Regulatory Framework for Energy

Efficiency in India Energy Conservation Act, 2001

Created Bureau of Energy Efficiency

Appliance standards and labeling

Energy consumption norms, and energy-use reporting requirements for

energy-intensive industrial units

Energy Conservation Building Code for commercial buildings

Certified Energy Managers and auditors

National Action Plan for Climate Change, 2008

National Mission on Enhanced Energy Efficiency provides mandate for

market-based mechanisms to promote energy efficiency

National Mission on Sustainable Habitat seeks to incorporate energy-

efficiency requirements in building byelaws

• Ensures Comfort

• Ensures Safety

• Desirable but not mandatory provisions for Energy Efficiency

Design Standards

NBC/ Municipal Building bye-laws

• Energy Conservation Building Code

Energy Standard

Linkage of NBC with ECBC

Harmonization of ECBC

with NBC 2005 has been

finalized by including a

chapter “Approach to

Sustainability” which

would be adopted in all

future constructions in

the country.

Policy and Regulatory Framework for

New Buildings

Energy Conservation Building Code

ECBC covers the following components:

Building Envelope (Walls, Roofs, Windows)

Lighting (Indoor and Outdoor)

Heating Ventilation and Air Conditioning (HVAC) System

Solar Hot Water Heating

Electrical Systems

Voluntary introduction of ECBC in May 2007; mandatory after capacity building and implementation experience

While the ECBC has been developed by BEE, its enforcement lies with the State governments and urban local bodies through notification within their states as per their regional requirements.

ECBC – Status of adoption by States

States that have notified ECBC

States in the process of notification

Outcomes

Institutionalization of training & capacity building (MasterTrainers) *MNIT Jaipur *CEPT Ahmedabad *IIIT Hyderabad

ECBC Cells established in 9 States: *Uttar Pradesh *Karnataka *Haryana

*Chhattisgarh *Bihar *Punjab

*Odisha *Maharashtra *Madhya Pradesh

Harmonization of ECBC with National Building Code

Model building byelaws for ECBC framed and circulated to States

Energy efficient design templates for public buildings developed

Design Guidelines for ‘Energy-Efficient Multi-Storey Residential Buildings’

ECBC Rules developed and circulated to States

‘’Energy Benchmarks for Commercial Buildings’’ developed

Manual for Energy efficiency upgrades in existing buildings for retrofits

Rating programmes - GRIHA & LEED have spurred the market for green

buildings

Regulation to provide the PUSH factor.

70% of commercial space yet to be built.

Electricity consumption in residential sector will spur the demand.

Rapid urbanization.

Increase in demand for space cooling due to shift to ACs.

Energy efficiency up-grades in public buildings on a business model

Rating programs for buildings to provide PULL factor.

Opportunities Ahead
