In India, the Green Interior rating system is part of the broader initiative to promote sustainable practices in interior design and construction. This rating system assesses the environmental performance of interior spaces based on specific criteria and is a subset of the green building rating systems.

IGBC Green Interiors Rating System
The IGBC Green Interiors Rating System is designed to encourage sustainable practices in the interior design of spaces such as offices, retail, hotels, homes, and hospitals. The system evaluates projects based on several key criteria or “credits,” each focusing on different aspects of sustainability. Below is an overview of the credits:
To promote the adoption of sustainable design practices from the early stages of the project.
- Integrating sustainability principles into the project planning and design.
- Minimizing the environmental impact of the interior space through thoughtful design choices.
- Encouraging the use of passive design strategies to reduce energy and resource consumption.
To reduce water consumption within the interior space through efficient fixtures, fittings, and systems.
- Use of low-flow fixtures (e.g., faucets, toilets, showers) that reduce water use.
- Implementation of water recycling and reuse systems, such as greywater systems.
- Monitoring and metering of water usage to ensure ongoing conservation.
- Use of water-efficient landscaping and irrigation systems in interior spaces like atriums.
To reduce the energy consumption of the interior space and promote the use of renewable energy.
-
- Installation of energy-efficient lighting, HVAC systems, and appliances.
-
- Use of renewable energy sources, such as solar panels, to power interior systems.
-
- Implementation of intelligent building systems that optimize energy use, like sensors and automated controls.
-
- Encouraging the use of natural light through design elements like large windows and skylights.
To promote the use of environmentally friendly, sustainable materials in interior spaces
-
- Use of materials with low Volatile Organic Compound (VOC) emissions to improve indoor air quality.
-
- Selection of materials that are recycled, rapidly renewable, or locally sourced to reduce the environmental footprint.
-
- Avoiding the use of materials that have a high environmental impact, such as those that contribute to deforestation or habitat destruction.
-
- Encouraging the reuse of existing materials and furniture to minimize waste.
To ensure a healthy, comfortable, and productive indoor environment for occupants.
-
- Ensuring adequate ventilation and indoor air quality through proper design and HVAC systems.
-
- Maximizing natural daylight and views to the outside, improving occupant well-being.
-
- Controlling indoor temperature, humidity, and noise levels to enhance comfort.
-
- Reducing the presence of indoor pollutants by selecting non-toxic materials and ensuring proper air filtration.
To encourage creative and innovative design solutions that go beyond the standard sustainability practices.
-
- Implementing unique and groundbreaking design strategies that contribute to sustainability.
-
- Demonstrating new approaches to achieving high levels of energy, water, and material efficiency.
-
- Showcasing innovative uses of technology, materials, or design techniques that can be adopted as best practices.
-
- Providing educational features within the space that inform occupants about the sustainability strategies used.
LEED for Commercial Interiors
LEED for Commercial Interiors (LEED-CI) provides a framework for designing and creating interior spaces that are healthy, energy-efficient, and environmentally sustainable. The program is part of the broader LEED rating systems developed by the U.S. Green Building Council (USGBC), but it can be applied globally, including in India. LEED-CI evaluates projects based on various criteria, categorized into several key areas:
To encourage site selection and design that reduces environmental impacts.
-
- Selection of sites that have access to public transportation, reducing reliance on personal vehicles.
-
- Incorporating features that minimize the heat island effect and manage stormwater effectively.
-
- Promoting connectivity with surrounding communities and encouraging walkability.
To reduce water use through efficient design and technologies.
-
- Installing water-saving fixtures, such as low-flow faucets and dual-flush toilets.
-
- Implementing water reuse strategies, like greywater recycling, to reduce potable water demand.
-
- Encouraging the use of drought-resistant plants in interior landscapes to minimize irrigation needs.
To optimize energy performance and promote the use of renewable energy.
-
- Using energy-efficient lighting, HVAC systems, and appliances to reduce energy consumption.
-
- Incorporating advanced controls and sensors to optimize energy use based on occupancy.
-
- Encouraging the use of renewable energy sources, such as on-site solar panels or purchasing green power.
-
- Implementing commissioning processes to ensure that building systems perform as intended.
To promote the use of sustainable materials and reduce waste.
-
- Selecting materials with recycled content, regional materials, and rapidly renewable resources.
-
- Prioritizing low-emission materials to improve indoor air quality.
-
- Implementing waste management strategies that reduce, reuse, and recycle construction and demolition waste.
-
- Encouraging the reuse of existing materials and furniture to minimize the environmental footprint.
To create a healthy and comfortable indoor environment.
-
- Ensuring adequate ventilation to improve indoor air quality.
-
- Maximizing natural daylight and providing views to the outdoors, enhancing occupant well-being.
-
- Implementing acoustic design strategies to reduce noise and enhance occupant comfort.
-
- Controlling indoor pollutants by using low-VOC (Volatile Organic Compound) materials and ensuring proper air filtration.
To recognize and encourage innovative strategies that enhance sustainability.
-
- Developing new and unique approaches to sustainability that go beyond the standard LEED criteria.
-
- Incorporating features that educate occupants about the green strategies used in the design.
-
- Earning additional points for exceptional performance in any of the LEED categories.
To address regional environmental priorities specific to the project’s location.
- In India, projects may focus on regional challenges such as water scarcity, energy efficiency, or air quality.
- LEED-CI allows projects to earn additional points by addressing these region-specific priorities.
GRIHA Interiors
GRIHA v. 2019 is divided into ten environmental sections, which are further split into 29 criteria, covering all the requisite parameters required to be addressed while making a ‘green building’. An additional section on ‘innovation’ is a part of the rating system that rewards the project team for walking an extra mile to achieve environmental and social sustainabilit. GRIHA Interiors is part of the larger GRIHA framework, which is India’s own green building rating system. GRIHA Interiors is tailored for non-residential interior spaces like offices, retail spaces, hotels, and institutional buildings.
