4. Indoor Air Quality - What’s Changed?
ASHRAE Position Paper, June, 2009
• Acknowledges that HVAC systems
play a role in the dissemination of
diseases in buildings
• Key points:
– Infectious diseases can be
transmitted via an airborne path
– Designers have a responsibility
to minimize that potential
 Dilution ventilation
 Building pressure control
 Filtration
 Oxidative technologies,
 UVGI, PCO

5. Public Awareness of Air Cleaning – What’s
Changed?
• 3M has been a forerunner with ads depicting their
Filtrete® brand capturing more airborne particles
and organisms than lower rated filters. Filtrete®
dominates the retail high-end filter market.
• The H1N1 influenza pandemic showed how easily
the virus can be transmitted among humans.
Pictures of millions wearing face masks have
solidified the perception that germs are airborne
and filtration can help prevent infection.
“In our study, we revealed, to our knowledge for the
first time, the presence of airborne influenza virus
particles in a health care environment”.
CDC NIOSH, Feb. 2009
Airborne Disease: Now a Forethought

11. II. Ultraviolet Germicidal Irradiation (UVGI)
Microbiological Inactivation
Most
• C-band ultraviolet; 254 nm susceptible
virus
• Effectiveness is dose-related
(intensity x time)
vegetative bacteria
• “Killing” dosage varies widely
by species of microbe mycobacteria
• Designed for specific duty
bacterial spores
o Surfaces: low intensity, effective
o On-the-fly “kill:” difficult to achieve fungal spores
Least
susceptible

12. Vapor Phase (Gaseous) Air Cleaning
• What type of gases are floating around?
– Irritants ( Aldehydes, Ozone, CO, Methane)
– Odorous (cleansers, cooking)
– Corrosives (SO2, Chlorine)
• What are common indoor sources?
– Paints and solvents
– Combustion sources
– Sewer Gas
– Plastics, furniture and carpets
– Printers and copiers
– Aerosol sprays
– Cleaning products and disinfectants
– Pesticides and bug repellents
– Air fresheners
– Mold (Toxins)
– Adhesives, caulk
– People
– Cooking Odors

14. III. Photo-Catalytic Oxidation (PCO)
• Catalytic Conversion
– Newest technology in
commercial HVAC market
– Analogous to car catalytic converters
– Conversion process: changes molecular structure of
contaminant to less toxic substances
– Needs an energy source and a catalyst to force chemical
reactions in airstream
– Works on organic compounds by breaking the carbon
chains
14 Trane Catalytic Air Cleaner

15. III. Photo-Catalytic Oxidation (PCO)
• UV light creates photons,
a form of light energy
• Photons are “catalyzed” by
the TiO2 forming hydroxyl
radicals
• Radicals last less than 1/10
of a second and react with
carbon-based compounds
• Organic compounds can be
reduced to CO2 and H2O

to reimburse for medical
expenses due to HAI’s.
• Lawsuits against hospitals
causing infection are up 50%
in the last 10 years.
Hospitals today face increased financial exposure

22. Air Cleaning Needs in Schools
• The EPA has citied that poor indoor air quality can impact the comfort and health of
students and staff, which, in turn, can affect concentration, attendance, and student
performance.
• In 1999, Indoor air quality (IAQ) was reported to be unsatisfactory in about one in five
public schools in the United States, while ventilation was reported as unsatisfactory in
about one-quarter of public schools
-National Center for Education Statistics of the Department of Education
• Growing concerns with
– Crowded classrooms
– Hygiene issues
– Absentee rate
– Teacher attendance
– Improved protection against outbreaks
Schools today have added concerns for child safety
