Passive Ventilation for Commercial Buildings


Ventilation and Air Conditioning place the largest energy load on any typical commercial building. According to CIBSE guide B, a typical office building with standard ventilation and air conditioning uses 226kWh/m2 of electricity, with 109kWh/m2 dedicated to fans (60kWh/m2), cooling (31kWh/m2) and humidification (18kWh/m2).

By comparison, a typical naturally ventilated office uses 85kWh/m2, over 60% less electricity overall, mostly due to the reduction in fan, cooling and humidification demand (down to 10kWh/m2).

Our non-domestic (commercial) passive ventilation with heat recovery product, the Ventive C provides dependable natural ventilation with heat recovery at an average rate of 100 litres per second (wind speed of 4m/s). It naturally removes stale air from classrooms, wards or office spaces and supplies fresh, pre-warmed air in return.

The large heat exchanger, designed specifically for low airflow resistance, ensures the continuous supply of fresh air with minimum heat loss during winter and minimum heat gain during the summer. Besides the health benefits of fresh air, Ventive C will save up to 4,000kWh of heat and 600kWh of electricity when compared with non-conditioned HVAC, and up to an extra 5,000kWh of electricity when displacing Air Conditioning.
