LEED AP Building Design and Construction (BD+C) Practice Exam

Which of the following components is focused on in energy recovery systems?

1. Structural design

2. Water supply

3. HVAC efficiency

4. Ventilation air management

The correct answer is: HVAC efficiency

Energy recovery systems are primarily aimed at improving the efficiency of HVAC (Heating, Ventilation, and Air Conditioning) systems. The correct focus on HVAC efficiency relates to the ability of these systems to reclaim and reuse energy that would otherwise be lost, particularly when conditioned air is exhausted from a building. By incorporating energy recovery systems, the HVAC design can capture exhaust air's thermal energy and transfer it to incoming fresh air, thereby reducing the load on heating and cooling systems. This not only enhances energy efficiency but also contributes to lower operational costs and improved indoor air quality. Consequently, focusing on HVAC efficiency aligns with the goals of energy recovery systems and overall building performance. Other aspects such as structural design, water supply, and ventilation air management are important in the overall design and function of a building, but they do not focus specifically on the energy recovery aspect of HVAC systems. Structural design pertains to the physical support system of a building, water supply involves systems for potable and non-potable water, and ventilation air management addresses the flow and quality of air within a space without the specific emphasis on energy capture.
