Are energy-efficient homes better for indoor air quality and health?

Energy-efficient homes are widely recognised for lowering power bills and reducing environmental impacts, but they also play a significant role in improving indoor air quality and overall health. A well-designed, energy-efficient home is built to minimise air leaks while maintaining consistent ventilation, which helps control moisture, reduce mould growth, and limit the entry of outdoor pollutants such as dust, pollen, and exhaust fumes.

Modern energy-efficient designs use high-quality insulation, airtight construction, and advanced ventilation systems that continuously replace stale indoor air with fresh, filtered air. This controlled airflow reduces allergens and airborne irritants, creating a healthier living environment, particularly for people with asthma, allergies, or respiratory sensitivities. Homes designed by experienced passive house builders in Melbourne often go a step further by integrating mechanical ventilation with heat recovery, ensuring fresh air circulation without sacrificing thermal comfort or energy savings.

Energy-efficient materials and low-emission building products help reduce exposure to harmful volatile organic compounds (VOCs) commonly found in traditional construction. This leads to better indoor air quality, improved sleep, fewer respiratory issues, and enhanced day-to-day comfort for occupants. By prioritising efficiency and air control, these homes support both physical wellbeing and long-term sustainability.
