AANB 2016 Industry Trade Show: National Energy Code for Buildings 2011 – How it Works with the Envelope

By

David Kayll, Building Science Specialist, and Dave Noel, Building Science Engineer

The National Energy Code for Buildings 2011 (NECB) is being adopted across the country as a standard approach for designing buildings to meet minimum energy targets. The use of the Code and how it integrates with Building Code and jurisdictional regulations will be discussed.  Examples showing how compliance to this Code differs from compliance with LEED and other rating systems will be used to explain how this Code is being adopted.  Methods for demonstrating compliance, coupled with reasonable building envelope practice, will be discussed.

AANB 2016 Industry Trade Show: Hidden Underperformers – Analyzing for Thermal Bridges in Building Envelope Design

By

David Kayll, Building Science Specialist, and Dave Noel, Building Science Engineer, will be presenting on the recently published Building Envelope Thermal Bridging Guide, which promotes energy-efficiency in buildings by addressing the often ignored issue of thermal bridging in building envelope design. The Guide is quickly becoming a useful reference for local jurisdictions, regulatory bodies, utilities and designers in determining the thermal performance of building envelope assemblies. This presentation will provide an overview of how the Building Envelope Thermal Analysis (BETA) Guide can be used to effectively account for thermal bridging, and develop a more accurate understanding of the overall effective thermal performance of a building design.  The effective thermal resistance of enclosure assemblies is essential information in evaluating building envelope thermal performance, for use in energy modeling, and to document performance and compliance for NECB code, ASHRAE 90.1, and LEED or other rating purposes.  Insights from project team members relating to current design practice and next steps will also be shared.
