About us
Exergio is a project that emerged from years of experience in building maintenance.
We are often asked by building managers how to improve energy efficiency and reduce costs without major capital investment. Having closely followed market developments—from mechanically controlled systems to autonomous BMS—we’ve seen many misconceptions. A common one is the belief that using quality materials, installing a building management system, and meeting sustainability certification criteria guarantees maximum energy efficiency.
But this is not the case. Energy efficiency goes beyond initial investments. Exergio addresses this gap with practical, cost-effective solutions built on real-world experience.
