On the basis of audit surveys concerning modernization of heating systems in middle-sized towns (of 16 to 65 thousand inhabitants), a technical-economic analysis as well as an ecological analysis of feasible investment projects were performed. The audit surveys concentrated mainly on 152 local low-temperature boiler houses with low emission sources in selected towns of the north-eastern Poland. The audit surveys mentioned above involved also measurements of the amounts of SO2 and particulate matter polluting the air. The fundamental purpose of the suggested modernization of the researched heating systems was to improve the very low operating efficiency of the boiler houses (mainly with low emission sources) under concern, as well as - or perhaps above all - to reduce levels of SO2 and particulate matter polluting the air. One of the criteria applied in the economic assessment of the suggested projects (investments) was the Net Present Value (NPV), whereas in the case of the ecological assessment - reducing air pollution.

Na podstawie opracowań dotyczących modernizacji gospodarki cieplnej w miastach średniej wielkości (od 16 do 65 tysięcy mieszkańców) przeprowadzono analizę techniczno-ekonomiczną oraz ekologiczną możliwych do zrealizowania przedsięwzięć modernizacyjnych. Opracowania audytorskie dotyczyły głównie lokalnych kotłowni niskotemperaturowych (152 kotłownie) z niskimi emitorami w wybranych miastach w północno-wschodnim rejonie Polski. W ramach ww. opracowań wykonano również pomiary zanieczyszczeń powietrza SO2 oraz pyłami. Zasadniczym celem zaproponowanych modernizacji systemów ciepłowniczych było poprawienie bardzo niskich sprawności eksploatacyjnych kotłowni, głównie z niskimi emitorami, a także (a może przede wszystkim) obniżenie zanieczyszczeń powietrza SO2 oraz pyłami. Jednym z kryteriów oceny ekonomicznej zaproponowanych przedsięwzięć (inwestycji) była Aktualna Wartość Netto (NPV), natomiast oceny ekologicznej - redukcja zanieczyszczeń powietrza.
