The rating levels recognized within the Estidama system include 1 Pearl, 2 Pearls, 3 Pearls, 4 Pearls, and 5 Pearls. Each level signifies a different threshold of sustainability accomplishments, with 1 Pearl being the minimum acceptable standard and 5 Pearls representing the highest standard of sustainability.
