How to prevent high humidity levels in the workplace

Kristoffer Jensen

Moisture is invisible, but its consequences are anything but. Too much moisture in the office can lead to mold, poor indoor air quality and employee dissatisfaction. And it doesn't stop there – moisture can also damage buildings, equipment and ultimately your finances. That's why it's crucial to take moisture prevention seriously, whether you're a business leader, a facility manager in the public sector or a parent concerned about the health of children in institutions.

In this article, we guide you on how you can effectively prevent moisture problems in office environments - based on Danish recommendations and with an eye on both well-being and sustainability.

Why is moisture a problem in the office?

Imagine the office as a living organism. When moisture enters and is not managed, systems begin to fail. Dark spots appear in the corners, the air becomes heavy, and employees may complain of headaches, fatigue, or allergy-like symptoms. According to the Danish Health Authority, mold and high humidity can have a negative impact on health – even if it is not always visible.

The problem with moisture is that it rarely comes alone. It often brings a cocktail of problems with it: reduced concentration, increased sick leave and deteriorated building condition – all factors that affect both well-being and the bottom line.

The most important steps to prevent damp in the office

Fortunately, there are a number of concrete measures you can take to keep the moisture at bay. Here are the most important – and most effective – methods, based on Danish authorities' recommendations and practical experience.

1. Ensure effective ventilation

Good ventilation is the key to fighting moisture. When we work, cook, wash our hands or simply stay in a room, we release moisture into the air. Without adequate ventilation, this moisture accumulates, increasing the risk of condensation and mold.

According to research from Aalborg University, it is important to create drafts several times a day – especially in rooms such as kitchens and bathrooms. Using a range hood when cooking and ensuring that the ventilation system is working properly is crucial.

At ÅBN, we work with solutions that make it easy to understand and act on the indoor climate. With our intelligent sensors and intuitive dashboards, air quality and humidity levels become as easy to read as the weather forecast. See, for example, our solution Skyen , which visualizes air humidity in real time.

2. Keep the temperature stable and appropriate

Temperature and humidity are closely linked. When the temperature drops, the relative humidity increases, which can lead to condensation on cold surfaces – a perfect breeding ground for mold. That’s why experts recommend that the temperature in office environments does not fall below 18°C.

A fluctuating or inadequate heating system can be a hidden cause of moisture problems. This is especially true in older buildings or in rooms that are not used regularly. By combining temperature control with humidity data, you can ensure a more stable and healthy indoor climate. ÅBN's solutions make it possible to get an overview of both – and react in time.

3. Avoid drying clothes indoors

It may seem like a small thing, but drying clothes indoors is a major source of moisture. One drying rack with wet clothes can release up to 2 liters of water into the air – and this is quickly noticeable in a closed office environment.

If it is necessary to dry clothes indoors, it should be done in rooms with good ventilation and preferably with a dryer with proper exhaust. However, in offices and institutions, it should generally be avoided altogether.

4. Clean regularly – and thoroughly

Mold spores are naturally found in the air, but they thrive in dust and moisture. That's why good cleaning is essential. Vacuuming with a HEPA filter in particular can make a big difference, as it removes microscopic particles that can otherwise circulate in the air and worsen the indoor climate.

Cleaning is not just about aesthetics – it is an important part of indoor air hygiene. A clean workplace is a healthy workplace.

5. Consider moisture prevention in construction and renovation

If you are facing new construction or renovation, it is important to consider moisture protection from the start. According to knowledge from Aalborg University, bio-based building materials in particular are more susceptible to moisture damage if they are not protected correctly. Therefore, it requires a holistic approach where architecture, material selection and technical solutions interact.

At ÅBN, we collaborate with architects, engineers and developers to consider indoor climate and moisture prevention in the design phase. It's not just about solving problems – but about avoiding them in the first place.

How technology helps you prevent moisture

One of the biggest challenges with damp is that it is often detected too late. By the time there are visible signs such as mould or odour, the damage has already been done. Therefore, it is crucial to be able to measure and understand the indoor climate on an ongoing basis.

ÅBN's technology enables real-time insight into humidity, temperature and CO₂ levels. By visualizing data in a simple and understandable way, both employees and management can act in a timely manner – and together. Our solutions also support behavioral changes , so that everyone in the workplace becomes part of the solution.

What can you do today?

Preventing damp doesn't necessarily require a big investment. Here are some simple steps you can take today:

  • Take a deep breath for 5-10 minutes twice daily
  • Keep the temperature in the office above 18°C
  • Avoid drying clothes indoors
  • Ensure regular cleaning – especially in corners and by windows
  • Consider installing sensors that measure humidity and temperature

By combining these initiatives with technology and awareness, you can create a healthier, more productive and more sustainable work environment.
