This document discusses green building and indoor air quality. It notes that buildings account for a large percentage of energy, water and carbon emissions in the US. Building green provides healthier homes that cost less to operate. It also summarizes factors that affect indoor air quality like sources of pollution from building materials and HVAC systems. Finally, it discusses strategies for improving indoor air quality through design, maintenance and administrative controls.

3. When you build green,
1. You take affordable housing to the next level of
performance.
2. You give owners and residents more comfortable
homes that cost less to operate, last longer, and
keep occupants healthy.
3. You keep current with leading building techniques
and gain valuable experience with a team
approach that improves design and construction.
4. And of course, you help improve our environment
as your buildings become more efficient, use less
resources, and reduce their impact.

15. Indoor Air Quality in Homes
Indoor Air Pollutants May Be 100 Times Higher Than
Outdoor.
People Spend As Much As 90% of Their Time Indoors.
Short and Long Term Health Effects Can Result From
Poor Indoor Air Quality.
Training Is Essential to Maintaining IAQ And Safety.

16. IAQ Problem Indicators
Symptoms Are Widespread Within A Certain Area.
Symptoms Disappear When Homeowners Leave
The Home.
Symptom Onset Is Sudden After Some Change At
The Home.
- Such As: Painting Or Pesticide Application, Storm.
Persons With Allergies, Asthma, Or Chemical
Sensitivities Have Reactions Indoors But Not
Outdoors.
A Doctor Has Diagnosed An Occupant As Having
An Indoor Air-Related Illness.

17. IAQ Health Effects
Symptoms of Certain Diseases, Including
Asthma, Hypersensitivity Pneumonitis, and
Humidifier Fever, Can Appear Soon After
Exposure to Some Indoor Air Pollutants.
When Symptoms of Diagnosable Illness Can Be
Attributed Directly to Airborne Building
Contaminants, They Are Referred to As Building-
Related Illness.

18. IAQ Health Effects
In Contrast, There Are Situations In Which
Building Occupants Experience Symptoms That
Do Not Fit The Pattern Of Any Particular Illness.
This Phenomenon, Referred To By Some As Sick
Building Syndrome, Is Often Temporary.
Some Buildings Have Long Term Problems.
Frequently, Problems Result When A Building Is
Operated Or Maintained In A Manner That Is
Inconsistent With Its Original Design Or
Prescribed Operating Procedures.
Air Handling Equipment That Is Improperly
Maintained Or Operated Can Sometimes Be The
Problem.
