The ZA-GREEN Project is implemented by the City of Zagreb, City Office for Reconstruction, Development, Physical Planning, Construction and Utility Services, and with assistance of the project partner, the the North-West Croatia Regional Energy and Climate Agency (REGEA).
The total value of the ZA-GREEN project is EUR 2.7 million, of which the City of Zagreb contributes 10% from its own funds, while 90% is co-financing from the ELENA financial instrument, under the Horizon 2020 research and innovation programme.
The Contract for financing project development services, contract number: ELENA-2020-175, relating to the implementation of Project Development Services entitled “Zagreb’s Action for Green Reconstruction & Energy Efficiency Nurturing” (ZA-GREEN), in the framework of the ELENA facility, has been signed by the City of Zagreb and the European Investment Bank (EIB), following the Zagreb City Assembly's Resolution (Official Gazette of the City of Zagreb, No. 13/23), on April 21, 2023.
The implementation period for the ZA-GREEN project began on May 1, 2023, and lasts until April 30, 2026.
The ZA-GREEN project focuses on technical assistance for the development of main project designs and tender documentation for future investments in deep energy retrofits or comprehensive energy renovations of public buildings of the City of Zagreb.
By the ‘’Program of energy renovation of public sector buildings for the period until 2030’’ developed by the Ministry of Physical Planning, Construction and State Assets of Croatia, and adopted by the Government of the Republic of Croatia on March 31, 2022, definition of the types of energy retrofit projects:
Integral Energy Renovation
Generally refers to a set of improvements made to significantly enhance energy efficiency of the buildings. This type of renovation involves multiple coordinated energy-saving measures, with a focus on the building’s overall energy performance. In order to be qualified as ‘’Integral’’ the project has to achieve an energy savings of at least 50% (in annual heating energy demand, QH,nd) compared to the building’s pre-renovation consumption levels. In some cases integral energy renovation may include only one measure, such as enevelope insulation, in case the measure results in described level of energy savings.
Deep Renovation
Involves energy efficiency measures on the building envelope and technical systems, resulting in annual heating energy demand (QH,nd) and primary energy (Eprim) savings of at least 50% compared to the pre-renovation state.
Comprehensive Renovation
Covers optimal improvement measures for the current condition of the building and, in addition to integral and/or deep energy renovation, includes measures such as: i. enhancing fire safety, ii. ensuring healthy indoor climate conditions, and iii. enhancing the building’s mechanical resistance and stability, especially for improving earthquake resilience, and may also include other measures that improve the building's compliance with basic construction requirements.
