Introduction to Architecture Decarbonization

What is Architecture Decarbonization?

Decarbonization in architecture refers to the strategic reduction of carbon dioxide emissions associated with buildings. This includes the carbon emissions produced during the construction, operation, and demolition of buildings. It’s a crucial part of the global strategy to combat climate change.

Why Architecture Decarbonization Matters

Buildings are big players in the global carbon output game. In fact, they’re responsible for nearly 40% of global CO2 emissions when you consider both operational emissions (from things like heating and cooling) and embodied emissions (from materials and construction processes). Cutting down these emissions is not just good for the planet; it’s increasingly seen as a necessary step for compliance with international climate agreements and local regulations.

From Then to Now

The architecture industry has not always been focused on sustainability. The modern movement brought about innovations in materials and design techniques that emphasized aesthetics and function, often at the cost of environmental impact.
