CS3.3: Envelopes: modelling and best practices

Friday, November 15, 2024
4:00 PM – 5:30 PM EST
CE: 1.5

General Admission/Adminsion générale Simultaneous Interpretation Available/Interprétation simultanée disponible AIA CES Approved

This session has qualified for 1.5 LU|HSW Credits

This program is a mix of case studies, best practices guidelines and data driven solutions from professionals contributing to the resilience of existing buildings. The program is most beneficial for attendees who have baseline understanding and some direct experience with the topics. First we will discover air leakage testing in heritage buildings and how it can help reach GHG emission reduction targets by identifying problematic areas at the design phase. Through a case study we then will dive into thermal and carbon performance of the wall assemblies, discussing methodologies, optimizations, and recommendations. Third, we will discover how machine learning can improve retrofit rates and the challenges created by underrepresented data on heritage buildings. Finally, the impact of climate change will be revealed through the analysis of chloride deposits patterns in coastal 19th century masonry buildings.

HSW Justification
Modeling and data driven solutions are key tools in enhancing the performance of historic building envelopes and systems, thus enhancing occupants health, safety and well being. This sessions will demonstrate the importance of understanding the mechanisms that impact the performance of materials assemblies, as well as the need for informed extrapolation when available data is limited. It touches upon all three aspects of HSW with topics ranging from retrofitting for enhanced performance, to increased sustainability, resistance to worsening coastal flooding, and data monitoring to guarantee long-term performance

Learning Objectives:

  • Upon completion, participant will acquire knowledge on how machine learning is being used in retrofitting buildings and how it can help solve barriers to retrofitting.
  • Upon completion, participant will be able to identify the major embodied carbon differences between new masonry wall construction and retrofits of existing assemblies.
  • Upon completion, participant will discover the impact of frequent coastal flooding on 19th century masonry construction building through chloride deposits pattern data.
  • Upon completion, participant will be able to define what whole building air leakage testing is and how it can be used in the design of a building rehabilitation.
