Economical analysis of determination thermal insulation thickness for different external walls

Abstract

In the countries which supply big amount of their energy needs by import like Turkey using the energy economically is important. Thermal insulation technologies in buildings are the main method for using energy economically. But choosing the thickness of the insulation material redundant causes high insulation costs. For this reason, an optimum point which provides the highest price in insulation applications is the subject. In this study, different building materials (horizontal perforated brick and gas concrete), and isolated forms of insulation (exterior insulation and insulation sandwich) was a model of a building exterior wall. The study determined that the wall and the heat loss through the life-cost analysis, according to the present calculations (LCCA), the optimum thickness of insulation, energy savings and payback periods were determined.
