Investigation of the effects of the windows with different properties on building energy performance

In this thesis; building energy simulation was carried out by concerning different types of glazing options for a residental building. The building consists of six stories including basement and it has four apartments on each floor. 22 glazing options were considered with different thermo-physical properties under the climate conditions of Kayseri and Osmaniye provinces. Heat transfer coefficient (U), solar heat gain coefficient (SHGC) and visible transmittance (VT) vere considered as input parameteres. EnergyPlus building energy simulation program was used in energy calculations. At the first phase of the study, 2 glazing types were determined among 22 types that caused the highest thermal and overall energy consumption for both provinces. Then, window to wall ratio (WWR) was varied between 0.2 and 0.8 for previously determined glazing types and their effects on building total energy consumption were investigated. According to the results of the study, ideal glass types should be determined for each climate type, depending on the U, GIKK and GIGK values. In addition, it has been determined that there is no decrease in the annual total energy consumption of the building for each province as the WWR values increase.
