Who We Are

Integral Performance Engineering

We believe that engineering services for building systems are integral to the overall success of every project. Performance is about delivering deep green engineering solutions, and accelerating sustainable, environmentally-positive changes in a collaborative and forward thinking way.

A focus on best practice and innovation makes us strive towards cost effective and pragmatic outcomes, as we believe system optimization is at the heart of every sustainable building. As we move towards increasingly higher performance and lower-resource buildings, we are constantly re-testing our assumptions and designs as fuel prices change, resources deplete, and new techniques or technologies emerge.

Integral Performance Engineering, now a member of and operating as the Integral Group, has been in existence since 1989, when we began operation as Ai Engineering in Washington DC. The firm has expanded with offices currently located in the Washington, DC Metro area; Richmond, Virginia; Raleigh-Durham, North Carolina; and San Francisco, California.
