Application of Hierarchical Analysis Method To Design The Structural Partitions With Different Material And Structural Solutions For Window Glazing

The aim of this study was to use AHP method to analyze seven types of windows in terms of cost-effectiveness of their designing in building partitions. The analysis referred to price as well as thermal and acoustic insulation for various construction and material solutions of window glazing. Using the analysis it was verified what windows are profitable to be used for various structural solutions in the existing buildings and how the thermal and acoustic coefficient is shaped at given structural solutions. Currently employed requirements for technical parameters of window and door frames adopted in regulations and standards are firmly tightened, including one saying that, since 1.01.2014 heat transfer coefficient for the window cannot be higher than 1.3 W/(m²K), (Polish requirement) which is why all producers’ offers analyzed in this study have high standard technical features. of course, among them there are better and worse offers, but each of them is sufficient in the light of the provisions and standards. That is why the work uses the price per set of two windows as a decisive and most essential criterion. The employed research method involves selecting windows available on the market with different thermal, acoustic parameters and price, and then using the AHP method the best solution was chosen for a wide variety of structural walls significantly different in heat transfer coefficient. The result of the work is to determine the windows parameters applied for a variety of wall constructions.
