It was designed to replace the old wooden joinery with new five-chamber PVC windows with a heat transfer coefficient of Uw=0.9 W/m2K. Carpentry replacement area: 10,92 m2 (2 pcs.) In addition, additional works will be carried out, including: new interior and exterior window sills, installation of blinds and stained glass, installation of diffusers controlled automatically on all windows. • The replacement of PVC joinery with new five-chamber PVC windows with automatically controlled ventilators with a heat transfer coefficient Uw=0.9 W/m2K has been designed. Carpentry replacement area: 171.0m2 (84 pcs.) In addition, additional works will be carried out, including: new internal and external window sills, installation of diffusers controlled automatically on all windows. 2. Door joinery: It was designed to replace the old door joinery with a new door with a heat transfer coefficient Ud=1.3 W/m2K. Carpentry replacement area: 33.1m2 – 9 pieces In addition, the required demolition works will be carried out. III. Modernization of the central heating system (heating system) The installation of a new RES-type heat source has been designed, i.e.: a pellet boiler with a power of not less than 73kW with the replacement of a c.o. installation of valves under vertical and thermostatic on all radiators together with a buffer tank and weather automation, as well as the necessary accompanying and restoration works after the installation has been modernized. IV. Repair of bands around buildings and approaches to the building - band with a width of 50 cm made of granite grit 15cm on non-woven fabric with additional protection from the concrete edge 8/30/100cm. Locally, the band is a project
