HRV

Heat Recovery Ventilation (HRV) systems improve indoor air quality by providing fresh air and capturing heat from exhaust, enhancing energy efficiency. The ideal HRV rate depends on building size, occupants, and specific ventilation needs. HRVs work by exchanging heat between exhaust and incoming fresh air through a heat exchanger, reducing pollutants and improving comfort. Effectiveness depends on design, climate, building insulation, and air-tightness. HRV systems can reduce heating and cooling energy use by 30% to 60%.
