A reduction to 25% to 50% of energy consumption is possible with only proper insulation of these buildings. Fossil fuels such as coal and petroleum produce CO 2. Tests have shown that CO 2 levels have reached 360 ppm in Turkey. In this context, buildings that are efficiently designed and configured will provide energy savings. Energy efficiency in buildings in Turkey, has gained prominence recently with the adoption of the Directive on Energy Performance of Buildings in 2008. The object of this study is to convert a building, located in the 3rd climatic region in Turkey, to an energy efficient one. Analysis of the building has revealed that it does not accommodate the TS 825 s tandards. New thermal insulation design has cut energy consumption estimates to 37,09 kWh/m 3 , which is within the limits of regulation codes.

It also has macro-economic and especially, monetary instability. The net effect of these factors is that Turkey’s energy demand has grown rapidly almost every year and is expected to continue growing. Since 1990, energy consumption has increased at an annual average rate of 4.3%. The energy consumption is distributed among four main sectors which are industrial, building (residential), transportation and agriculture. Approximately 33% of total energy consumption in Turkey is used by residential sector. This situation makes it more important to insulate buildings in our country where fuel prices are too high. Turkey is divided into four climatic zones depending on average temperature degree days of heating. In this study, the four different cities of Turkey, Izmir, Istanbul, Ankara and Erzurum are selected to determine the optimum insulation thickness of the external wall of buildings. Optimum insulation thickness for six different energy sources (Soma coal, natural gas, coal, LPG, fuel-oil, diesel fuel) and two different insulants (extruded polystyrene, rock wool) is calculated and compared to each other. In addition, by using life cycle cost analysis method. Pay back period is calculated for each zone.

Generally, feed-water economizers and air preheaters are used for this aim in steam boilers to recover heat from the flue gases. The measurements of volumetric percentages O2 (5.7%) and CO (0%) in flue gas,
