This system cleverly monitors and adjusts the indoor environment to suit your needs and preferences. Let’s take a look at how it achieves this minor miracle.

A smart ventilation system uses sensors, controllers and actuators to monitor indoor air quality and energy efficiency. It can automatically regulate the amount, direction and timing of fresh air intake and exhaust based on the indoor and outdoor conditions, the occupancy and the user preferences. A smart ventilation system can also communicate with other smart devices, such as thermostats, humidifiers and air purifiers, to create a comfortable, healthy indoor environment.

Its benefits include:

• Improving indoor air quality by removing pollutants, allergens and odors
• Reducing energy consumption and the owner’s carbon footprint by optimizing the ventilation rate and heat recovery
• Enhancing the comfort and well-being of the occupants with adequate ventilation
• Preventing condensation, mold and noise

How Does It Work?

There are three main components: sensors, controllers and actuators. The sensors measure various parameters of the indoor and outdoor air, such as temperature, humidity and carbon dioxide. The controllers process the sensor data and compare it with the user settings and occupancy data. They then send commands to the actuators, which control the airflow and direction of the ventilation system. There are different types of actuators, including fans, dampers, valves and vents — all designed to adjust the ventilation rate and heat recovery.

Smart ventilation systems also communicate with other smart devices in the home, such as thermostats, humidifiers and air purifiers, to coordinate the indoor climate and air quality.

The system can operate in different modes, such as:

• Constant mode, which maintains a constant airflow regardless of the indoor and outdoor conditions
• Demand-controlled mode, which varies the airflow according to the indoor air quality and the occupancy
• Weather-responsive mode, which adapts the airflow and the heat recovery according to the outdoor temperature and humidity
• User-controlled mode, which allows the user to manually override the settings and adjust the airflow and direction

Can It Be Installed on an Existing Ventilation System?

Yes, a smart ventilation system can be installed on an existing ventilation system as long as it meets some basic requirements.

The existing system must have:

• Ducts that supply fresh air to the living areas and/or bedrooms
• Roof space that’s accessible and has enough room for the smart ventilation components
• A power supply that’s compatible with the smart ventilation system
• A controller that’s compatible or that can be replaced by a suitable alternative

If the existing system meets these criteria, a smart ventilation system can be easily installed by a qualified installer with minimal disruption and cost.

What Are the Perks of a Smart Ventilation System?

A smart ventilation system isn’t just a convenient and intelligent way to control indoor air quality and energy efficiency; it also offers several perks.

• A smart ventilation system can provide you with the optimal level of ventilation and heat recovery according to your preferences and the outdoor conditions. You can enjoy fresh, clean air without feeling too hot or cold or having to endure condensation, mold or noise.
• It can protect you from the harmful effects of indoor air pollution, such as allergies, asthma, headaches and fatigue. By removing pollutants, allergens and odors from the indoor air, a smart ventilation system can enhance your well-being and productivity.
• It can reduce your energy consumption and carbon footprint by optimizing the ventilation rate and heat recovery. You can save money on your heating and cooling bills and contribute to a better environment.
• A smart ventilation system can operate automatically without requiring your constant attention or manual adjustment. You can also monitor and control the system remotely using your smartphone or other smart devices.
