Deep Energy Retrofit Forum: Thermal Bridges

By

Mark Lawton, Senior Building Science Specialist, will be presenting on Thermal Bridges at the Deep Energy Retrofit of Buildings Forum. The Forum will focus on Technical and Business Strategies.

When buildings are renovated the energetic targets are usually kept to the minimum requirements resulting in a reduction of energy use in typical retrofit projects between 10 and 20%. Considered from the perspective of a life- cycle of a typical building this approach is a “lost opportunity.” Recent research from actual executed energy projects around the globe shows that energy reduction can exceed 50%, and that renovated buildings can cost effectively achieve the passive house standard or even approach a net zero energy status.

Formal presentations by international experts will be complemented by moderated formal and informal discussions, networking and technical exhibits demonstrating the state-of-the-art technologies and best practices used in Deep Energy Retrofit projects. This forum is designed for decision makers, public building owners, energy managers, planners, engineers, architects, energy performance companies and industry partners involved in major renovation of buildings.

This Forum is presented by the Federal Facilities Council of the National Academies of Sciences, Engineering, and Medicine in partnership with the International Energy Agency EBC Program Annex 61, US Army Corps of Engineers, U.S. General Services Administration, the American Society of Heating, Refrigerating and Air-Conditioning Engineers and the U.S. Department of Energy.

BC Building Envelope Council Conference & AGM: Drainage Capabilities & Heat Loss of Different Roof Assemblies

By

Matthew Pel, Building Science Consultant, will be presenting Drainage Capabilities and Heat Loss of Different Inverted Roof Assemblies at this year’s BC Building Envelope Council Conference & Annual General Meeting.

Energy use in buildings throughout BC and Canada has attracted significant attention over the past decade. In BC, rainwater management is a critical aspect of designing a durable and energy efficient building envelope. This HPO funded presentation will provide an overview of the research completed by Morrison Hershfield relating to different drainage scenarios for inverted roofs and the associated heat loss for the different drainage. Items evaluated during this project include:

  • Testing instruments and equipment
  • Heat flux through the different inverted roof assemblies
  • Leakage rates in terms of water drainage a the surface of the insulation and the membrane level

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.

AIA Seattle CAP Collaboration Series: Building Envelope Commissioning (BECx)

By No Comments

Stevan Vinci, Building Envelope Commissioning & Sustainability Specialist, will be presenting as part of AIA Seattle’s Corportate Allied Partner Collaboration Series on the topic of Building Envelope Commissioning (BECx). BECx is a topic that will enable architects to be prepared for not only the new changes implemented in LEED v4, but also to keep current on how efficiently certain building envelope assemblies can perform.
