Optimum building envelope design for visual, thermal and acoustical comfort conditions in the offices.

The aim of this paper is to explain the results of a research project run in Yildiz Technical University which focuses on the optimum building envelope design for visual, thermal and acoustical comfort conditions in the offices placed in Istanbul city center. In this project, the building envelope alternatives are examined in terms of light, heat and sound considering the materials used mostly in Turkey. The applied method is assessment of the various building envelopes from the point of the view of the natural light, heat and sound, comparison of the outcomes and determination of the optimum building alternatives.
