Yüksek Performanslı Bina Tasarımında Isı Yalıtım Malzemesi Seçimi İçin Bir Yaklaşım

Bu çalışma, yüksek performanslı bina tasarımında ısı yalıtım malzemesinin seçimi için çok kriterli bir karar verme yaklaşımı sunmaktadır. Önerilen yaklaşım, Türkiye’de yaygın uygulanan bir sosyal konut arketipine uygulanmıştır. Bu amaçla, öncelikle ‘yüksek performans’ için hedeflenen kriterler belirlenmiş, bu kriterler üzerinden bağımsız değişkenler tespit edilmiştir. Bağımsız değişkenler üzerinden parametrik analiz metodu ile alternatif senaryolar üretilmiş, hedeflenen performans kriterleri olan yaşam döngüsü, enerji, maliyet ve çevresel etki değerleri hesaplatılmıştır. Performans hesaplamalarında Energy Plus dinamik simülasyon aracı kullanılmıştır. Sonuçlar, etüt edilen arketip için en iyi alternatifleri belirlemeye yönelik birçok kriterli karar verme yaklaşımı olarak önerilen Ağırlıklı Toplam Metodu (WSM) ile değerlendirilmiştir. Sonuçlar göstermektedir ki; farklı ısıl, çevresel ve ekonomik özelliklere sahip ısı yalıtım malzemeleri içerisinden doğru seçim yapılması, binalarda yüksek performans hedeflerinin sağlanmasında oldukça etkilidir.

An Approach to the Selection of Thermal Insulation Material in High Performance Building Design

This study proposes an approach based on a multiple criteria decision-making method for the selection of thermal insulation material in the design of high performance social housing. The proposed approach has been studied on a common social housing archetype in Turkey. Independent variables such as thermal insulation material and application thicknesses were determined and parametric analysis method was used to investigate the performance of the archetype through 25 alternative scenarios. Secondly, decision making criteria for energy, cost, and environmental impact performances were calculated for each alternative. Calculations were conducted through the Energy Plus dynamic building energy simulation tool. Finally, results were evaluated through the proposed Weighted Sum Method (WSM) as a multiple criteria decision making approach to determine the best alternatives for the studied archetype. Consequently, results show that a proper decision making on selection of thermal insulation material with different environmental and economic attributes, ensures the higher performance of buildings.
