TY - JOUR TI - Ecological and economic analysis of a building heating system thermomodernization efficiency AU - Pawłowska, Agata TI - Ecological and economic analysis of a building heating system thermomodernization efficiency AB - The paper presents a project of a building heating system thermomodernization. Currently, the building is not insulated which results in great heat losses and, consequently, high maintenance costs. The essential calculations performed by the Audytor OZC 4.8 Pro programme enable to estimate the range of a thermomodernization and payback period of thermomodernization. The report contains ecological analysis showing the annual reduction of the pollutants released into the atmosphere.
