EVALUATION OF THE THERMAL INSULATION PERFORMANCE OF THE GROUND FLOOR OF AN A++ CLASS PUBLIC BUILDING USING THE SAW METHOD

Summary/Abstract: This paper investigates the Simple Added Weighting (SAW) method for evaluating the thermal insulation performance of the ground floor of an A++ class public building. Four alternative insulation materials (ŠILPUTA EPS100; FF-EPS100S; FINNFOAM F-200; PAROC GRS 20) were evaluated on the basis of six criteria: the compressive strength up to 10% deformation, the design value of thermal conductivity coefficient, the thickness of the thermal insulation layer, the cost (Q4 2023), the global warming potential (GWP) and the long-term water absorption of the insulation material. The results of the empirical research indicate that FINNFOAM F-200 is the most effective thermal insulation material for the ground floor insulation of a nearly zero-energy public building. The highest relative performance score (0.87) was achieved by this material. Rock wool PAROC GRS 20 is the least effective (0.51 points) alternative (from the four tested materials).
