Article Citation - WoS: 15Citation - Scopus: 20Redesigning for Disassembly and Carbon Footprint Reduction: Shifting from Reinforced Concrete to Hybrid Timber–Steel Multi-Story Building(MDPI, 2023) Mauricio Morales-Beltran; Pınar Engûr; Ömer Asım Şişman; Gizem Nur Aykar; Şişman, Ömer Asım; Morales-Beltran, Mauricio; Engür, Pınar; Aykar, Gizem NurTo reduce carbon emissions holistic approaches to design plan and build our environment are needed. Regarding multi-story residential buildings it is well-known that (1) material choices and construction typologies play a fundamental role in the reduction of carbon footprint (2) shifting from concrete to timber will reduce significantly the carbon footprint and (3) a building designed to be disassembled will increase the potential of achieving zero-carbon emissions. However little has been said about the consequences of such shifts and decisions in terms of building architecture and structural design especially in seismic-prone regions. In this study an existing 9-story reinforced concrete (RC) multi-story residential building is redesigned with cross-laminated timber floors and glue-laminated timber frames for embodied carbon reduction purposes. Firstly the reasons behind design decisions are addressed in terms of both architecture and structure including the incorporation of specially steel concentrically braced frames for seismic-resistance. Then the outcomes of life cycle assessments and pushover analyses show that the RC residential building emits two times more carbon than the hybrid steel-timber residential building and that while the hybrid building’s lateral load-capacity is less than in the RC building its deformation capacity is higher. These results highlight the relevance of considering the carbon footprint in combination with the design decisions which seems to be the key to introducing circular projects in seismic-prone areas. © 2023 Elsevier B.V.

Marschalko , I. Yilmaz , M. DrusaThe construction sector plays a significant role in the high energy consumption waste generation and carbon emissions. To reduce these emissions we must begin by changing the way we design plan and build our environment. This research study revolves around the idea of applying circular design principles to the built environment whereby buildings are conceived as recyclable and reusable banks of materials. We focused on applications within the Turkish context because building sector is responsible for more than 35% of the country's total final energy consumption. The selected building is an 9-story RC building located in Izmir redesigned with CLT floors and GLT columns and beams offering the possibility of a design strongly resembling the original architecture. The lateral-force resisting system is based on specially concentrically braced frames and the architectural implications of choosing this system are discussed. Fire design was considered to provide practical guidelines for the design of timber buildings in Turkey. Evaluation parameters include easiness of construction price potential for disassembly mass and carbon footprint. Each apartment was designed different size for different users' demand and adaptable for different future scenarios in line with the idea of flexible spaces. From the lessons learned from the design process the relevance of considering the carbon footprint in combination with the design decisions seems to be the key to introduce circular projects in places like Turkey. This is because not all decisions are based on achieving the lower embodied carbon factor but on those that increase the potential for disassembly throughout the life-span of the building. © 2023 Elsevier B.V.

Bu beton çeşidi, çimento, cam elyafı ve çeşitli yapı kimyasallarının karışımıyla elde edilir, son derece sağlam ve dayanıklıdır. Geleneksel betonlara kıyasla, basınç, bükülme ve çarpma dayanıklılıkları oldukça yüksektir. Bu özellikleri sayesinde günümüzde bina cephelerinde tercih edilen bir seçenek haline gelmektedir. Günümüzde peyzaj ve kent mobilyaları, dekorasyon elemanı, yapı malzemesi, altı yapı - üst yapı elamanı ve sık olarak cephe kaplama malzemesi olarak farklı alanlarda ve fonksiyonlarda GRC kullanımı görülmektedir. Bu tezde cephe sistemlerinde GRC malzemesinin rolü, enerji performans ve tasarım açısından değerlendirilmektedir. Bu bağlamda tuğla ve sıvadan oluşan temel bir duvar tipine GRC ve farklı parametreler eklenerek enerji simulasyonu yapılmaktadır. Bulgular, GRC'nin farklı strüktür ve izolasyon malzemeleriyle entegre edildiğinde önemli bir enerji tasarruf potansiyeli sunduğunu ve bu nedenle çağdaş mimari için uygulanabilir bir seçenek olduğunu göstermektedir. Oluşturulan bu duvar tipi kombinasyonlarından enerji verimliliği açısından en efektif sonucu veren senaryoyu içeren bir yapı örnek çalışma olarak ele alınmaktadır. Örnek yapı yardımıyla cephe malzemesini üretim aşamasından bakım aşamasına olan süreç mimari zorlukları ve dikkat edilmesi gereken hususlarıyla aktarılmaktadır. Amaç literatürde GRC'nin uygulama detayları ve enerji verimliliği açısından eksik olan boşluğu doldurmak ve tasarımcılar için bir rehber oluşturmaktır.
