One Partner for the
Life of Your Building
Borealis is an engineering consultancy. We find what your building's systems are really costing you, then get the upgrades designed, funded, and permitted — and keeps everything running the way it should. Owners, managers, and investors get one team from the first audit to the day-to-day.
Decarbonization and electrification studies that show which upgrades pay off, and in what order. Design and construction are delivered by our engineering partner, VD Engineering PLLC. We find, file, and administer the utility and government incentives that fund the work, and we expedite permits and sign-offs to keep projects on schedule.
