Oct 2025Precertified; valid 3 years pending final certification

The Indian Green Building Council (IGBC) rates residential projects under its Green Homes Rating System. A precertification is awarded at the design stage, on the basis of the project's documented design intent, and is valid for three years pending six-monthly progress updates through to final certification, which is assessed once the project is built. Vinayak 21 Acres is precertified at the Platinum level — the highest tier — under Registration No. GH250539.

Precertified is not the same as certified

The distinction matters for how the project is described. "IGBC Precertified Platinum" is accurate today. "IGBC Platinum Certified" is not — final certification follows construction and verification. Buyers comparing projects should ask which stage a rating claim refers to.

Several of these features also show up in the specification sheet rather than the amenities list — AC points in every bedroom and the living/dining area, aluminium casement windows, and apartments planned for cross ventilation with 90% of homes enjoying 3-side open views. Villas add a VRV air-conditioning system and an EV-charging provision as standard.

Why it matters to an owner

For a resident, the practical outcomes are lower common-area energy bills through solar lighting and LEDs, reduced dependence on municipal water through harvesting and grey-water reuse, and a home ready for an electric vehicle without retrofitting. For a buyer, the registration number is a checkable fact: IGBC lists registered projects, and the rating's progress can be tracked through to final certification.
