We don’t stop at installing solar panels and reducing carbon emissions. We’re urban beekeepers— literally housing these champion pollinators on rooftops. We’re using an abandoned quarry as a renewable source of water for an innovative cooling system. And we’re harvesting hundreds of gallons of rainwater. Boston’s most sustainable building? That’s one of ours, too.
