Son yıllarda, yapı malzemelerinin ve bileşenlerinin çevresel etkilerinin değerlendirilmesine artan bir ilgi vardır. Bu çevresel etkiler göz önünde bulundurularak, kullanıcı ihtiyaçlarının karşılanması ve çevresel etkilerin en aza indirilmesi için uygun yapı malzemelerinin ve teknolojisinin seçimi çok önemlidir. Bu çalışmanın amacı, Yaşam Döngüsü Değerlendirmesi (YDD) metodolojisini kullanarak beşikten kapıya yaklaşımıyla prekast beton duvar ve tuğla duvar üretiminin çevresel etkilerini karşılaştırmaktır. Bu çalışmada, ISO 14040 ve 14044 standardlarına göre SimaPro 9.2 yazılımı kullanılarak YDD uygulanmıştır. Yaşam döngüsü etki değerlendirmesi için CML-IA baseline yöntemi ve Ecoinvent veri tabanı kullanılmıştır. Elde edilen sonuçlar, abiyotik tükenme ve deniz suyu ekotoksisitesi hariç tüm etki kategorilerinde tuğla duvarın prekast beton duvardan daha iyi çevresel performansa sahip olduğunu ortaya koymuştur. Prekast beton ve tuğla duvarın m2 başına küresel ısınma potansiyeli sırasıyla 2.35E+02 kg CO2 eq. ve 2.10E+02  kg CO2 eq. olarak hesaplanmıştır.

Comparative Life Cycle Assessment of the Environmental Impacts of Precast Concrete and Brick Walls

Öz

There is an increasing interest in assessing the environmental impacts of construction materials and their components in recent years. By considering these environmental impacts, the selection of suitable construction materials and technology is crucial for satisfying user needs and minimizing environmental impacts. The aim of this study is to compare the environmental impacts of precast concrete wall and brick wall production with cradle to gate approach by using Life Cycle Assessment (LCA) approach. In this study, LCA was applied based on ISO 14040 and 14044 by using SimaPro 9.2 software. CML-IA baseline method and Ecoinvent database was used for the life cycle impact assessment. The obtained results revealed that brick wall has better environmental performance than precast concrete wall in all impact categories except abiotic depletion and marine aquatic ecotoxicity. The global warming potential of the precast concrete and brick wall per m2 were calculated as 2.35E+02 kg CO2 eq. and 2.10E+02  kg CO2 eq, respectively.
