What Are IGBC and GRIHA Ratings? And Do They Increase Property Value?

When people buy a home, they usually look at location, carpet area, amenities, builder reputation, price, possession timeline and connectivity. But today, one more factor is slowly becoming important: how sustainable the building is.

This is where green building certifications like IGBC and GRIHA come in.

For buyers comparing residential projects in Mumbai, these ratings can be useful because they show whether a project has been planned with better energy use, water savings, waste management, ventilation, natural light and long-term comfort in mind. But do these ratings directly increase property value? The answer is: they can help, but they are not the only factor.

Let us understand this in a simple way.

What Is IGBC Rating?

IGBC stands for Indian Green Building Council. It offers green building rating systems for different types of buildings, including homes, residential societies, commercial buildings, townships and more. IGBC says its rating systems bring together sustainable practices and solutions to reduce the environmental impact of buildings.

For residential buyers, the most relevant one is IGBC Green Homes. According to IGBC, this rating programme is designed for the residential sector and focuses on site resources, water conservation, energy efficiency, household waste handling, material use and healthier homes.

In simple words, an IGBC-rated home is assessed on how responsibly it uses resources and how comfortable it can be for residents over time.

What Is GRIHA Rating?

GRIHA stands for Green Rating for Integrated Habitat Assessment. It is India's national rating system for green buildings, developed by TERI and adopted by the Government of India in 2007.

GRIHA ratings evaluate buildings based on established benchmarks and thresholds. These systems are used for multiple project types, including residential, commercial, institutional and hospitality projects.

For a homebuyer, this means GRIHA is a structured way of checking whether a building has been designed with sustainability, resource efficiency and environmental responsibility in mind.

What Do These Ratings Check?

While IGBC and GRIHA have their own systems, they usually look at similar broad areas:

• Energy efficiency
• Water conservation
• Waste management
• Use of sustainable materials
• Indoor air quality
• Natural light and ventilation
• Site planning
• Landscape and open spaces
• Long-term environmental impact

IGBC Green Homes, for example, lists site selection and planning, water conservation, energy efficiency, materials and resources, indoor environmental quality, and innovation as key categories.

For buyers, these things matter because they affect daily living. A home with better ventilation, good daylight, efficient water systems and lower energy use can feel more comfortable and may be easier to maintain over the years.

Do IGBC and GRIHA Ratings Increase Property Value?

Green certifications can support property value, but they do not work like a magic price booster.

A green rating can improve the perception of a project because it signals better planning. It can also make the property more attractive to future buyers or tenants who care about lower running costs, responsible living and better building quality.

IGBC also mentions that green homes can offer tangible benefits like lower water and operating energy costs, along with intangible benefits like better air quality, daylight, wellbeing and improved marketability.

So yes, a green-rated building may have stronger long-term appeal. But value still depends on other major factors such as location, developer track record, construction quality, RERA status, carpet area, amenities, connectivity and demand in that micro-market.

Why This Matters More in Mumbai

Mumbai is a dense city. Every square foot matters. Buyers are not just looking for bigger homes anymore; they are looking for smarter homes.

This is why sustainability matters when evaluating residential projects in Mumbai. A building that saves water, manages waste better, uses energy efficiently and offers healthier common spaces can become more relevant over time.

For example, buyers comparing residential projects in Goregaon west, residential projects in Chembur east, residential projects in Malad west or residential projects in Borivali east may not look only at price. They may also ask:

Is the building future-ready?
Will maintenance be efficient?
Will the home get good light and ventilation?
Are the open spaces usable?
Is the developer thinking beyond just construction?

These are the questions that separate ordinary projects from well-planned ones.

What Should Buyers Ask Before Trusting a Green Claim?

Not every project that uses words like "green," "eco," "nature-inspired" or "sustainable" is certified. Buyers should ask clear questions before making a decision.

Ask the developer:

• Is the project IGBC or GRIHA certified?
• If yes, what is the rating level?
• Is it pre-certified or finally certified?
• Which green features are included?
• Are water-saving systems part of the project?
• Is there rainwater harvesting or wastewater treatment?
• How is waste managed?
• What features reduce energy consumption?
• Will these features affect maintenance costs?

This is especially important when comparing real estate builders. Instead of only searching for real estate builders in Mumbai, top real estate builders in Mumbai or best builders in Mumbai, buyers should also check what kind of planning and long-term value the developer brings.

How Chandak Group Projects Fit Into This Conversation

Chandak Group's larger brand promise is built around "Promises Made. Promises Kept." The brand highlights 40+ years of legacy, 12 million+ sq. ft. developed, 45+ completed projects and 12,000+ happy families.

For buyers, this matters because sustainability should not be seen separately from trust. A green feature has value only when it is planned well, delivered properly and maintained over time.

Projects such as 34 park estate in Goregaon West, Chandak Greenairy in Borivali East and Chandak Sarvam in Andheri East show how modern buyers are looking at homes across different Mumbai micro-markets. Chandak's portfolio also includes 34 Park Estate, GreenAiry, Treesourus, Vansham, and Sarvam across Mumbai.

A family looking for a 2 BHK in Goregaon West at 34 park estate may have different needs from someone looking for a luxurious 2bhk in Borivali at Chandak Greenairy or a 3 bedroom apartment in Andheri East around Chandak Sarvam. But in every case, the larger question remains the same - will this home stay comfortable, efficient and relevant in the future?
