GREEN BUILDING RATINGS IN INDIA
‘GRIHA’ Rating System:
Criteria and their weightage
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 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.
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 is 50.
