1. Indoor Air Quality Police-project: a new practice to assess indoor air quality

2. About project
Indoor Air Quality Police-project (funded by Tekes, grant number 4098/31/2015) is a national study that aims:
to develop an internet-based online system that extend both collected indoor air quality data from the buildings and feedback of the users
The project consist of five
work packets that
are closely
combine together
I Devices and sensors
V Fieldwork
II Internet of the items and data collection
Workpackets
IV Modelling of the conditions and analyzing of the data
III Feedback of the users and feedback collection

3. Field measurements I Conducted in six secondary schools:
- 4 with IAQ problems
- 2 reference schools
six classrooms from each schools
 36 all together
Questionnaire:
6th- 9th grade pupils and their teachers
Two weeks period, at the end of the lessons
Also paper questionnaires available
Timetable:
Autumn 2016
three schools
Spring 2017
 three schools

4. Field measurements II
Two weeks:
- humidity, temperature, carbon dioxide, TVOC, dustiness, noise and lightness ( classrooms)
- humidity, temperature, carbon dioxide, carbon monoxide, TVOC, ozone, arsine, ammonia, hydrogen sulfide, formaldehyde and particles (one classroom)
Other:
- Settle dust sample from surfaces
- Vacuumed dust samples for endotoxin analysis
- 8 liters active air sample
- Air samples for characterizing microbes and bacters
- Outdoor T, RH, particles and other parameters
- Pressure difference between indoor and outdoor
- Amount of income and outcome from all of the ventilation endpoints

5. Symptoms and perceived indoor air quality questionnaires for teachers and pupils

6. Questions only first time:
School
Age
Gender
Health status
Respiratory illnesses
Allergic diseases
Moisture damage of the home, pets, housing, number of the persons in family, smoking
Student / teacher  class / classrooom number

7. IAQ factors

8. Symptoms…

9. …Symptoms

10. What new…?
We have an opportunity to assess an information about possible indoor air related symptoms and discomfort simultaneously with real-time measured exposure factors…
…Information has been collected from the same indoor air space and from the same people for several times…
…There is potential to notice and determine new markers that are in key roles and have adverse effect on indoor air quality and on human
…Indoor Air Quality Police-project will establish a new practice to assess the associations between measured and perceived indoor air quality.

11. Now it’s your turn to answer
You will get the link to the questionnaire by
Hopefully everybody here answer as soon as get the link
You can choose are you ”answering firts time” or ”have you answered before”
All your answers are deal with confidence and group-level
