Możliwość poprawy jakości powietrza w polskich szkołach w wyniku modernizacji opartej na zasadach zrównoważonego rozwoju

The paper describes part of the results of the Polish/Norwegian scientific cooperation within the project SUREBUILD, funded by the Norwegian Ministry of Foreign Affairs. The whole project is devoted to sustainable redevelopment of buildings in Poland, but special attention was paid to Polish schools constructed between 1958-1966 (the "Millenium" schools). Potential technologies for sustainable modernization of Polish schools were analyzed taking into consideration energetic, environmental, economic and other related criterions. Substantial part of the work was devoted to fin d the economically feasible technologies that might improve current unsatisfactory level of indoor air quality in Polish schools. The paper presents general recommendations for the moderniza- tion of ventilation system s in Polish schools as well as describes the technologies selected for school in Zgierz, the case study object of the project.
