An eco-friendly and cost effective way to improve air quality, natural ventilation is an often underrated or forgotten solution that could have a huge impact on your building’s internal environment.

We explain more about how natural ventilation works below, along with six key reasons why you should consider installing our advanced control units.Natural-Ventilation-Solutions


Ventilation is vital in any building, as it ensures that the air is kept safe for breathing by allowing air to move in and out, as well as distributing it around the internal space.

At Teal, alongside remote control or switch operated systems, we offer advanced control units to optimise your natural ventilation. You can choose to link these to a range of different climate sensors which will automatically react to rain, wind, internal and external temperatures, smoke, or CO2 levels.Control unit diagram


Natural ventilation systems are a more cost effective and sustainable alternative to standard mechanical ventilation systems. Instead of relying on electricity, they harness natural forces such as wind and temperature changes to cool and heat your building.

There are varying types of natural ventilation, suited to different build configurations and depending on where your windows are situated. These include single sided ventilation, cross ventilation (windows on both sides) or stack ventilation (heat escapes through ventilation points in the roof).Natural Ventilation Diagram

At Teal, our control units can be linked across multiple windows as part of one system, to optimise the effect. Our units operate actuators of 230V AC and 24V DC as part of your natural ventilation system.


One of the key reasons to install natural ventilation is its ability to improve air quality. The system ensures the air in the building is refreshed, with ‘spent air’ with more CO2 moved out, along with any smoke, humidity, heat and smells. This air cycle also helps to limit bacteria and germs from spreading in the space.

Natural ventilation is so important in terms of air quality, that it is part of the Building Regulations Part F, which was updated in 2022.natural-ventilation


1. Control your climate

By implementing natural ventilation and installing control units, you can programme sensors to react to external forces such as wind, temperature or rain. If programmed correctly, this can help to keep the room at a steady temperature and humidity, without the use of air conditioning.

2. Cost effective

By reducing the need for air conditioning and optimising your building’s temperature by harnessing natural forces, the costs of running the building are automatically reduced. Cool air will continue to be circulated, whilst heat will not be lost unnecessarily through windows that have been left open. As well as saving money through temperature control, having a natural ventilation system which optimises natural light will also help to reduce bills, as you won’t need to rely so heavily on electric light.

3. Improve health and safety

By ensuring a constant cycle of fresh air, those in the room will benefit from a healthier environment. If in a workplace, this may well also help to improve employee efficiency. Installing control systems with smoke sensors will additionally help your building to pass safety inspections, as windows can be automatically programmed to open when the sensors are activated.

4. Increase sustainability

By implementing our system controls to complement your natural ventilation system, you will be increasing the sustainability of your building and lowering your carbon footprint, helping to take care of the environment. This is due to the system optimising internal temperature and humidity using natural forces.

5. Optimise on aesthetics

By installing our system controlled actuators as part of a natural ventilation system, even in buildings where windows may be out of reach, windows will continue to open and close as and when required, without the difficulty of having to reach them. This is also ideal for buildings with particularly visually impressive architecture, as this system removes the need for less aesthetic solutions.

6. Increase value

When it comes to selling or valuing your property, the presence of a natural ventilation system, particularly one controlled by sensor-activated actuators, will positively contribute and increase the overall value of the building.
