CONCLUSIONS OF THE RESULTS PRESENTATION DAY

On April 20, we celebrated the Final results dissemination evento of the 3SQAIR Project with the participation and contribution of all the project partners.

Two days of intense work in which we presented the results of the pilot projects, the experiences carried out in the centers as well as the doubts and challenges that the project has generated.

Here we leave you the conclusions of the sessions, which can serve as conclusions for the entire project:

CONCLUSIONS

  • Indoor air quality monitoring provides information about the trend of different monitored parameters and is an excellent diagnostic tool. It allows for understanding the evolution of different parameters, as well as the response of existing building improvement systems (if any), such as ventilation and/or air purification systems.
  • In this case, indoor temperature, relative humidity, CO2, total volatile organic compounds, formaldehyde, and suspended particles of up to 1, 2.5, 4, and 10 microns in size were monitored. The evolution during a workday is not decisive in identifying the pattern of space use, as it is a one-time event. However, it allows for identifying rest periods due to door opening and therefore more effective cross ventilation, and low chemical contaminant levels throughout the monitored period – between 8:30 am and 6:00 pm.
  • Low-cost technology with lower accuracy but high scalability, such as that used in space monitoring or during the project, allows for covering a larger number of spaces and integrating knowledge about indoor air quality in the form of recommendations, business intelligence, and control algorithms.
  • It is as important to measure as it is to convert data into useful information for analysis and interpretation by both technical and non-specialized profiles. This information can help evaluate and mitigate the impact on health from different monitored parameters. Technology is a key tool that feeds on generated knowledge to offer information tailored to each project’s needs. Continuous evaluation over time allows for studying not only punctual exposures to high doses of contaminants but also the prolonged effect of continuous exposure to low doses of contaminants, identifying the % of occupancy time that has exceeded safe levels for each monitored parameter.
  • Harmonizing the type of indicator used to evaluate indoor air quality is essential when so much data is available. In this 3SqAIR project, the most critical weeks of both heat and cold were studied, and available tools need to facilitate the calculation of hourly, daily, and/or cumulative values, adjustable to different data analysis criteria.
  • Indoor air quality monitoring solutions must be flexible and scalable, adapted to all types of buildings and users. Understanding the evolution of CO2 as an indicator of ventilation system effectiveness is critical, but additional steps must be taken to integrate other parameters and available technology and knowledge to delve into how indoor air quality affects health according to each type of space.
  • Next steps: controlled mechanical ventilation on deman Low-cost technology with lower accuracy but high scalability, such as that used in space monitoring or during the project, allows for covering a larger number of spaces and integrating knowledge about indoor air quality in the form of recommendations, business intelligence, and control algorithms.
