Most homes you see on sale in Bengaluru are still being built. So if they carry a green label, it is usually a pre-certification. That is normal. The useful thing is to know what it covers, and what still has to happen.
What was checked
At pre-certification, the rating body looked at the design: drawings, plans and the list of green features the builder intends to include.
What still needs checking
Once the building is complete, the builder can apply for final certification. Then the rating body checks that the promised features were actually built.
What sits in between
Construction takes time. In that gap, designs can be changed, products swapped and features dropped. Usually for ordinary reasons like cost or supply. That is why the final check matters.
Why a final certificate may never arrive
- The builder chooses not to apply.
- Some features changed, and the building no longer scores the same.
- Paperwork is delayed after handover.
None of these is a disaster for you as a home owner, but it does mean the label on the brochure was only ever a design score.
Three quick questions
- "Is this design-stage or final?"
- "Do you plan to apply for final certification, and roughly when?"
- "Which green features are in my agreement?"
The third is the one that protects you most. Features written into your agreement are a commitment. Features only on a brochure are not.
What to check at handover
Walk through the list of green features with the builder. Is the rainwater harvesting in place? Is the sewage treatment plant running? Are the water-saving fittings the ones promised? Note anything missing before you sign the handover papers.
The journey of a green label, step by step
- Registration. The builder registers the project with the rating body.
- Pre-certification. The design is assessed and given a provisional level.
- Construction. The building is built. This is where changes can happen.
- Completion. The builder collects proof that features were installed: bills, photos, test reports.
- Final assessment. The rating body reviews that proof and may visit.
- Final certificate. Issued at a level that may match, beat or fall short of the provisional one.
You buy somewhere between step 2 and step 4, so you are relying on the first half of this list. That is fine, as long as you know it.
A worked example: one feature, checked twice
This is illustrative arithmetic, based on simple assumptions.
Say a design includes rainwater harvesting from a roof of 500 square metres. Assume 900 mm of rain a year (check the IMD normal for your area) and that 80% of it can be collected. The water collected in a year would be:
500 m² × 0.9 m × 0.8 = 360 cubic metres, which is 3,60,000 litres.
That number is what was on paper at pre-certification. At handover, ask to see the pits or tanks, and how roof water reaches them. If the downpipes have been routed to a storm drain instead, the 3.6 lakh litres exist only in the design.
Reading your agreement for green promises
Look at the schedule of specifications attached to your agreement for sale. Under section 14 of the Real Estate (Regulation and Development) Act, 2016, a promoter must build according to the sanctioned plans and the specifications agreed with you, and cannot make certain changes without the buyer's consent. So a green feature written into that schedule has real weight. A feature mentioned only in an advertisement is weaker, though section 12 of the same Act does give you a remedy if an advertisement or brochure is false and you suffer loss.
How long the gap can be
A building usually takes a few years from launch to handover. Your registered agreement and the project's RERA page will show the promised completion date. The final green assessment, if the builder applies, comes after completion. So the label you saw at booking may not be confirmed until some time after you move in. Plan for that and do not treat the final certificate as part of your handover.
Questions to ask at each stage
- At booking: "Please share the pre-certification letter and the feature list it was based on."
- During construction: "Have any green features changed since pre-certification? If so, which, and why?"
- Near completion: "Will you apply for final certification? Who will be my contact for it?"
- After handover: "Who in the owners' association will receive the certificate, and the operation manuals for shared systems?"
What the owners' association inherits
Once residents take over the building, the shared green systems become theirs to run. That means the sewage treatment plant, the rainwater pits, pumps, solar equipment and common lighting. Ask the builder to hand over manuals, warranties and maintenance contracts. A well-run system keeps working; a neglected one quietly stops, and the brochure promise ends there.
Common mistakes
- Treating pre-certification as a final result. It is a score for the design.
- Not asking for the feature list in writing. Memory fades over a construction period.
- Signing handover papers in a hurry. Once signed, raising missing features becomes harder.
- Forgetting the running costs. A sewage treatment plant and pumps need power and staff, paid from maintenance.
- Losing sight of the basics. Title, approvals and your EMI still come first.
Keep the paper trail
Store the pre-certification letter, the feature list, your agreement's specification schedule and every written answer from the builder in one folder. If a promised feature is missing at handover, these papers are what you will show, first to the builder and, if needed, to the Karnataka RERA authority. Without them, a complaint becomes your word against a brochure.
Handover checklist for green features
- Rainwater harvesting pits or tanks in place and connected
- Sewage treatment plant installed and running, with an operator
- Water-saving fittings match the specified flow rates
- Solar panels or solar water heating, if promised, installed and working
- Common-area lighting as specified
- Any missing item written on the handover sheet, signed by both sides
