Working together to ensure reliable, affordable and clean energy
ETI banner Energy technology initiatives

The IEA supports international energy technology research, development, deployment, and knowledge transfer through multilateral groups (formally called Implementing Agreements). The experts participating in the activities of the Implementing Agreements represent public and private sector entities worldwide. Together, these experts share knowledge – and resources – to advance energy technologies.


Heat Pumping Technologies

Heat pumps are an efficient way to cover all building energy needs, including dehumidification.*

Multifunctional heating and cooling 

Policy context
By using the heat in the air, earth and water, heat pumps have the potential to significantly reduce consumption of fossil fuels and CO2 emissions. Recent policies enacted in Europe, Japan, and the United States aim to reduce carbon dioxide (CO2) emissions through accelerated deployment of clean technologies including heat pumps. These strategies will play an important role in reducing barriers to deployment. 

Background
The aims of the Implementing Agreement for a Programme of Research and Development on Heat Pumping Technologies (HPT IA) are to quantify and publicise the energy saving potential and environmental benefits (local and global) of heat pumping technologies; develop and deliver information to support deployment of appropriate HP technologies; promote and foster international collaboration to develop knowledge, systems and practices in HP technologies through further research, development, demonstration and deployment; provide an effective flow of information among stakeholders and other relevant entities; and significantly improve the visibility and status of the Programme. There are currently 14 Contracting Parties.

Spotlight
Low-energy houses are now integrated into current building practice and represent a growing share of new home designs. Integrating multifunctional heat pump concepts into low-energy house designs is an efficient way to treat several building functions simultaneously. Despite having been introduced to the market, the market share for heat pumps remains low. As a result, data from operational experiences are rare.

One recent HPT IA project, Economical Heating and Cooling Systems for Low-Energy Houses, brought to light new information on the cost-efficiency of heat pump concepts in low-energy houses.

Seven multifunctional heat pump prototypes were developed, lab tested, and field proven in countries participating in the study1. Best practices in systems design were identified, leading to industry recommendations. 

Some of the heat pump concepts developed within the project proved to be so efficient that they are now commercially available in North America. More of the developed prototypes are currently being field-tested. The results of this study are summarised in best-practice sheets, systems concept sheets, and a final report (executive summary, market overview, systems developed, and field monitoring).
