ENERGY CONSERVATION BUILDING CODE

The Energy Conservation Building Code (ECBC), launched on 28 June 2007, is a document that specifies the energy performance requirements for all commercial buildings that are to be constructed in India and is mandated by the EC Act, 2001.

The code is mandatory for commercial buildings or building complexes that have a connected load of 100 kW or greater or a contract demand of 120 KVA or greater.

ECBC is a set minimum energy efficiency standards for design and construction. ECBC encourage energy efficient design or retrofit of buildings so that it does not constrain the building function, comfort, health, or the productivity of the occupants and also have appropriate regard for economic considerations (life cycle costs i.e. construction + energy costs are minimized).

BEE is taking suitable steps to prescribe guidelines for energy conservation building codes. ECBC defines the norms of energy requirement per sq. metre of area and takes into consideration the climatic region of the country, where the building is located. Norms have been developed to cater to 5 different climatic zones in India such as composite, hot and dry, warm and humid, moderate and cold.

PEDA has been very active in the propagation and implementation of the ECBC. Various activities have been planned and executed under the scheme including Energy Audits for Government and Commercial Buildings.

The ECBC provides design norms for:

- Building envelope, including thermal performance requirements for walls, roofs, and   windows, except for unconditioned storage spaces or warehouses.

- Lighting system (Interior and exterior lighting), including day lighting, and lamps and   luminaries performance requirements.

- Mechanical systems and equipment, including ventilating, and air Conditioning.

- HVAC system, including energy performance of chillers and air distribution systems.

- Electrical system and motors.

- Water heating and pumping systems, including requirements for solar hot-water   systems.
 

Griha

GRIHA, an acronym for Green Rating for Integrated Habitat Assessment, is the National Rating System of India. GRIHA has been conceived by TERI and developed jointly with the Ministry of New and Renewable Energy, Government of India. It is a green building 'design evaluation system', and is suitable for all kinds of buildings in different climatic zones of the country.

Indian Green Building Council (IGBC):

Indian Green Building Council (IGBC) is a part of CII-Godrej Green Business Centre, which is actively involved in promoting the Green Building movement in India. The council is represented by all stakeholders of construction industry comprising of corporate, government & nodal agencies, architects, product manufacturers, institutions, etc. The council is industry-led, consensus-based and member-driven. The vision of the council is to serve as single point solution provider and be a key engine to facilitate all Green Building activities in India.
