GRIHA Rating

Introduction

 
 

The GRIHA stands for Green Rating for Integrated Habitat Assessment. It was developed as a tool to facilitate design, construction, operation of a green building, and, in turn measure “greenness” of a building as per the applicable climate zone.

The GRIHA rating system covers different sustainability measures that shall be implemented during design, construction, post-construction and during-operations measures. As a combination of these measures, a built-environment shall achieve the rating adhering to the compliance measures.

Intent

 
 

India is a land of diverse climatic conditions and varied construction methodologies suited to its unique environmental contexts. To promote green buildings across the country, it was essential to formulate guidelines that accounted for these regional differences. The GRIHA rating system was thus developed to facilitate the construction of sustainable built environment that aligns with local environmental variables and site-specific characteristics.

Indigenous rating system

The system acknowledges the diverse climatic conditions of the country which become the underlying factor for the formulation of GRIHA rating. The rating system aims at providing inherent solutions for thermal comfort within each region.

Adoption of holistic approach towards sustainability

The rating system was developed with the intent to promote sustainability by not just underlining the environmental aspects but also focusing on the social and economic aspects as well.

Process driven and performance oriented

Every stage of construction, starting from design conception to execution, is vital to achieve sustainability. GRIHA takes into account all the stages, including design, procurement, and implementation to avoid disruption to the ecological system and construct high-performing sustainable structures.

Integrated team approach

With the aim to interact with the project team and guide them through the rating process, an orientation workshop is conducted by GRIHA Council where representatives from different divisions handling the project are present to understand their role in making the project GRIHA compliant.

Benefits/Advantages of adopting GRIHA Rating

Reduced Energy Consumption

Encourages passive design strategies, energy-efficient systems, and renewable energy integration to reduce operational energy use.

💧

Water Conservation

Promotes rainwater harvesting, wastewater treatment, and water-efficient fixtures to enhance self-reliance for water consumption.

♻️

Waste Reduction

Incorporates solid waste management, construction waste minimization, and waste reuse and recycling to convert waste to resource.

🌍

Lower Carbon Footprint

Encourages the use of low-embodied energy materials and enhances the operational efficiency to reduce GHG emissions.

💰

Lower Operating Costs

Reduced energy and water use directly translating into long-term savings for occupants and owners.

📈

Enhanced Asset Value

Sustainable buildings offer higher marketability and occupancy rates.

🏛️

Eligibility for Incentives

Governments offer fast-track approvals, extra FAR, and tax rebates for GRIHA-rated projects.

REQUIRED CRITERION

All new construction projects with built-up area more than 2,500 sq.m are eligible for rating.

The following areas are excluded from the built-up area:

  • Parking area (Stilt/Basement)
  • Non-habitable basement spaces
  • Typical buildings: These are with same orientation, height, floor plan, plinth level and are constructed within a defined site boundary.
  • Service rooms: These are spaces that are dedicated to building services, such as electrical room, server room, meter room, etc., with no occupancy.
