This article presents an analysis of how the construction and insulation materials used for the walls of a sports hall built according to passive design affect the overall construction costs. The authors also attempt to answer whether the objective of achieving the lowest possible energy consumption in a building is actually economically sound. Cost analyses will be carried out to this end, the optimum insulation thickness will be determined, and the time necessary to balance the investment expenditure will be calculated for an energy-efficient construction project.
