Indoor Climate

The employer is obliged to guarantee suitable indoor climate and fresh air supply at workplaces. When determining the suitable indoor climate, the employer must consider the size of the room, number of employees, the mental and physical workload of employees and the specifics’ of the used tools and technology.

Previously it was thought that it is enough to limit and measure air temperature, relative humidity and air movement speed to characterize the indoor climate of a workplace. Today, the suitability of the workplace climate is determined on a different basis, presented in the unified standard EVS-EN 15251 – „ Indoor environmental input parameters for design and assessment of energy performance of buildings addressing indoor air quality, thermal environment, lighting and acoustics”.

To determine the thermal comfort of the working environment, the following parameters are taken into account:

  • air temperature,
  • temperature of radiation emanating from the Sun or heating devices,
  • temperature of radiation beaming from walls, windows, floors or ceiling,
  • relative air humidity,
  • air movement speed,
  • the employee’s physical activity,
  • heat-proofness of clothes, incl. protective clothes,
  • work organization aspects, such as the possibility of having a break, etc.

Bad indoor climate creates a sense of discomfort while being present in the working premises, has a negative influence on the working capability and may cause health problems. Symptoms decrease and gradually disappear after leaving the room or building.

Signs of a poor internal climate include:

  • irritation of eyes, nose or throat mucous membrane;
  • skin irritation;
  • headache or a sense of heaviness in the head;
  • unnatural fatigue or concentration problems, nausea and dizziness.

Poor indoor climate could influence the course of many illnesses but mostly affects the respiratory infections and conditions like asthma, bronchitis and sinusitis.
