Evaluating cost-optimality of high-rise buildings by considering outdoor air rates in TS825 standard

Abstract

The construction of high-rise residential buildings has been increasing dramatically, but a crucial part of energy consumption of these buildings still depends on fossil fuels. Furthermore, the global costs of these buildings are extremely high compared with the other residential building types due to the mechanical ventilation demands. Thus, it is necessary to improve through both energy consumption and global cost of these buildings. In the present study, the cost-optimum energy-efficient level of the high- rise residential building in Turkey was evaluated by using the cost-optimal methodology introduced in Directive 2010/31/EC by European Union. When the fresh air rates of air handling units of the case study building were revised in accordance with TS825 standard, which is the national Turkish building code of Turkey, it was concluded that the annual primary energy consumption and global cost of this building was improved by 44.2% and 22.73 e/m, respectively. © 2024, IGI Global.
