Understanding the Life Cycle Stages of Building Products: A Deep Dive

Published by firstgreen on

In our quest for sustainability and efficient energy utilization, it becomes crucial to understand the life cycle stages of building products. This not only aids in informed decision-making but also paves the way for efficient resource utilization, ensuring a sustainable future.

Let’s delve into these life cycle stages, exploring each phase in detail.

The Life Cycle Stages Explained

The life cycle of building products can be categorized into various stages, each representing a different phase in the product’s journey from inception to disposal. To ensure clarity, let’s break down each phase using a table format:

Life Cycle Stage Description System Boundaries
Product/Manufacture Stage [A1-A3]    
A1: Raw Material Extract/Process/Supply Extraction and processing of raw materials Cradle-to-Gate
A2: Transport Movement of raw materials to manufacturing site Cradle-to-Gate
A3: Manufacture Conversion of raw materials into finished product Cradle-to-Gate
Construction Process Stage [A4-A5]    
A4: Transport to the Site Moving the manufactured product to the construction site Gate-to-Grave
A5: Assembly/Install in the building Integrating the product into the building structure Gate-to-Grave
Use Stage [B1-B7]    
B1: Use/Application of Installed Products How the product serves its function post-installation Cradle-to-Grave
B2: Maintenance Routine upkeep of the product Cradle-to-Grave
B3: Repair Fixing any damages or malfunctions Cradle-to-Grave
B4: Replacement Swapping the product with a new or better version Cradle-to-Grave
B5: Refurbishment Renovation or making product-like-new Cradle-to-Grave
B6: Operational Energy Use Energy consumed during product operation Cradle-to-Grave
B7: Operational Water Use Water consumed during product operation Cradle-to-Grave
End-of-Life Stage [C1-C4]    
C1: Deconstruction/Demolition Taking apart the product from its installed state Cradle-to-Cradle
C2: Transport to Waste Process Moving the product for waste processing Cradle-to-Cradle
C3: Reuse-Recovery-Recycle Repurposing or recycling the product Cradle-to-Cradle
C4: Disposal Final product disposal if not recycled Cradle-to-Cradle
Benefits & Loads Beyond [D] Potential benefits post disposal, like recycling Cradle-to-Cradle
