AN ENERGY PERFORMANCE BASED DECISION SUPPORT SYSTEM FOR NORTH FACING SETTLEMENTS

Hilal Parlak Arslan, Gül Koçlar Oral

Abstract: The energy-efficient building design process is an iterative process in which many parameters that can affect the energy loads of the buildings are observed. It is known that the decisions taken during the early design stage have an impact on the energy consumed by the buildings during the production and usage stages. While considering the effect of building design parameters on building energy performance, it is necessary to analyze the effect of the parameters to make decisions among many parameters. Decision support systems are needed when decisions should be made by considering multiple parameters to improve the energy performance of the buildings, especially when building design parameters have a limiting effect on energy efficiency. In energy-efficient design, wide facades of buildings are expected to be oriented to the south, especially in cold and temperate climatic regions where the heating period is longer, while in regions where the view is to the north, wide facades of the buildings may be oriented to the north. It is seen that the orientation to the view has a limiting effect on the orientation to optimize the solar radiation gain for energy efficiency. Situations with such limiting effects may appear as design problems where the effect of more than one parameter should be considered. In this study, it is aimed to produce optimum solutions in non-optimally oriented buildings. For this purpose, it has been studied to analyze the design parameters of the residential buildings oriented to the north and to determine the facade proposals to reduce the energy loads. To accomplish this, first generating the building energy model, then the sensitivity analysis of the facade design parameters, and finally optimization of the annual heating energy loads, cooling energy loads, and CO2 emissions has been taken into account. Sensitivity analysis and optimization methods are decision support systems for solving problems that involve evaluation according to multiple criteria. With the optimization results, it is expected to produce an output in which all the facade parameters are considered together in the non-optimal orientated residential buildings.
