Founded in 2011 to prove that sustainability pays.
Our story
Greendian began as a small team of mechanical and electrical engineers convinced that most buildings waste more than half the energy they consume — and that fixing it should be as measurable as the waste itself.
Fifteen years later, we operate across 18 countries, running programs for hospitals, universities, data centers and manufacturers. Every project is guided by the same principle: instrument first, then engineer.
We're proud to be an employee-owned company, a certified B Corp, and one of the few energy services firms whose contracts guarantee performance rather than promise it.
Engineering-led
Every recommendation is grounded in measurement, modeling and site-level evidence.
Outcome-based
Contracts are tied to verified savings — we win when the meter drops.
Independent
Vendor-neutral by design so we specify what's best, not what's ours to sell.
Long-horizon
Most partnerships last a decade. We're built for what happens after commissioning.
Certifications & credentials
Our work meets rigorous third-party standards — from EPA lead-safe practices to ISO 50001 energy management and LEED project partnerships.
