Advantages of Installing Demand Control Ventilation Systems

Demand control ventilation gives residents the appropriate amount of fresh air and enhances indoor air quality. Energy savings are achieved with sophisticated airflow management (including demand control ventilation) if there is a minimal requirement for ventilation, which can be more than half the time.

On the other hand, more ventilation is required to remove the pollution swiftly while doing an activity that produces indoor air pollution. These activities can be cooking, taking a shower, or even releasing odorous metabolic components.

Advantages of chilled beam Demand Control Ventilation:

Demand control ventilation allows continuous, automated optimization of heating use and indoor air quality. Every ventilation system created by EB Air Control Inc is based on this chilled beam with a demand-control ventilation approach. It offers several advantages for the system’s operation and is highly beneficial for occupant comfort.

Improved air recirculation for increased comfort

Demand-controlled ventilation systems significantly improve indoor air quality. They deliver the greatest airflow to the areas that need it the most. An inhabited main room has higher relative humidity, which causes the air inlets to open wider to improve circulation and remove stale air. Water vapor emissions are a byproduct of activity in wet areas (such as the kitchen, bathroom, and toilets). When the relative humidity rises, the exhaust units open more widely, enhancing airflow and hastening the removal of pollutants from the air.

Safeguarding against moisture

For instance, breathing and human activity in the kitchen or shower can increase relative humidity. It results in harmful condensation where mold can grow. Humidity-sensitive exhaust devices are swiftly open to remove excess moisture and prevent condensation when the relative humidity rises alarmingly.

Reduced and regulated heating usage

A significant portion, up to 50%, of the heat losses in a home are frequently attributed to ventilation. While most conventional ventilation methods have this characteristic, EB Air Control Inc systems automatically reduce airflow in unoccupied spaces to maintain heat in buildings and rooms.

Additional Advantages of Chilled Beam Demand Control Ventilation

Demand-controlled ventilation shows several secondary advantages from the lowering of average airflow in addition to combining indoor air quality and energy savings optimization:

  • Lower average exhaust fan power usage due to demand control

Demand-regulated ventilation systems enable the exhaust fan to operate much below the maximum airflow, hence at very low power, by lowering the average airflow rate.

  • A reduction in the filter, air duct, and terminal clogging

The demand control ventilation system’s inherent decreased airflow, which is inversely proportional to the total air volume introduced by the ventilation system at any moment, reduces the total number of particles that might clog the system’s components. This means that the power consumption of the demand-regulated exhaust fan can lessen the need to maintain air ducts and filters (where these have been employed) (when the presence of filters).

  • Exhaust fans with demand management have a longer lifespan.

Demand control ventilation allows for a reduction in the demands imposed on the exhaust fan. It increases its longevity by lowering average airflow over the year. This is because the power at which the exhaust fan operates—directly correlated to the need for an average ventilation system air—determines how long it will last.

  • More pressure and airflow are available for terminals

The airflow modulation at the different vents of a collective air ducting system that either serves a single home or several residences allows for the avoidance of overstuffing the air ducts with excessive airflow rates, as would be the case with a constant airflow ventilation system.

As a result, the spaces that require less airflow are freed up in the air ducts for the spaces that demand more ventilation. These may therefore gain from demand-controlled ventilation, from the air ductwork’s full pressure and flow capacity, with losses in the ductwork being optimized and decreased.

  • Air ducts were shrunk to save crucial floor space.

Demand-controlled ventilation can reduce ventilation ductwork size by modulating airflow. This is because not all exhaust vents operate at maximum capacity simultaneously in a collective system. By using smaller air ducts, it may be possible to reduce the amount of floor area needed for ducting.


In both new and ancient buildings, EB Air Control Inc. installs DCV. It may be put there regardless of whether a building has a BMS. They are compatible with most HVAC systems. It can adjust ventilation depending on changes in occupancy, interior and outside conditions, and weather forecasts.
