Natural Ventilation Solutions

The Natural Ventilation Solution The fundamental difference between more commonly used mechanical ventilation and natural ventilation is the use of encapsulated wind power to fully ventilate the building. Our system works on the basis of natural fresh air entering the building through various wall mounted units with modulating control dampers. The air passes throughout the building via a series of grilles and dampers allowing for a controlled environment purely using fresh air eliminating the need for a costly mechanical arrangement. The stale air leaves the building via several roof turrets.


The GDL Intelivent Unit is ideally suited for commercial and educational buildings. This unique design eradicates the ‘cold drop’ effect and allows the unit to work as a front line heating system. The two modulating dampers give added control to the ventilation rate and the front attenuator baffle gives additional noise reduction to the unit.

The unit is ideally controlled by Distech - Controls wireless systems. This system can control up to six Intelivent units and can work via CO2, temperature sensors or simple on-off switches, all wireless. This gives more flexibility, providing user friendly controls which can be operated easily by the occupant. The system can be connected to any existing BMS or internet system, reducing the cost of installing a conventional wired controls system.

Intelivent Advantages

Two section heater battery to give greater control and energy saving.

Heater battery sited at low level to eliminate cold drop (cold air at low level).

Split damper which gives greater control to prevent ‘over ventilation’ and reduces energy consumption.

The units can be controlled by CO2 emissions, temperature sensors or manual override.

Wireless control systems are optional and give significant cost savings over hard wiring.

A single control system can control up to six natural ventilation units.

Optional noise attenuation can further reduce noise levels.

Control systems can be sited remotely, e.g. in the roof space to eliminate misuse.

Adjustable wall sleeve to cover a wide range of wall thickness.

Tamper proof fixings and user friendly design to help prevent wilful damage.
