Green Rating for Integrated Habitat Assessment also known as GRIHA was jointly established as an autonomous, not-for-profit organization by The Energy and Resources Institute (TERI) and the Ministry of New and Renewable Energy (MNRE). It provides a clear benchmark for green buildings and sustainable living environments by comprehensively assessing a building's environmental performance over its full life cycle using both quantitative and qualitative criteria. This takes into account the numerous, nationally recognized benchmarks. Buildings that meet these requirements are designated as "green buildings." This article will explain to you about Green Rating for Integrated Habitat Assessment (GRIHA) which will be helpful in preparing the Environment Syllabus for the UPSC Civil Service exam.

GRIHA - Objective & Aim

• The rating system's primary goal is to assist in the design of green buildings and, as a result, in evaluating the 'greenness' of the buildings.
• The rating system aims to achieve efficient resource utilisation, increased resource efficiency, and improved building quality of life.

GRIHA - Basic Features

• This system was created to assist with the "design and evaluation" of structural components (buildings that are still at the inception stages).
• Based on its expected performance from creation through operation over the course of its full life cycle, a building is evaluated.
• The life cycle stages that have been designated for examination are:
• Pre-construction Stage: Intra- and inter-site issues like proximity to public transport, type of soil, kind of land, where the property is located, the flora and fauna on the land before construction activity starts, the natural landscape and land features.
• Building Planning and Construction Stages: Issues of resource conservation and reduction in resource demand, resource utilization efficiency, resource recovery, and reuse, and provisions for occupant health and well-being.
• Land, water, energy, air, and green cover are the main resources that are taken into consideration in this section.
• Building Operation and Maintenance Stage: Issues of operation and maintenance of building systems and processes, monitoring and recording of energy consumption, occupant health, and well-being, and also issues that affect the global and local environment.

GRIHA - Rating Tool

• GRIHA is a rating tool that assists people in assessing the performance of their building against certain nationally acceptable benchmarks. It is appropriate for all types of buildings in the country's various climatic zones.
• Following the adage 'what gets measured, gets managed,' GRIHA attempts to quantify aspects such as energy consumption, waste generation, renewable energy adoption, and so on in order to manage, control, and reduce them to the greatest extent possible.
• It will evaluate a building's environmental performance holistically over its entire life cycle, providing a definitive standard for what constitutes a "green building."
• Based on accepted energy and environmental principles, the rating system will seek to strike a balance between established practises and emerging concepts, both national and international.
• The guidelines/criteria appraisal may be revised every three years to reflect the most recent scientific developments during that time period.

GRIHA - Rating System

• The GRIHA rating system consists of 34 criteria divided into four categories. They are:
  • Site selection and planning
  • Resource conservation and efficient utilisation
  • Building operation and maintenance
  • Innovation points
• Eight of the 34 criteria are required, four are partially required, and the rest are optional. Each criterion is assigned a number of points.
• It means that a project that intends to meet the criterion will be eligible for the points.
• The number of points earned determines the level of certification (one star to five stars). Certification requires a minimum of 50 points.

GRIHA - International Recognition

• The GRIHA rating system is a cutting-edge tool in the hands of the United Nations for the goal of sustainable development on a global scale.
• With the aid of "The Climate Reality Project," this serves as a crucial tool for the adoption of renewable energy in the building industry.
• In this perspective, the "Common Carbon Metric" is regarded as a key tool that aids in the data collecting on global building energy.
• The GRIHA is used as a source of input with the aim of gathering data.

GRIHA - Significance

• Enhances the Design Process: The framework provided by green grading systems, which define "sustainability" and relate project problems and solutions within it, offers standards and measurements that enhance collaboration.
• Provides Economic Benefits: An efficient, long-lasting, and robust project is frequently the consequence of a green rating system.
• Utilizing a sustainability framework can lead to chances for tax benefits, long-term operational cost reductions, and a decrease in waste and energy expenditures.
• Reduces Risk: Green rating systems put an emphasis on the purposes, means, and techniques of a project. Green initiatives are more equipped to lessen the devastating effects of natural disasters.
• Additionally, these projects are better suited to endure fluctuating energy prices and guard against losses due to fire and plumbing damage.
• Adds a Competitive Advantage: Green rating systems push teams to consider the project from fresh perspectives that open up opportunities for cost savings, project life extension, investor attraction, stakeholder and public appeal, community well-being improvement, and many other advantages that boost the owner's competitive edge.
• Increases Accountability: Green rating systems link planning and design to sustainability policies so that the overall project concept is employed throughout.
• Additionally, these rating systems encourage stakeholder involvement and offer benchmarks that aid in tracking the development and maintaining project team focus.
• Improves Quality of Life: A green rating system's sustainable design guidelines help build more resilient and livable communities with less waste, more possibilities to preserve and safeguard natural ecosystems, and citizens who get to breathe cleaner air and drink cleaner water.
• Offers Recognition: Because of the chances for media coverage, press releases, and public relations communications, a project that has a green rating is more visible throughout the community.
  • Additionally, green ratings increase tenant acceptability, owner image, political capital, and the likelihood of receiving other project awards.
  • They also contribute to better tenant acceptance.

GRIHA - Benefits

On a larger scale, this system, as well as the activities and processes that lead up to it, will benefit the community as a whole by improving the environment by lowering GHG (greenhouse gas) emissions, energy consumption, and the strain on natural resources.

• Reduced energy consumption while maintaining comfort levels
• Reduced destruction of natural areas, habitats, and biodiversity, as well as reduced soil loss due to erosion, among other things.
• Air and water pollution reduction (with direct health benefits)
• Water consumption has been reduced
• Reduced waste generation as a result of recycling and reuse
• Pollution loads have been reduced
• Enhanced user productivity
• Image and marketability enhancements

GRIHA - Challenges

• The construction industry in India is extremely decentralized, with organizations and/or individuals cooperating on design, building, equipment provision, installation, and renovation.
• The integrated green design and application process is disabled by the limited interaction across the groups, despite the fact that each group may be somewhat organized.
  • As a result, it is critical to define and quantify sustainable building practises and their benefits.
• Separating the responsibilities of different parties will help to ensure that the building uses the fewest resources possible over its full life cycle and leaves the least possible environmental imprint.
