What is the purpose of site-specific performance criteria in design development?

• A. To ensure the building meets client goals regardless of local conditions.
• B. To ensure the building meets local conditions, climate, and regulatory expectations while achieving client goals.
• C. To maximize architectural novelty without regard to performance.
• D. To simplify procurement by using generic standards.

Answer: (B)

Site-specific performance criteria anchor design decisions to the actual place. They ensure the building responds to local climate, site conditions, and regulatory requirements while still meeting the client’s goals. By setting targets for energy use, daylighting, moisture control, indoor environmental quality, and structural performance that reflect real conditions, the design team can evaluate options and make decisions that deliver predictable performance in that location. This integrated approach supports enclosure, systems, and site work working together to meet both regulatory expectations and client objectives. Focusing only on client goals without considering local conditions can lead to poor performance or noncompliance, while chasing novelty or using generic standards ignores the realities of the site and lifecycle performance.
