Providing an Optimal Execution Model for Windows Based on Glazing to Reduce Fossil Fuel Consumption (Case Study: Asman Residential Complex of Tabriz)

Abstract

According to statistics provided by the Iranian Statistics Center,40% of energy consumption is related to the housing sector. Windows as a component of exterior wall, Responsible for 20-30% of all energy infiltration. Therefore, the purpose of this study, is to optimize residential windows in cold and dry climate of Tabriz in order to reduce energy consumption. The research method is based on simulation with two methods "parametric optimization" and "genetic algorithm". The research tool is Design Builder software. So, the amount of annual gas consumption in the case study was received from the National Iranian Gas Company and then the basic research model is modeled in software and after converting the unit from kWh to m 3 and validating the obtained results from simulation, in the next step, the type of glazing and frame are changed and then the sensitivity is analyzed by the two mentioned methods. The results showed that by replacing windows with triple glazedglazing with low emission coating filled with argon, krypton and xenon gas and UPVC frame with clear double glazed-glazing filled with argon gas and iron frame, annual gas consumption for heating decreased by 52.43%, 55.34% and 56.60% and the heat loss from the windows is reduced by 7.97%, 9.54% and 10.49%, respectively.

Energy Efficient Design Optimization of a Building Envelope in a Temperate and Humid Climate

“…Increasing the size of the windows to 35%WWR and 45%WWR have also resulted in the same conditions with a higher increase in heating and cooling loads differences. Results reported by Abdoly Naser et al [31] also showed glazing with low emission coating will decrease, heat loss decreased and annual gas consumption. While reflective coatings on the surface of the glass reduce the receipt of solar energy by 90.86% and therefore this type of glazing is not suitable in cold seasons.…”

Optimization of Thermal Performance of Windows in Intermediate Housing in Cold and Dry Climate of Tabriz

“…There are three very important reasons for the high heat losses from windows: window to wall ratio (WWR); window orientation; and type of window glazing [5]. Due to its low thickness, glazing has the highest heat transfer coefficient among the elements of the building's exterior shell and also the window to wall ratio is one of the most important factors in energy consumption in designing buildings in cold climates [6]. Therefore, the purpose of this study is to present the design criteria and implementation of windows in residential buildings in the cold and dry climate of Tabriz in order to reduce energy consumption.…”

An Optimal Model for Designing and Executing Windows in Tabriz Residential Buildings to Reduce Energy Consumption

“…Abdoli Naser et al [12] studied the optimal execution model for windows. For optimization, triple-glazed glazing with low emission coating e = 0.1 is recommended.…”
