Air Pollution and Energy Unefficiency of Settlement Structures in the Context of Spatial Chaos in Poland (Chosen Examples from Lower Silesia). The deregulated spatial planning system in Poland has led to an emergence of incalculable economic, environmental and public costs that burden the society. Investment liberty is accompanied by a lack of coordination in the development of housing areas with public transport, electricity, gas and heating infrastructure. At the same time, revitalization is interpreted as a form of physical modernization of buildings, but not as social renewal. The result of spatial disorder is a reduction of energy efficiency of entire settlement structures, not just individual buildings. Old-fashioned methods of supplying buildings with heat, responsible for local emission, are sustained. Comprehensively, this condition contributes to the deterioration of air quality indicators in Poland.
