Energy-efficient homes are designed to minimize energy consumption, reducing environmental impact and lowering utility bills. However, these homes can also have a significant effect on indoor air quality. With tightly sealed windows and insulation, energy-efficient homes limit the flow of outdoor air, which can trap pollutants inside. This can lead to increased concentrations of allergens, volatile organic compounds (VOCs), and other harmful substances.
To counter this, modern energy-efficient homes often incorporate advanced ventilation systems, such as heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs). These systems ensure proper airflow while maintaining energy efficiency, helping to remove stale air and bring in fresh outdoor air without losing heat or cooling. Additionally, using non-toxic building materials and ensuring regular maintenance of HVAC systems can help improve air quality. Overall, when properly designed, energy-efficient homes can offer both energy savings and a healthier living environment.
