- Abstract
The paper presents a multi-objective optimization solution on the basis of ratio analysis and the assessment of the effectiveness of the thermal insulation layer of the flat roof of a class A++ industrial building. The MOORA method was selected for the evaluation of the effectiveness of the middle layer of the thermal insulation material. Five different thermal insulation materials (Paroc ROS 30; EPS100; EPS80N; XPS300; FF-PIR ALK) were assessed according to 4 objectives: the thickness of the thermal insulation layer; the density; the thermal conductivity coefficient; and the price (the third quarter of 2022) of insulation material. Findings of the performed analytical study suggest that the graphite polystyrene foam EPS80N is the most effective thermal insulation material for the flat roof of the nearly zeroenergy industrial building. This material scored the highest number of the relative efficiency points (-0.318). The least effective alternative (from the five tested materials) is the rock wool - Paroc ROS 30 (-0.618 points). The difference between the best and worst alternatives is 51.46 percent.
