- Abstract
- The energy consumption evaluates that the optimal ventilation control strategy for energy saving in high-rise residential buildings. Targeting a high-rise residential building unit, it comparatively analyzed the characteristics of energy consumption by cases utilizing the existing method of operating ventilation system in an air conditioning system, the individual ventilation system based on heat recovery ventilators, and the alternative CO2-DCV-based ventilation system control. It estimated the proper supply airflow rate of mechanical ventilation systems required for applying DCV system to high-rise buildings; analyze the variation of contaminant concentration, the change of supply airflow rate for ventilation, and the operation schedule with airflow network simulation; and predict the annual heating/cooling energy consumptions by the set cases in energy simulation. Then, comparing them to the existing system applied to high-rise residential buildings, it quantitatively analyzed the energy saving effects from the application of DCV system to high-rise residential buildings.
