Introduction to GRIHA
Unlock Audio Lesson
Today, we are going to discuss GRIHA, which stands for Green Rating for Integrated Habitat Assessment. GRIHA is India’s own national green building rating system. Can anyone tell me why having a local rating system is important?
It helps cater to the unique environmental and social contexts of India.
Exactly! GRIHA focuses on the specific needs and challenges of our environment. It assesses buildings on various parameters, such as resource conservation and optimizing energy use. Let’s delve into the stages it evaluates.
What are these stages?
Great question! GRIHA evaluates buildings through three main stages: the pre-construction stage, the construction stage, and the operation and maintenance stage. Each of these stages has specific criteria to fulfill.
Can you give an example of what’s evaluated in the pre-construction stage?
Sure! In the pre-construction phase, GRIHA looks at factors such as the proximity to public transport and the type of soil. These factors can significantly influence a building's environmental impact.
I see how that could affect sustainability! What about the points system?
GRIHA has a total of 100+5 maximum points available, reflecting its comprehensive approach to sustainability. Well done, everyone! Let's summarize: GRIHA is a national rating system important for addressing local environmental needs, focusing on various stages from planning to operation.
Comparative Analysis of GRIHA and LEED
Unlock Audio Lesson
In our next session, let's compare GRIHA with LEED. What are some key features you think GRIHA might emphasize more than LEED?
Perhaps the socio-economic factors for laborers?
Exactly! GRIHA includes a dedicated assessment for socio-economic aspects related to laborers and awareness on environmental issues. Can anyone think of why this would be important?
It ensures laborers are considered in sustainable practices!
Absolutely! In terms of points allocation, GRIHA emphasizes environmental and economic factors profoundly, while LEED seems to have a more balanced approach across all three pillars of sustainability: environmental, economic, and social.
It sounds like GRIHA might be more tailored to Indian realities.
Exactly! The local context plays a significant role. Let's recap what we've discussed: GRIHA's focus on socio-economic factors makes it unique in comparison to LEED.
Energy Performance Index (EPI)
Unlock Audio Lesson
Now, let's shift gears and talk about the Energy Performance Index, or EPI. Who can share what they understand this index measures?
Does it measure how efficiently buildings use energy?
Correct! The EPI assesses a building's energy consumption in relation to its area and promotes actions for energy efficiency in both new and existing structures. Why do you think this is vital for India?
Because we have a growing demand for energy with so many new buildings!
Right! By targeting reductions in energy consumption, the EPI helps build a more sustainable future. Can anyone think of a way that this might tie into GRIHA?
Both systems aim to enhance sustainability in our buildings!
That’s a fantastic connection! To summarize, the EPI is crucial for making our buildings more energy-efficient, contributing positively to our environmental goals.

Quick Overview
Standard
The section explores India's two main green building certification systems, GRIHA (Green Rating for Integrated Habitat Assessment) and the Energy Performance Index (EPI) developed by the Bureau of Energy Efficiency. It outlines the parameters and criteria for GRIHA and compares its focus on environmental, economic, and social aspects against the more balanced LEED certification.
Detailed
Overview of Green Building Certifications in India
India recognizes several green building certifications, among which GRIHA and the Energy Performance Index (EPI) by the Bureau of Energy Efficiency (BEE) are the most significant apart from LEED.
GRIHA Certification
GRIHA, or the Green Rating for Integrated Habitat Assessment, is a national rating system developed by TERI in collaboration with the Ministry of New and Renewable Energy. It assesses buildings based on various sustainability criteria across three main stages:
1. Pre-construction Stage: Evaluates on-site and off-site factors, including soil type and proximity to public transport before construction occurs.
2. Building Planning and Construction Stage: Focuses on optimizing resource usage and ensuring the well-being of occupants.
3. Operation and Maintenance Stage: Involves monitoring energy consumption and maintaining occupant health.
With a total of 100+5 points available, GRIHA emphasizes the interconnection of environmental sustainability, economic viability, and social responsibility. A comparative analysis with LEED shows that while GRIHA has a strong focus on environmental and economic aspects, it also includes socio-economic factors affecting laborers more explicitly than LEED does.
Energy Performance Index (EPI)
The Energy Performance Index assesses buildings based on their energy consumption relative to their area, effectively guiding improvements in energy efficiency in India's diverse construction sector. This approach facilitates energy benchmarking and targets reductions in energy consumption for existing buildings.
Together, these certification systems represent a critical advancement in promoting sustainable architecture and urban development in India, aligning with global sustainability efforts.

