  • The GRIHA Council has been working persistently since 2005 to enhance sustainability of our built environment with more than 2000 registered projects under various GRIHA variants with a combined footprint of over 850 million m2 spread across the country. These projects account for about 2525 MW of installed renewable energy generation capacity to offset 28.2 MtCO2/annum emissions.
  • The GRIHA v.2015 has undergone an extensive revision in order to account for the ongoing advancements in the highly dynamic construction sector.
  • Recently, Government of India has revised several standards such as ECBC 2017, NBC 2016, and so on, and has also introduced guidelines for waste management. These revised standards have been well addressed in the varied requirements of GRIHA v.2019 such that it acts as a single scheme that can empower and push towards global sustainable development goals.

Eligibility

  • All new construction projects with built up area more than 2500 m2 (excluding parking, basement area, and typical buildings) are eligible for certification under GRIHA v.2019. Building typologies have been further defined in the subsequent sections.

Note – Typical buildings can be defined as the ones with exact same orientation, height, floor plan, and plinth level and are constructed within a defined site boundary

1) Rating process

i) Online registration

  • The project team can initiate the registration process by filling the EOI Form available on the GRIHA website.

  • Once the project is registered, the project team is provided with a username and password for submitting the documentation on the GRIHA online panel.

ii) Orientation workshop

  • The registration is followed by an orientation workshop conducted by GRIHA Council officials, which intends to provide detailed information of the rating along with an elaborate explanation to all the criteria, and post addressing project-specific queries of the teams.

iii) Due diligence I

  • The site visit shall be conducted by GRIHA Council officials to validate sustainable measures adopted during the construction phase.
  • It will be scheduled post the project has reached its plinth level.
  • The Due diligence report should be uploaded on the panel within 20 working days from the site visit, followed by an uploading of a compliance report by the project team within the next 15 working days.
  • This is to ensure that the project abides by the mandatory requirements of the rating.

iv) Due diligence II

  • The second site visit shall be conducted by the GRIHA Council officials to validate internal finishes, electrical, plumbing, and mechanical components installed during the construction phase.

vi) Preliminary evaluation

  • After the online submission of the documents, the preliminary evaluation is carried out by a team of professionals from GRIHA Council and external evaluators, who are experts in their respective fields recognized by GRIHA Council.

  • On the basis of this evaluation, The GRIHA Council shall prepare a final score card within 30 working days after the project team furnishes requisite information sought during preliminary evaluation and due diligence visits.
  • The final rating is awarded based on the final evaluation and is valid up to 5 years.

ix) Additional due diligence Green awareness drive

  • The GRIHA Council conducts an additional due diligence visit post the final rating, for green awareness and education amongst project occupants.
  • This visit aims to impart basic knowledge and understanding on green buildings and their way of working.
  • This awareness programme could be organized within 12 months of occupancy of the project.

x) Rating renewal

  • There are two ways in which the rating can be renewed and the project gets to enjoy the perks of being called a rated building.
  • This can be done either by submitting an audit data report (over a span of three consecutive years) comprising energy, water, and waste (report to be prepared by BEE-certified energy auditor), or by enrolling the project for GRIHA EB rating to maintain its certification for the next cycle of 5 years.

Notes-

  1. If the project fails to comply with any mandatory requirement/s of the rating, in such a scenario, it shall be denied rating.
