1 A QUESTION INDOOR ENVIRONMENT QUALITY KEY TO HEALTH & COMFORT Avinash Kumar Where did you spend the maximum time in the last 24 hours? INDOOR! 2 WHAT IS SO IMPORTANT ABOUT IAQ? WHAT ELSE IS SO IMPORTANT ABOUT IEQ? Particle(s) per 35 cubic feet Clean air1 Outdoor air 1 Million Indoor air up to 100 Million According to TOI, 500,000 people in India die every year due to Indoor Air Pollution IAQ top 5 risks for public health (EPA & WHO) WHO estimates 30% of buildings are sources of illness (SBS & BRI) 50% of all illnesses by poor IAQ. (American College of Allergists) Legionnaire s disease spawned in air conditioning ducts. (ALA) Usage of PPEs for hazardous work The unawareness of potential hazards from IAQ is why it is even more important 3 4 DEFINITION : IAQ WHAT IS IEQ? Air inside a habitable structure Physical Characteristics Chemical Characteristics Airborne Constituents Occupant Health Comfort 5 6

2 7 DEFINITION : IEQ 8 Asthma, Bronchitis, Harms lungs Respiratory tract infection Heart diseases Allergies Fatal disease Other microbes too cause various diseases 9 10 Due to reduced supply of fresh air Contamination build up Chances of possible litigation increases! More contamination More fresh air More energy 11 12

3 13 STANDARDS AND REGULATIONS Sick Building Syndrome (SBS) where more than 30 percent of occupants experience adverse effects while in the building, but no clinically diagnosed disease is found. USEPA ASHRAE Building Related Illness (BRI) general term for a medically diagnosable illness caused by, or related to, building occupancy. ACGIH NIOSH OSHA 14 COMFORT TOTAL COMFORT- IEQ Absence of discomfort. The feeling of comfort or, more accurately, discomfort is based on a network of sense organs: the eyes, ears, nose, tactile sensors, heat sensors, and brain Thermal comfort Physiological Health Biological HVAC Systems Chemical IAQ HUMIDITY INDOORS HUMIDITY HEATH EFFECTS Indoor humidity is a function of Outdoor humidity Indoor sources: Unvented cooking, Unvented bathrooms Showering Number of Occupants Humidifier use Air conditioner use Clothes drying--mechanical or air drying DIRECT Eye irritation Respiratory mucociliary clearance asthma Dermal skin dryness Comfort perception INDIRECT Biological Dust mites (+) Molds (+) Cockroaches (+) Infectious agents Bacteria (+/-) Viruses [+ adenoviruses] Chemical Ozone (-) Formaldehyde, SO2, NO2 (+) 17 18
