In the context of high-level goals, particular importance is given not only to the declaration of ambitious modernization of multifamily buildings itself, but also to the method of pursuing the goals set out in the European Green Deal, which can only be achieved by the cooperation of building owners and managers, who should complete such a process by 2050. They should have knowledge of what, how and how much can be improved to improve the energy standard of their buildings, with the greatest economic effect for its inhabitants. Current functioning of the real estate managers’ market is not conducive to the obligatory improvement of professional qualifications, therefore all initiatives changing this situation should be supported by both voluntary associations and the managers themselves. Social research has shown that the areas for expansion most often indicated by managers are basic knowledge of the energy efficiency of buildings (21% of responses) and knowledge about obtaining and using funds for investments related to the improvement of the energy efficiency of buildings (19% of responses). An important area seems to be the need to exchange experiences between managers - indicated by 12%, but this is an area with potential. Almost all managers are aware of the economic benefits that result from improving the energy efficiency of multi-family buildings. To improve the situation of managing and administering the Home Owners Associations and reduce their negative impact on climate change, the new training curricula will be developed in stationary and e-learning mode.
