Reconsidering BIM-LCA Integration for Environmental Assessment and Decision-Support Processes in the Construction Industry

Öz

The construction industry is responsible for a significant portion of global energy consumption and environmental emissions. Life cycle assessment (LCA) is a crucial environmental management tool that analyzes the environmental impacts of the construction industry in an integrated and systematic way, and is vital for building carbon neutral built environments. The BIM integration approach stands out to optimize and support comprehensive LCA processes. This study aims to analyze existing studies in the field of BIM and LCA integration, identify significant gaps in this area, and propose a framework for providing an integrated and systematic perspective on integration. The proposed framework consists of four basic modules. Representative studies on BIM-LCA integration were selected and analyzed in accordance with the developed framework, and the evaluations are explained. The findings indicate a need for environmentally performance-oriented BIM-based decision support mechanisms that support LCA and multi-criteria decision-making processes. Furthermore, it provides a methodological basis for a decision support mechanism for BIM-LCA integration.

Yapı Endüstrisinde Çevresel Değerlendirme ve Karar Destek Süreçleri için BIM-LCA Entegrasyonunun Yeniden Değerlendirilmesi

Öz

Yapı endüstrisi çevresel küresel ölçekte enerji tüketimi ve çevresel emisyonların önemli bir bölümünden sorumludur. Yaşam döngüsü değerlendirmesi (LCA) yapı endüstrisinin çevre üzerindeki etkilerini bütünleşik ve sistematik olarak analiz eden ve karbon nötr yapılı çevre inşa etmek açısından önemli bir çevre yönetim aracıdır. Kapsamlı bir yapıya sahip LCA süreçlerini optimize etmek ve desteklemek için BIM entegrasyon yaklaşımı öne çıkmaktadır. Bu çalışmada, BIM ve LCA entegrasyonu alanında yapılan çalışmaları analiz etmek, bu alandaki önemli boşlukları tanımlamak, ve entegrasyon konusunda bütünleşik ve sistematik bir bakış açısı sunmak için bir çerçeve önerilmesi hedeflenmiştir. Önerilen çerçeve dört temel modülden oluşmaktadır. Temsil niteliğinde BIM-LCA entegrasyonuna ilişkin çalışmalar seçilerek geliştirilen çerçeve doğrultusunda analiz edilmiştir ve değerlendirmeler açıklanmıştır. Bulgular, LCA ve çok kriterli karar verme süreçlerini destekleyen, çevresel performans odaklı BIM tabanlı karar destek mekanizmalarına ihtiyaç olduğunu göstermektedir. Ayrıca, BIM–LCA entegrasyonuna yönelik karar destek mekanizması için metodolojik bir temel sunmaktadır.
