Sick Building Syndrome
Indoor Air Quality - IAQ
3
Indoor Air Quality Concern
Indoor Air Quality (IAQ) is an important determinant of individual’s
performance, health and well being.
This is because people spend most of their time in indoor then out door
Results of numerous studies have demonstrated that Building Related Symptoms (BRS) can adversely affect
efficiency, productivity and occupant well being.
4
Studies on IAQ
Indoor Environment contains variety of visible & invisible contaminants
Airborne diseases are 2 to10 times higher in indoor then outdoor
Fresh Air is restricted in closed environment of doubled glass buildings
Lack of fresh air intake increased use of artificial synthetic building materials
5
Indoor Air Contaminations
VOC ODOR SMOKE DUST CO2 FUNGUS, MOLD AND MICROBES AIR BORNE BACTERIA
6
VOC CONSTITUENTS
There are more than 100 known VOCs
Most VOC are Hydro Carbon Contain Carbon, Hydrogen & Oxygen
Susceptible to Oxidization Oxidization Reduces these to
O2, H2O, & CO2
7
SOURCE OF VOC Body Excretions Furniture Paints, Varnish & Polish Sticking chemicals Carpets Stationary, Printers & Copiers Cooking Aerosols & Cleaning Chemicals Pest control chemical
8
ODOR
ODOR IS MAJOR IRRITANT
TRANSIENT ODOR (Instantaneous) RESIDUAL ODOR (Retained Odor)
Residual odor - Difficult to Remove by Conventional Methods
9
SOURCE OF ODOR
Food odorBody odorCigarette SmokeOdor from footwearCarpetFurniture GlueSynthetic MaterialPaint, varnish, polishCleaning Chemicals
Burnt rubber, plastic, wood, wire
Dead rodent, bird, insectsSTPOdor & Toxicity from

CO2
CO2 IS NOTVOC Toxic Carcinogenic Odorous
High level of CO2 can CauseHeadaches | Restlessness | Reduced Concentration |
Tiredness Fatigue| Lethargy | Reduced Tolerance | Irritability | Difficulty in Breathing | Sweating |
Increased Heart Rate | Elevated Blood Pressure
12
SOURCE OF CO2
In an indoor environment human being exhale CO2
Carbon Dioxide cannot be filtered, adsorbed, reduced or oxidized.
Carbon Dioxide has to be neutralized with oxygen
13
These are collectively known as
“ SICK BUILDING SYNDROMES ”
14
• Headache, Reduced Concentration• Reduced Tolerance, Irritability, Restlessness• Eye Irritation, Eye watering • Asthma, Nose & Throat Irritation, Cold & Cough• Increased Heart Rate, Elevated Blood Pressure• Verity of Allergies, General Fatigue, Sweating,
Lethargy
Sick Building Syndromes are
15
Reduce VOCReduce / Remove Odor
Reduce / Eliminate Fungus, MoldReduce / Eliminate Airborne Bacteria & Viruses
Lower / Maintain Carbon Dioxide levels
TO ADDRESS “SBS”
16
To reduce Sick Building Syndrome (SBS) &
Enhance Indoor Air Quality (IAQ)
Outdoor Fresh air is taken by AHU System
CONVENTIONAL SOLUTION
17
Oxidation VOC & Odor Lower /Maintain CO₂
up to desired level
ROLE OF OUTDOOR FRESH AIR
Oxidation75%
CO₂25%
Role of Fresh Air
Oxygen in fresh air is Oxidizing agent; 75% of Oxygen in fresh air is consumed for Oxidation
25% of Oxygen in fresh air is consumed to neutralize CO₂
18
Structure of fungi, mold, airborne bacteria & virusesFungi is Hydro Carbon mass with hard protein shell. Its outer Shell is a porous membrane. O2 in fresh air reaches inner hydro carbon mass by the process of osmosis. With this cell metabolism splits it to 2 or more cells. This sets in
the process of fungi multiplication

Controlled Injection Of “ Medical grade Ozone ”
in AHU System
Chemtronics SOLUTION
21
VOC & Odor :
Ozone is more powerful oxidizing agent then Oxygen; Thus VOCs , Odor & pollutants are
efficiently oxidized
& 60 – 70 % of oxygen in fresh air is
conserved.
Advantages of Ozone Injection
Fungi & Mold :
Ozone (Even in low concentration), interferes with the process of cell metabolism. This Retards the Process of Fungi & mold multiplication. Over the
period of time, Fungi & microbes Colony Depletes
Reaching Near Total Elimination
22
Advantages of Ozone Injection
23
Airborne Bacteria & Viruses :
Ozone kills (Oxidizes) bacteria & Viruses almost instantly. Also fungi in ducts & coil Provide Food & Nutrients for Air
Borne Bacteria to Grow & Propagate; Ducts, Coil, AHU are Breeding Grounds for Bacteria, When Mold & Fungi Are
Eliminated, Food & Nutrients to Air Borne Bacteria & viruses is Deprived
Results in Dramatic Reduction in Air Borne Bacteria
Advantages of Ozone Injection
24
Dust (SPM) :
For Any Object (dust / suspended particulate matter) to Adhere, Force of Adhesion is Necessary. In AC Duct, Air Travels at Velocity of 1200 to 1500 FPM (365 to 450 M/Min). There Should be Compelling Reason for Dust to Depart this high Velocity Stream and Adhere to Duct Surface. This is Due To Bio Adhesive Force Provided by Fungi
Results in Reduction in Suspended Particulate matters
Advantages of Ozone Injection
25
Carbon Dioxide :
When 60 – 70 % of oxygen in fresh air is conserved using ozone injection in AHU. More oxygen is now
available to neutralize carbon dioxide.
This lowers CO₂ levels very significantly.
Advantages of Ozone Injection
26
These multiple effects of Ozone brings “ Freshness in the closed
environment ”
Completely Eliminates“ SICK BUILDING SYNDROME ”
& Greatly Enhances “ Indoor Air Quality ”
