Facades Week LA! 2020: Two Presentations

The Facade Tectonics Educational Workshop will provide practical guidance and hands-on exercises on how to specify fenestration systems effectively, how to manage thermal bridging on the envelope and how to assess thermal comfort next to the envelope to assess and optimize the comfort performance of your envelope design.

Pre-workshop Overview: A Practical Guide to Delivering a High-Performance Envelope

This educational workshop will provide practical guidance and hands-on exercises on how to specify fenestration systems effectively, manage thermal bridging on the envelope, assess thermal comfort next to the envelope to assess and optimize the comfort performance of your envelope design.

Participants will review how to assess occupant thermal comfort using ASHRAE Standard 55 methodology, using non-uniform mean radiant temperature created near the building envelope and the impact of direct solar radiation. During the session, we will use on-line software tools to evaluate and compare how fenestration performance impacts occupant comfort.

Workshop Objectives:

1. Understand how to meet more stringent fenestration U-factor requirements, how to effectively specify, and why U-factor in isolation is not sufficient to deliver a high-performance fenestration system.
2. Be able to explain why the edges of fenestration matters and know how to specify the edge of glass to ensure high thermal performance without sacrificing durability.
3. Understand the importance of thermal bridging and be able to implement strategies and tools to calculate the effective thermal performance of façade systems using clear field U-values for assemblies and linear transmittances to account for the additional heat loss at interfaces. Be aware of available tools, and know how to select project specific assemblies to develop effective thermal performance values that can be incorporated into whole building energy models to more accurately assess the impact of façade systems on whole building energy consumption. Be able to explain the concept of temperature Index and how it can be used to assess the impact of thermal bridging on condensation risk.
4. Understand how to assess thermal and visual comfort next to the building envelope, and what strategies can be implemented in order to improve thermal and visual comfort.

Stéphane Hoffman, Vice President & Senior Building Science Specialist, will participate in this workshop. Purchase tickets here.

Session Overview: Façade Mock-Ups – Laboratory Testing of Glazing Systems as Part of a Quality Assurance Program

This presentation assesses the importance of lab testing as part of a quality assurance program and will present a variety of different failures that have occurred during laboratory mock-up testing. Learn how the testing reveal deficiencies in the design, assembly, or installation of the glazing systems.

Andy Lang, Facade Specialist, will participate in this panel session.
