When NWESI was formed 45 years ago, the systems and technology were substantially different from those used today. For example, in our early years, no one had heard of a "cleanroom" or considered the importance of discreet HVAC systems within hospitals and other facilities that demand purity nor had they envisioned how technology would change the built environment.

While the work itself has expanded in scope and description, our approach is largely the same: we maintain a focus on professionalism, quality control and hands-on experience that continues to differentiate us. Our dedication to objectivity and thoroughness delivers better buildings, better projects, high performing systems and exceptionally satisfied owners and occupants.
