Zagadnienie poprawy efektywności energetycznej jest jednym z najbardziej uzasadnionych ekonomicznie sposobów zmniejszenia emisji gazów cieplarnianych do atmosfery. W artykule omówiono korzyści ekologiczne wynikające z przeprowadzenia inwestycji polegającej na termoizolacji przegród zewnętrznych budowlanych. Wyznaczono optymalne wartości współczynnika przenikania ciepła pionowej przegrody zewnętrznej, ekologiczną wartość inwestycji oraz ekologiczną efektywność kosztową. Zastosowano wielowariantowość układów budowy przegrody zewnętrznej w odniesieniu do materiałów konstrukcyjnych oraz termoizolacyjnych. Dodatkowo wzięto pod uwagę lokalizację budynku w różnych pięciu strefach klimatycznych Polski oraz źródło ciepła stosowane w budynku.

The issue of improving energy efficiency is one of the most economically viable ways of reducing greenhouse gases’ emission into the atmosphere. The article discusses ecological benefits arising from the performance of the investment based on the thermal insulation of building external walls. The authors determined optimal values of the heat transfer coefficient of the vertical external wall, ecological value of the investment and ecological cost efficiency. Multi-variant systems of the external wall structure were used with respect to construction and thermal insulation materials. Moreover, the location of the building in five different climatic zones in Poland was taken into consideration as well as the heat source used in the building.

Plaster plays an important role in the building industry. Besides an aesthetic function it provides the protection of external walls from weather conditions. In the paper thermo insulating Thermopor plaster was described. Its chemical and physical properties and manner of using were defined. The impact on the environment with the use of LCA technique was examined. Thermopor plaster can fulfil a thermo insulating function. The economic and ecological analysis of applying this plaster in the thermo insulation of the external walls of the building was conducted. The use of Thermopor plaster on external walls brings ecological benefits. The reimbursement of ecological cost related to the use of this plaster appears already after 2 to 5 years, depending on the source of heat used, which results from the decrease of thermal energy consumption for heating the building. For economic reasons, the partial reimbursement of cost is obtained as a result of the reduction of heating cost. Although Thermopor plaster has thermo insulating properties similar to typical insulating materials, such as polystyrene or mineral wool, the economic cost of using the plaster for thermo insulation becomes several times higher.

The article proposes the manner of determining ecological benefits, which result from thermo insulation of the external walls of the building. In order to assign environment load the technique of life cycle assessment LCA was used, including the division into three damage categories: human health, ecosystem quality and raw materials. The production of thermo insulating materials causes the increase of the environment load, but in the thermal phase of the building usage the negative impact on the environment is reduced due to the reduction of energy demand necessary to heat. A few dozen of thermo insulation variants were examined, depending on the kind of wall, heat source and thermo insulating material. For all cases the analyzed investment turned out to be cost effective in terms of ecological aspects. In each damage category the reduction of the environment load was obtained. The ecological payback period was obtained within 0–5 years.
