When we think about workplace health and safety, we often think about obvious hazards—slippery floors, manual handling, electrical safety or emergency procedures.
Yet one of the most overlooked aspects of a healthy workplace is the indoor environment itself.
Over the past 30 years, I’ve walked through offices that looked perfectly clean on the surface. Yet staff were experiencing headaches, fatigue, sore throats or ongoing respiratory irritation. Sometimes the cause was obvious. More often, it wasn’t. Hidden moisture, ventilation problems or indoor contaminants were quietly affecting the workplace without anyone realising.
As a Building Biologist, I’ve visited offices where staff experienced headaches, tiredness, persistent coughs, watery eyes or difficulty concentrating. Sometimes there was an obvious issue such as visible mould or a damp smell. Other times, the building looked perfectly clean and well maintained.
The common question is:
“Can the office itself be contributing to how people feel?”
The answer is sometimes yes.
Most of Our Working Day Is Spent Indoors
Many Australians spend around one-third of their day in the workplace. The quality of the indoor environment can therefore play an important role in comfort, wellbeing and productivity.
When employees regularly report symptoms such as:
- Headaches
- Fatigue
- Watery or itchy eyes
- Runny noses
- Coughing
- Sneezing
- Sore throats
- Difficulty concentrating
it’s worth considering whether the indoor environment should be investigated alongside other possible medical or lifestyle factors.
These symptoms can have many different causes, but indoor environmental conditions are one factor that should not be overlooked.
Air Quality Problems Aren’t Always Obvious
One of the biggest misconceptions is that poor indoor air quality always has a noticeable smell.
In reality, many indoor environmental issues are invisible.
An office can appear clean while still having hidden concerns such as:
- Moisture trapped within building materials
- Previous water damage
- Hidden mould growth
- Poor ventilation
- Dust accumulation
- Air-conditioning systems requiring maintenance
- Volatile Organic Compounds (VOCs) from furnishings, flooring or cleaning products
- Outdoor pollutants entering the building
Without a systematic assessment, these issues may go unnoticed for months or even years.
Looking Beyond the Symptoms
Every building is different.
Rather than assuming mould is always the cause—or that air purifiers are always the answer—we begin by understanding the building itself.
During a Healthy Office Assessment, we look at factors including:
- The building’s history
- Moisture and water intrusion
- Ventilation performance
- Indoor air movement
- Building materials and furnishings
- Sources of dust and allergens
- Occupant concerns and symptom patterns
- Air-conditioning and filtration systems
Where appropriate, targeted testing may also be recommended to help answer specific questions. Testing is not always necessary, and we only recommend it when it is likely to provide meaningful information.
Why Early Investigation Matters
Small building issues often become larger problems if left unresolved.
Identifying concerns early may help building owners and managers:
- Better understand indoor environmental conditions
- Address moisture issues before mould develops
- Improve occupant comfort
- Support healthier indoor air
- Provide useful information when working with landlords, strata managers or maintenance contractors
Most importantly, early investigation can provide clarity instead of guesswork.
Five Signs It May Be Time to Investigate Your Workplace
- Staff feel better after leaving work.
- Musty odours appear after weekends or rain.
- Condensation forms regularly on windows.
- There has been previous water damage or leaks.
- Sick leave or comfort complaints seem to be increasing.
A Practical, Independent Assessment
At Mitey Fresh, our Healthy Office Assessments are carried out from a Building Biology perspective.
Our goal is not simply to identify problems, but to help you understand what may be contributing to your indoor environment and provide practical recommendations to improve it.
Every workplace is unique, and our recommendations are tailored to the building, its occupants and the concerns you’ve observed.
A Healthier Workplace Starts With Understanding Your Building
If you’ve noticed recurring odours, ongoing moisture issues, staff discomfort or concerns about indoor air quality, a professional assessment can help determine whether the building environment warrants further attention.
Healthy buildings support healthier people.
Sometimes the first step is simply knowing what questions to ask.
If you’d like to learn more about our Healthy Office Assessments, we’re happy to discuss your workplace and whether an assessment is appropriate for your situation.
