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

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€

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**Construire sainGuide à l’usage des maîtres d’ouvrage et maîtres d’oeuvre pour la construction et la rénovation - Novembre 2011• American College of Allergy, Asthma & Immunology ** Envie Report, DG S ANCO

Excluding taxesAdapted from Rehva guidebook n° 6 Indoor Climate and productivity in offices
Office building total cost
Employees salaries 84%
Rental costs 13,6%
Maintenance, repairs 1,25%
Utilities resources 1,17%

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…

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
Wargocki, Improving Indoor air Quality improves the performance of office work and schoolwork, INIVE International Network for Information on Ventilation and Energy Performance www.inive.org
Clean air solutionsClean air solutionsClean air solutionsClean air solutionsClean air solutions
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 ?

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 personReferences (1) Shaughnessy, R.J., et al., A preliminary study on the association between ventilation rates in classrooms and student performance. Indoor Air, 2006. 16(5): p. 465-468. (2) Myhrvold, A. and E. Olesen, Pupil’s health and performance due to renovation of schools, in Healthy Buildings/IAQ 1997. 1997. p. 81-86

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%
