The facades of the buildings, which are very effective in the energy efficiency of the buildings and constitute a large proportion of the building envelope, are built independently of all the contexts of its location and the spatial needs based on comfort conditions. Glass curtain facades, which are especially located in the facade systems of multi-storey office buildings, are constructed with similar qualities on each facade of the buildings and cause problems in the efficient consumption of energy as they cannot respond adequately to the comfort conditions of the spaces. Increasing cooling loads of buildings due to excessive heat gain from large transparent surfaces, is one of these problems.
