Introduction to GRIHA
Unlock Audio Lesson
Welcome, students! Today we will discuss GRIHA, which stands for Green Rating for Integrated Habitat Assessment. It's India’s green building certification system focused on sustainability. Can someone tell me what sustainability means?
Sustainability means meeting our needs without compromising future generations' ability to meet theirs.
Exactly! GRIHA aims to assess buildings based on their environmental impacts throughout their lifecycle. Remember the acronym GRIHA; it can be thought of as a 'Guide to Responsible and Innovative Habitat Assessment.'
So, what stages are involved in this assessment?
Great question! GRIHA evaluates buildings in three stages: pre-construction, construction, and operation. Let’s look at each stage more closely.
Pre-construction Stage
Unlock Audio Lesson
The first stage, pre-construction, focuses on planning factors like proximity to public transport and natural site conditions. Why do these elements matter?
They help in reducing the energy needed for transportation and promote better ecological integration.
Exactly! By considering these factors, GRIHA encourages smarter, more sustainable designs right from the conceptual phase.
Are these criteria also assessed during the construction phase?
Yes! The assessment continues into the construction phase, focusing on resource conservation and efficiency.
Building Operations

The final stage is the operation and maintenance of the building. What do you think this involves?
Monitoring energy use and ensuring the well-being of the occupants, right?
Correct! This is vital to assess the building's ongoing environmental impact and its contribution to sustainability. Remember, occupants' health and resource efficiency are key! Can anyone name some parameters GRIHA assesses?
Things like water management, energy efficiency, and waste management!
Well said! All these aspects play a crucial role in achieving GRIHA’s objectives.
GRIHA Points System
Unlock Audio Lesson
Let’s talk about how buildings earn points in GRIHA. How many total points can a project achieve?
So, I've read it can go up to 100+5 points!
Exactly! These points come from assessing various sustainability parameters across the three assessment stages we've discussed. A thorough understanding of these criteria is essential.
What happens if a building doesn’t meet the criteria?
Good question! If it doesn't meet the minimum requirements, it won't receive certification. This reinforces the importance of integrating sustainability into all phases.
Comparing GRIHA and LEED
Unlock Audio Lesson
Now, let’s draw some comparisons between GRIHA and LEED. What are the major differences?
I know GRIHA has a stronger focus on socio-economic aspects, particularly regarding construction workers.
Correct! It emphasizes local contexts and labor welfare, while LEED covers a more balanced approach across all sustainability pillars. Any other differences?
LEED has dedicated credits for regional priorities. Does GRIHA include that as well?
Yes, but GRIHA is more focused on understanding local environment and community needs in its assessments.

Quick Overview
Standard
The GRIHA rating system, developed by TERI and the Government of India, focuses on an integrated approach to sustainability in buildings. It evaluates factors from site planning to building operations to promote resource efficiency and occupant health, assigning significant points across various assessment categories.
Detailed
GRIHA - Green Rating for Integrated Habitat Assessment
GRIHA represents India's own initiative for promoting sustainable building practices, developed by the The Energy and Resources Institute (TERI) and the Ministry of New and Renewable Energy. Its comprehensive assessment framework operates across three stages:
1. Pre-construction Stage: Evaluates factors such as location, soil types, and natural features.
2. Building Planning and Construction Stages: Focuses on resource conservation, efficiency, and occupant well-being.
3. Building Operation and Maintenance: Centers around ongoing monitoring, health considerations, and environmental impacts.
GRIHA assesses buildings on 11 parameters with 30 criteria that sum to 100+5 maximum points, highlighting its emphasis on sustainability in housing development.

GRIHA introduces a comprehensive approach of assessing 11 Parameters with 30 criteria accumulating to 100+5 maximum points (refer Fig. 6), across three stages:
Detailed Explanation
GRIHA, which stands for Green Rating for Integrated Habitat Assessment, provides a framework to evaluate buildings based on various sustainability aspects. It comprises 11 parameters and 30 specific criteria that can earn buildings a total of over 100 points. Understanding this rating system is vital for builders and architects aiming to enhance sustainability in their projects.
Examples & Analogies
Think of GRIHA as a report card for buildings, where instead of just grades for subjects, it evaluates multiple aspects of eco-friendliness and resource management, similar to how a student might be graded on various skills in school.
Pre-construction Stage

- 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.
Detailed Explanation
The pre-construction stage is essential for ensuring that the location and planning of a building meet environmental and community needs. Factors like accessibility to public transport reduce reliance on cars, and understanding local flora and fauna helps protect biodiversity. These considerations set the groundwork for sustainable building practices.
Examples & Analogies
Imagine deciding on a location for a community garden. You would want it to be close to where people live (like public transport for a building) and take into account the soil quality (like soil type) to ensure that the plants grow well.
Building Planning and Construction Stages

- 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.
Detailed Explanation
In the building planning and construction phases, the emphasis is on utilizing resources wisely to minimize waste and ensure comfort for inhabitants. This means using materials efficiently, recycling wherever possible, and making choices that enhance the well-being of future occupants, such as ensuring good air quality and natural lighting.
Examples & Analogies
Consider how a chef prepares a meal. They carefully choose ingredients to ensure they use what they have efficiently, avoid waste, and enhance the health of those who will eat the meal, just as builders aim to create a healthy environment for their occupants.
Building Operation and Maintenance Stage

- 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 operation and maintenance stage is crucial to ensure that the building continues to function efficiently over its lifespan. Monitoring energy use helps identify areas where improvements can be made, while ongoing maintenance ensures that health standards for occupants are upheld. This stage emphasizes continual care to minimize environmental impacts.
Examples & Analogies
Just like getting your car regularly serviced helps it run smoothly and efficiently, the operation and maintenance of a building ensure it continues to be a healthy and efficient environment for its occupants.
