Why & How


This section is about IMPULSE PLUS that started in March 2021

One key objective towards the 2050 long-term decarbonisation strategy included in the Climate Target Plan 2030 is energy renovation of public buildings (ERB). In this line, several instruments have been set by the directives under the Clean Energy for All Europeans Package. Also, the Covenant of Mayors sets common guidelines for local authorities to develop their Sustainable Energy (and Climate) Action Plans (SECAPs) including specific energy/cost indicators for Municipal buildings.

However, the weighted annual energy renovation rate is low at some 1%. The main common territorial challenge tackled by IMPULSE is insufficient capacities of local public administrations to manage integrated, reliable, and cost-effective ERB action plans for their buildings’ stock, responding to the EU Directives and ensuring reliable completion of SECAPs.

IMPULSE’s financial scheme evaluation tool for gradual building energy renovation and planning, including the decision-making support tool PLUG-IN KPIs-processor for automated hierarchy of public buildings, aims to address such challenges. Transferring IMPULSE’s selected outputs shall contribute to kick-start EU renovation wave, in both the climate neutrality and the postCOVID19 economic recovery dimension, while ensuring that current legislation and policies relevant to the European Green Deal are enforced and effectively implemented. 


This section is about IMPULSE that was implemented from November 2016 to July 2019

“Cost optimal pathways for energy renovation of public buildings to become a reality”

The recast EPBD (2010/31/EU) and EED (2012/27/EU) pose demanding requirements for Member States for the energy renovation of public buildings (ERB): 

Targets in national plans for stimulating buildings’ refurbishment towards Nearly Zero Energy Buildings set annual 3% renovation rate for central government buildings or lower administrative levels

The Covenant of Mayors sets common guidelines for local authorities to develop their Sustainable Energy Action Plans (SEAPs) including specific energy/cost indicators for Municipal buildings

At the same time, local public administrations experience very low rates of energy upgrading projects planning and implementing, mainly due to the following reasons:

Difficulty in data collection for public buildings and in completing SEAPs indicators 

Missing protocols and methods for public buildings bundling and for decision making towards large-scale Building Energy Renovation (ERB) Projects

Limited budget and/or insufficient capacity to attract funding for implementing ERB projects 

IMPULSE aims to address all the above challenges through a transnational collaboration among scientific (energy agencies) and institutional (municipalities) partners, aiming at pilot testing of protocols and methods for public buildings classification and energy analysis towards an integrated management support system for planning public buildings ERB projects. More specifically, testing activities take place in six strategically selected pilot cities in the Mediterranean, capturing the majority of Mediterranean climate zones and building construction profiles. These testing activities involve the following:

Municipal buildings classification into representative typologies 

Estimation of energy performance indicators towards energy consumption profiles of the municipal building stock for several combinations of energy upgrading measures

Techno-economical analysis to identify cost-optimal roadmaps for gradual energy renovation 

Integration of results into an online platform to easily identify cost optimal pathways for energy renovation of buildings
