This study proposes a concept and workflow for solar, context-adaptive and reusable façades. Integrating solar control with parametric facade design, the workflow enables envelopes to adapt to urban context changes while promoting circularity. 

The method was tested through simulations, assessing daylight, glare, energy and circularity in changing urban scenarios. A Solar Circularity Indicator (SCI) was introduced to track façade alterations and reuse. In the 100m new obstruction scenario, 79% of facade modules were maintained, while 29% of altered modules were reused, yielding an 85% SCI.

The solution provided 2% more useful daylight than glazed façades and 11% less glare. The workflow provides a framework for circular, performance-based designs that preserve aesthetics and adaptability.
