Evaluation procedure of criterion of GRIHA, an Indian rating system
GRIHA objective and its criteria
Green building rating will evaluate the environmental performance of a building holistically over its entire life cycle, thereby providing a definitive standard for what constitutes a ‘green building’. The rating system , based on accepted energy and environmental principles, will seek to strike a balance between the established practices and emerging concepts, both national and international. The guidelines/criteria appraisal may be revised every three years to take into account the latest scientific developments during this period.
On a broader scale, this system, along with the activities and processes that lead up to it, will benefit the community at large with the improvement in the environment by reducing GHG (greenhouse gas) emissions, improving energy security, and reducing the stress on natural resources.
Some of the benefits of a green design to a building owner, user, and the society as a whole are as follows:
Currently the system has been developed to help ‘design and evaluate’ new buildings (buildings that are still at the inception stages). A building is assessed based on its predicted performance over its entire life cycle – inception through operation. The stages of the life cycle that have been identified for evaluation are the pre-construction, building design and construction, and building operation and maintenance stages. The issues that get addressed in these stages are as follows.
The criteria have been categorized as follows.
Site Selection and Site planning
Conservation and efficient utilization of resource
Objective – To maximize the conservation and utilisation of resources (land, water, natural habitat, avi fauna, and energy) conservation and enhance efficiency of the systems and operations.
Commitment Proper timing of construction, preserve top soil and existing vegetation, staging and spill prevention and erosion and sedimentation control. Replant, on-site, trees in the ratio 1:3 to those removed during construction.
Commitment Proper top soil laying and stabilization of the soil and maintenance of adequate fertility of the soil to support vegetative growth.
Commitment Minimize the disruption of natural ecosystem and design to harness maximum benefits of the prevailing micro-climate.
Commitment Minimize storm water run-off from site by reducing hard paving on- site.
Commitment Meet minimum allowable luminous efficacy (as per lamp type) and make progressive use of a renewable energy- based lighting system.
Commitment Minimize road and pedestrian walkway length by appropriate planning and provide aggregate corridors for utility lines.

Objective –To protect the health of construction workers and prevent pollution.
Commitment Ensure cleanliness of workplace with regard to the disposal of waste and effluent, provide clean drinking water and latrines and urinals as per applicable standard.
Commitment Ensure proper screening, covering stockpiles, covering bricks and loads of dusty materials, wheel-washing facility, and water spraying.
Building planning and construction stage
Conservation and efficient utilization of resources
Objective – To maximize resource (water, energy, and materials) conservation and enhance efficiency of the system and operations.
Water
Commitment Landscape using native species and reduce lawn areas while enhancing the irrigation efficiency, reduction in water requirement for landscaping purposes.
Commitment Reduce building water use by applying low-flow fixtures, etc.
Commitment Use materials such as pre-mixed concrete for preventing loss during mixing. Use recycled treated water and control the waste of curing water.
Energy: end use
Commitment Plan appropriately to reflect climate responsiveness, adopt an adequate comfort range, less air-conditioned areas, daylighting, avoid over-design of the lighting and air-conditioning systems.
Commitment Ensure that energy consumption in building under a specified category is 10%–40% less than that benchmarked through a simulation exercise.
Energy: embodied and construction
Commitment Use of fly ash for RCC (reinforced cement concrete) structures with in-fill walls and load bearing structures, mortar, and binders.
Commitment Replace a part of the energy-intensive materials with less energy-intensive materials and/or utilize regionally available materials, which use low-energy/energy-efficient technologies.
Commitment Minimum 70% in each of the three categories of interiors (internal partitions, panelling/false ceiling/interior wood finishes/ in-built furniture door/window frames, flooring) from low-energy materials/finishes to minimize the usage of wood.
Energy: renewable
Commitment Meet energy requirements for a minimum of 10% of the internal lighting load (for general lighting) or its equivalent from renewable energy sources (solar, wind, biomass, fuel cells, etc). Energy requirements will be calculated based on realistic assumptions which will be subject to verification during appraisal.
Commitment Meet 70% or more of the annual energy required for heating water through renewable energy based water-heating systems.

Scoring points for TERI–GRIHA
TERI–GRIHA is a guiding and performance-oriented system where points are earned for meeting the design and performance intent of the criteria. Each criterion has a number of points assigned to it. It means that a project intending to meet the criterion would qualify for the points. 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 for example : energy consumption, thermal and visual comfort, noise control criteria, 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 to firm points through monitoring, validation, and documents/photographs to support the award of point.
TERI-GRIHA has a 100 point system consisting of some core points, which are mandatory to be met while the rest are optional points, which can be earned by complying with the commitment of the criterion for which the point is allocated. Different levels of certification (one star to five star) are awarded based on the number of points earned. The minimum points required for certification is 50. Buildings scoring 50 to 60 points, 61 to 70 points, 71 to 80 points, and 81 to 90 points will get one star, ‘two stars’, ‘three stars’ and ‘four stasr’ respectively. A building scoring 91 to 100 points will get the maximum rating viz. five stars.
| Points scored | Rating |
| 50–60 | One star |
| 61-70 | Two star |
| 71-80 | Three star |
| 81-90 | Four star |
| 91-100 | Five star |
