Award-winning project Refurbishing ‘Los Limoneros’

Malaga, Spain

Los Limoneros is a social housing complex, which thanks to the project has significantly improved its energy rating.

From 2011 to 2014, the city of Malaga carried out the ‘energy efficiency refurbishment through participation' project  to help reduce energy consumption in Los Limoneros. Many residents living in this deprived neighbourhood were primarily opposed to energy efficiency measures, being afraid that it would increase their rents.

Council staff members, acting as liaison officers in the neighbourhood, helped building trust with the residents. From the beginning, the community has been actively involved in the process, and residents could engage in the "Pilot Project Participative Group" to discuss the measures. As a result of these discussions, the city drew up and implemented a detailed energy efficiency plan. An awareness raising campaign and a smart metering campaign helped sharing the message.

Involving the local community in the decision-making process has been a key success factor for the project. City staff managed to really engage with citizens and gain their trust. Throughout the process, the community has developed a sense of ownership and residents could learn new skills.

Background and objectives

In the past, attempts to deliver energy efficiency measures in Los Limoneros, such as improving the window insulation, had encountered problems. Without properly engaging residents in the process, they resulted in sabotage and vandalism. As an area that is known for high unemployment, crime, drugs, poverty and illegal activity, energy efficiency was not a top priority for residents. Many were also afraid that such measures would lead to an increase in their rent. The ‘energy efficiency refurbishment through participation’ project, completed in May 2014, was different. It sought to build trust with residents and actively involve them in the process from day one.


The city allocated a specific member of staff to act as a liaison for the project. This allowed the project team to build lasting relationships with the residents and generate mutual respect.

There were two main channels within the participatory process:

The Territorial Management Group (TMG), made up of energy efficiency experts, engineers and architects, tasked with assessing the building’s energy performance and identifying potential improvements.

The Pilot Project Participative Group (PPCG), gathering residents affected by the refurbishment. The city held regular meetings with between 10 and 45 residents each time.

Council staff and property owners attended both groups. Any solutions devised in the TMG were taken to the PPCG for discussion with residents. As a result of these discussions, the city drew up and implemented a detailed energyefficiency plan. Measures included a solar thermal and cogeneration heating system for sanitary water, insulation of the roof and crawl space, thermal wall insulation, and ventilation of the central patio by opening the skylight. Residents have since been invited to workshops on the heating system and how to maintain it.

The project in Los Limoneros was complemented by two broader initiatives: an awareness raising campaign, and a smart metering campaign. These targeted a number of different neighbourhoods and informed residents about how to save energy and reduce costs.

The awareness raising campaign included using soluble graffiti to spread energy efficiency messages and engage young people; distributing information and giving expert advice; and the use of a cartoon character, the lightbulb ‘Gastón’, as a creative way of sharing the message. This campaign reached 14,439 people directly and a further 23,102 indirectly.

The smart metering campaign involved installing 45 smart meters in social housing in various neighbourhoods, including 20 meters in Los Limoneros. This allows residents to directly monitor their consumption, and identify when and how they are using energy. Council staff meet regularly with residents to advise them on reducing consumption and saving money, and many have already noticed a difference.

Financing and resources

Los Limoneros was a pilot project carried out under the ELIH MED (Energy Efficiency in Low Income Housing in the Mediterranean) project, and was 75% funded under the European Regional Development Fund (ERDF). The remaining 25% was made up of local funds.

Results and impacts

The initial survey sent to residents on comfort and energy consumption had a 20% response rate. This might not sound like much, but for a community previously so opposed to energy efficiency refurbishment, it showed a growing change in attitude. Four of the residents were even hired to work on the project.

Workshops on the heating system and its maintenance have helped creating a sense of ownership among residents - reducing the risk of vandalism - and let them learn new skills.

Lessons learned and transferability

Gaining the trust of residents was the biggest success factor in the Los Limoneros energy refurbishment programme.

Sandra Marín Herbert from the Malaga City Council explains: "Engaging the local community has been key to the success of the ELIH MED project. Too often the residents are merely informed of decisions that have already been made. ELIH MED gave us the opportunity to involve these residents in these decisions that directly affect their quality of life."

City staff managed to really engage with citizens through this project. They were surprised by how effective this new way of working could be. By managing to get the president of the residents’ association on side, for example, they were able to gain the trust of many others. The project proved that by connecting with people on a personal level and gaining their trust, a lot can be achieved.

Malaga is keen to build on the success of this approach. It continues to engage residents through workshops and has recently gathered local graffiti artists to paint a mural on the building’s northern facade to promote the energy efficiency message. This was also carried out with the involvement of residents, and forms part of a wider plan that will be implemented together with the Municipal Housing Institute (IMV) to improve the area around Los Limoneros, creating extra services and amenities to make it a nicer place to live.
