British Columbia Session 2 – Accelerating Toward Net Zero Energy Ready With Durable Building Enclosures


British Columbia Session 2 – Accelerating Toward Net Zero Energy Ready With Durable Building Enclosures

Data indicates that carbon emissions are altering the Earth’s climate, pushing commercial building codes toward Net-Zero Energy-Ready performance requirements. This is part one of a two part series that focuses on British Columbia’s building enclosure requirements for Net-Zero Energy-Ready commercial buildings and how to detail highly insulated airtight building enclosures that achieve durability.

British Columbia Session 2 – Accelerating Toward Net Zero Energy Ready With Durable Building Enclosures

Commercial building codes are navigating toward the performance requirements of Net Zero Energy Ready buildings due to climatic data that indicates carbon emissions are altering the Earth’s climate. Today’s building occupants also expect increased levels of performance and comfort which, can only be achieved with a high-performance building enclosure. When these buildings are detailed right, during the design phase of construction, they are both durable and cost-effective to build.

This seminar will focus on the building enclosure requirements of a Net Zero Energy Ready commercial building and you’ll learn how to detail highly insulated airtight building enclosures that achieve durability. To assist the design team, calculation tools will be examined that can guide the team to efficient and durable building enclosure details that are cost-effective. The session will be capped off with a review of strategies that have and have not worked in low TEDI (Thermal Energy Design Intensity) buildings to date. It will also place an emphasis on BC Step Code and Passive House in the BC market.

Learning Objectives:

• Moving to net zero energy ready through building codes.
• Conversion then generation: optimizing building enclosures with air tightness and exterior thermal resistance.
• From slab to foundation walls to roof: continuous water, air and thermal control layers.
• Details matter: creating durability in highly insulated building enclosures.
• Calculating complex thermal resistance values and bridges with design tools.
• Show me how it’s done: case studies of low TEDI buildings (Thermal Energy Design Intensity).



Alex Blue, P.Eng., LEED AP BD+ – Principal, Building Energy Practice Lead

Alex is the Building Energy Practice Lead with the Building Performance Analysis group. She works on energy and comfort analysis for buildings, focusing on guiding design for energy efficiency and reduced lifecycle cost, as well as demonstrating compliance with building codes, LEED, and incentive programs. Alex has been involved in commercial, multi-unit residential, and institutional projects across Canada and the US. Alex has performed energy analysis for NPC assessment and optimization, and has performed calibrated modelling for M&V both for LEED and acting as the third-party verifier for P3 performance guarantee projects. She has been involved in developing M&V plans and performing calibrated modelling for projects ranging from multi-use buildings, including residential occupancies to hospitals to data centres.


Neil Norris, P.Eng, CPHD – Building Science Consultant

Neil specializes in the research and evaluation of the thermal performance of the building envelope, including 2D/3D thermal modelling and in-situ monitoring and testing of real life building systems. As a main contributor to the Building Envelope Thermal Bridging Guide and a certified Passive House Designer, Neil has a deep understanding of how thermal bridging can impact the performance of the building envelope. Neil works with manufacturers and project teams to analyze and understand how to reduce thermal bridging from their envelope designs.
