Indoor climate in work rooms

Indoor climate

The indoor climate is an essential environmental factor when designing work systems. A room climate that employees perceive to be comfortable has a positive effect on well-being, health and productivity. If, on the other hand, the indoor climate is perceived as uncomfortable by the employees, exactly the opposite occurs - well-being and performance decline. A room temperature of 12 ° C can be optimal if clothing and work are coordinated with it, while this is not acceptable for offices. Only the complex interplay of many parameters characterizes a climate condition or, with their knowledge, it can be objectively assessed.

The most important climate parameters for feeling comfortable in the workplace are:

  • Air temperature (° C)
  • humidity
  • Air speed
  • Thermal radiation
  • Air pressure
  • physical activity
  • Insulating effect of clothing

Employers must ensure that there are indoor climatic conditions in work rooms that are appropriate for the human organism.

Basically, all rooms of a workplace must be set up sufficiently ventilated according to their type of use.

The indoor climate and its parameters - information on physical parameters, personal factors and air quality from the Federal Institute for Occupational Safety and Health (baua)

Air temperature

TheAir temperature in the work area should not exceed or fall below the following values ​​during the cold season in connection with the maximum air speed depending on the severity of the work:

  • Room temperature 19 ° to 25 ° C, max.air speed 0.10 m / s, low physical stress
  • Room temperature 18 ° to 24 ° C, max.air speed 0.20 m / s, normal physical stress
  • Room temperature at least 12 ° C, maximum air speed 0.35 m / s, high physical strain

Section 28 Coreper

Exceptions and deviations from Coreper climate regulations

The following special cases are dealt with in a decree issued by the Labor Inspectorate:

  • Consideration of the radiation temperature (exception to Section 28 (1) Coreper)
  • Upper limits of the air speed for low and normal physical exertion (exception to Section 28 (3) Coreper)
  • permissible maximum air temperature and air speed in kitchens (specification of § 28 para. 4 Coreper)
  • Permissible maximum air speed in spray painting systems (exception to Section 28 Paragraph 3 Z 2 Coreper)

Exceptions / deviations from Coreper climate regulations

Indoor climate during the warm season

Air temperature

The obligation for employers to take measures against heat at the workplace is set out in Section 28 Coreper. When working with low physical stress, there is an upper limit of the permissible air temperature in work rooms of 25 ° C, with normal physical stress of 24 ° C. In this regard, Section 28 (2) subparagraph 2 Coreper requires measures to be taken during the warm season (= heat is caused by the weather) in order to reduce the temperature as far as possible. Possibilities would be e.g. B. shading by blinds or roller blinds (according to § 8 Paragraph 1 Z 2 Coreper) or ventilation in the morning and evening, if possible also during the night.

There is no obligation to provide air conditioning or air conditioning units.

If compliance with the maximum permissible air temperature is not possible due to the type of use of the work rooms (artificial heat sources, e.g. machines), according to Section 28 (4) no. 1 Coreper, corresponding temperatures must prevail at least in the area of ​​fixed workplaces. If this is not possible either, employers must, in accordance with Section 28 Paragraph 4 Z 2 Coreperother technical or organizational measures take to lower the load, such as B. Shielding from heat-radiating surfaces or reducing the exposure time.


Limit values ​​for the air humidity are only specified for rooms with air conditioning, since in this case the possibility of a technical influence on the level of air humidity already exists (Section 28 (5) Coreper).

In work rooms that are not air-conditioned, occupational health and safety law does not prescribe any limit values ​​for the permissible range of relative humidity; the humidity range recommended by occupational medicine is between 40% and 70%. Coreper does not require any technical measures to be able to regulate the humidity accordingly. Thus, the limit values ​​according to Section 28 (5) Coreper should be aimed for, but no technical facilities (such as air conditioning systems) that guarantee compliance with the limit values ​​are required.


However, if an occupational physician has assessed a health risk for employees, the employer is obliged, according to Section 4 of the ASchG, to determine appropriate risk prevention measures in the course of determining and assessing the risks.

Section 28 Coreper

Tiled stoves - surface temperature

Measures to protect against burns in tiled stoves

The Federal Guild of Hafner, Tile Layers and Ceramists, in cooperation with the Austrian Tiled Stove Association and the Central Labor Inspectorate of the Federal Ministry of Labor, published an information sheet on the subject of "Hot surfaces - measures to protect against burning in tiled stoves".

Air conditioning systems - health effects

Germs in air conditioning systems can affect human health.

"It draws too much!", "It smells musty!", "I'm cold!", "I'm hot!", "It's too loud!", "It makes me sick!".

These or similar complaints from employees who spend most of their working hours near ventilation and air conditioning systems are increasing continuously. For the labor inspection and the AUVA, this was the reason to take a closer look at these problems.

These complaints are caused on the one hand by drafts, dry air or noises and smells. They can express themselves through diseases of the upper respiratory tract, headaches, sinus infections, nausea, susceptibility to infections, dry eyes, nervous or psychological disorders. In microbially contaminated ventilation systems, bacteria, fungi and their components pose additional risks for workers.

The labor inspection carried out a study on air conditioning systems together with the AUVA and analyzed the measurement results.