Apart from LEED, the other 2 main green building certification systems in India, are; GRIHA (Green Rating for Integrated Habitat Assessment), India’s own rating system jointly developed by TERI and the Ministry of New and Renewable Energy, Government of India, and BEE (Bureau of Energy Efficiency) developed its own rating system for the buildings and the Energy Performance Index (EPI).
Detailed Explanation
In India, while the LEED certification is well-known, there are two other significant green building certifications: GRIHA and BEE. GRIHA, or Green Rating for Integrated Habitat Assessment, is developed in collaboration between TERI (The Energy and Resources Institute) and the Government of India. This certification assesses the environmental performance of buildings using a comprehensive set of criteria. Similarly, the Bureau of Energy Efficiency (BEE) has its own rating system known as the Energy Performance Index (EPI), which focuses on energy efficiency in buildings.
Examples & Analogies
Consider the way schools have multiple accreditation bodies. Just like how an educational institution might seek recognition from various educational boards to validate and improve its standards, buildings in India can pursue multiple certifications to showcase their commitment to sustainability and efficient use of resources.

GRIHA introduces a comprehensive approach of assessing 11 Parameters with 30 criteria accumulating to 100+5 maximum points (refer Fig. 6), across three stages: 1. Pre-construction stage: This stage addresses both on-site and off-site factors, such as the proximity to public transportation, soil type, land characteristics, location, existing flora and fauna, and natural landscape features before construction begins. 2. Building planning and construction stages: This stage focuses on resource conservation, reducing resource demand, optimizing resource utilization efficiency, promoting resource recovery and reuse, and ensuring occupant health and well-being. 3. Building operation and maintenance stage: This stage encompasses the operation and maintenance, monitoring and recording energy consumption, ensuring occupant health and well-being, and addressing factors that impact the local and global environment.
Detailed Explanation
The GRIHA certification system evaluates buildings based on 11 parameters with 30 distinct criteria, allowing for a maximum of 105 points. The assessment occurs in three key phases: The pre-construction stage focuses on the environmental context of the building, examining things like accessibility to public transportation and the natural landscape. During the construction phase, emphasis is placed on resource conservation, ensuring that the materials used are efficiently utilized. Finally, the operation and maintenance stage evaluates how the building performs in terms of energy and resource management during its actual use, including occupant health considerations.
Examples & Analogies
Think of GRIHA's three stages similar to a school project. At first, you plan and research (pre-construction), then you gather materials and build (construction), and finally, you present your project and defend your work (operation and maintenance). Each stage is crucial for the overall success of your project.

Ji et al., 2017, conducted a comparative analysis of GRIHA v2015 and LEED v4 for BD + C: New Construction and Major Renovation with respect to the three pillars of Sustainability and reported; GRIHA v2015 has a strong focus on Environmental and Economic aspects, less Social. It has a dedicated section for assessment of socio-economic aspects of the laborers and service professionals, creating awareness on environment and design for diversity in accessibility, missing from LEED.
Detailed Explanation
A study compared GRIHA and LEED in terms of how well they address the three pillars of sustainability: environmental, economic, and social concerns. GRIHA was found to emphasize environmental and economic sustainability but has additional criteria focusing on social sustainability, particularly regarding labor and accessibility. In contrast, LEED tends to balance its focus more evenly across these pillars, including specific credits for regional priorities and social aspects, like open space access.
Examples & Analogies
Imagine a competitive cooking show where one dish is focused mostly on taste (like GRIHA focusing on environment and economy), while the other not only adds flavor but also presents beautifully (like LEED addressing aesthetic and social needs too). Each dish has strengths, but their differences highlight diverse culinary philosophies.
