A NECESSITY FOR THE EU RENOVATION WAVE?

The European Commission launched the European Green Deal in 20191 to address the climate challenge, with an integrated policy package covering a range of sectors. For the built environment, the Renovation Wave2 aims to accelerate improvement of the energy performance of 35 million buildings by 2030.

To achieve this, much emphasis is put on advancing technology integration by developing integrated and compatible technology packages for building renovations. However, a technology perspective alone is not enough. A good practice assessment3 performed by the EU funded RES4BUILD project on Integrated Energy Solutions (IES) reveals that accelerating the uptake of IES increasingly requires consideration of financial and social innovation to address non-technological barriers.

It was found that a robust IES solution needs solid technologies which become affordable thanks to accompanying financing and warranty plans (e.g. building-linked finance, lease/rent/subscription-based finance, energy performance contracting), and socially realistic with help of end-user engagement procedures and communication protocols before, during and after the renovation.

Barriers to implement and scale IES
D'oca, et al. (2018)4 conclude that, "Until now, deep renovation has often been approached as a technological challenge" while "social and financial barriers have been overlooked". They suggest that "new approaches will probably need to integrate technical, financial, and social aspects from the beginning […]." Both literature and market experience offer insights on technical, financial, and social barriers to the upscaling of individual technologies (e.g. heat pump, solar PVT) and IES concepts in the built environment, as well as ways to overcome these barriers.

Integrated Energy Solutions 2.0
An IES solution should thus be more than a turn-key technology package composed of a mixture of energy installation, insulation, and IT controller technologies. The RES4BUILD assessment highlights good practices in Poland and the Netherlands, and explores key elements of a robust, marketable, and scalable IES (Fig. 1).

Based on this assessment, a robust IES should:

  • Be an integrated turn-key technology package that offers a guaranteed energy performance (performance contract); where a smart ICT system monitors i) the energy system and ii) end-user behavior, and where there are clear and simple lines for communication and engagement with stakeholders / end-users available before, during and after renovation.
  • Provide innovative fi nance solutions to be developed and offered jointly with an IES technology concept to allow for multi-stakeholder, collective or group finance that is sufficiently flexible to meet specific end-user needs and limitations (e.g. building-linked finance, rent/lease/subscription finance packages, hybrid finance).
  • Ensure early involvement of end-users in the IES implementation process to improve acceptance and faster implementation of IES by establishing collaborations with new social structures, like local citizen initiatives, homeowner associations, and energy cooperatives.
