Death Rates caused by Air Pollution

App. 7 million premature deaths

- 600,000 of these children

Most common indoor air pollutants and what they release

COMBUSTION SOURCES

-candles

-tobacco products

-furnaces

-fireplaces

They Release

-carbon monoxide

-nitrogen dioxide

-small particles into the air

Causes of lung cancer in order

1. tobacco

2. Radon exposure

Symptoms caused by inhaling pollutants

headaches

dry throat

eye irritation

runny nose

WHICH MIGHT TURN INTO

Asthma attacks

cancer

Moisture infiltration

\___ into the interior of a building can cause structural damage, mold growth, and negative effects on indoor air quality.

Overall Air Aim

Ensure high levels of indoor air quality across a buildings life time through diverse strategies and human behavior interventions

Less severe symptoms of indoor air pollution exposure

headaches

dry throat

eye irritation

runny nose

More severe symptoms of indoor air pollution exposure

asthma attacks

infections with legionella bacteria

carbon monoxide poisoning

Annually in the US alone, indoor air pollution contributes to

thousands of cancer deaths

hundreds of thousands of respiratory issue

Breakdown of US spending in avoidable costs annually according to US EPA

100 billion NET

45% from Radon and Tobacco smoke

45% lost productivity

10% from avoidable

Most common indoor air contaminants

Combustion sources

-tobacco products

-stoves

-candles

-furnaces

-fireplaces

Combustion sources release pollutants such as

Carbon monoxide

nitrogen dioxide

small particles into the air

Besides combustion sources what else emits VOCs and SVOCs

Building materials

furnishings

fabrics

cleaning products

personal care products

air fresheners

A01 Air Quality Intent

provide a basic level of indoor air quality that contributes to the health and well being of building users

A01 Air Quality Summary

this well feature requires projects to provide acceptable air quality levels as determined by public health officials

A01 Air Quality Issue

exposure to air pollutants such as VOCs, Ozone, particulate matter, carbon monoxide have been shown to raise the risk of respiratory and cardiovascular diseases (as well as thousands of cancer death annually)

A01 Air quality solution

The W.H.O and U.S. EPA have a list of 'Criteria' Air pollutants

permissible levels for these criteria pollutants have been established based on epidemiological studies

permissible levels for these criteria pollutants have been established based on epidemiological studies that show

the relationship between concentrations

Duration of exposure

Health risks

Indoor air quality can be properly managed through the following WELL features:

Source control strategies

Passive and active building design

Operation studies

Human behavior interventions

What is effective at bringing radon levels below acceptable thresholds?

Effective mechanical ventilation

Modified thresholds in polluted regions

limited to WELL GOLD

Dynamic thresholds in polluted regions

limited to WELL SILVER

A02 Smoke free environment intent

deter smoking, minimize occupant exposure to secondhand smoke, reduce smoke pollution

A02 Smoke free environment summary

this WELL feature requires projects to ban indoor smoking and ban or restrict outdoor smoking w/ in its boundaries

A02 smoke free environment issue

Exposure to tobacco smoke detrimentally affects the health of smokers and those exposed to secondhand smoke

-of the 700,000 compounds cigarettes release at least 69 are carcinogenic.

Bc of this the average life expectancy of a smoker is 10 years shorter

-secondhand smoke exposes more people to these contaminants which increases the number of people with health risks

Thirdhand smoke

residual chemicals left on indoor surfaces where smoking has occurred

Thirdhand smoke clings to

Walls, furniture, clothing, bedding, carpets, and surfaces long after smoking has occurred.

Health issues associated with tobacco smoke:

Asthma attacks

Respiratory infections

Coronary heart disease

Stroke

Lung cancer

Sudden infant death syndrome

despite these terrible effects

80% of the global population lives in countries not protected by 100% smoke free regulations

Where is smoking banned

Outdoors @ ground level w/in 25 ft (or allowable extent by local codes) of all entrances, openable windows, and building air intakes.

anywhere interior

On decks, patios, rooftops, and other occupiable outdoor areas above ground level

signage rules for smoking ban

-Signage is present to clearly communicate the ban.

-in indoor areas w/in the project boundary that allows smoking, signs are placed along walkways (not more than 100 ft between signs) that describes the hazards of smoking

A03 Ventilation Design Intent

Minimize indoor air quality issue through the provision of adequate ventilation

A03 Ventilation Design Summary

Projects to bring in fresh air from the outside through mechanical and or natural means in order to dilute human and product generated air pollutants

A03 Ventilation Design Issue

Poorly ventilated spaces contribute to:
