Abstract :The performance of the building envelope is evaluated with the different options applied to an office building example, and a new envelope proposal is presented to replace mechanical heating systems in buildings within the scope of a san-thesis project in this study. The heating system and wall-structural elements integration were designed in the new envelope proposal. An alternative wall element has been created such as modularity, easy applicability and economy. The other wall sections considered are brick, aerated concrete and the existing glass curtain wall. Heat, sound and cost parameters are considered as building envelope performance criteria. Building envelope alternatives were evaluated with the TOPSIS (Multi Criteria Decision Making) method. As a result of the comparisons made in 3 pilot provinces, the most appropriate cross section decision was obtained. This study, which was developed both as a new approach as an alternative to the building envelope and as a new system proposal for architectural designers in the field of application. Also, it constitutes a source for holistic approaches in the combination of new building elements and / or systems to be developed in the future.
