| Abstract | Indoor air quality (IAQ) and health are major areas of concern in northern housing, and are influenced by ventilation. Northern housing experience varying occupancy (overcrowding) and indoor conditions (high indoor activities), leading to higher indoor pollutants and moisture that need to be controlled to avoid mold problems, deterioration of the building and the IAQ. To better address these issues ventilation needs to become smarter and designed to automatically adjust ventilation based on indoor needs. This paper present results from a side-by-side testing of a CO₂-based demand-controlled dual core energy recovery system versus a conventional single core energy recovery ventilator (ERV) using twin houses with simulated occupancies. The results showed that the implemented strategy based on a CO₂ sensor network connected with the dual core ERV unit was simple and efficient to adjust the ventilation for varying occupancy with improved control of the CO₂ concentrations in the test house, ensuring daily mean concentrations below 1000 ppm in the main floor and master bedroom, and below 1200 ppm in bedrooms with closed doors. Compared to low simulated occupancy, power consumption of the CO₂-based dual core ERV increased by 53% during higher simulated occupancy. |
