How can energy-recovery ventilation systems benefit a home?

Energy-recovery ventilation systems provide significant benefits to a home by recovering energy from exhaust air. These systems are designed to efficiently manage indoor air quality while minimizing energy loss. When stale indoor air is expelled outside, energy-recovery ventilators capture some of the heat or coolness from that air and transfer it to the incoming fresh air. This process reduces the workload on heating and cooling systems, leading to lower energy consumption and improved temperature regulation within the home. This not only enhances comfort for the occupants but also contributes to energy savings, making the home more environmentally friendly and cost-effective in the long run.

In comparison, the other options do not accurately reflect how energy-recovery ventilation systems operate or their primary benefits. Increasing energy consumption contradicts the very function of these systems, which aim to optimize energy efficiency. Filtering debris and preventing pests is more closely related to basic ventilation systems rather than the specific energy recovery function. Similarly, illuminating indoor spaces pertains to lighting, which is not relevant to the operation of ventilation systems.
