Smart demand controlled ventilation

Problem Addressed
To maintain indoor air quality, traditional ventilation systems typically dilute indoor air pollutants with relatively cleaner outdoor air. However, this approach is energy-intensive, as it requires pumping large volumes of outside air into a building, which then must be conditioned for temperature and humidity. Efficiently improving Indoor Air Quality (IAQ) is crucial for maintaining occupant health and well-being. Although replacing existing HVAC systems can address IAQ issues, this solution is often costly, damaging, and disruptive.
Case Study
University College Cork has been using Rensair air purification for more than 12 months to provide a good indoor air quality environment in some of their poorly ventilated buildings across the university’s campus. Rensair offered the university its SDCV solution, which optimises existing mechanical ventilation with Rensair air purification. SDCV delivers excellent IAQ whilst also significantly reducing a building’s energy consumption and carbon emissions. SDCV was installed in the buildings, and data was recorded with respect to IAQ and energy consumption. Already excellent IAQ was maintained, but significant energy savings were achieved with SDCV, leading to carbon footprint reductions.
Achievements:
- A 47% reduction in energy consumption
- A 45% reduction in CO2e
