Mixed Mode Features & Benefits

• Substantial energy savings
Studies by Brunel University in March 2005 showed that a Passivent Mixed Mode cooling system can provide as much as a 41% energy saving compared to a traditional mechanical ventilation system.

• Future-proofing buildings against climate change
A building that can adapt to a wide range of requirements is more likely to provide enduring value to its owners and occupiers and reduce environmental impact.

• Potential Class A Energy Performance Certificate
The energy saving requirements of building Energy Performance Certificates (EPC) and Building Regulations Part L will continue to get more onerous. Mixed mode is an intelligent solution to regulatory compliance in energy saving. Studies by Environmental Design Services Limited (EDSL) show that a Class A Energy Performance Certificate rating was achieved at the Mitsubishi Electric HQ building in Hatfield after a Passivent Mixed Mode cooling system had been installed.

• Intelligent control
Passivent and Mitsubishi Electric have developed an intelligent controller to realise the full comfort and energy savings of a mixed mode strategy.

• Unrivalled occupant satisfaction
Mixed Mode can provide improved indoor air quality, resulting in fewer incidents of sick building syndrome. Occupants are also provided with their own local control, increasing perceived comfort levels.

• Reduced costs
Reduced operating costs can be achieved due to lower energy consumption and lower maintenance requirements.

• Suitable for new and refurbished buildings
The system can be used in both new and existing building stock, and for most commercial and similar buildings.

• All-round improvement
CIBSE (AM13:2000) explains that the mixed mode concept can frequently provide more cost-effective, adaptable, lower energy, comfortable, future-proof buildings.
