TL;DR
- IGBC certification is a green-building rating from the Indian Green Building Council, part of the Confederation of Indian Industry (CII), scored at four levels: Certified, Silver, Gold and Platinum.
- The rent premium on green offices in India pools in the scarce, high-quality Grade A stock where certification concentrates. That is where the 6% rise to ₹92 per sq ft per month in 2025 landed.
- City vacancy tracks it: in calendar year 2025, Chennai (8.8%) and Bengaluru (12%) ran tight and led rent growth, while Hyderabad, at 26.3%, moved only modestly.
- The demand behind those rents increasingly answers to corporate environmental, social and governance (ESG) reporting: Global Capability Centres (GCCs) took close to 40% of 2025 leasing and increasingly seek green-certified space.
- Lower energy and water use offset the higher rent for occupiers; for owners, certification holds rent through a supply wave and fits the institutional-grade box that investors screen for.
Introduction
A green rating on an office building in India was, for most of the past decade, treated as a compliance line, something to satisfy a policy and move past. What has changed is that the largest occupiers now screen for it before they will shortlist a building at all, and developers plan for it before they break ground.
In our leasing mandates, occupiers rule out uncertified buildings early, before rent is even on the table. So the value of a rating is often the shortlist it keeps a building on, more than any single rent figure it might add. Miss that filter and the building rarely reaches the tenants paying the top of the band.
That shift raises a practical question for anyone signing or building an office: does certification actually show up in the rent, and is it worth paying for? The market quotes green rent premiums freely, while the data that would prove one is thin.
Grade A leasing, by contrast, hit a record in 2025 and held close to it into 2026. The premium is real. The question is what the rating is actually pricing.
What IGBC certification rates, and how a building earns it
A rating only stands in for quality if it measures something real. IGBC certification measures the things that decide how a building runs: its energy and water use, its materials, and the quality of the air, light and site.
The Indian Green Building Council, part of the Confederation of Indian Industry (CII), has run it since 2001. It can certify a new office at the design stage, or an existing one on its operations.
It matters because it turns a vague sustainability claim into a graded, third-party-verified standard that a lease negotiation can reference.
So large occupiers now write it into their site requirements.
The four rating levels, and the certification process
Not every certified building carries the same marker, and the level is what an occupier is really reading. IGBC awards points and assigns one of four levels as the score rises: Certified, Silver,Gold and Platinum, with Platinum the highest.
A developer usually pre-certifies at the design stage, which lets it market the target rating while the building leases. Final certification follows once the building is complete and verified.
| Level | Points (out of 100) | What it recognises |
|---|---|---|
| Certified | 50-59 | Best practices |
| Silver | 60-69 | Outstanding performance |
| Gold | 70-79 | National excellence |
| Platinum | 80-100 | Global leadership |
A higher level signals deeper resource savings, and concentrates in newer, premium Grade A assets.
Designing a Platinum building costs far less than retrofitting one, so the top ratings cluster in the new stock that already commands the strongest rents.
IGBC, LEED and GRIHA
A top rating sits in the same premium stock whichever of the three main green-building systems awards it, so the system a building carries barely moves the rent. Occupiers weigh that choice mainly when they standardise a portfolio.
IGBC is the India-origin framework, calibrated to local codes and cheaper to administer, so most domestic developers use it. LEED, run by the US Green Building Council, is the global benchmark some multinationals default to. GRIHA is the government-endorsed national rating. All three certify the same thing: a measurably lower-resource, higher-quality building.
Where the rent premium actually comes from
Single-figure premium claims circulate widely for green offices in India. They rest on unverifiable samples, crediting the certificate for a gap that quality, location and age largely explain.
The Anarock record points the other way. Where premium stock is scarce, rent climbs, and that is where certification clusters.
What the rent record shows
The rent record supports that reading. Grade A rents have climbed steadily, pooling where quality space is scarce. The pan-India average rose 6% to ₹92 per sq ft per month in 2025, up from ₹87, and is nearly 22% higher than in 2021, per Workplaces 2025.
The climb has not stalled: by H1 2026 the average reached ₹96, 9% above the ₹88 of H1 2025. The report ties this appreciation to a scarce supply of premium Grade A offices meeting sustained demand.
