What term describes the process of designers researching past interior projects to learn from them?

• A. Observational research
• B. Evidence-based design
• C. Historical reconstruction
• D. Prototyping methods

Answer: (B)

Evidence-based design uses findings from previous projects and research to inform current design decisions. When designers study past interior projects to learn what worked and what didn’t, they’re applying this approach, drawing on outcomes, measurements, and related research to guide choices about layout, materials, lighting, acoustics, and occupant comfort. This helps improve health, safety, and overall user satisfaction in the space.

Observational research focuses on watching people in real time, rather than extracting lessons from historical projects. Historical reconstruction involves recreating past interiors to study them rather than using past project outcomes to inform new work. Prototyping methods are about creating and testing models or mock-ups to evaluate ideas before full-scale production.
