BİNA DIŞ DUVARLARININ OPTİMUM YALITIM KALINLIKLARI İÇİN DİNAMİK YAKLAŞIM VE MALİYET ANALİZİ.

The optimum thickness of insulation applying on external walls of building was investigated under dynamic thermal conditions. Therefore, the yearly heating transmission load was calculated by using an implicit finite differences method under steady periodic conditions. Calculations were done by considering external environment conditions of Elazığ city. Extruded polystyrene was used as the insulation material, and coal, fueloil and natural gas were used as fuel. Then, cost analysis was done for a south facing wall insulated on outside. The optimum insulation thicknesses, the energy savings and payback periods were calculated for every fuel type. As result, optimum insulation thickness for Elazığ was obtained to be 0.040 m when natural gas was used. [ABSTRACT FROM AUTHOR]
