the Key for Sustainable Development
Energy Efficiency is the Key for Sustainable Development
- In India the electrification of households has taken place on a
massive scale and demand for energy has increased. One of the key reasons
for this has been the growing population.
- Another is the enormous increase in energy intensive economic
activities. As the conventional sources of energy are reducing and the
renewable sources are under developing phase, improving energy efficiency at
all levels of the energy spectrum is the cost-effective and quick solution
to address this problem.
- Some of the concerns regarding the limitations imposed on
sustainable development by environmental emissions and their negative
impacts can in part be overcome through increased energy efficiency.
- The government, through Nationally Determined Contributions has
aimed to reduce emission intensity of GDP to 33-35 per cent below what it
was in 2005 by 2030.
- However, to achieve this target there is a need for a concerted
move to ensure increased efficiency especially in 3 sectors:
- Industrial sector,
- Real estate,
- Consumer appliance.
Industrial sector continues to be the highest energy consuming domain where
energy conservation would play a vital role. There is also huge potential for
energy conservation and technology enhancement for efficiency in key intensive
industries. With an aim of energy efficiency improvement, Bureau of Energy
Efficiency ( BEE ) is implementing Perform, Achieve and Trade ( PAT) scheme
under the National Mission for Enhanced Energy Efficiency (NMEEE).
Real Estate Sector
The Bureau of Energy Efficiency ( BEE ) envisages a phased approach for
developing an energy conservation code for the residential sector. The idea is
to create a simple and implementable code focusing building envelope which can
be integrated with the existing building codes and bye-laws.
The design of the building envelope will have a direct impact on:
- Heat conduction through the roof , opaque wall and glazed windows
- Solar radiation gains through glazed windows
- Natural ventilation
The real estate sector consumes over 30 percent of the total electricity
consumption in India annually and is second only to the industrial sector as the
largest emitter of greenhouse gases; of which around 75 per cent is used in
The building envelope thus will impact both the thermal comfort as well as
electricity used for space conditioning. In this context, BEE has two programs
(1) Eco Samhita, (Energy Conservation Building Code for Residential
(2) Labelling for Energy Efficient Homes.
Eco Samhita, (Energy Conservation Building Code for Residential Buildings):
The Eco-Niwas Samhita (Part I: Building Envelope) aims to set minimum building
envelope performance standards to limit heat gains (tor cooling dominated
climates) and to limit heat loss (for heating dominated climate) as well as for
ensuring adequate natural ventilation and day lighting. The code is applicable
to all residential use building projects built on plot area >= 500 m2. The code
has been developed with special consideration for its adoption by the Urban
Local Bodies (ULBs) into building bylaws. This strategy enables most of the new
urban housing stock to be brought into the net for capturing the opportunities
and the benefits of energy efficiency in residential buildings.
Labeling Programme for Energy Efficient Homes
- To enable consumers to compare building performances from a
sustainable energy point of view
- a comprehensive labeling scheme is import.
- The objective of proposed labeling programme is mentioned below:
- To provide information to consumers for EE Homes
- Energy sustainability for India
- To achieve Indian NDC Targets
- Market Transformation for energy efficiency in the housing sector.
- It shall act as an embryo to stimulate the larger energy-efficient
materials and technologies market. To seek the energy efficiency label,
customers shall demand energy efficient building materials which in turn,
would give enough impetus to suppliers to produce the same.
- After implementation of the labeling mechanism, the housing value
chain would encourage an additional set of professionals to expedite the
complete process of residential label granting. This way, the labelling
regime shall also be a stimulant for the Indian job market.
- It will also motivate material manufacturers to invest in energy
efficient material manufacturing in India.
- Labelling mechanism shall cause a reduction in energy bills. This
will empower individuals with
- a greater disposable income that can be consumed at other avenues,
saved for future contingencies or invested for cash generating asset
creation for overall economic growth.
- It helps the nation in working towards fulfillment of Global
Sustainable Development Goals 7 of the United Nations: Affordable and Clean
