8.2.13 (HL)—Green architecture

Green architecture reduces construction and operating harm through material choice, passive design, energy and water efficiency, and circular construction.

Named example—Arabic wind-tower houses (barajeel) use vernacular knowledge and building form to capture and direct airflow for passive cooling, potentially reducing mechanical cooling demand in a suitable hot, dry climate.

Evaluate sourcing, construction, orientation, climate fit, indoor comfort, maintenance, safety, cultural fit, operational energy and end-of-life recovery against a realistic alternative.

A barajeel is effective only where airflow, geometry and use support ventilation; verify measured comfort and energy outcomes rather than assuming tradition guarantees performance.

Natural, traditional, bio-based or recycled is not a lifecycle verdict by itself.
