GRIHA RATING

All GRIHA Rating variants undergo periodical technical revisions under the supervision of GRIHA Technical Advisory Committee (TAC). The latest version of GRIHA, GRIHA version 2015 (GRIHA V2015), was introduced in January 2015.

The registration in GRIHA Version 3 is open only till 31st December 2017, post this, the projects will have to be registered in Version 2015.

GRIHA Version 2015


The GRIHA V 2015 rating system consists of 31 criteria categorized under various sections such as Site Planning, Construction Management, Occupant Comfort and Wellbeing, Sustainable Building Materials, Performance Monitoring and Validation, and Innovation.

Eligibility

All buildings, which are in the design stage and have built up area more than 2,500 m2, are eligible for certification under GRIHA. Building types include, but are not limited to offices, retail spaces, institutional buildings, hotels, hospital buildings, healthcare facilities, residences, and multi-family high-rise buildings.

Criteria and their weightage

GRIHA is a performance-oriented system where points are earned for meeting the design and performance intent of the criteria. Each criterion has certain points assigned to it. It means that a project demonstrating compliance with a criterion would achieve the associated points.

GRIHA is a 100-point system consisting of some core points, which are mandatory, while the rest are optional. Different levels of certification (one star to five stars) are awarded based on the number of points earned. The minimum points required for certification are 25.

The scores for achieving GRIHA rating have been revised. The new thresholds for achieving GRIHA rating are mentioned below:

GRIHA Version 3


GRIHA V 3 rating system consists of 34 criteria covering various subjects such as sustainable site planning, energy and water optimization, sustainable building materials, waste management and building operations & maintenance. There are bonus points for strategies implemented over and above the listed GRIHA Criteria.

Eligibility

All buildings, which are in the design stage and have built up area more than 2,500 m2, m2, which are in the design stage, are eligible for certification under GRIHA. Building types include but are not limited to offices, retail spaces, institutional buildings, hotels, hospital buildings, healthcare facilities, residences, and multi-family high-rise buildings.

Compliances, as specified in the relevant criterion, have to be submitted in the prescribed format. While the intent of some of the criteria is self-validating in nature, there are others such as energy consumption, thermal and visual comfort, noise control, and indoor pollution levels which need to be validated on-site through performance monitoring. The points related to these criteria (specified under the relevant sections) are awarded provisionally while certifying and are converted into firm points through monitoring, validation, and documents/photographs to support the award of point.

Rating Process

i. Registration
A project must be registered with GRIHA Council through the GRIHA website by filling in the registration form online. Registration should preferably be done at beginning of a project, as several issues need to be addressed at the pre-design stage. The registration process includes access to the essential information related to rating.

ii. Post-registration workshop
An orientation workshop is conducted by the GRIHA Council, for the entire project team comprising of the owner, architect, MEP Consultants, landscape consultants, project manager, etc. The workshop serves the dual purpose of awareness of GRIHA System for all involved and identification and evaluation of the optional criteria to enhance the rating of the project.

iii. Online Submission of documents
The project proponent is required to provide documentary evidence to demonstrate compliance with the criteria. The required list of documents is mentioned in the criteria in the GRIHA Manual. All compliance documents shall be submitted through the online portal on the GRIHA website. Submitted documents will be checked and vetted by GRIHA Council.

iv. Due Diligence
Three site visits will be conducted as part of the rating process to verify the compliances on site. The first site visit will be done when the project is at plinth level, the second one will be done when the structural work is complete and interior finishing is in progress. The third and final site visit will be done after the preliminary document assessment by GRIHA.

v. Evaluation process
Complete and consolidated rating documents submitted by the project proponent shall be sent for a third-party review. Third party reviewers are identified and trained by the GRIHA Council under the supervision of the Technical Advisory Committee of GRIHA. On-site checks will be carried out by the GRIHA Council 3 times during the project execution phase for auditing the green features as part of the Due-Diligence visits.

Once rated, the rating will be valid for a period of five years from the date of commissioning of the building. GRIHA reserves the right to undertake a random on-site audit of any criteria for which points have been awarded.

Note: It may please be noted that rating is subject to fulfilment of minimum requirements as necessary under GRIHA. Projects that do not fulfil mandatory criteria and minimum required optional criteria are not eligible for rating.

Certification fee

The registration cum rating fee (subject to review and modification) is as follows:

For registration fees details - click here

The fee includes:

A third-party, post-occupancy (at the operational stage) audit is to be conducted for the confirmation of provisional rating after 12 months. A BEE certified energy auditor shall be appointed by the project proponent to conduct the audit. This is not included in the GRIHA cost.

If the preliminary assessment or workshop or site visits are out of station for New Delhi, all expenditure incurred on travel by flight (to & fro) and accommodation shall be arranged by the project proponent. Two members from GRIHA Council will conduct 3 site visits, in the beginning of the project, middle and towards the end of the project execution stages. Their travel and accommodation arrangements will have to be made by the client.

Government taxes as applicable during registration are added to registration and rating fees.

It may be noted that award of the rating is subject to fulfilment of all requirements as elaborated in GRIHA document.
