This On Demand CEU is a recorded presentation from a previously live webinar event. Reusing existing buildings is one of the most effective strategies architects have to reduce embodied carbon and structural steel plays a critical role in making reuse viable, adaptable, and measurable. This course examines how steel supports circular design strategies that extend building life, enable program change, and reduce carbon impacts beyond end-of-life recycling.
Using whole-building life-cycle assessment as a framework, the session explores how retaining and adapting steel structures compares to new construction. Case studies demonstrate how architects leveraged existing steel frames, selective reinforcement, and targeted interventions to achieve substantial embodied carbon savings while delivering new uses, density, and performance. The course emphasizes actionable design decisions architects can make early to preserve value, reduce waste, and document carbon outcomes.
