Performance zoning can conserve energy by limiting inappropriate site disturbance.

• A. True
• B. False
• C. Not specified
• D. It increases energy use

Answer: (A)

Performance zoning uses outcomes-based standards to guide development, allowing flexibility in how a project meets energy and environmental goals. Limiting inappropriate site disturbance helps conserve energy because it preserves natural features that regulate the local microclimate. Retaining mature trees and vegetation provides shading and cooling, reducing a building’s cooling needs. Avoiding excessive grading and clearing keeps soils intact, supports natural drainage, and reduces heat island effects that would otherwise require more energy for cooling. It also reduces the energy that would be spent on site preparation and infrastructure. Because the approach aims to achieve energy efficiency by protecting the site's natural characteristics, the statement that performance zoning can conserve energy by limiting inappropriate site disturbance is true. The other options run counter to that idea or are ambiguous.
