Yapı Malzemelerine Sürdürülebilir Mimarlık Bağlamında Bütüncül Bir Bakış: Duvar Malzemelerinin Çevresel Etkilerinin ve Enerji Performansının Belirlenmesi

Öz

Yapı sektörü malzeme ve enerji kaynaklarının büyük bir kısmını tüketirken, sektörün çevreye etkileri de tüketimle aynı oranda gerçekleşmektedir. Bu bağlamda, yapı malzemelerinin sürdürülebilirlik bağlamında ele alınması durumunda, hem enerji performansı hem de çevreye etkilerini ele alan bütüncül bir bakış açısıyla irdelenmesi, yapının tasarım evresinde gerçekleşen malzeme seçiminin daha doğru ve rasyonel olması için önemlidir. Çalışma kapsamında duvar konstrüksiyonlarında kullanılan tuğla, gazbeton ve bims bloğun çevresel etkileri ve yapının kullanım evresindeki enerji performasına ve kabuğun ısıl kütle özelliğine etkileri Safranbolu’da inşa edilmiş bir toplu konut projesi üzerinden irdelenmiş ve duvar malzemeleri sürdürülebilir mimarlık bağlamında bütüncül bir bakış açısıyla ele alınmıştır. Çalışma sonucunda, tuğlanın gazbeton ve bims bloğa göre üretim sürecindeki yüksek ısı enerjisi gereksinimi nedeniyle çevresel etkileri daha fazla olmasına karşın yapının enerji performansını ve kabuğun ısı depolama kapasitesini artırdığı tespit edilmiştir.

A Holistic View on Building Materials in the Context of Sustainable Architecture: Determining the Environmental Impact and Energy Performance of Wall Materials

Abstract

While the construction sector consumes a large part of material and energy resources, its effects on the environment occur at the same rate as consumption. In this context, if building materials are handled in the context of sustainability, it is important to examine both energy performance and environmental effects from a holistic perspective, so that the material selection realized during the design phase of the building is more accurate and rational. Within the scope of the study, the environmental effects of brick, aerated concrete and pumice block used in wall constructions and their effects on the energy performance of the building and the thermal mass of the shell were examined through a mass housing project built in Safranbolu and the wall materials were discussed from a holistic perspective in the context of sustainable architecture. As a result of the study, it has been determined that although the brick has more environmental effects due to the high heat energy requirement in the production process compared to aerated concrete and pumice blocks, it increases the energy performance of the building and the heat storage capacity of the shell.
