This is a European project that forms part of the Horizon 2020 (H2020) Programme, a research and innovation programme launched and financed by the European Union for the period 2014-2020, aimed at applying a combination of technologies geared towards energy savings, reducing environmental impact and improving quality of life in Smart City environments. Its objective is to create a pilot scheme resulting in measures that can be replicated in other districts and cities in the future.
The cities chosen to lead the project are:
|12 solutions in the areas of building energy rehabilitation, the integration of urban infrastructures and sustainable urban mobility in a specific district.|
|Meeting the needs of the pillars: social, environmental and economic.|
The focus will be on the Sant Martí district:
Making it a Smart City.
|Rehabilitating over 20,000 m2 of buildings for residential and services sector use.
|Development of a global platform for the management of city infrastructures and data from different sources.|
|The goal is to improve and optimise traffic management, as well as implement infrastructure to foster vehicles running on alternative fuels.|
|Naturgy is working with a powerful consortium made up of 36 partners: local council authorities, professional associations, research centres, universities and companies.
|Different areas: energy, transport, telecommunications and more.|
|The team in Barcelona is led by the City Council of Barcelona.|
|The other project partners in Barcelona include Anteverti, BSC, Cenit, Endesa, I2CAT, IESE Business School, IREC, Retevisión, Schneider Electric and Urbis Up.|
|It also participates on some jobs with the Official Association of Architects of Catalonia (COAC).|
|It collaborates with the energy efficiency and renewable resources consulting firm Aiguasol.
First residential intake
Naturgy, a partner in the GrowSmarter Project in Spain, and the Agència de l’Habitatge de Catalunya (AHC), which is managing the renovation plan in the district of Canyelles, have reached a partnership agreement to undertake the full renovation based on passive criteria of a residential block in this district.
Actions to be taken as part of GrowSmarter include: improvements to the initially provided façade insulation, roof insulation, window replacement and shutter replacement. These measures will lead to increased insulation and protection from the elements for the building, thereby reducing the demand for climate control and increasing thermal comfort throughout the year, and a 44% savings compared to current total consumptions. It will also include measures to reduce water consumption (flow reducers) and energy consumption control and measurement (HEMS – Home Energy Management System) in all the properties.
Public-private partnership on GrowSmarter
The partnership process between the Agència de l’Habitatge de Catalunya and Naturgy has enabled the GrowSmarter Project subsidies to be officially compatible with the 2016 Financial Aid for Home and Building Renovation published by the Consorci de l’Habitatge de Barcelona.
Canyelles district redevelopment
Canyelles was built during the 1970s as a residential district in response to the large waves of migration. The Municipal Housing Board developed most of the building projects. For that reason, the public body agreed to the structural repair of the buildings in the agreement signed in 2007 between the City Council and the district’s residents’ association.
Objectives and benefitsThis project is a template model with regards to organising the sustainable cities of the future:
Reduction of emissions
Achieving the reduction of energy consumption and emissions by 60%.
Improved quality of life
Rehabilitation of buildings and improved transport of people and goods and in urban lighting .
Creating the equivalent of 1,500 jobs in all of Europe in the 2020 horizon.
1 October 2014: the proposal was approved by the European Commission. 2 The project will grant 25 million euros in subsidies for its development over a period of five years. 3 The environmental improvements will be made after an initial stage to select the participating buildings. 4 The operation stage will begin after the work has been finished. 5 Naturgy Servicios will be the energy service company (ESCO) responsible for said operation under an energy supply contract.
Naturgy participationNaturgy is taking part in the feasibility analysis, design, implementation and assessment of various energy efficiency improvement measures by providing the experience and know-how of various business units within the group.
The project is led by Innovación Tecnológica, in partnership with Naturgy Servicios, Naturgy Informática and Naturgy Engineering. Among others, the following measures will be implemented:
•Residential buildings Passive measures 1. Comprehensive rehabilitation of the covering on old buildings.
2. Reduction of solar gain in modern buildings.
Active efficiency improvement measures 1. Boiler replacement.
2. Water consumption reduction.
3. Connection to the “District Heating” network.
Implementation of home energy management systems (HEMS). 1. Improving energy efficiency.
2. Active participation by the user.
Rehabilitation is planned for homes 10,500 m2 Service sector buildings Active and passive improvements to hotels, public schools and sport centres. 1. Efficiency in heating facilities
2. Rehabilitation of enclosures and integration of renewable energies in some cases.
Implementation of building energy management systems BEMS Awareness campaign for students on energy savings. At the school Complete rehabilitation 12,500 m2
Residential and services sector buildings
Promote self-sufficient islands by installing renewable energies (photovoltaic). Demand reduction and energy efficiency measures. Maximising the use of any electricity generated by installing storage batteries. Creation of an IT platform to manage data from the project. A compressed natural gas (CNG) station will be installed to foster the use of alternative vehicles running on this fuel.
