“I had a 2KW rooftop solar system installed, and since then, I haven’t had to pay my electricity bill," said Patil, who is an electrical engineer. He installed air conditioners after the rooftop solar system was put in place, so his electricity bills did not factor in the additional usage. Patil’s rooftop solar system is immune to this problem and there are no extra costs attached. “But the builders I met had little clue about what a green building meant," he said. LEED is one of the most popular green building certification programmes used globally.
