The AI answer we saw
For IGBC green building certification, dual flush toilets with a 3/6 litre flush volume are typically required to meet water efficiency credits. Brands like Kohler, Jaquar, Roca, and Duravit offer WaterSense or equivalent certified dual flush suites. Ensure the product has documented flush performance data (ECBC or equivalent compliance) to submit during IGBC documentation. Models with 4.5/3 litre ultra-low flush options provide higher water efficiency points. Confirm with your IGBC consultant on the specific credit requirements (WE credit under IGBC rating system) before product selection.
