Optimizing the thermal energy consumption in heating systems of residential buildings: A case study

The reduction of fossil fuels and pollution caused by the consumption of this type of fuel, on the one hand, and the high consumption of this energy in residential buildings, on the other hand, have led this research to propose solutions to optimize the consumption of thermal energy (heating) considering the economic considerations in residential homes. Relevant practical data have been applied to realize these goals. The results are the product of the output data of the studied building. To this end, the studied building was selected in Ardabil, Iran’s cold position. The amount of loss in various sections, such as windows and other physical elements for this building, has been evaluated, places that need energy audits have been identified, and the solution implementation results have been prepared. Economic parameters were also involved in choosing the best and most optimal solution and further reducing energy consumption. One of the important results was installing and sealing doors and windows with fiberglass (thickness 2.5 mm, density 43). The payback period for this solution was equal to 0.021 years, which has reduced the annual energy consumption of the building by as much as 12716938 kJ.
