Why is Indoor Air Quality Important?
• People spend more than 90% of their time indoors
• People receive the majority of their environmental exposure to chemicals indoors (70%+)
• Air pollutions levels indoors are typically 2x5 (sometimes 1,000x) higher than those found outside

13
IAQ and Health
• Asthma and allergies • Headaches• Respiratory disease• Eye, nose & throat irritation• Reproductive / developmental
defects• Neurological disease• Cardiovascular disease• Some forms of cancer
Copyright © 2014 Underwriters Laboratories. All rights reserved.
14
• 14% of annual healthcare cost from IAQ related health effects
• 14.7% increase in math and 13.7% in reading scores through better IAQ
Good IAQ is Good Policy
Copyright © 2014 Underwriters Laboratories. All rights reserved.
15
• 8-10% increased productivity through improved IAQ
• Average salaries ~ $2,000/m2
• $160/m2 vs. $3/m2
• Offset energy savings 50x
Good IAQ is Good Business
Copyright © 2014 Underwriters Laboratories. All rights reserved.
16
• Remediation costs on average over 100 times more than prevention
• Estimated 8-10% of buildings with mold and moisture problems in UAE
Good IAQ is Good Business

Mold
• Mold spores are found everywhere, indoors and outdoors
• Mold GROWTH should not occur indoors
• Key question:
NOT if mold is present?
but…
Is there sustained GROWTH?

23
Building Reality
• Aggressive budgets and schedules
• Unproven materials • Unique building features • Little to no IAQ
commissioning
Copyright © 2014 Underwriters Laboratories. All rights reserved.
24
• Shift from natural to mostly synthetic materials
• Compacted work spaces
• Decreased ventilation
• Tighter Envelopes• Designs can lack necessary
contextual response

Green Building Systems
• Limited focus on IAQ• Insufficient Requirements• Healthy IAQ not a “must have“• Potentially compromising
incentives

Trend towards requiring less ventilation:1. Energy conservation
2. Cost savings
