Nuvap conducted a comparative IEQ analysis in 100 Italian offices belonging to 11 different vertical markets in the tertiary sector. The analysis considered 20 environmental quality parameters.
20% of the offices presented an insufficient Nuvap IEQ Index (in 5 cases it was lower than 4); only 19 companies reported an Index greater than 8 and the highest recorded value was 9.17.
A high variability of each parameter has been observed. The differences between periods of occupancy and periods of closure of offices (day / night and weekdays / weekends) were up to 80%.
Some pollutants have had a greater impact in compromising the value of the Nuvap Index: Gas Radon (26 offices), VOC (33 offices) and Formaldehyde are the parameters that have exceeded the alert values for more than 25% of the days of monitoring. Even the noise was too high in 11 offices.
It is not possible to define a pollution profile typical of a type of office, or a sector or a geographical area.
It is clear that indoor pollution is influenced by a mix of conditions that change on a case by case basis, mainly related to the human activities and the operations of the building systems.
Continuous monitoring enables improvement programs and innovation initiatives, offering:
‣ greater awareness about the highlighted problems;
‣ support for the implementation of best practices and behavioural solutions at zero cost;
‣ support for the communication of high indoor environmental quality conditions.
The project won the first prize of the “eHealth4ALL – Technologies for health and wellness” Award (edition 2017-19).
