1.5 ConEd Learning Hours

Whole-building air leakage (WBAL) testing 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 Passive House retrofit in a campus setting will be presented.

Learning Objectives:

1. Understand the basic approach to whole-building air leakage (WBAL) testing.
2. Understand how WBAL testing applies to high-performance buildings (PHI/ZCB/NZEB) in Ontario, and the value it provides.
3. Learn the specification of the above principles to more complex conditions such as interconnected buildings and multi-building campus conditions.
4. Experience a case study of a Passive House retrofit in a campus setting.

Steve Murray has broad experience in rehabilitation and retrofit of existing buildings involving roofing, cladding, masonry, curtain wall, exterior insulation and finish systems (EIFS), and windows. Steve has also developed expertise with six-storey timber-framed and 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 thrives in providing architect and developer clients with envelope design assistance, design review, BECx, and energy optimization advice.
