Özet:

This study investigated effective ways of minimizing the amount of energy used for heating and cooling caused by windows in the building envelope. The use of glass material in windows is discussed in terms of reducing heating and cooling energy consumption. The hourly total heating and cooling energy calculations were carried out for the 1st, 11th, and 21st days of each month using the previous 10-year period's meteorological data for Elazığ. Energy loads of windows were estimated using a computer program written in MATLAB. Energy requirements of different building facade examples caused by window glass were evaluated and the optimum facades determined among different alternatives. In conclusion, OR1/1 (square formed) buildings have the minimum heating and cooling requirements. Among 5 different glass alternatives, xenon filled double glass units require 33%-82% less heating and cooling energy than the others.
