Pilot project in the area of improving the energy efficiency of public buildings implemented in the EPC/ESCO formula (with the participation of ESCO companies based on an energy efficiency improvement contract). The project aims to improve the energy efficiency of public buildings by supporting final acceptance in terms of, among others, heating of the facility, use of heat recovery technology, connection to the district heating network or in a limited gas scope, installation of new low-emission or renewable heat sources or electricity for own use, including home energy storage and heat pumps, replacement of lighting with more energy-efficient ones, devices enabling individual settlement of the costs of delivered heat or cold equipped with remote reading functions and the use of energy management systems in the building (BMS), as well as the modernisation of ventilation and air-conditioning systems. In terms of improving the energy efficiency of buildings, the minimum threshold for required primary energy savings, taking into account the scope of the project, is 30% (except for monuments). The scope of activities in relation to buildings, technical equipment or technological installations and processes must result from energy audits. For comprehensive projects, non-energy audit elements may also be supported if they pursue broader objectives of the European Green Deal, including the Renovation Wave strategy, such as increasing green space (green roofs, walls), developing electro-mobility, circular economy solutions, accessibility infrastructure, installation of energy storage and digitisation equipment for the building. Support for elements going beyond the energy audit will be possible up to 15% of the eligible costs of the project. The support model will take into account the grant element at the stage of implementation of the investment, supplemented by repayable support, taking into account the mechanisms of investment settlement and verification of effects. The amount of the grant component will depend on the level of energy savings achieved as a result of the implementation of the projects, as well as on the legal form of the final recipients of support. The NFOŚiGW, as the body implementing the IF in the field of EPC/ESCO, will provide support to the final recipients selected in the call/selections in the form of the IF in the field of EPC/ESCO. He will develop a programme dedicated to support the thermomodernization of public buildings in the ESCO/EPC model. The project will contribute to the implementation of the European Union's climate policy objectives set out in the European Green Deal, i.e. conducting actions aimed at combating climate change and reducing greenhouse gas emissions, which are a response to ongoing climate change and environmental degradation. In particular, it will contribute to the climate and energy directional objectives set out in the National Energy and Climate Plan 2021-2030 by financing investment projects leading to a reduction in greenhouse gas emissions, an increase in the share of RES in final energy consumption, an increase in energy efficiency by, inter alia, improving parameters related to the thermal permeability of building envelopes, increasing the efficiency of heat sources and installations, replacing lighting sources, installing energy management systems in buildings, etc., and reducing the share of coal in electricity production (photovoltaic installations). The project is of strategic importance as a pilot project on a national scale to increase the participation of private actors in the sector of thermal renovation of buildings, so that private EPC/ESCOs engage and invest in the renovation of public buildings to increase their energy efficiency.
