City of Zadar recognized the importance of sustainable development and is making an efforts in promoting the implementation of energy efficiency and renewable energy in the public sector as well as in private sector.

Its political will and commitment to the sustainable management City of Zadar expressed by signing several documents:

Energy CharterSigned in 2008.

This is a declaratory act of the local and regional governments in the Republic of Croatia, which shows awareness and political will to manage energy at the local level.

Covenant of Mayors

Signed in 2012

Signed in 23012European movement involving local and regional authorities, voluntarily committing to increasing energy efficiency and use of renewable energy sources on their territories. Signatories aim to meet and exceed the European Union 20% CO2 reduction objective by 2020.

Association of Energy Cities

European Association of local authorities in energy transition

Represents more than 1,000 towns and cities in 30 countries.

In 2012, Energy Cities initiated a process aimed at makingand debating proposals for accelerating the energy transitionof European cities and towns. These proposals are based oninnovative approaches, new ideas and groundbreakingpractices. They provide practical answers and link today’saction to the long-term vision of a low energy city with a highquality of life for all.

Participation in the project EU Cities Adapt

Zadar is one of 21 cities in Europe, which has been selected to participate in a project funded by the European Commission.

Objective: to provide capacity building and assistance to European cities to develop and implement strategies to adapt to climate change, to connect cities with similar problems and provide support (training, exchange of experiences, etc.) to develop a strategy to adapt to climate change, as the ultimate goal.

Working group on Climate Change, have been formed, includes all stakeholders.

Installation of solar system and gas installation in the Sport Centre Višnjik

96 vacuum tube collectors have been installed on the roof of the swimming pool for hot water preparation. Reconstruction of the existing boiler room which currently uses fuel oil for use of natural gas.

Annual savings : 636.000,00 kn

Expected reduction of CO2: 223 t

Public lighting

At 10 electric substations regulatory mechanism have been set. This mechanism reduces the voltage supply from 24.00 to 6.00 in the morning (from 220-240V to 190 V), thereby reducing the intensity of light.

Achieved savings in energy consumption 25%

Energy audits and energy certifications

Encouraging the citizens to implement energy efficiency projects

City announces public tenders:

•- installation of solar systems for water heating

•- termal insulation and installation of energy efficient windows

•- installation of stove on wood biomass

•- reconstruction of existing heating sistems on a sistem wich use gas in residential buildings

Project of gasification of the Dalmatia region

Currently, the project of gasification of Dalmatia region is underway

The gas distribution network will be built up in parts of the counties of Zadar (the cities of Zadar, Biograd na Moru and parts of the city of Benkovac), Šibenik-Knin (the cities of Sibenik, Drnis, Knin, Vodice, Bilice, Tribunj, Pirovac, Tisno and Murter-Kornati) and Split-Dalmatia (the cities of Split, Solin, Kaštela, Trogir and parts of the municipalities of Dugopolje, Klis and Segel)

It is planned to build up 1,450 kilometers of gas network in total which will usher gas to end users

In this way about 130,000 customers will be supplied by natural gas among which are a numerous public institutions, commercial and industrial enterprises and households

The total investment in this region reaches the total of approximately € 105 million

The introduction of natural gas in the headquarter ‘’Petrići’’

City of Zadar has started to encourage the reconstruction of existing heating sistems on a system which use natural gas in residential buildings (one pilot project is carried out, the headquarter ‘’Petrići’’)

Headquarter ‘’Petrići’’ includes 11 residential buildings with a total of 439 flats with 1,500 people. All buildings are heated by a central boiler that has two hot water boilers of individual power 3200 kW and heating fuel is the heavy fuel oil

Annual fuel consumption, depending on weather conditions is approximately 320,000 kg of heavy fuel oil

The total value of investment is 119,000 euros (City of Zadar will co-finance 13,157,9 euros, Environmental Protection and Energy Efficiency Fund 52,631,6 euros and the rest will be co-financed by tentants)

Investment return is approx. 1 year

Greetings to the Sun

• The project objective is to continuously monitor energy consumption in public buildings.

• Register of all buildings owned by the City of Zadar with all the details : building area, year of construction / reconstruction, contacts, energy consumption (fuel, electricity, water) energy certificates, monthly bills, all the changes on the building or heating system that have been undertaken ect.

• The database contains information on the energy consumption from 2007 until today and beyond

Sustainable energy action plan SEAP

SEAP is composed of 2 parts:

1.The analisys of energy consuption and the basic inventory of CO2 emissions - building sector - sector of public lighting - traffic sector

2.Action plan - Defines measures for reducing CO2 emissions - Organization of implementation, monitoring implementation, reporting, - Defines human sources and financing resources
