan, and Netherlands.
