Green Rating for Integrated Habitat Assessment (GRIHA)

The subtopics of Green Rating for Integrated Habitat Assessment (GRIHA) are:

• Site Planning and Design
• Water Efficiency
• Energy Efficiency
• Materials and Resources
• Indoor Environmental Quality
• Operation and Maintenance
• Innovation and Design Excellence
• Credits and Rating
  Green Rating for Integrated Habitat Assessment (GRIHA) is a green building rating system developed in India. It is a voluntary rating system that encourages sustainable design and construction practices. GRIHA was developed by the Indian Green Building Council (IGBC) in 2007. It is based on the principles of sustainable development and aims to reduce the environmental impact of buildings.

GRIHA is a performance-based rating system. This means that it assesses the performance of a building in terms of its energy efficiency, water efficiency, indoor environmental quality, and other environmental impacts. GRIHA awards points for meeting certain performance criteria. The total number of points awarded determines the building’s GRIHA rating.

There are six major categories in GRIHA:

• Site Planning and Design
• Water Efficiency
• Energy Efficiency
• Materials and Resources
• Indoor Environmental Quality
• Operation and Maintenance

Each category has a set of credits that can be earned. The credits are weighted according to their importance. The more credits a building earns, the higher its GRIHA rating.

GRIHA is a comprehensive rating system that covers all aspects of sustainable building design and construction. It is a valuable tool for developers, architects, and engineers who want to build green buildings in India.

Site Planning and Design

The site planning and design category assesses the impact of a building on its surroundings. It includes credits for factors such as siting, orientation, and landscaping. The goal of this category is to minimize the environmental impact of the building and to create a sustainable built environment.

Water Efficiency

The water efficiency category assesses the use of water in a building. It includes credits for factors such as water harvesting, rainwater harvesting, and water recycling. The goal of this category is to reduce the consumption of water in a building and to conserve water resources.

Energy Efficiency

The energy efficiency category assesses the use of energy in a building. It includes credits for factors such as energy-efficient lighting, energy-efficient appliances, and energy-efficient HVAC systems. The goal of this category is to reduce the consumption of energy in a building and to save energy costs.

Materials and Resources

The materials and resources category assesses the use of materials and resources in a building. It includes credits for factors such as using recycled materials, using local materials, and using sustainable materials. The goal of this category is to reduce the environmental impact of the building and to promote the use of sustainable materials.

Indoor Environmental Quality

The indoor environmental quality category assesses the quality of the air, water, and other environmental factors in a building. It includes credits for factors such as ventilation, air quality, and water quality. The goal of this category is to create a healthy and comfortable indoor environment for occupants.

Operation and Maintenance

The operation and maintenance category assesses the operation and maintenance of a building. It includes credits for factors such as energy management, water management, and waste management. The goal of this category is to ensure that the building is operated and maintained in a sustainable manner.

GRIHA is a valuable tool for developers, architects, and engineers who want to build green buildings in India. It is a comprehensive rating system that covers all aspects of sustainable building design and construction.
