Latest findings

4. Air pollution has a confirmed health impact
which will reduce performance
1. Proximity to roads increases air
pollution health effects
2. Even low concentrations of
PM2,5 impacts health
3. WHO classified Diesel engine
exhaust as carcinogenic

5. Busy roads causes 15 to 30% additional asthma
and respiratory diseases in large cities
Nitrogen dioxide levels in Paris 2011, PM10 and PM2,5 follow same pattern, above their limit

Air pollution in Europe: a silent killer
• 80% Europeans live in areas exceeding air pollution limits
• 450 000 premature deaths in Europe
• 9 months life expectancy lost on average
• 0,5 days sick leave per working European costing 80 b€

7. Most discussions are about outside air but
indoor air quality is often worse….
• We spend 90% our time indoors
• Indoor air can be 2 to 5 times more polluted
than outdoors
• 50% of all illnesses are caused or
aggravated by poor IAQ*
• 2 millions healthy life years are lost every
year in Europe due to poor IAQ**,
• Poor IAQ costs to Europe 110 billion€
health care costs**
• Combustion particles cause 50% of poor
IAQ related diseases**

8. Beyond the public health
impact, how businesses
will benefit from better
indoor air quality?

Office building total cost
Employees salaries 84%
Rental costs 13,6%
Maintenance, repairs 1,25%
Utilities resources 1,17%

The biggest cost for a company is salaries

10. Better IAQ improves productivity, protects
health and directly impacts the bottom line
Increasing staff by 1% is a cost increase of the same magnitude as doubling the
utility costs. What if you could increase productivity of existing staff by 1%
instead…

11. Good IAQ can reduce sick leave rates and
save a lot of money
Polaroid managed to reduce
sick leave by 35% by
upgrading the HVAC system.
The result was $400 net
saving per year per employee
Total annual savings = 1 488 000$

Good IAQ can increase productivity in office
building
A study at a call centre
showed a 10% increase in
operators productivity by
replacing old filters with new
at a higher outdoor air supply
rate

13. Up to 4000 office workers everyday in the
Gherkin in London
How much potential savings if we can
• Improve workers’ productivity by 10%
• reduce by 35% sick leave rates?
• Or save $400 net per year per worker ?

14. Good IAQ improves schoolchildren performance
In US a study has show that
performance in both math and
reading tests
increased 13% with higher
ventilation rate
A Norwegian study showed
that reaction times were 5.4%
faster with a ventilation rate
12 l/s per person, compared
to 4 l/s per person

15. Remember, old and dirty filters easily can
deteriorate IAQ
Keeping the dirty filters and an
increasing ventilation rate from
2,5 to 25 l/pers/s reduced
productivity in an office building
by 8%
With new filters performance
increased by 6%