The nature of new supply ties that quality to certification. Workplaces 2025 describes a decisive shift toward high-quality, ESG-driven assets, with leading developments building in smart energy management and recycled materials.
Certification is the external proof of those features, and the buildings that carry it typically sit at the top of the rent band. On the evidence Anarock can stand behind, certification does not add a fixed rupee amount an owner could bank on regardless of the building around it.
Rents and vacancy across the top cities
City vacancy reads that scarcity directly. Where it is low, quality stock is tight and rent rises;
where supply has run ahead of tenants, pricing softens even for good buildings.
Certification concentrates in the tight, quality-led markets, which is why it correlates with stronger rent rather than causing it on its own.
| City | Grade A vacancy (2025) | Grade A rent read (2025) |
|---|---|---|
| Chennai | 8.8% (most stable) | +32% since 2021 (fastest of the seven) |
| Pune | 11.9% | Rising, absorption-led |
| Bengaluru | 12% | ₹102 per sq ft per month; +31% since 2021 |
| MMR (Mumbai Metropolitan Region) | 14.7% | ₹148 per sq ft per month (costliest market) |
| Pan-India (top 7 cities) | 16.1% | ₹92 per sq ft per month; +6% in the year, +22% since 2021 |
| NCR (National Capital Region) | 21.7% | Modest growth |
| Hyderabad | 26.3% (highest) | Modest, supply-heavy |
The pattern is consistent: where the high-quality stock that certification marks is scarce, rent rises; where uncertified supply floods a corridor, as in Hyderabad, it does not. A building priced on the national average, not its own micro-market, misreads both ends of that range.
What keeps the tight markets tight is who leases them, and one occupier group drives that demand more than any other.
Why the biggest occupiers now ask for certification
The demand that sets rent at the top of the band increasingly answers to a parent-group ESG budget. Global corporate occupiers now report Scope 3 emissions, which include leased real estate. A certified office is the straightforward way to hold an occupancy inside that budget.
Workplaces 2025 records this for the largest office market in the country: GCCs in Bengaluru increasingly seek premium, green-certified space.
The weight behind that preference is what moves rents. GCCs are the single largest occupier group. In 2025 they leased a little over 32.5 mn sq ft across the top seven cities. That was a little over 40% of the 80.5 mn sq ft taken in those markets.
The largest source of rent-setting demand is therefore ESG-mandated and quality-first, and certified space is where it lands.
But what it pays turns on more than the headline rent.
What certification does to total occupancy cost
For occupiers, a higher headline rent is only one line in the cost of holding a building.
The other is what it costs to run, and that is where certification pays back.
The Indian Green Building Council states green buildings can cut energy use by 20-30% and water use by 30-50% against a conventional baseline. A certified building can therefore cost less to occupy in total than a conventional one that rents for less.
That trade is a modest rent premium against a larger utility and compliance saving. It is why global occupiers treat green certification as cost-neutral, even cost-saving, rather than a premium indulgence. An occupier should rank certification among the other factors to weigh when leasing office space and price it into total occupancy cost.
What the green premium means for developers and owners
A developer or owner reads certification the opposite way to a tenant counting occupancy cost. For them it is a pricing and liquidity tool. It lets an owner hold rent through a supply wave, pre-lease to credit occupiers before completion, and exit into institutional capital that now screens for sustainability.
Workplaces 2025 expects demand to keep running ahead of the roughly 155 mn sq ft of supply planned over two years. That points to further rent appreciation in well-specified new assets.
The same quality that earns the rent also shows up again at the point of sale.
Certified, income-yielding offices fit the institutional-grade box that real estate investment trusts (REITs) and cross-border funds underwrite, that is, assess and price for purchase.
Only about 20% of institutional-grade real estate in India sits inside a listed REIT today, a share projected to reach 25-30% by 2030. Stabilised assets, fully let and well-specified, are the ones that pool is most likely to absorb, and certification is the marker those buyers screen on.
Building it in from the start rather than retrofitting later is the cheapest way to capture this, per Anarock on why sustainability must be embedded from day one and how project management is driving ESG in real estate.
Key takeaways
- Green-certified offices in India earn higher rent as a quality premium, not a certificate surcharge: certification concentrates in the newest Grade A stock, which commands the top of the local band on its own merits.
