1.5 ConEd Learning Hours
8:30 a.m. ‐ 10:00 a.m.
Whole Building Air Leakage Testing (WBALT) is becoming a requirement in many high‐performance buildings. Multi‐use, campus, and retrofit building scenarios involve separating interconnected spaces for WBALT, which can prove challenging. A case study of a PassiveHouse retrofit in a campus setting will be presented.
Learning Objectives
1. Understand the basic approach to Whole Building Air Leakage Testing.
2. Understand how WBAL testing applies to high‐performance buildings (PHI/ZCB/NZEB) in Ontario, and the value it provides.
3. Apply these principles to more complex conditions such as interconnected buildings, building expansions, and multi‐building campus conditions.
4. Learn about a case study Passive House retrofit example in a campus setting.

Morrison Hershfield
Steve Murray has broad experience in new construction, rehabilitation of existing buildings, and deep energy retrofits targeting Passive House and Zero Carbon performance. He has developed expertise with six-storey timber-framed low-rise structures and multi-storey mass timber buildings and the unique envelope challenges they entail. Recent work has focused on high-performance buildings pursuing Passive House and Zero Carbon Building certifications, and the Building Envelope Commissioning (BECx) processes necessary to achieve these objectives. Steve has particular expertise with pre-fabricated envelope systems for both new construction and retrofit projects. He thrives in providing architect and developer clients with envelope design assistance, design review, and energy optimization advice.
Levi J. Brown, B.Eng., EIT
Building Science Consultant, Morrison Hershfield
Levi Brown has specialized expertise with Whole Building Air Leakage Testing of new buildings and additions to existing buildings targeting Passive House and Zero Carbon performance. This expertise adds to his new construction experience with cladding and below-grade waterproofing design and construction review. Levi’s new construction work is informed by an understanding of deterioration mechanisms developed from his work in assessment, investigation, and rehabilitation of existing buildings. Levi also has experience with facility condition assessments of large facilities like correctional institutions and airports.
