Abstract

This study introduces a pilot framework for evaluating two facade systems under circular design principles, integrating multi-criteria and time-based assessments. The framework assesses cost, environmental impact, and life cycle assessment (LCA) performance over a 30-year building lifecycle, including maintenance and material recovery potential. Facade A (aluminum panel) and Facade B (timber-based modular system) are compared using a simplified scoring approach. Results indicate that timber-based facades outperform aluminum in environmental and LCA metrics, while cost differences are minimal. The pilot framework demonstrates a practical tool for early-stage design decision-making, highlighting key trade-offs between economic and environmental objectives. This study is intended as a pilot and exploratory application rather than a comprehensive quantitative assessment. Findings suggest that simplified multi-criteria and time-based evaluations can support architects in implementing circular design principles in facade selection, providing a foundation for more comprehensive assessments in future research.

Özet

Bu çalışma, döngüsel tasarım ilkeleri kapsamında iki cephe sisteminin değerlendirilmesine yönelik, çok kriterli ve zaman boyutlu bir pilot çerçeve önermektedir. Çerçeve; maliyet, çevresel etki ve yaşam döngüsü değerlendirmesi (LCA) performansını, bakım süreçleri ve malzeme geri kazanım potansiyelini de içerecek şekilde 30 yıllık bir bina yaşam döngüsü üzerinden ele almaktadır. Alüminyum panel sistemden oluşan Cephe A ile ahşap esaslı modüler sistemden oluşan Cephe B, basitleştirilmiş bir puanlama yaklaşımı kullanılarak karşılaştırılmıştır. Elde edilen sonuçlar, ahşap esaslı cephe sistemlerinin çevresel etki ve LCA performansı açısından alüminyum sistemlere kıyasla daha üstün olduğunu, maliyet açısından ise iki sistem arasında belirgin bir fark bulunmadığını göstermektedir. Önerilen pilot çerçeve, erken tasarım aşamalarında karar verme süreçlerini destekleyen pratik bir araç sunmakta ve ekonomik ile çevresel hedefler arasındaki temel ödünleşimleri ortaya koymaktadır. Bu çalışma, kapsamlı nicel bir değerlendirmeden ziyade pilot ve keşif niteliğinde bir uygulama olarak tasarlanmıştır. Bulgular, basitleştirilmiş çok kriterli ve zaman boyutlu değerlendirmelerin, mimarların cephe seçimi süreçlerinde döngüsel tasarım ilkelerini uygulamalarını destekleyebileceğini ve gelecekte yapılacak daha kapsamlı çalışmalar için bir temel oluşturabileceğini göstermektedir.
