2. OVERVIEW
2
 India is the fourth largest consumer of energy in the world, but it is only the seventh
largest producer of energy worldwide.
 Approximately 300 million people in India are without access to electricity and another
400 million or so have access only for 5-6 hours a day.

5. NEED FOR ENERGY EFFICIENCY
Buildings contribute to 35 to 40% of commercial energy use globally and (31% in
India), hence GHG emissions as well.
Buildings consume 365 Billion Units in India
Energy efficiency in buildings can save at least 25% of energy,
India is going to build 2 to 3 times of the existing building stock by 2030

6. NEED FOR ENERGY EFFICIENCY
Typical Energy Consumption Pattern
⮚ Most of the existing lighting and air conditioning systems are not very efficient, leaving a wide scope for improvement
in energy performance.
⮚ Overall the energy savings estimates for the commercial and residential buildings vary between 30-70%.
⮚ Challenge before India is to plan and implement energy efficiency measures during the early stages of growth in the
building sector.

7. PROVISION OF EC ACT 2001
Section 15 – Powers of State Government
• Amend ECBC to suit regional and local climatic conditions and may, by rules made by it
specify and notify ECBC with respect to use of energy in the buildings.
Section 18 – Power of Central Government or State Government
• Central Government or State Government may issue directives for efficient use of energy
and its conservation
States have used the powers under EC Act to notify/ issue directives for ECBC
Notification can also be done through amendments in local (municipal) building bye-laws

8. Birth of ECBC
The Energy Conservation Act was enacted on 1st October, 2001.
The Bureau of Energy Efficiency (BEE) was set up on 1st March, 2002.
It is a statutory body under the Ministry of Power, under the provisions
of the EC Act.
The Energy Conservation Building Code (ECBC) was developed by
BEE and launched on 27th May, 2007.
It was revised and relaunched on 19th June, 2017.

9. 9
 The purpose of the Energy Conservation Building
Code (ECBC) is to provide minimum requirements for
the energy-efficient design and construction of
buildings.
 The Code also provides two additional sets of
incremental requirements for buildings to achieve
enhanced levels of energy efficiency that go beyond
the minimum requirements.
PURPOSE OF ECBC

10. 10
SCOPE OF ECBC
 The Code is applicable to buildings or building complexes that have-
Connected load =100 kW or Greater
or
Contract demand = 120 kVA or Greater
or
Conditioned Area = 500m2
and are intended to be used for commercial purposes.
 Buildings intended for private residential purposes only are not covered by the Code.

11. 11
2.1 Energy Efficiency Performance Levels
 The code prescribes the following three levels of energy efficiency:
a) ECBC Building (Energy Conservation Building Code Compliant Building)
b) ECBC+ Building (Energy Conservation Building Code Plus Building)
c) Super ECBC Building (Super Energy Conservation Building Code Building)
SCOPE OF ECBC

REFERENCE STANDARDS
 The National Building Code of India 2016 (NBC) is the reference standard for
1) Lighting Levels,
2) Heating, Ventilating, Air Conditioning (HVAC),
3) Thermal Comfort Conditions,
4) Natural Ventilation,
and any other building materials and system design criteria addressed in this Code

15. 15
The Energy Performance Index (EPI) of a building is its annual energy
consumption in kilowatt-hours per square meter of the building. While calculating
the EPI of a building, the area of unconditioned basements shall not be included.
EPI can be determined by:
𝑎𝑛𝑛𝑢𝑎𝑙 𝑒𝑛𝑒𝑟𝑔𝑦 𝑐𝑜𝑛𝑠𝑢𝑚𝑝𝑡𝑖𝑜𝑛 𝑖𝑛 𝑘𝑊ℎ
EPI =
𝑡𝑜𝑡𝑎𝑙 𝑏𝑢𝑖𝑙𝑡𝑢𝑝 𝑎𝑟𝑒𝑎 (𝑒𝑥𝑐𝑙𝑢𝑑𝑖𝑛𝑔 𝑢𝑛𝑐𝑜𝑛𝑑𝑖𝑡𝑖𝑜𝑛𝑒𝑑 𝑏𝑎𝑠𝑒𝑚𝑒𝑛𝑡𝑠)
COMPLIANCE AND APPROACH
To comply with the Code, buildings shall –
a) have an Energy Performance Index Ratio (EPI Ratio) less than or equal to 1
and, meet all mandatory requirements mentioned under §4.2, §5.2 , §6.2, and §7.2.

16. 16
To comply with the Code, EPI shall
be calculated based on one of the
following:
Prescriptive Method
including Building Envelope
Trade-off Method (see
§3.2.2)
Whole Building
Performance Method (see
§3.2.3)
