INDOOR AIR QUALITY THERMAL COMFORT &
ENERGY EFFICIENCY
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

Sponsored by the Assistant Secretary for Energy Efficiency and Renewable Energy, Office of Building Technology, State, and Community Progra ms, of
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
