1. WESTERN REGIONAL WORKSHOP
FOR ECBC IMPLEMENTATION, PUNE
18TH MAY, 2018
ENERGY CONSERVATION BUILDING CODE

2. About Energy Conservation Building Code
The Energy Conservation Act, was enacted in 2001
Purpose: Provide legal framework and institutional arrangement to embark energy efficiency drive.
This includes Energy Conservation Building Code
Section 15 of the Act empowers Govt. of India and State Governments to modify ECBC as per climatic conditions of states.
Voluntary introduction of ECBC in May 2007, second version launched in June 2017

3. Scope of the code
Applicable to New Commercial buildings (Inclusive Govt. Buildings) having connected load of 100 kW or greater or a contract demand of 120 kVA or greater.
Currently is under voluntary stage
Mandatory notification in progress in different States
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

4. Salient features of ECBC 2017
Technology Neutral
Renewable Energy Integration
Incremental energy performance levels
Applicability to various categories of buildings and Passive Design Strategies.
Additional improvements in higher grades
ECBC plus: 35% or higher
Super ECBC: 50% or higher

7. ECBC 2017: An Integrated Process
EFFICIENT BUILDING
BUILDING DEMAND REDUCTION
EFFICIENT BUILDING SYSTEMS
OFFSET THROUGH RENEWABLES
BUILDING OPERATIONS AND CONTROLS
Insulation of roof & walls
Shading windows
Glass selection (SHGC, u-value, VLT)
Effective daylight in the building
REDUCED ARTIFICIAL LIGHTING REQUIREMENT (due to daylight enhancement)
Low lighting power density of the lighting system
CONTROLS: daylight, occupancy, motion controls, astronomical controls for exterior
System sizing reduced compared to conventional
Efficient systems
System controls
System balancing
Efficient equipment, motors
Power factor correction
Transformers, dg sets
Distribution system
Offset electricity use for hot water requirement of building
Offset electricity form grid by power generation through renewable

8. K.K. Guest House, Bangalore
KEY BENEFITS:
Sizing of HVAC system was reduced
Capacity of DG backup was reduced
Transformer sizing reduced from two KVA units to to 630 KVA
Electrical system planned efficiently and hence cost effective.
Useful daylight in spaces reduced dependence on artificial light during the day.
