From single family homes, to multi-million dollar developments, our team of engineering professionals has supported hundreds of commercial and residential projects.

OUR history

Optimize Envelope Enigneering (OEE) was founded by Dana Bjornson P. Eng, M. Arch in 2010 following her tenure at Williams Engineering and Halcrow Engineering as a building science specialist. Her team of building professionals has continued to grow through a series of banner projects in Western Canada; including Calgary’s West LRT transit project, Canalta’s sprawling rural hotel expansions and high-profile rehabilitation projects such as the TD Square Devonian Garden reconciliation and renovation.

OEE brings to all of its clients a wealth of industry experience in commercial construction and residential projects. We excel in providing essential insight and approvals in the new building process and forensic-level insight into past building deficiencies. With hundreds of first-hand case studies to draw from in building function and dysfunction we are confident in our capacity to deliver an optimized building realization to meet all the needs of clients and constructors.

Operating primarily in the greater Calgary area including Rockyview MD, Foothlls MD and beyond, OEE works closely with public municipalities and private construction professionals to continuously satisfy and advance best practices in building envelope design and implementation.
