The document provides information about ECBC (Energy Conservation Building Code), which specifies energy performance requirements for commercial buildings in India. It discusses key aspects of ECBC such as its objectives, scope, components, impact in reducing energy consumption, implementation in various states, and case studies of ECBC compliant buildings showing significant energy savings. ECBC aims to minimize energy use and carbon emissions from buildings through passive design strategies and efficient technologies.

billion units of Electricity.
 One Billion sq.mt. of new Commercial
Buildings to be added by 2030.
 The average lifetime of a building is more
than 50-70 years.
 Energy Efficient Building designs &
technologies can result in energy & cost
savings of upto 30-50%.
 National Energy Savings potential of 300 Bn
until 2030.

42. Energy Codes Scenario - Worldwide

43. ECBC

44.  ECBC, Energy Conservation Building Code is a
document that specifies the energy performance
requirements for all commercial buildings that are
going to be constructed in India and is mandated
by EC Act, 2001.
 The Energy Conservation Act 2001 empowered the
central government to prescribe an Energy
Conservation Building Code (ECBC). ECBC was
launched in May 2007 developed by an Expert
Committee, set up by India’s Bureau of Energy
Efficiency (BEE).
ECBC Introduction

45.  ECBC –Energy Conservation Building Code
 Initially the code has been launched by Bureau of Energy Efficiency
(BEE), Ministry of Power, Govt. of India
 As per the code, State Governments initially amended/amending the
code as per their climatic conditions, temperature, requirements, scope
etc.
 Some of the states have been amended and then notified to make
mandatory use of ECBC in upcoming Commercial Buildings in the
state.
ECBC Notification

46.  The Objective of ECBC is to provide Minimum Requirements for
Energy Efficient Design and Construction of Buildings and their
systems.
 The ECBC is applicable to buildings or building complexes that
have-
• Connected Load in excess of 100kW** OR
• Contract Demand in excess of 120 kVA**
• Recommended for all buildings with conditioned area > 500m2**

56. Estimated Impact (2018-2030)

57.  Estimates based on simulation models indicate ECBC compliant
buildings can use 40 – 60% less energy than conventional buildings.
 At the lowest estimate, this implies an annual
saving of nearly Rs. 6 billion; with new
rates for commercial establishments, this
amount would be far higher.
 It has been estimated that the implementation of ECBC for commercial
buildings with connected load above 100kW, will lead to energy savings
to the tune 65 Million units which can supply electricity to 40,000 rural
families for a year without additional installation of power plants, at
current rate of commercial growth in cities.
Why ECBC?

58. ECBC-R– ECBC for Residential Buildings

59. Eco-Niwas Samhita (ECBC-R) Part-I

60. Implementation of ECBC-R
• Implementation of this Code
will have potential for energy
savings to the tune of 125
Billion Units of electricity per
year by 2030, which is
equivalent to about 100
million ton of Co2 emission.
• While launching this ECBC-R,
Shri R.K. Singh stated that
building sector will have
highest growth in energy
demand in coming 10-15
years.
