Alberta 1 – Accelerating Toward Net Zero Energy Ready 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 Alberta’s building enclosure requirements for Net-Zero Energy-Ready commercial buildings and how to detail highly insulated airtight building enclosures that achieve durability.

Event Information

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. The Calgary sessions will focus on NECB 2017 (National Energy Code of Canada for Building) and the adjustments needed to address thermal bridging calculations in that document.

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).
