The document discusses the critical role of energy efficiency as a national resource, emphasizing its connection to water use in India and the expected increase in global energy consumption. It highlights the need for innovative building solutions, such as the use of white roofs for energy savings and the development of energy-efficient buildings like the Paharpur Business Centre and Greenspaces project. Additionally, it stresses the importance of promoting energy efficiency through education and investment, particularly targeting future generations.

1. The Potential
of
‘Energy Efficiency’

2. World energy outlook
• World marketed energy consumption is
expected to grow by 49 percent from 2007 to
2035
• Coal consumption is expected to grow at 1.1%
per year from 2007‐ 2020 and 2% per year
from 2020 ‐ 2035
• Oil consumption worldwide is expected to
grow by 1.4% per year from 2003 ‐ 2030
• Global electricity consumption is set to
explode to over 30 trillion kWhrs by 2030
growing @ 3.6 % annually

3. Energy efficiency ‐ a Resource
Energy efficiency should be treated as a
National Resource, similar to coal and oil

4. Strong linkage between energy used
and water in India
• In India, there is a direct link between water
and energy efficiency on account of use of
energy inefficient pumps to extract
groundwater for agriculture
• A 33% shortfall of water has been projected
for India by 2050

5. Benefit Plus with time
Benefits of energy efficiency will increase
with rising demand and cost of energy

6. A simple low cost solution
• Color of Green is White
• White color reflects light and heat into space
• For centuries, India has practiced this principle
• It is similar to India’s discovery of ‘Zero’
• If one visits the Mehrangarh Fort in Jodhpur
and look down, one will only see white or blue
rooftops, painted with lime wash

7. The Color of Green is White
• In support, U.S.A Energy Secretary, Dr. Steven
Chu says, “Make it white”
• Lawrence Berkeley National laboratory (LBNL)
estimates worldwide energy savings of $27
billion/ year with cool white roofs (2008)

8. Buildings and Energy
• Energy demand is set to increase by 30% in the
next 10 years
• Buildings account for 40% of all the energy used
by humans on the planet
• 60% of human population will be living in cities in
the next 15 years
• It is said that 2/3 of India is yet to be built
It will need over 10 million new homes each year
for the next two decades
• In urban areas, there is growing preference for
working and living in air‐conditioned spaces
• We need to be more energy, water and waste
efficient in buildings of all sorts

9. Our project #1
• Paharpur Business Centre & Software
Technology Incubator Park – a 50,000 ft,2
a 23 year old building in New Delhi, India
• It is a Bureau of Energy Efficiency, Ministry of
Power, Govt. of India, 5 star rated building,
with certified annual average electricity
consumption 2.6 W /hr /ft2
• It expects to be the first retrofit, USGBC LEED
“EB” Platinum certified green building in India,
by December 2010
• Currently there are only 14 Platinum EB rated
buildings of USGBC, worldwide

10. Our project #2
• GreenVilla TM
• A guest house in NCR Delhi, India being
built as a Indian Green Building Council
(IGBC) ‘Platinum’ rated Green Home with a
cost < USD 45 per sq. ft including
furnishing but excluding land cost to be
ready by March 2011
10

11. Our project #3
• GreenSpacesTM
• Being built as world’s most energy efficient
commercial building of 1.75 million ft2 to be
ready for occupation by March 2014
• It is a reference Flagship Project of the Asia
Pacific Partnership (of seven countries) –
Australia, Canada, China, India, Japan, South
Korea, & USA
• To contribute to reduce cost and improve
energy efficiency anyone can partner with us:

13. Reaching out to Children ‐ our future
• I am a trustee of Nobel Laureate Al Gore’s,
‘The Climate Project – India’
• We are taking the climate message to 1 million
school children in New Delhi, in collaboration
with Delhi Government, by March 2011.
• It will be replicated in other places

14. Ways to promote Energy efficiency
as a resource
• Incentivize investment in energy efficiency
• Ban the use of inefficient GLS lamps
• “One way to stop the climate crisis is to
figure out the real costs of adding more
carbon dioxide to the air, then include
those costs in the price of fossil fuel,” Al
Gore, in ‘Our Choice’
