Built Environment Engineers is a mechanical, electrical, and plumbing consulting engineering firm that understands architecture and design. We are driven by the notion that excellent architecture is defined also by excellent engineering -  elegant, efficient, maintainable, and within the client’s budget.

Our principals -- all rooted in design -- approach engineering with a deep appreciation for  architecture and its role in society and relationship to the natural environment.

Instrumental to our success is our keen understanding of project schedule and how our performance impacts architecture and ultimately the client’s program.

Built upon creative and collaborative solutions, our team delivers excellent engineering from the first design charrette to final building commissioning.  

  • One firm providing engineering services as an integral team member
  • Large firm experience, small firm responsiveness:   our principals each have over 20 years of proven excellent project delivery.  We bring that maturity to every engineering challenge.
  • Principals who are leaders in local and national industry groups – ASHRAE, USGBC, DC Mechanical  Code Group, ABET, NCEES, 7x24Exchange
  • SWaM certified in Virginia

Built Environment Engineering is focused on results.


Built Environment Engineers approaches problems differently, without the constraints of a large business, and we are proud to put our stamp on inspired designs.
