Promising outlook for an integrated approach to heat pumps

The installation of heat pumps into existing buildings in the Netherlands can contribute to the energy efficiency and renewable energy objectives of the Energy Agreement.  However, researchers from Utrecht University conclude that the implementation of heat pumps is only really effective when the agreement is fully addressed.

Zero Energy

Ten years ago it was not commonplace for heat pumps to be used in new constructions or in existing buildings. Heat pumps have since become one of the key zero-energy (i.e., no energy costs) technologies for renovation projects. Additionally, the heat pumps fit into the conventional renovation model where energy labels are assigned.

300,000 additional heat pumps

Researchers at the Copernicus Institute of Sustainable Development at Utrecht University investigated what measures can contribute to the realisation of 300,000 extra heat pumps in 2020. This was completed in collaboration with the Dutch Heat Pump Association and BDH under the Cooperation Top Sector Energy and Society (TKI STEM) program.

Dominant position

According to the researchers, the success of the heat pump greatly depends on the renovation technique. Dr. Robert Harmsen of the Copernicus Institute explains: "Because a heat pump produces the highest yield in extensive insulation measures combined with low temperature heating, the technology dominates current zero-energy renovations, in contrast to the application of heat pumps in conventional refurbishments.

Feasibility in a fix

Although a great success, this method will only produce 150,000 additional heat pump installations in 2020. To achieve the goal of 300,000 heat pumps in 2020, a substantial contribution from traditional renovation chains is necessary. While there is high potential for heat pump installations in the traditional renovation process, strong competition and resistance among other parties who continue to promote the boiler, is placing the feasibility of the installation goal in a fix.

A systematic approach is crucial

The research shows that an integrated approach is necessary in order to achieve the objective of zero-energy renovations and refurbishments. Clearly labelled steps are necessary. In the report, the researchers suggest that both renovation processes take measures to accelerate the renovation of houses and the application of heat within them. These conscious measures form an integral package. For the success of the heat pump system, a crucial approach is needed.
