1. Green Rating for Integrated Habitat Assessment
GRIHA
Green Rating for Integrated Habitat Assessment

2. GRIHA is a Sanskrit word,literally meaning ‘A house as containing several rooms’.
GRIHA is India’s National Rating System for Green buildings. It has been developed by TERI (The Energy and
Resources Institute) and is endorsed by the MNRE (Ministry of New and Renewable Energy).
seeks to strike a balance between established practices and emerging concepts, both national and international.
GRIHA attempts to minimize:
a building’s resource consumption,
waste generation, and
overall ecological/environmental impact
by comparing them to certain nationally acceptable limits / benchmarks. It does so, adopting the five ‘R’ s-
REFUSE
REDUCE
REUSE
RECYCLE
REINVENT
Tool to facilitate design, construction, operation of a green building ,and in turn ….measure “greenness” of a building in India

Set of 34 criteria focusing on:
•Site Planning
•Building Design
•Energy Efficiency
•Water and waste management
•Sustainable Building Materials
•Occupant Health and comfort
So as to manage, control and reduce /optimize the same to the best possible extent GRIHA assesses a building out of 34 criteria and awards points on a scale of 100. In order to qualify for GRIHA certification, a project must achieve at least 50 points.

6. Why should you get your building rated?
Some of the benefits of a green design to a building owner, user, and the society as a whole are as follows:
1. Reduced energy consumption without sacrificing the comfort levels (lower operational costs)
2. Reduced water consumption
3. Reduced system sizes (HVAC, transformers, cabling, etc.) for optimal performance at local conditions.
4. Reduced investment (lifecycle cost)
5. Reduced destruction of natural areas, habitats, biodiversity, reduced soil loss from erosion etc.
6. Reduced air and water pollution (with direct health benefits)
7. Limited waste generation due to recycling and reuse
8. Reduced pollution loads
9. Increased user productivity
10. Enhanced image and marketability

7. How can you get your building rated?
Evaluation
Project evaluation happens at two broad stages
Pre documentation stage – a team from ADaRSH  (Association for Development and Research of Sustainable Habitats) along with the client’s Design Team meet and determine the points being targeted by the project,.
2. Post documentation stage – all necessary proof through documents for the points targeted under various criteria is submitted and then evaluated by third party regional evaluators, to determine final rating that shall be awarded to the project.
During the construction phase of the project, members of the ADaRSH team carry out three due diligence visits, to check on-site compliance of relevant GRIHA criteria. Once the necessary documentation is uploaded, and systems
commissioned on site, the building is evaluated and rated in a three-tier process.
 The preliminary evaluation is done by a team of experts from ADaRSH.
o The team reviews the mandatory points and checks for compliance. The project is rejected if mandatory criteria are not complied with.
o The team then evaluates the optional criteria and estimates the total number of achievable points.
o All compliance documents are vetted through the appraisal process as outlined by GRIHA.
 The evaluation report is given to members of an evaluation committee, comprising renowned external experts in building and landscape design, lighting and HVAC design, renewable energy, water and waste management, and building materials
 The members independently review and award points
 A provisional GRIHA rating is awarded after evaluation of documents submitted

8. Rating
The final score is presented to the National Advisory Committee comprising eminent personalities and renowned professionals in the field, for approval and award of the final rating.
 The final GRIHA rating is awarded after receipt and evaluation of the post occupancy performance audit reports. The audit is conducted after 1 year of building occupancy.
 The rating awarded is valid for a period of five years from the commissioning of the building.
 GRIHA reserves rights to conduct random audits of any criteria for which points have been awarded
 Queries on rating may be sent to org>, and will be responded to within two working days
The registration fee can be calculated based on the following formula

9. GRIHA and local modifications
GRIHA acknowledges the diverse, multi-cultural, multi-ethnic country that is India. It thus acknowledges that regions
within our great nation vary in terms of climate conditions and geology, and thus resources, and the problems that
result due to their shortage.
Thus, it permits assessment on a percentage rather than and absolute basis.
 Checks applicability of points as per actual site conditions
Retains contextual points and discards others
Significant proof required to ascertain inapplicability
GRIHA and thresholds
In some projects (especially smaller size ones) – Systems required are considerably small, such as
 Hot water requirement <500 litres per day
 Waste water recycling and reuse (<10 KL per day)
 Solid waste recycling and reuse, particularly organic waste <100 kg per day
In such cases, investing in technology intensive solutions may unnecessarily lead to cost increments with poor returns.
At a smaller scale it may be judicious to adopt conventional systems / small-scale resource-efficient systems and
technologies. GRIHA acknowledges this requirement.
GRIHA awards points to significant effort and interventions, since we believe that the solutions need to complement the scale of the problem.

10. For instance, hot-water may not be required in an office complex, especially if it is in a hotter climate such as Chennai. So installing a small solar hot water system in a project in Chennai will not get you points. However, the project will not be marked on those points either.
In such cases, the points will be removed from the denominator itself, so the project shall be marked on a percentage basis out of a lower denominator, maintaining the integrity of the system and awarding points for the significant criteria.
