Realising the Energy Efficiency and the Renewable Energy Potential Three conditions: • political will: political commitment • technical ability: committed & skilled technicians • people’s involvement: public participation PARTNERSHIP 23
Realising the EE and the RE Potential: the case of Barcelona (1) Barcelona, June 1995 - May 1999: • A committed group of people worked hard to open the door to the Energy Sustainability into the city • An interesting set of circunstances came together to make it happen: • municipality • RE Companies • RE NGOs 24
Realising the EE and the RE Potential: the case of Barcelona (2) • Municipality As a result of the 1995 municipal elections the city government adopted sustainability as a issue. April 22nd., 1998: the Plenary Session of the City Council adopted a political decision on Energy Sustainability, including: • promotion of energy efficiency, • use of renewable energies, • information to the citizens, • cooperation with other local energy actors. 25
Realising the EE and the RE Potential: the case of Barcelona (3) • To implement policies the municipality made use of two key instruments: • the Civic Table on Energy (‘Taula Cívica de l’Energia’) • the Local Energy Agency (‘BarnaGEL - Barcelona Grup de Energia Local’). 26
Realising the EE and the RE Potential: the case of Barcelona (4) • The Civic Table on Energy (municipal body) created in 1994 as a result of a public hearing on environment and energy involveslocal officials/stafffrom different departments of the city council with a localrepresentative of a NGO energy platform Barcelona Saves Energy (‘Barcelona Estalvia Energia - BEE’) main objective: to build complicitieson energy from all people in different departments of the city council. 27
Realising the EE and the RE Potential: the case of Barcelona (5) • The local Energy Agency BarnaGEL(independent) EU-PERU (now SAVE) project, 1994 Main proposers:Leicester City Council and Metropolitan Area of Barcelona Other local Partners:Ecoserveis (local NGO on energy & environment), ICAEN (Regional Energy Agency of Catalonia) and UAB (Autonomous University of Barcelona) Main objective: to build complicities between local actors in order to develop energy projects 28
Realising the EE and the RE Potential: the case of Barcelona (6) • The results of the work (1995 -1999) • doubling the solar th collector area • solar thermal: from 700 to 1,350 m2 • 29 times more solar PV collector area • solar PV: from 80 to 2,400 m2 • an EE&RE demo caravan • the Sustainable City Resources Centre • the Solar Law (Solar Ordinance) 29
Realising the EE and the RE Potential: the case of Barcelona (7) • The solar/wind/efficient caravan: Equipment being used in Barcelona city and around Barcelona province’s villages and cities to show in real operation how a house could run with renewables and energy efficient appliances 35
Realising the EE and the RE Potential: the case of Barcelona (8) • The Sustainable City Resources Centre: A municipal fixed facility equipped with a permanent exhibition with energy efficient devices and appliances and renewable energy devices. It’s open to the public, free of charge, since May 1999. 35
Realising the EE and the RE Potential: the case of Barcelona (9) • The Solar Law or the Barcelona Ordinanceon Application of Solar Thermal Energy Systems into the Buildings The Law enforces all the new buildings to be built in Barcelona (and all the integrally retrofitted buildings) to have Solar Thermal Water Systems to cover 60 % of sanitary water heating needs. Adopted by the Plenary Session of the Council (July 1999) Mandatory since 1st August 2000. 32
Realising the EE and the RE Potential: the case of Barcelona (10) • Solar Thermal Water Systems in all the existing municipal sports facilities. Two first installations completed: • Poliesportiu Torrent de Melis (74 m2 of solar collectors) • Piscina Bon Pastor (80 m2 of solar collectors). 33
Realising the EE and the RE Potential: the case of Barcelona (11) • A PV Solar Roof at the two main buildings of the City Hall EC Thermie Project 1,000 m2, 100 kWp 34
Realising the EE and the RE Potential: the case of Barcelona (12) • Efficient lighting systems at the City Hall Buildings: - replacement of all Incandescent Lamps in the City Hall buildings (October 1995) - replacement of all old fluorescent lighting systems in a main City Hall building -8 flats- (April 1998): savings of more than 250,000 kWh/year. 35
Realising the EE and the RE Potential: the case of Barcelona (13) • Biogas valorisation from organic fraction of wastes • Garraf Landfill • 3 Methanisation Plants (75,000 tn each) 36
Realising the RE Potential: the case of Barcelona (14) • All that have not been possible without a lot of complicities, ranging from companies to NGOs.
Realising the EE and the RE Potential: the case of Barcelona (15) • The future I hope that the work done until now will expand and in the next future we will see Barcelona city and its metropolitan area as a region where the Sun plays an important role as a energy source providing the required energy services (with end-use efficient technologies) for living lightly on the Earth.
