Energy Simulation Optimization for Building Insulation Materials

Abstract

Recently increased energy consumption and carbon emissions caused by energy consumption have mobilized governments. Energy-efficient building designs have become one of the most fundamental strategies preferred by governments. The heating and cooling demands have an important share in energy consumption in buildings. Therefore, thermal insulation systems have become the basic building elements to design energy-efficient buildings. Determining suitable thermal insulation strategies for energy-efficient structures built in different climates is an important decision problem for designers. This study aims to select insulation material and insulation thickness for energy-efficient building design. The stone wool, extruded polystyrene (XPS) insulation materials, and their alternative thicknesses are considered for Turkey’s two different climate zones. The Energy Plus and Design Builder energy simulation programs are used to analyze all alternatives. A decision support system is generated by considering both the material cost and the heating and cooling energies to be consumed during the building life cycle. The most suitable insulation material for the first zone is stone wool, and its thickness is 10 cm. The most suitable insulation material for the second zone is stone wool, and its thickness is 10 cm. The total saving is 11% for the building in the first zone. The total saving is 9% for the building in the second zone. The generated designs have been quite stimulating for decision-makers. © 2024 Elsevier B.V., All rights reserved.