- IGBC grades a building Certified, Silver, Gold or Platinum, and the top levels are locked in at the design stage, so they cluster in premium new buildings.
- No reliable single national green-premium figure exists, so market claims that quote one should be treated with caution.
- ESG-mandated demand is the mechanism: GCCs took close to 40% of 2025 leasing and increasingly seek green-certified space.
- Certification is cost-neutral or cost-saving for occupiers and a pricing and liquidity tool for owners, easing an eventual institutional exit.
Where this sits at Anarock
At Anarock, the commercial leasing and advisory practice prices this trade-off on live deals, from certification-led site selection to rent and cost benchmarking against verified market data. The practice is led by its managing director, Peush Jain.
Methodology and coverage. The office figures here cover Grade A stock across the top seven cities in India: Bengaluru, NCR, MMR, Pune, Hyderabad, Chennai and Kolkata. They are calendar-year 2025 readings, with the latest half-year data from H1 2026, drawn from the Anarock research reports cited throughout. Certification detail, including rating levels and stated savings, is from the Indian Green Building Council. No isolated green-versus-non-green rent premium is published in that research, and this piece does not assert one.
Frequently asked questions
What is IGBC certification, and what are the rating levels?
IGBC certification is a green-building rating from the Indian Green Building Council, part of the Confederation of Indian Industry (CII), which has run the green-building movement in India since 2001. A building earns points across energy, water, materials, indoor environment and site. It is rated at one of four levels as the score rises: Certified, Silver, Gold and Platinum, with Platinum the highest. In an office, a higher level generally maps to newer, premium Grade A stock that already sits at the top of its local rent band.
Do IGBC-certified green offices actually earn higher rent in India?
Yes. Certified offices lease at the top of the local band because they sit in the newest, scarcest Grade A stock. Anarock x FICCI Workplaces 2025 shows pan-India Grade A rents up 6% to ₹92 per sq ft per month in 2025 and about 22% since 2021, concentrated in that premium stock. Older uncertified space, meanwhile, discounts to stay full. No Anarock figure isolates a green-only premium, and no reliable single national number for one exists.
How do you get an office IGBC certified, and what does it affect?
A developer usually pre-certifies at the design stage, which allows the target rating to be marketed while the building is still leasing. Final certification follows once the building is complete and verified. An operating building can be certified on its running performance instead. Because the higher levels are largely determined by design decisions, certification is cheapest to achieve when built into the programme from the start rather than retrofitted. IGBC is also generally cheaper to administer than LEED, because it is calibrated to Indian codes.
Is IGBC certification better than LEED for Indian offices?
Neither is strictly better; they suit different occupiers. IGBC is calibrated to Indian climate, materials and codes and is usually cheaper to administer, so most domestic developers choose it. Some global occupiers specify LEED, run by the US Green Building Council, for consistency across a multi-country option. All certify a measurably lower-resource, higher-quality building, which is what drives the rent and demand effect.
Does IGBC certification reduce a tenant's operating cost?
Yes, and this offsets the rent premium. The Indian Green Building Council states green buildings can cut energy use by 20-30% and water use by 30-50% against a conventional baseline. Lower utility and compliance cost reduces the total occupancy cost. That is why global occupiers treat sustainable office space in India as cost-neutral or cost-saving, rather than a premium indulgence.
Why do GCCs prefer green-certified office space?
Global Capability Centres report into parent-group ESG and Scope 3 emissions targets, which include leased real estate. A certified building keeps that occupancy within the ESG budget. GCCs took close to 40% of the 80.5 mn sq ft leased across the top seven cities in 2025, and Workplaces 2025 records GCCs in Bengaluru as increasingly seeking green-certified space. This ESG-mandated demand is a major force behind demand for certified assets.
Do REITs and institutional buyers value green certification?
Yes. Certified, income-yielding offices fit the institutional-grade box that real estate investment trusts (REITs) and cross-border funds underwrite. Only about 20% of institutional-grade real estate in India sits inside a listed REIT today, a share projected to reach 25-30% by 2030. As that pool grows, the certified, stabilised assets are the ones it can absorb. The green premium then recurs at sale as well as in rent.
