The project LIGAR - Energia para todos! [Energy Efficiency for All!] was promoted by the National Energy Agency of Portugal (ADENE) and counted with the participation of entities with diverse backgrounds: CENSE FCT-NOVA, Institute for Social Sciences of the University of Lisbon (ICS), Sair da Casca (consultancy company in sustainability and social responsibility), and CDI Portugal (non-governmental organisation for inclusion and innovation).The project adopted an inclusive approach for implementing consumer engagement actions to increase energy efficiency in vulnerable homes and reduce energy poverty, aiming to foster behavior change and contribute to the reduction of energy poverty vulnerability of citizens.

In the project's first phase, CENSE developed a multidimensional high-resolution Energy Poverty Vulnerability Index (EPVI) to assess energy poverty vulnerability in all 3092 Portuguese civil parishes (local administrative units smaller than municipality), aiming to identify and map hotspots of vulnerability in winter and summer. Tencivil parishes from mainland Portugal were selected for the next phase of the project, according to their higher vulnerability levels in summer and winter, territorial typology (rural/urban), size of the population, and easiness in accessibility and communication with local authorities, which were regarded as important intermediaries to engage with the population.

In the second phase of the project, ICS devised a methodology to qualitatively study the population, or audience, of the selected regions in what pertains to the circumstances conducive to a situation of energy poverty and its impact on well-being and daily life. The goal was to identify opportunities for interventions and to develop energy poverty alleviation strategies.

In the third phase of the project, ADENE, Sair da Casca and CDI Portugal developed various initiatives to engage the local community and tackle the identified causes of vulnerability:
Development of an energy efficiency manual for local agents and the wider population, addressing all the areas about which a lack of information was identified.
An ideation contest was also implemented in the selected regions, aiming to promote innovative ideas to stimulate awareness and involvement of local agents for energy efficiency whilst guaranteeing execution and continuity.
Energy brigades were organised, where trained local groups personally supported vulnerable households to use energy more efficiently.
