Air pollution, and health data

Latest findings


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

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 values


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€

Clean Air For Europe CAFE project data


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


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

The biggest cost for a company is salaries

© CAMFIL FARR 2023-04-13

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

Donald K. Milton, P. Mark Glencross, And Michael D. Walters Risk of Sick Leave Associated with Outdoor Air Supply Rate, Humidification, and Occupant Complaints – Indoor Air 2000 10: 212-22

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

http://www.inive.org/


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%
