GRIHA for Existing Building (EB) rating is an integrated tool to assess the performance of existing buildings and provide sustainable solutions whilst augmenting the indoor comfort of the occupants. The rated buildings will enjoy enhanced energy and water performance and increased thermal and visual comfort; ultimately resulting in decreased operational and maintenance costs. The rating endeavors to provide solutions to various typologies and ages of building catering to the diverse climatic zones of India, and include RWAs & users of habitats in the process.
GRIHA Existing Buildings Rating
Introduction
Intent
GRIHA for Existing Buildings rating is designed with underlining objectives, such as attaining environmental impact reduction, simplicity in execution, alignment with local and national goals, and cost effectiveness.
Salient Features
Designed specifically for existing buildings
GRIHA EB is specifically designed to assess and improve the environmental performance of existing buildings which evaluates buildings based on operational performance.
Supports goals of Government commitments
These commitments include reducing the economy's emission intensity by 45% by 2030 (from 2005 levels), achieving 50% of installed electricity capacity from non-fossil fuel sources by 2030, and creating an additional carbon sink of 2.5-3 billion tonnes of CO2 equivalent by 2030 through forestation and reforestation.
Encourages Retrofitting
Promotes retrofitting and improvement of old systems (like HVAC, lighting, plumbing) to enhance sustainability.
Benefits/Advantages of adopting GRIHA Existing Buildings Rating
User friendly and easy to implement
With minimum requirements for extensive documentation, the rating is suitable for operational buildings, including those with limited resources or stakeholder involvement.
Enhanced recognition
Rating under GRIHA EB highlights the building’s commitment to sustainable operation and maintenance, improving its visibility, credibility, and market value. The commercial buildings especially stand to benefit even more with the optimized value of the property cost and increased tenant retention of the rated buildings.
Optimised operational and maintenance cost
The rated buildings will enjoy enhanced energy and water performance and increased thermal and visual comfort, ultimately resulting in decreased operational and maintenance costs.
Educates Building Occupants and Staff
The rating is designed to emphasize the importance of occupant awareness in achieving sustainability goals. The rating process includes awareness sessions, workshops, and training to educate the building users (occupants, tenants), maintenance staff and housekeeping and support teams.
