CO2 Levels Monitoring – INDOORS VERSUS OUTDOORS

THE BUILDING

- India’s FIRST USGBC LEED Platinum Building for Existing Buildings

- BEE 5 Star Rated Building certified with an AAhEPI of 28 Whr/hr/m2

- Indoor Air Quality equivalent to being up in the mountains

- DAVOS in DELHI (The world’s most polluted city)

What is in the air we breathe?

& how it affects us…

VOLATILE ORGANIC COMPOUNDS (VOCs)1200+ different VOC’s

q Leads to: Eye, nose, throat irritation, headaches, loss of co-ordination, nausea, damage to liver, kidney, and central nervous system. Some VOC’s cause cancer in human beings

OZONE (O3)Forms in the atmosphere through a series of complex chemical

reactions between oxides of nitrogen (NOx) and hydrocarbons

GOOD OZONEStratospher e, ozone

protects us from the sun’s harmful ultravi olet

radiation

BAD OZONETr oposphere, ground

level ozone can damage lung tissue

and plants

Leads to - Wrinkles on skin, sensitive lungs, increased asthma attacks & daily mortality

One of the most dangerous air pollutants

PARTICULATE MATTER (PM10 & PM2.5)

q Leads to - Premature mortality, chronic respiratory disease, weakening of eyesight. Pre-existing heart or lung or asthmatic patients very sensitive to respirable PM

Study by Rice University

&Houston Fire Department EMS

Direct correlation between out-of-hospital cardiac arrests (OHCA) and exposure to PM2.5 and Ozone

Daily average increase in PM2.5 of 6µg/m3 per day over two days raised risk of OHC A by 4.6%

Each increase of Ozone of 20 ppb over one to three hours also increased OHCA risk, with a peak of 4.4%

HIGH OZONE & HIGH PM2.5 DEADLY CARBON DIOXIDEHigh CO2 is indicator of elevated levels of other pollutants

Leads to - Headaches, dizziness, restlessness, feeling of an inability to breathe, sweating, malaise, visual distortion, nausea / vomiting, loss of consciousness

CARBON MONOXIDE (CO)Combines with hemoglobin in the blood to form carboxyhemoglobin

(COHb) and disrupting oxygen transport.

q Leads to -

SULPHUR OXIDES & NITROGEN OXIDES

Both NO2 & SO2 act mainly as irritants and affect the mucous of the eyes, nose, throat, and respiratory tract.

q SOX Source - Various industrial processes, electrical generation / power generation, space heating, iron heating in industries. Coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide

q NOX Source - Road traffic and combustion processes

We spend 90%+ of our time indoors

If we fix our office & our home, will give our respiratory system the rest it needs to build immunity to fight

the U.S. Departme nt of Energy (DoE)

RESULTS: PBC was found to be at par with the best office buildings in USA in terms of Air Quality. Given the extreme air pollution levels in

the outdoor environment of New Delhi, this is an achievement.

If a person spends 10 hours in oxygenated clean air, there is a 42% probability that their blood oxygen saturation level will go

up by 1%

RESULTS: Breathe Fresh, Feel Fresh

Results: Energy Conservation25

Proving treated fresh air translates to energy savings of upto ~50% in terms of reduced load on HVAC system
