Reduction of air pollution as a basis for a healthy urban environment

The WHO report shows that air in the majority of cities in the world is polluted to a large extent. Air pollution is one of the basic environmental causes of premature deaths in the world. The main source of air pollution in cities is the low emission associated with fuel combustion to generate heat for buildings heating, communication and industry. The existing buildings in Poland are characterized by high energy and, consequently, ecological potential. The aim is to estimate predicted energetic and ecological effects of activities that adapt existing residential buildings to the requirements for the thermal protection of buildings in Poland and presenting the possibility of using renewable energy sources. The energy demand for heating buildings at 60-70 kWhl(m(2)rok) has been adopted. The calculations show that as a result of this adjustment, the energy demand for heating in residential buildings may decrease by an average of around 67% compared to 2011. Such actions will reduce the overall emissions of air pollution from households by reducing the energy requirement for heating apartments from about 30% to about 67%, depending on the type of pollutant.
