Abstract

In daily life, people spend most of their time indoors. This situation increases the need to keep indoor

environments warm in winter and cool in summer. This directly increases energy consumption. Since energy

dependence is dependent on fossil fuels and causes severe environmental pollution, energy consumption can

be significantly reduced with insulation applications to be made in buildings. Windows are responsible for

approximately 40% of the heat transfer in buildings. For this, reducing heat losses through windows can

significantly reduce energy consumption. This study aims to restrict air movement with barriers in doubleglazed

windows. By preventing the air movement between the double glazing, the natural convection effects

will weaken and decrease the heat transmission coefficient. The 2D CFD model is verified by using ANSYS

engineering commercial software and the heat transfer coefficient (Uw) of the insulated glass with air within

20 mm is determined as approximately 1.6 W/m2K. Then, the change in the heat transfer coefficient of the

insulating glass is evaluated with differently positioned barriers. It is seen that the barrier placed diagonally

reduces the heat transfer coefficient. It is seen that the heat transfer coefficient of the insulating glass with the

barriers placed in two different ways is 1.4 W/m2K and 1.52 W/m2K, respectively. Similarly, it is understood

that the thickness of the insulating glass also affects the heat transfer coefficient. This study shows that the

heat loss from the windows can be reduced by up to 12.5% by using a barrier.
