Pressure

Air pressure measures the force exerted by the air around us and

provides insight into how weather and building conditions affect a space.

What is air pressure?

Air pressure, also known as barometric pressure, is the measurement of the force that air molecules exert on all surfaces, typically expressed in hectopascals (hPa) or millibars (mbar). It changes with weather, temperature and altitude, and the pressure inside a building can differ from the pressure outside. This balance affects how air, heat and moisture move in and out of a building. Measuring air pressure helps building, workplace and facility teams understand how pressure conditions affect ventilation, energy use and indoor air quality.

● THE WHY 

Why does pressure matter?

Air pressure isn't just a weather metric. It influences how air moves through your building, affecting energy costs, building health and other air quality factors.

Optimize HVAC energy use


When pressure inside and outside a building is out of balance, unconditioned air is drawn in through gaps and openings. This forces HVAC systems to work harder to heat or cool spaces, and pressure data helps you understand and reduce this hidden energy loss.
Pressure 2

Prevent moisture damage


In colder months, higher indoor pressure can push warm, humid air into walls and building structures, where it may condense. Over time, this can lead to mold and material damage, making pressure an important factor in preventing moisture problems.
Radon 3

Track radon changes


Pressure changes affect how much radon is drawn into a building from the ground, especially when indoor pressure drops. Monitoring pressure alongside radon helps you understand why levels fluctuate and adjust ventilation to keep exposure low.

Pressure over time

Track air pressure across rooms and buildings in real time. See how weather and building conditions cause pressure to change and follow trends over time, so your team can better understand shifts in radon levels, ventilation and energy use.
