Optimizing Window Thermophysical Properties for Reducing Energy Demands, Energy Costs, and Greenhouse Gas Emissions in Residential Buildings of Türkiye

Öz

Selecting the right building envelope based on climate and building type is considered an important passive design strategy for energy efficiency of buildings. Revision of thermo-physical properties of building envelope in the building codes given their significant effects on thermal performance can reduce the annual energy demands, energy costs, and greenhouse gas emissions of all the buildings, ensuring a significant momentum towards achieving the 2030 Sustainable Development Goals (SDGs). This study reevaluated the reference thermo-physical property of windows (U-value: 2.4 W/m2.K) in the TS825 Thermal Insulation Requirements in Buildings standard based on three separate thermo-physical categories (U-value, SHGC, and T-vis) to recommend an optimum window option to improve the sustainability of residential buildings in Turkey align with the 11th, 12th, and 13th goals of 2030 SDGs. Accordingly, the energy performance of reference window type referred in TS825 standard was tested for a sample residential building in Istanbul, located in the standard 2nd degree day region using the DesignBuilder building energy simulation tool. Afterwards, in alignment with the 11th goal of the 2030 SDGs, various new window types (frame + glass) were proposed, and their impact on the annual energy demand of a sample building was analyzed. In the second phase, the effects of these window systems on energy costs were examined in accordance with the 12th goal. Finally, in the third phase, their impact on greenhouse gas emissions was assessed in relation to the 13th goal. The research identified that the window types optimizing the annual energy demand, energy cost, and greenhouse gas emissions of the building are W7 (U-value: 1.783 W/m².K, SHGC: 0.402, T-vis: 0.608), W17 (U-value: 1.156 W/m².K, SHGC: 0.478, T-vis: 0.591) and W19 (U-value: 1.071 W/m².K, SHGC: 0.359, T-vis: 0.474). These windows are filled with Krypton gas, and the window frame materials are PVC. The glazing material of W7 is Low-e, whereas W17 and W19 are polymer. The W7, W17 and W19 window types achieved improvements of 11.58%, 18.38% and 21.29% in the building's total annual energy demand, respectively.
