Only recently it was here at labor-abc on the subject ergonomics . From the article showed that an ergonomic workstation is defined not only by the correct posture. What matters is on a variety of aspects that interact and ensure maximum comfort. Besides points as light and volume, it is also the room climate, which plays a major role. What exactly is the indoor climate and how you can influence it consciously, learn in this post.
The different components of the room air
To understand the factor indoor climate, it helps to think about, whereby air is composed in general. Air in terms of weather is a combination of temperature, rainfall, humidity and wind speed. Every aspect affects the climate in his own way and contributes to the uniqueness in. Similarly, even in rooms – or especially in the office. Again, a fantastic climate, that can be in contrast to the weather but actively influenced. The individual components of the room air are:
- air dynamics
- air quality
Each point to be illuminated individually below. This will tell you what values are optimal for the office and what you can do to achieve it.
Let’s start with a value that everyone can judge quite well from us. The temperature determines how it is hot or cold in a room. Although this is a subjective feeling (certainly you know the endless discussions in the office), can be said, what temperature is considered optimal. It is about 21 to 22 ° C .
This value is considered the “happy medium” and optimal when it comes to concentrating on work. If the temperature is above or below, concentration and performance decrease strongly.
As the temperature is controlled, each should be known. Is it too hot, you open a window, it is to be held, then close it and turn the heating if appropriate, additionally.
Note: In the summer it is almost impossible, the temperature to cool down to 22 ° – no matter how hard you and what tools you are using. Since the body is, however, then more accustomed to the heat, the maximum limit for the optimal room temperature rises to 26 ° .
Somewhat more complicated it is, when it comes to the humidity in the room. This is not only difficult palpable or measurable, but also can not be easily regulated. but it is also not impossible.
The ideal value for the humidity in the office is between 40 and 60 percent . To find out how much is the value to you, you should use a weather station. Both too high and too low humidity brings various problems. It is therefore important to constantly have a look at this value.
If the humidity is too high , which favors the formation of mold, which in turn lowers the air quality significantly. The consequences are health problems that manifest themselves especially in asthmatics and allergy sufferers.
If the humidity is too low , which also has an impact on health. It means namely that the mucous membranes of the employees in the office quickly dry out and thus are more susceptible to pathogens. This also spread better than excessively moist than dry air.
Tip: A low humidity in the office you recognize, among others, increased electric shock due to electrostatic charge.
In order to regulate the humidity, there are several possibilities. The following table provides an overview:
|Measures against high humidity||Measures against low humidity|
|Use of dehumidifiers||Use of humidification|
|leave wet umbrellas in corridor / WC||Water cup on the heating|
The air dynamics
Surely you know the saying “Here is the air” and also know that he is to understand anything but positive. If you literally comes to a halt air, it is high time to act. To maintain a good indoor climate in the office, the air has to move. How it works? Simple: By opening and ventilate the window. However, there is to follow a few rules.
The rules of proper airing
- Several times a day for a short time, release (= airing)
- Windows let tilted in winter not permanent (wall cools, condenses water, mold arises)
- Fresh air is better than artificial air-conditioning
- Cross ventilation produces a particularly high air dynamics (this is diagonally opposite window)
- But beware of the train, which arises from the fact!
When air at a rate of more than 0.2 m / s to move, is of a harmful train the speech. This value should be avoided. Close the window when they realize that it attracts. The optimum air dynamics is incidentally between 0.1 to 0.15 m / s .
The air quality
According to workplace regulations must in the office ” sufficiently conducive to health breath exist”.Sounds at first obvious – but what exactly is the “health conducive” to understand?
The quality of the air is influenced by the following factors:
- oxygen content
- Pollutants (for example, furniture and floor coverings)
- mold spores
Whether the air quality in the office is good or bad, you can usually check based on your wellbeing. Fatigue, difficulty concentrating, headaches and related symptoms are frequent indications that the air quality is too bad. It is then high time to carry out a change of air.
Another effective method for improving the indoor climate is the use of green plants. This not only produce oxygen and increase the humidity, but can also be understood as a kind of filter system for the air.Particularly recommended as dracaena, the weeping fig and the room Linde apply.
Unfortunately it is very complicated to measure the air quality so and so the situation in most offices is unclear. Add to this that there are no uniform rules are defining the optimum air quality. Here it is primarily important to pay attention to his personal feelings and prophylactically to air periodically.
Tip: If you spend for professional reasons much time indoors, it is necessary, a daily dose of fresh air in nature pick. Modern man holds too much on in buildings.

Air Conditioning: Blessing or Curse for indoor climate?
Especially in summer, the air conditioning in many offices a real relief. It supplies the room with wonderful fresh air and brings the latter are also in motion. So sounds as would air systems an asset to any indoor climate.
Unfortunately, it is so that air conditioners also bring a number of disadvantages:
- Too strong draft, which can cause tension
- For cold air, which ensures that employees freeze
- For dry air, which dries out the mucous membranes
- Excessive distribution of pathogens (the light due to the dry air game have)
Generally it can be said that air conditioners represent a health hazard. Possible diseases range from a harmless cold up to the dangerous pneumonia. Nevertheless, the plants are indispensable in some cases.This is especially true in large offices and buildings that have few and / or small windows. Then an air conditioner can be a very great blessing.
Sick Building Syndrome: If poor indoor air causes illness
If all guidelines and recommendations are disregarded and reside people very often and long in an enclosed space, there is a risk of Sick Building Syndrome . The name may well be taken seriously: buildings, or the poor indoor climate that prevails in them can make you sick. The sick building syndrome manifested by classical symptoms such as:
- Fatigue / exhaustion
- a headache
- difficulty concentrating
- irritated mucous membranes
- increased irritability
The good news: The symptoms disappear quickly after leaving the building and fresh air has snapped. The trigger for the Sick Building Syndrome , the poor indoor climate in general and pollutants, contaminants, fumes and stress are in particular. Also, increased noise and stressful light conditions, the features of thesick building syndrome have become more prominent.
The optimum indoor climate as an important aspect of ergonomics is a subject with which every company should address. What is your experience with it so far? Plays the indoor environment a major role in your office or it is mostly being ignored? We hope to actively deal after this post so more people.
