Its concentration depends on the number, demographics, and activities of occupants, the outdoor air supply rate, mixing, inter-zonal airflow, the air renewal rate, and the outdoor concentration.

 

IAQ in working environments in Belgium: alternative approaches to CO2 requirement

In March 2016 a new regulation came into force in Belgium regarding the wellbeing at work, with specific requirements on the indoor air quality (IAQ). The requirement is expressed as a maximum absolute CO2 concentration of 800 ppm in all working spaces. Compared to the previous requirement, i.e.

THE INFLUENCE OF ROOM TEMPERATURE AND RELATIVE HUMIDITY ON ODOR IN A UNIT-TYPE NURSING HOME

The investigation was conducted to investigate the relationship between thermal conditions andindoor air quality during summer in a new unit-type nursing home. Almost all occupants in the nursinghome spend the daytime in the nursing homes common space area. We set out to examine how theindoor environment changes and what influence the thermal environment has on odor, and thereforetook readings in the common space for room temperature, relative humidity, CO2 concentration andodor levels.
