12-22 North Street is a ultra energy-efficient office and co-working space with a mission of operating sustainably while providing stable and affordable space for offices, meetings, and small events.

Built in 1980, our building was designed as a cutting-edge passive solar and energy-efficient building. However, due to poorly designed remodels over the years, the energy savings from its initial design became a hazard, leaving the top floor vacant for a decade.

In 2004, the building was purchased by renewable energy engineer AJ Rossman, who gave it a much needed face-lift, including installing Burlington’s first commercial photovoltaic solar array on the roof. In 2012, we installed the infrastructure for Burlington’s first smart microgrid including an electric water heater, relays to control LED lighting, electronic submetering, and ductwork and fans for night ventilation. As time went on, building energy improvements have continued, and in 2025 we completed the transition to air-source heat pumps, fully eliminating the building’s use of fossil fuels.

In 2022, a group of tenants joined the 12-22 North ownership group as minority partners, and collaborate on operating the building. As of 2026, we have 13 permanent tenants ranging, including lawyers, artists, remote workers, a hackerspace, a ginger beer micro-brewery, a labor union, an economic development non-profit, a videographer, and a print shop. We aim to cultivate an informal, collaborative, and fun community, and invite you to come check us out. If you like what you find, look for opportunities to join us for a day or a decade!
