Which energy design strategy does BERDE emphasize to improve efficiency?

• A. Oversized HVAC systems with high energy use.
• B. Relying exclusively on fossil fuels.
• C. Passive design with orientation, shading, and insulation.
• D. Narrow windows with minimal shading.

Answer: (C)

The main concept tested is energy efficiency achieved through passive design strategies that reduce a building’s energy demand before relying on mechanical systems. BERDE emphasizes shaping the building and its envelope to work with the local climate, not against it. By choosing an appropriate orientation, you can maximize beneficial solar gains in the right seasons and minimize unwanted heat in others. Effective shading controls keep cooling loads down by preventing excessive solar heat gain during hot periods. Good insulation reduces heat transfer through walls and roofs, stabilizing indoor temperatures and cutting the need for heating and cooling. Together, these passive design elements lower energy consumption and improve comfort, which is why this approach is central to BERDE’s guidance on efficient design. Why this stands out: relying on passive design helps achieve energy savings upfront, so active systems don’t have to work as hard or as long. In contrast, oversized HVAC systems waste energy and increase costs; relying exclusively on fossil fuels misses BERDE’s sustainability and efficiency goals; and using narrow windows with minimal shading can hinder daylighting and thermal performance, often leading to greater energy use for lighting and cooling.
