| The positive energy effect of using the mechanical ventilation with heat recovery strictly depends on the system operation. This issue is especially significant in residential buildings, where occupants often lack sufficient knowledge and competence regarding the ventilation system. The aim of this study was to analyse how user-defined ventilation schedules influence CO2 level, noise level, annual fuel consumption by the heat source and total operating cost. The analysis was performed for an existing low-energy single-family building in Poland and was based on in-situ measurements and energy simulations. The use of ventilation air flow reduction in night-time compared to the constant air flow resulted in 1–5% reduction in heating and ventilation costs. The use of schedules with occupant absence and night-time reduction resulted in 3–14% cost reduction. Optimized ventilation schedule met CO2 and noise criteria with only a small total cost increase (∼4%) compared to the actual schedule in the building. Whereas a poorly chosen constant high-flow schedule increased heating and ventilation cost by ∼33–38%. The study provides a practical evaluation of simple, cost‑free and easily implementable adjustments to constant-air-flow air handling-unit (AHU) system that can improve user comfort while reducing energy consumption. |
