The project is an infrastructure project aimed at improving the quality of atmospheric air in and around Bydgoszcz and reducing heat losses. The maintenance of air quality standards is linked to the reduction of emissions of gaseous and particulate pollutants arising from the production of heat. Action is needed to increase thermal efficiency and reduce heat losses. The scope of the project concerns the implementation of thermomodernisation of the Centre’s Main Team located in the area of plot No 1/25 within 248 at 2 Dr. Izabela Romanowska Street in Bydgoszcz, consisting of: Reconstruction of the heating system in the scope, reconstruction of the steam-water node supplying the facilities of this Team, hydraulic balancing of internal central heating systems and heating heating systems of the Main Team’s premises and into technological heat heaters of ventilation and air conditioning systems. The conversion of the heat node of the Main Team concerns the replacement of the heat node located in the technical floor of the diagnostic and therapeutic building, into a modern technical standard. Insulation of building stropods, by replacing the roof covering together with sheet treatment of individual roofs (new galvanised sheet treatment), ventilation fireplaces (air vents) or optional dismantling of existing stropoda ventilation holes, control and possibly cleaning of impurities from the ceiling space, control of the ventilation status and installation, complete dismantling of the existing spike vents, control of the existing roofing, damping and possibly cleaning of new ceilings, ventilation and installation, complete dismantling of existing spires, damping and lightning systems,
