Abstract
The importance of building energy performance has been substantially increasing in the last decades due to the global warming. Therefore, buildings within the existing stock and the new buildings are encouraged to achieve the energy performance restrictions and efficiency levels. In this context, a social housing archetype (Harct), which is constructed in each climate region of Turkey with a common design approach for temperate climate region, is evaluated as a base case to improve the energy performance for the cold climate region by the optimization of the life cycle cost (LCC). It is, namely, aimed to not only improve the energy performance of the archetype but also to ensure optimal cost efficiency as significant criterion. It is focused to optimize the façades of the Harct in terms of window width, and optic and thermo-physical properties of the façade with determining the efficient insulation thickness level for exterior walls and efficient glazing types for windows. Firstly, façade design is analysed to find out the minimum and maximum windows’ widths to achieve the optimal window sizes. Secondly, optic and thermo-physical properties and cost data of the opaque and transparent façade elements have been designated among the market products in accordance with the current regulations. Energy model of the building has been run by Energy Plus simulation tool, in order to integrate it with GenOpt for optimization. Optimization was performed to carry out efficient frontier cases. The results were evaluated from life cycle cost (LCC) and energy efficiency point of view to highlight the cost optimal point

Building stock is one of the major actors on global warming, by consuming approximately %40 of the total global energy consumption It is precisely essential for decision makers to take the energy efficiency of new and existing buildings into consideration, in order to deal with the global warming issue. EPBD Recast [2] defines the “cost optimal levels of minimum energy performance requirements” so that those requirements should be set with a view to achieve the cost-optimal balance between the investments involved and the energy costs saved throughout the lifecycle of the building In this context, this study aims to achieve cost optimal energy efficient alternatives for a selected multistory social housing archetype, which is constructed by the Housing Development Administration of Turkey (TOKİ) in each climatic region of Turkey with similar approaches. This study focuses on the cold climate and the cardinal directions are taken into consideration so that the assigned independent variables are applied on the north, south, and east & west facades, separately
