Özet:

A considerable amount of energy is consumed in buildings because of the economic developments and the increased population. By taking in consideration that 40% of total energy use is consumed in the building, the proper design of building’s envelope is crucial for reducing the negative effects of high energy consumption in the economy and environment of a country. This study aims to investigate the proper design alternatives on the reduction of energy consumption and life-cycle cost (LCC) of residential buildings for heating and cooling purposes. The study is carried out in two cities, Ankara and Antalya, which represents the cold and hot climate region. For this study, the same flat of 1+1 floor plan designed for a family of two in a reference residential building project is simulated with different location, in Ankara and Antalya. For these flats, the annual zone heating and total cooling energy consumptions and life cycle costs are calculated using DesignBuilder simulation program according to different window-wall ratios, glazing types and insulation thickness. Window assembly alternatives are composed of double glazing units with clear glass, low-e glass, blue tinted glass and reflective glass and PVC frame. While the investigated insulation thickness options are EPS 100 mm and EPS 50 mm. At the end of the study, energy and cost efficient design alternatives for cold and hot climate regions are proposed.
