IGBC Rating System

Indian Green Building Council  (IGBC) has developed green building rating programmes to cover commercial, residential, factory buildings, etc., Rating programmes would help projects to address all aspects related to environment and is an effective tool to measure the performance of the building/ project.

IGBC rating system addresses green features  under the following categories:

  • Site Preservation & Restoration
  • Site Planning & Design
  • Water Efficiency
  • Energy Efficiency
  • Materials & Resources
  • Innovation & Design Process

Different rating systems under IGBC certification are:

  • IGBC Green Homes rating system
  • IGBC Green Factory Building rating system
  • IGBC Green SEZ Rating System

Each rating system divided int to different levels of certification are as follows.

‘Certified’ to recognise best practices
‘Silver’ to recognise outstanding performance
‘Gold’ to recognise national excellence
‘Platinum’ to recognise global leadership

The threshold criteria for certification levels changes with rating systems.

IGBC Green Homes Rating System:
Indian Green Building Council (IGBC) Green Homes is the first rating programme developed in India, exclusively for the residential sector. It is based on accepted energy and environmental principles and strikes a balance between known established practices and emerging concepts. The system is designed to be comprehensive in scope, yet simple in operation.

Benefits of Green Homes

A Green Home can have tremendous benefits, both tangible and intangible. The immediate and most tangible benefit is in the reduction in water and operating energy costs right from day one, during the entire life cycle of the building.

Eligibility

IGBC Green Homes Rating System is a measurement system designed for rating new residential buildings which include construction categories such as

Individual homes

High rise residential apartments,

Gated communities

Row houses

Existing residential buildings which retrofit and

redesigned in accordance with the IGBC Green Homes criteria.

IGBC Green Homes Process:

The project team can evaluate all the possible points to apply under the rating system using a suitable checklist. The project can apply for IGBC Green Homes certification if it can meet all mandatory requirements and achieve the minimum required points.

Green Home should meet certain mandatory requirements, which  are non-negotiable.

The various levels of rating  awarded are:

The rating system  caters to  projects like individual houses, apartments, motels,  resorts, hostels, etc., Amongst the different types, projects are broadly classified into  two categories:

Projects where interiors are part of scope of work

Projects where interiors are not part of  the scope of work

Interiors include but not limited to materials like interior finishes & furniture and appliances like refrigerators, fans, lights etc., As a general guideline, individual  owners can use the checklist ‘Projects with Interiors’ and developers & builders can  use the checklist titled ‘Projects without Interiors’. However, if the context varies,  projects can adopt the one which is the closest fit.

Certification Level Points for projects with interiors Points for projects              without interiors
Certified 32 – 39 30 – 36
Silver 40 – 47 37 – 44
Gold 48 – 59 45 – 55
Platinum 60 – 80 56 – 75

IGBC Green Factory Building rating system

GBC Green Factory Rating System is a voluntary and consensus based programme. The rating system has been developed based on the contemporary materials and technologies. This rating system would facilitate the development of green factories. The rating system evaluates certain credit points using a prescriptive approach and other credits on a performance based approach. The rating system is evolved so as to be comprehensive and at the same time user-friendly.

The existing factory buildings should address the following measures (illustrative) before applying for certification:

  • Soil erosion control measures in future
  • Changes in design to accommodate requirements of differently abled people, like
  • easy access to lifts, rest rooms etc.,
  • Change to low flow water fixtures
  • Rainwater harvesting
  • Limit turf areas
  • Have policy for use of green materials in future
  • Minimum fresh air ventilation
  • Comfort conditions
  • Use eco-friendly housekeeping materials

The rating system is valid for 3  years. On completion of 3 years, projects can validate  /renew based on the prevailing latest version.

IGBC Factory Building Certification Levels:

IGBC Green SEZ Rating System-Pilot Version
IGBC along with the Ministry of Commerce and Industry (MoCI) has prepared the Green SEZ guidelines. IGBC has further developed IGBC Green SEZ Rating System as an extension of the Green SEZ guidelines which encourages the projects to exceed the requirements of many codes and standards.

The rating system has been developed based on materials and technologies that are presently available. The objective of IGBC Green SEZ is to facilitate the creation of energy efficient, water efficient, healthy, comfortable and environmentally friendly SEZ.

The rating system evaluates certain credit points using a prescriptive approach and other credits on a performance based approach. The rating system is evolved so as to be comprehensive and at the same time user-friendly.

The rating programme uses well accepted national standards and wherever local or national standards are not available, appropriate international benchmarks have been considered.
