A 1960s condo on Manhattan’s East Side was staring down carbon fines that would climb past $250,000 a year — until its board decided to act. Michael Scorrano, managing director and founder of the EN-POWER GROUP, a Verdantas Company, walks through how they swapped an aging, gas-fired heating and cooling system for electric chillers and heat pumps, all without disturbing a single shareholder’s apartment. He breaks down how the building tackled its fuel switch and what other boards can learn, from the surprising mechanical hiccup that slowed things down mid-project to the rebate programs that helped offset the cost. Habitat’s Carol Ott conducts the interview.
