Indoor Air Quality Police-project:
a new practice to assess indoor air
quality
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
Workpackets
IV Modelling of the
conditions and
analyzing of the
data
II Internet of
the items and
data collection
III Feedback of the
users and feedback
collection
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
Field measurements II
•
Two weeks:
- humidity, temperature, carbon dioxide, TVOC, dustiness, noise and lightness (6
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
Symptoms and perceived indoor air quality
questionnaires for teachers and pupils

IAQ factors
Symptoms…
…Symptoms
What new…?
We have an opportunity
to assess an information
about possible indoor air
related symptoms and
discomfort
simultaneously with realtime measured exposure
factors…
…Information has been
collected from the same
indoor air space and
from the same people
for several times…
…Indoor Air Quality Police-project will establish a
new practice to assess the associations between
measured and perceived indoor air quality.
…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
Now it’s your turn to answer
