The document discusses the role of energy efficiency in smart and sustainable development in India. It makes three key points:
1) Energy efficiency and conservation are essential for India's smart growth and development given its increasing energy demands and imports but also to reduce pollution and meet climate targets. Significant potential exists for energy savings across sectors like industry, buildings, transportation, and agriculture.
2) The Government of India has implemented several initiatives to promote energy efficiency such as building codes, performance standards, audits, awards, and renewable energy targets. However, challenges remain in meeting energy needs while balancing environmental and economic factors.
3) Transitioning to sustainable energy sources like solar, wind, biomass and increasing renewable capacities will be
3. SMART GROWTH/ DEVELOPMENT
Smart Growth or development is a theory of
land development that accepts that growth
and development will continue to occur, and
so seeks to direct it in an intentional,
comprehensive way.
Its proponents include urban planners,
architects, developers, community activists,
and historic preservationists.
The biggest question it poses is โฆโฆ..how
and where should new development be
accommodated ?

4. SMART GROWTH/ DEVELOPMENT
โข Smart growth is a development that serves the economy,
the community, and the environment.
โข Smart growth means
โ Developing sustainable communities that provide a
greater range of transportation and housing choices .
โ Redeveloping underutilized sites and conserving farm
land .
โ Concentrating growth in compact walk able urban
centres to avoid sprawl, thereby saving on services,
reducing pollution & providing better health.
โ Equitable distribution of costs and benefits of
development.
โ Preserving and enhancing natural and cultural resources
and promote public health.

5. APPROACH TO SMART GROWTH/
DEVELOPMENT
Smart growth can be achieved by
โข Mix land use and compact building designs.
โข Increasing housing density along transit nodes.
โข Restrictions or limitations on suburban design forms
(e.g., detached houses on individual lots, strip malls and
surface parking lots) supporting existing communities.
โข Enhancing economic competitiveness.
โข Providing more transportation choices.
โข Promoting equitable and affordable housing by
redefining housing affordability and making the
development process transparent.
โข Encouraging community and stakeholder collaboration in
development decisions 5
6. CRITICISM OF SMART GROWTH/
DEVELOPMENT
โข The phrase "smart growth" implies that other
growth and development theories are not
"smart".
โข Smart growth policies disfavour minorities /
people with average incomes and the poor
due to driven up housing prices.
โข There is no evidence after ten years that
smart-growth have had any effect on
development patterns.
โข โSmart growth" is mostly an illusion.

7. ENERGY AND SUSTAINABLE DEVELOPMENT
โข Energy is the most essential factor for sustainable
development and poverty eradication.
โข India has 306.2 million people without electricity, and 705
million people who rely on wood and biomass for cooking.
โข 4.3 million people are dying prematurely ( mostly women
and children) every year due to indoor pollution resulting
from cooking and heating using unsustainable fuels.
The challenge lies in
๏finding ways to reconcile the necessity and demand for
modern and sustainable energy services.
๏their impact on the environment and the global natural
resources.

18. ENERGY SAVINGS FOR BUILDINGS
โข Reducing heating demand
โ Heating demand can be reduced by limiting the exposed surface
area of the building, improving the insulation of the buildingโs
envelope, reducing ventilation losses by selecting efficient heating
systems with effective controls.
โข Reducing cooling demand
โ Energy use in typical air-conditioned office buildings is
approximately twice of naturally ventilated office buildings. Cooling
demand can be reduced by controlling solar gains through glazing,
reducing internal heat gains, setting AC thermostat at 25-26oC
instead of 23-24oC, making use of thermal mass and night
ventilation, reducing lighting loads and installing effective lighting
controls.
โข Reducing the energy requirements for ventilation
โ The main use of energy for both mechanical cooling and for air
conditioning is the fans needed to circulate the air which can be
reduced by designing the system to reduce pressure drops,
selecting efficient fans, utilizing variable speed fans to respond to
varying load requirements, avoiding excessive air supply volumes,
etc. 19
19. ENERGY SAVINGS FOR BUILDINGS
โข Reducing energy use for lighting
โ This can be accomplished through making maximum
use of daylight while avoiding excessive solar heat gain,
using task lighting ,installing energy-efficient luminaries,
selecting lamps with a high luminous efficacy, providing
effective controls like occupancy sensors.
โข Reducing energy used for heating water
โ This can be achieved by installing time controls, and
setting them to correctly reflect the hours of hot water
requirement, replacing any damaged or missing
insulation from hot water pipes and cylinders and by
solar water heating.

โข Energy efficiency is the easiest way to reduce the demand -
supply gap.
โข There is huge scope for improving energy efficiency levels in
Indian industries, thermal power plants , household, agriculture,
and transport sector.
โข Use of renewable energy sources, mandating net zero buildings
and single window clearance for energy efficiency projects can
convert the dream of smart & sustainable development into reality.
โข Promoting awareness about energy conservation and energy
efficiency, mandating use of BEE standard energy efficient pumps
in agriculture sector, as well as shut down of power plants having
very low efficiency and gradually replacing them with energy
efficient ones is liable to contribute to good amount of energy
savings.
โข Use of renewable energy potential and ultimately complete shift to
