Past Event: July 24, 2020 @ 12:00 pm – 1:00 pm
The Twin Towers in North Vancouver has the potential to become the world’s largest multi-family EnerPhit project. The development consists of two concrete high-rise residential towers, providing more than 210 affordable homes. The ground is made up of multi-level commercial and retail spaces, adding complexity to the project. Combined, the towers are 26 stories high and span a Treated Floor Area (TFA) of nearly 10,000 m2.
Impact Engineering and Morrison Hershfield were hired by BC Housing & Affordable Housing to outline a retrofit pathway that meets EnerPHit requirements and delivers full electrification of mechanical systems for the residential towers. At 42 years of age, the building’s envelope components require attention and mechanical systems are at end of life.
Key project team members will discuss their approach to this challenging problem, feasibility study results, including relative costing, and their recommendations. Lessons learned will be shared to assist other teams to get the most out of their Deep Retrofit projects.

Patrick Roppel, M.A.Sc., P.Eng., Principal and Building Performance Analysis Department Manager – Morrison Hershfield,
Patrick has over 15 years of consulting experience related to building science and building envelope energy efficiency. His focus has been providing tools and guidance to help practitioners make design decisions related to constructability, thermal, structural, energy, and hygrothermal performance. His field experience, monitoring and investigations of existing buildings, computer analysis of envelopment components and systems, and development work is leveraged on new-construction projects to set realistic and practical expectations for building envelope performance. Patrick has led several successful landmark projects such as the Building Envelope Thermal Bridging (BETB) Guide and Guide to Low Thermal Energy Demand for Large Buildings (Low TEDI Guide).
