2. Building indoor environment covers the
environmental aspects in the design,
analysis, and operation of energy-efficient,
healthy, and comfortable buildings. Fields
of specialization include
thermal indoor air
architecture, HVAC design,
comfort, quality (IAQ),
control
lighting, acoustics,
systems
Indoor environment

4. Environmental
Symptoms
Condition(s)
• Ergonomic Conditions • Headache
• Noise and Vibration • Fatigue
• Poor Concentration
• Dizziness
• Tiredness
• Headache with nausea
• Ringing in ears
• Pounding heart
• Relative Humidity • Dry throat
• Shortness of breath or bronchial asthma
• Irritation and infection of respiratory tract
• Relative Humidity • Nasal problems (stuffiness, irritation)
• High Temperatures
• Warm Air • Skin problems (dryness, irritation, rashes)
• Low Relative Humidity
• Excessive Air

spend at least
half of their
lives indoors.

9. Indoor air pollution is the
presence of one or more
contaminants indoors that carry
a certain degree of human
health risk. Indoor air issues
may be traced to the beginning
of civilization. Prehistoric
records note the problem of
smoke in caves.
Field studies of human
exposure to air pollutants
indicate that indoor air levels of
many pollutants may be two to
five times, and on occasion
more than one hundred times,
higher than outdoor levels.

12. Condition associated with
complaints of discomfort
including headache;
nausea; dizziness;
dermatitis; eye, nose,
throat, and respiratory
irritation; coughing;
difficulty concentrating;
sensitivity to odors;
muscle pain; and fatigue.

20. insufficient fresh
outdoor air entering
a ventilation system
are often the direct
result of overzealous
energy-saving
procedures.

24. Acoustics is the interdisciplinary science
that deals with the study of all mechanical
waves in gases, liquids, and solids
including vibration, sound, ultrasound and
infrasound. A scientist who works in the
field of acoustics is an acoustician while
someone working in the field of acoustics
technology may be called an acoustical
engineer. The application of acoustics can
be seen in almost all aspects of modern
society with the most obvious being the
audio and noise control industries.
Acoustics

25. How to Control/ Eliminate
Indoor Air Pollutants
Don’t Smoke inside Pay attention to Check combustion
the home. housekeeping. appliances.
Control/ eliminate
excess
Test your home for moisture
Radon
•Improve home
ventilation

26. Have furnace, Never run
flues, your car
chimney inside an
inspected and attached
cleaned garage
Never use Install a
unvented carbon
space monoxide
heaters/ gas detector
logs in your home

27. Control Moisture In and Around the Home
Repair leaks and drips
Check to be sure clothes dryer vented to
outside
Move water from gutters and
downspouts away from house
Use ventilating fan in kitchen and
bathroom
No water in crawl space

28. Moulds
are fungi that grow in the form of multicellular filaments called hyphae.

29. HIGH INFLAMMATORY
MEDIATORS
FOUND IN NASAL FLUIDS OF
PERSONS IN DAMP BUILDINGS
MITES, BACTERIA, MOLDS,
ENDOTOXINS ALL CONTRIBUTE
MINIMIZED BY HUMIDITY &
MOISTURE CONTROL IN BUILDINGS

30. Radon

31. In 1990 EPA placed indoor air pollution at the top
of the list of 18 sources of cancer risk
Indoor pollution is rated by risk analysis
scientists as high-risk health problem for humans
Radon is one of the three most dangerous indoor
air pollutants, along with cigarette smoke and
formaldehyde
Radon is the second leading cause of lung cancer,
after smoking
Nearly 1 in 15 homes in the U.S. has high level
of indoor radon
Homes with high radon level can be fixed
INDOOR AIR POLLUTION: RADON

32. A. Cracks in concrete slabs
B. Spaces behind brick walls
C. Pores and cracks in
concrete blocks
D. Floor wall joints
E. Exposed soil as in a sump
F. Weeping tile, if drained to
open sump
G. Mortar joints
H. Loose fitting pipe
penetrations
I. Open tops of block walls
J. Building materials such as
some rocks
K. Water, from some wells
INDOOR AIR POLLUTION: RADON

33. Radon Resistant-
Construction Techniques
A. Gas Permeable Layer
B. Plastic Sheeting
C. Sealing and Caulking
D. Vent Pipe
E. Junction Box
Other radon reduction
techniques include
sealing, home/room
pressurization, heat
recovery ventilation and
natural ventilation.
