How Artificial Intelligence Enhance Ventilation System Controls

Construction Tech Review | Tuesday, April 19, 2022

HVAC systems can use a lot of energy; therefore, passive systems should be used whenever practical.

FREMONT, CA: HVAC systems account for most of the energy consumed in residential and commercial buildings. As a result, energy efficiency efforts focused on HVAC can result in significant cost reductions. However, energy-saving HVAC renovations should not degrade the interior environmental quality since this might result in discomfort and health problems. This also has a detrimental effect on productivity in work environments.

Artificial intelligence has significant potential in the HVAC industry, as it can increase both energy efficiency and indoor environmental quality. AI can optimize airflow, temperature, and humidity variables, preserving air quality while consuming the least amount of energy possible.

Controlling HVAC Systems: A Technical Challenge

Controlling an HVAC system properly is challenging due to the constant change in building conditions. Take into consideration the following:

  • Outdoor temperatures constantly change, affecting the heating or cooling required to maintain a comfortable indoor temperature.
  • Buildings are constantly being entered and exited, which affects ventilation requirements and temperature regulation.
  • Indoor activities also affect HVAC requirements. For instance, a commercial kitchen requires more ventilation and cooling than a similar-sized office.

A building's ventilation, heating, and cooling requirements are constantly changing. Only an intelligent control system can process all of this data in real-time and automatically adjust the HVAC system. Due to the fluctuating operating conditions, an HVAC system with manual controls cannot achieve peak performance.

Smart Ventilation System Controls

It takes less energy to run an air handler than an air conditioner or heater. However, a building's heating and cooling requirements are influenced by the exterior airflow it receives.

Heating a bigger volume of cold air requires more energy, for example, if a ventilation system boosts airflow in the winter.

Air conditioning works the same way when the ventilation system is turned up in the summer.

Many ventilation systems run at maximum efficiency at all times, and as previously stated, this amounts to a significant waste of energy. Ventilation controls equipped with artificial intelligence (AI) can identify the ideal airflow for a building. Tracking occupants and significant air contaminants such as VOCs or particle matter are also possible thanks to the system.

Overventilation is a waste of energy, while underventilation is harmful to the air quality in the home. They are both prevented by an AI-enabled ventilation control. Only one thing is required: the ventilation system must never fall below the minimum airflow level mandated by local building regulations.
