This document discusses indoor environmental quality and ways to improve air quality. It covers topics like tobacco smoke control, improving air quality through minimizing clutter and regular cleaning, using natural daylighting strategies, ensuring adequate fresh air ventilation through open windows and doors or mechanical systems, installing exhaust systems in kitchens and bathrooms, using low VOC materials and conducting building flush-outs before occupancy. Improving indoor air quality is important for health as poor air quality can cause diseases like cancer and respiratory illnesses.

1. Indoor Environmental
Quality (IEQ)
“Green is a process, not a status. We need to think of
'green' as a verb, not an adjective.”

3. According to WHO ,
30% of all cancer deaths
20% of all coronary heart diseases
80% of all chronic obstructive pulmonary disease
Are caused by cigarette smoking and tobacco.
When you smoke a cigarette
most of the smoke doesn't go into your lungs,
it goes into the air around you,
where anyone nearby can breathe it in.
When friends and family breathe in your secondhand
smoke –
what we call passive smoking –
it isn't just unpleasant for them, it can damage their health
too.
Environmental Tobacco Smoke Control

4. Odors and toxins from
cigarettes can be found for
months after smokers move out
of a residence. Surprisingly,
plants may be your best option
for cleaning that unhealthy air.

6. HOW CAN WE IMPROVE THE AIR
QUALITY AT PERSONAL LEVEL?
MINIMIZE CLUTTER
VACUUM CLEANING

7. REMOVE CARPETING AVOIDING AIR

8. DAY LIGHT
Natural daylight.
An effective day lighting strategy.
Optimization of spaces.
 Use glass walls and light-colored surfaces on walls
 Window area to (window) wall area ratio-IS related to limiting glazing area for
thermal reasons, ie. heat loss and gain control, or for ensuring the adequate
provision of view.

9. NATURAL LIGHTING BENEFITS
•Reduced energy consumption.
•Reduction of mildew or mold built-up.
•Healthy does of vitamin D.
•Improved performance due to change in working environment.
•Increased visual appeal in interiors.

11. The process of "changing" or replacing air in any space to provide high indoor air quality
.
WHY IT IS NEEDED?
• CONTROLS IMPURITIES
• AIR CIRCULATION
• STOPS CONDENSATION
• REDUCES TEMPERATURE
• HEALTH BENEFITS

12. Design Criteria for Openable Windows and Doors to the Exteriors
Percentage of Openable area to Carpet area
Space Type
 Living Spaces - 13%
 Kitchen - 10%
 Bathrooms* - 5%
 For air-conditioned spaces, to meet 6.5 cfm per person.
Natural Ventilation Mechanical Ventilation

13. Cross Ventilation

14.  Ensure that kitchens and bathrooms are adequately ventilated, so as to improve
the quality of indoor environment.
 Minimum Intermittent Exhaust Flow Requirements
 Location Floor Area Minimum Airflow
 Kitchen ≤ 9.30 sq.m (100 sq.ft) 100 cfm
 Bathroom ≤ 4.64 sq.m (50 sq.ft) 50 cfm
Exhaust Systems

15. Low VOC Materials, Paints & Adhesives
Why VOC ?
• To reduce adverse health impacts on building residents.
• To reduce chemical emissions from VOC's
• Improve air quality
• To nuisance odour complaints – eye and respiratory irritations, headache, and
other symptoms of "Sick Building" syndrome.

16. Building Flush-out
• Avoid resident’s exposure to indoor airborne contaminants before occupying
the premises, so as to reduce the adverse health impacts on building
residents.
Compliance Options:
• Perform a building flush-out for ten days by keeping all windows open
before the building is occupied. Flushing is to be carried after paints &
coatings and adhesives & sealants have been applied. (OR)
• If the building prefers to carry out the flush-out using forced ventilation
systems, the flush-out can be carried out for five days.
