Pilots & Roadmaps


The roadmaps will be tailor-made to the characteristics of the building stock, the characteristics of the vulnerable households and the climate conditions, to cover a sufficiently cohesive group of cases that will allow for a larger- scale rollout and replication of the proposed actions for the effective analysis and tackling of the problem. The roadmaps will target the worst-performing homes first (“worst first” principle), will cope with split-incentive dilemmas and will address market, information and behavioural failures through the creation of “one-stop shops” (OSS) in 4 countries as defaults for the enrolment of vulnerable households in subsidised energy efficiency improvement programmes for buildings.

An end to energy poverty would see an increase in well-being and physical health, less money spent by governments on healthcare, reduction in air pollution, improved household budgets and increased economic activity.

4 pilots

The roadmaps developed during the project will be tested in 4 different pilots – Bulgaria, Greece, Latvia and Portugal. The four pilots are chosen to represent different climate conditions, building types and conditions, among other factors that are very different in these countries. 

REVERTER 4 pilot countries

Riga, Latvia

Brezovo, Bulgaria

Athens Urban area, Greece

Coimbra, Portugal 

REVERTER project


The Municipality of Brezovo has elaborated its Energy Efficiency plan, where it has set an ambitious goal to achieve a complete renovation of at least 30% of the used dwellings by 2025. To do so, it has to influence the renovation of approximately 810 dwellings.

REVERTER project

Athens Urban area, Greece

9.7% of the Pilot Area households were energy-poor. Based on the subjective indicators, 21.9% reported “Leaky roof, damp walls, floors, foundations or rotten windows”, 21.6% reported “Inability to keep the house sufficiently warm” and 24.6% declared “Arrears in bills”.

REVERTER project


In Riga city, almost 85% of inhabitants live in multi-apartment buildings out of which 94% own their apartment. Around 6,000 multi-apartment buildings, which cover almost 75% of the total floor space, were built during the post-war period with poor insulation.

REVERTER project


Recognising that social housing residential buildings is a special case, the REVERTER project will develop and test a dedicated roadmap for social houses. The Coimbra Municipal Housing Park (social housing) consists of 854 dwellings, with different typologies.
