What does evidence-based design focus on in architecture?

• A. A method for reducing project cost through value engineering.
• B. A process for selecting furniture finishes.
• C. Architecture using the best available science to affect a desired outcome.
• D. A standard for building code compliance.

Answer: (C)

Evidence-based design in architecture means making design decisions grounded in the best available research and data to achieve specific outcomes for occupants and building performance. Instead of relying on tradition or aesthetics alone, it uses scientific findings, post-occupancy evaluations, and measurable performance to guide choices about lighting, acoustics, ventilation, space layout, and more. This approach aims for real improvements in health, comfort, productivity, safety, and energy use, by linking design decisions to proven outcomes.

It's not primarily about cutting costs through value engineering, selecting finishes based on appearance alone, or merely meeting building codes; those are separate considerations. Evidence-based design seeks to justify decisions with evidence about how people actually experience and use the space.
