testo explains the importance of indoor air quality and why monitoring
of the building is necessary to safeguard the health of its occupants.
Poor indoor air quality can
damage a building
At a simplistic level, HVAC units in buildings warm the air in winter,
and cool it in summer. However, HVAC systems play an important role in keeping
the atmosphere within a structure safe and comfortable for the people who work or
reside in it.
The indoor air quality of a building depends on a lot more than just
temperature or humidity factors. While many of these problems can be eliminated
during the construction process, a correctly-functioning HVAC system is
necessary to ensure they don’t return. HVAC systems should, therefore, be monitored
regularly using refrigeration gauges to
keep them running in optimal condition.
What affects indoor air quality?
Indoor air quality is assessed on the basis of the presence (or absence)
of contaminants in a building’s atmosphere. Monitoring indoor air quality can
reveal the levels of various gases in the building’s interior environment, with
carbon dioxide and ozone being two of the most common. Though harmless in small
quantities, any build-up of these gases in a closed atmosphere as a result of poor
ventilation or lack of air movement can cause irritation and serious health
There are other indicators of poor indoor air quality that reflect the condition
of the building’s health. A prevalence of dust mites, strange odours or
microbial contaminants such as fungi and mould can make the structure unhealthy
and cause discomfort to people living or working in the building.
What happens if indoor air
quality isn’t monitored?
Contaminated indoor air can cause a number of
illnesses including irritated eyes, nose or skin as well as an increased
likelihood of coughing, sneezing, dizziness and nausea. Higher contamination
levels can place residents or occupants at risk of developing long-term illnesses.
These include the Sick Building Syndrome, where the above symptoms manifest in
an individual following long-term exposure to the poor quality atmosphere in
the building, resulting in serious illness.
