Chemical Hazards
• Volatile Organic
Compounds
• Cleaning chemicals
and disinfectants
• Outdoor
contaminants
• Lab tests
Unique Ventilation
Requirements
• CDC and ASHRAE
Guidelines
• ASHRAE 62.1 –
Ventilation/recirculation/
mixing
• Challenge: introduce
moisture without
contaminating the air.
Effective Design Strategy: Children’s Hospital,
Fort Worth, Texas
Waiting Room: air
sweeps through
No mixing of air
HEPA Filtration
Savings from not totally
exhausting to the
outside
Infectious Isolation

IAQ Management Plan
Design Phase
Considerations
Construction Phase Issues
Operations and
Maintenance Procedures
IAQ Considerations in the Design Phase
• Site orientation and
preparation
• Room design: single
patient
• Pressurization:
Protective Isolation
v. Infectious Isolation
IAQ Considerations in the Design Phase
• Specify lowemitting materials
• Use of
antimicrobial
textiles
• Ventilation

Material Considerations in the Design
Phase --Furniture
Furniture Finishes- durable; inexpensive
Avoid sharp corners
Wipe-out drawers; seat backs
Easily moved or permanently affixed to floor
Able to withstand at least 300 pounds
Material Selection in
Design Phase
Correct Pressurization And Airflow Design To Minimize
Contaminant Spread Through Adjoining Spaces.

IAQ Issues during Construction Phase
• Precautions:
– Prevent Contaminant Spread—dust barriers
– Vigilance of HVAC- negative pressure
– Protection of building materials-moisture
– Commissioning of building systems
Maintaining proper IAQ during
Operations and Maintenance
• Biological pollutants: Mold and
bacteria
• Cleaning/maintenance of high
performance products/furnishings
• Cleaning products-source control
and low-VOC
• Cleaning time: traffic volume
A Study of Emissions:
Incubators
Environmental Testing Chambers used to study emissions from
neonatal unit for premature infants.
Results indicated emissions of formaldehyde, acetaldehyde and
methylmethacrylate as chemicals of concern.
Exposure concentrations elevate
risk for cancer and non-cancer
health effects

What have we learned so far?
• The healthcare industry will
benefit from sustainable building
practices.
• Issues such as aging populations,
need for healthy, friendlier
environments, and increased
legislation are driving new
construction.
• Effective design strategies include
minimizing biological, chemical
pollutants and optimal
ventilation.
• An IAQ Management Plan is
essential to optimizing healing
environments.
• Moisture control and specifying
non-toxic, low-emitting products
is essential to success of the plan.
• Numerous resources provide
guidance for proper design,
construction ,and operations and
maintenance of facilities.
This concludes the AIA portion of
the presentation.
We will now discuss GREENGUARD
Certification and provide resources
for your use.

Questions for Discussion
1. Name the standard which clearly
delineates IAQ ventilation rates.
2. Name three guidelines that available
when considering IAQ best practices
3. When considering healthcare design,
what are the three main considerations?
4. Are there other factors driving sustainable
building practices in Healthcare
environments?
