The life cycle assessment related to insulation thickness of external walls of the airport

In this study, energy savings to be gained by the insulation of the external walls of airport buildings are examined according to Turkish Building Insulation Standard (TS 825) which is renewed in December 2013. In addition, life cycle total (LCT) cost and life cycle savings (LCS) are calculated. Unlike the residences, the airport buildings indoor temperatures should be 20°C during the heating period according. The optimum insulation thickness was determined for the external walls of the airport buildings. The degree-of-day method is used in calculations. Optimum insulation thickness is the lowest polyurethane insulation material in the highest glass wool insulation material. The optimum insulation thickness is calculated as 0.044-0.090 m for the polyurethane insulation material and 0.122-0.233 m for the glass wool insulation material. Also, extruded polystyrene (XPS) insulation material was found between 0.062-0.125 m.
