The main objective of the project (at the result level) is to move the Karol Marcinkowski University Hospital in Zielona Góra Sp. z o.o. to a low carbon economy through the use of renewable energy sources. The main objective will be achieved through the achievement of the direct objective of the deep thermal modernisation of the Hospital’s facilities in accordance with Article 5. 1 of Directive 2012/27/EU on energy efficiency. The implementation of the investment at product level will not only allow for a deep thermal modernisation of public buildings, but also for: 1. minimising energy consumption; 2. Increasing the standard of medical care buildings; 3. obtaining the effect of thermal comfort; 4. Increasing thermal safety in health care buildings. In the longer term, the implementation of the project will therefore contribute to improving the energy efficiency of buildings in the health sector and reducing the overload of the atmosphere by negative combustion products and reducing energy pressure on the environment. The long-term effects (at the level of impact) of the project include: — Increased energy efficiency of buildings in the public sector; — Improving the image of health care; — Improving the energy efficiency of the facility; — Increasing the quality of health care infrastructure in Zielona Góra and in the area of ZIT Zielona Góra; — The transition to a low-carbon economy through the use of renewable energy sources and increasing energy efficiency in Zielona Góra and ZIT Zielona Góra; — Increasing competitiveness of the Hospital in Zielona Góra in the region, in the western part of Poland. The project is therefore directly part of Priority Axis 3's main objective, i.e. the transition to a low carbon economy through the use of renewable energy sources and increasing energy efficiency.
