Indoor air quality and comfort level

The carbon dioxide concentration and the indoor air quality in interiors are deemed to be the most important indicators that the quality of the indoor air is good enough.

• Evaluate indoor air quality by CO₂ and other measurements
• The CO₂ concentrations should not exceed 1,000 ppm

Air velocity in indoor areas directly affects thermal comfort.

• The turbulence indicates the air velocity fluctuation and intensity of air flow
• Exact measurement of air temperature and turbulence

The parameters air temperature and relative humidity are important when planning, choosing and setting heating and ventilation systems.

• Recommendations for the relative air humidity: 30 % to 65 %

Extreme conditions in workplaces often specifically lead to more arduous work loads.

• The WBGT index (Wet Bulb Globe Temperature) is used to evaluate workplaces which are affected by thermal radiation
• Compliance with DIN 33403 and ISO 7243

A person's sense of well-being in a room (level of comfort) depends on a series of particular external influencing factors.

• All of the parameters combined in the PMV/PPD measurement
• Average climate assessment value
• According to ISO 7730

Suitable lighting in the workplace provides workers with sufficient light to be able to perform their jobs well.

• Measure and assess luminous intensity (natural or artificial light)
