Hospital Energy rebrands as Environ and merges with Gotham 360

Hospital Energy, the nation’s leading energy firm for healthcare, announced it has rebranded as Environ Energy and has merged with Gotham 360, a renowned energy sustainability firm. Environ will offer best-in-class sustainability strategies and energy management expertise to organizations with large and complex energy needs. The move was made possible with support from 424 Capital, a growth capital investor that works in partnership with founders and management teams to accelerate and scale for long-term growth.

“Energy management is becoming increasingly sophisticated, and there are advantages to our clients that come with scale and a growing culture that includes some of the best energy professionals in the business,” said Mark Mininberg, CEO of Environ and Hospital Energy’s founder. “Our new incarnation will allow us to provide an expanded suite of services to our existing healthcare clients, while expanding into new market segments, including higher education, corporate real estate, data centers and manufacturers, among others.”

Environ will offer a full range of energy services including procurement, efficiency, resiliency, sustainability and compliance reporting to businesses and non-profit organizations throughout North America. The firm builds on Hospital Energy’s financial best practices approach to energy management, and Gotham 360’s broad experience across a range of sustainable energy skills, including project development and management, carbon reduction strategies and ESG reporting.

“By joining with Environ, we are able to bring the rigor and expertise that our team is known for to a broader market,” said Jennifer Kearney, who will continue as president of the Gotham 360 division at Environ, which she founded in 2007.  “As we come together in this new company, we quickly realized our teams share a passion for promoting sustainability and solving complex energy problems with innovative, financially-smart strategies.”

The new company unveiled its brand with a new website:
