The IEA provides support for international collaboration on energy technology R&D, deployment and information dissemination. These groups function within a framework created by the IEA - the International Framework for International Energy Technology Collaboration. The views, findings and publications of these international groups (formally called Implementing Agreements) do not necessarily represent the views or policies of the IEA Secretariat or of all its individual member countries. OECD Member countries, autonomous OECD non-member countries, intergovernmental organisations, non-governmental organisations and private sector entities may participate. For more information, see our Technology Agreements page.

Heat Pumping Technologies

The HPT IA, created in 1978, conducts high-level international collaborative research and dissemination activities. These are aimed to highlight the environmental and energy-conservation benefits of heat pumping technologies, support policy in order to increase the deployment of appropriate heat pump technologies, promote international collaboration, and position heat pumping technologies higher on the political agenda. The HPT IA membership is committed to provide the necessary information to develop industry standards, to continue to improve efficiencies, and to remove barriers to wider deployment of heat pumps.

Current Projects (Annexes)

34. Thermally Driven Heat Pumps for Heating and Cooling
The goal of Annex 34 is to reduce the environmental impact of heating and cooling by the use of thermally driven heat pumps. The economic, environmental and energy performance of integrated thermally driven heat pumps in cooling and heating systems in a range of climates, countries and applications will be quantified. From this, those areas and applications with the greatest environmental benefit, the best economics and the greatest market potential will be identified.


35. Application of Industrial Heat Pumps
The objective of this Annex is to reduce the use of energy and emissions of greenhouse gas emissions by the increased application of heat mumps in industry.


36. Quality Installation and Maintenance
The desired end-product objectives are: - develop information for use by key stakeholders in industry (HVAC-R and construction trades), government (policy makers), and building sector (owners/operators). - produce reliable data to position each Annex participating country to evaluate its pertinent industry standards and practices for the heat pump system types of primary interest to ensure optimum heat mump performance - reduce usage of energy and emissions of greenhouse gases by encouraging use of quality heat pump installation and maintenance practices.


37. Demonstration of field measurements on heat pump systems in buildings - good examples with modern technology
The overall aim of this Annex is to demonstrate the potential with heat pumping technology for all types of buildings from all ready performed field measurements. The focus will be on the best available technique. The project will: - Demonstrate and disseminate the economic, energy, environmental potential with heat pumping technology. Calculate the electricity consumption and energy savings, compared to alternative ways of heating - Improve the understanding of key parameters influencing the reliability and efficiency of heat pump systems - Develop a database from already performed field measurements presented using a common method to express such as seasonal efficiency and energy savings.


38. Systems Using Solar Thermal Energy in Combustion with Heat Pumps
The aim is to analyse solar and heat pump configurations with respect to energy savings and total cost of ownership (TCO) for investment and operation. The Annex is a joint Annex with IEA Solar Heating and Cooling.


39. A Common Method for Testing and Rating of Residential HP and AC annual/seasonal Performance
In this Annex, the following will be developed: - Common calculation methods for SPF using a generalized and transparent approach, based on lab measured data. - Establish comprehensive test methods based on further development of existing test standards. The test standards should include test conditions needed for the future SPF calculations. - A method to evaluate additional heat pump performance, e.g. Carbon Footprint, Primary Energy Saving or Energy Savings.


40. Heat Pump Concepts for Nearly Zero Energy Buildings
This Annex will examine: 1) Optimisation of concepts for buildings in order to reach Nearly Zero Energy consumption applying heat pumps as core component of the building technology 2) Evaluation of building- and system integration options favorable for the application in Nearly Zero Energy Buildings 3) Requirements for further developments of current marketable heat pumps to exploit specific performance opportunities in Nearly Zero Energy Buildings (e.g. multi-source ability, capacity range, capacity control, temperature lift)


41. Cold Climate Heat Pumps (Improving low ambient temperature performance of Air-Source Heat Pumps)
The aim of this annex is to Identify technology solutions leading to successful (efficient & reliable) systems/equipment for residential and small commercial buildings in cold climate locations with primary focus on air-source heat pumps.
