As the built environment moves towards more sustainable and circular practices, the role of daylight in these strategies remains an underexplored area of research. This workshop will explore how daylighting principles can contribute to a Circular and Sustainable Built Environment, such as through the reuse of buildings, façade components, windows, and glazing, while considering relationships and impacts on daylight performance and qualities, design process, energy use, and human comfort and health.

Recent research has started bridging this gap, demonstrating how solar-responsive and adaptable façades can optimize daylight while enhancing the circularity of facades in urban environments undergoing urbanization and densification. However, further investigation is needed to understand the interaction between daylight and circular construction practices, including adaptive reuse, reuse of building components, glazing, and material recovery.

Objectives

• Identify various daylight and circular strategies and their interaction/integration.
• Explore the influence of coupled daylight and circularity strategies on building performance, visual comfort, and health effects.
• Discuss daylight properties and qualities of reused buildings, façade components, and glass versus new high-performance buildings and components.
• Identify the next steps and define possible outcomes.
