Which sustainability strategies are commonly considered in PDD?

• A. Energy efficiency, water conservation, material selection, daylighting
• B. Increasing project budget without regard to energy
• C. Focusing on landscaping only
• D. Maximizing interior finishes without regard to energy

Answer: (A)

Understanding sustainability strategies in PDD means recognizing the elements that collectively reduce a building’s environmental footprint across energy, water, materials, and occupant comfort. Energy efficiency targets lower overall energy use through a well-sealed building envelope, efficient mechanical and electrical systems, and high-performance equipment. Daylighting uses natural light to cut electric lighting demand while boosting visual comfort and productivity. Water conservation focuses on low-flow fixtures, efficient irrigation, and, where appropriate, water reuse. Material selection emphasizes durable, low-embodied-energy materials with recycled content and responsible sourcing, balancing performance, cost, and environmental impact. Together, these strategies form a holistic approach that is commonly addressed during design development and documentation to meet sustainability goals and performance targets.

Other approaches that emphasize budget without energy considerations, focus only on landscaping, or maximize finishes without regard to energy fail to integrate the full range of sustainability impacts and opportunities that PDD projects typically address.
