CS3.1: Carbon in heritage

Friday, November 15, 2024
8:30 AM – 10:00 AM 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 session explores the multifaceted relationship between conservation and sustainability, addressing diverse building scales from large historic structures to single-family homes. We will begin by defining sustainability terminology and then delve into how heritage and existing buildings can align with contemporary sustainability goals. Topics include the role of historic buildings in promoting sustainable development, deep energy retrofit techniques, and strategies for improving operational carbon efficiency in various types of buildings. The session will also address the effects of climate change on our existing building stock, focusing on interdisciplinary collaboration to predict the impact on preserving building envelope materials such as bush-hammered concrete. Through case studies, practical experiences, and technical insights, participants will develop a comprehensive understanding of integrating heritage conservation with contemporary environmental standards, ensuring resilience and sustainability across building types.

HSW Justification
All four learning objectives relate to the HSW topics of Programming & Analysis, Project Development & Documentation, and Construction Evaluation. The course will: 1) explore the constraints and opportunities of heritage buildings in the context of sustainability goals, 2) analyze the integration of deep energy retrofit techniques and other sustainable strategies to improve operational carbon efficiency, and 3) address post-occupancy evaluations by assessing the effectiveness of sustainable strategies through data collected on building performance.
This presentation will address the following HSW topics: 1 - Improved operational carbon efficiency is critical to enhancing the performance of historic resources facing the physical and economic impacts of climate change.. Reaching that goal while maintaining historic fabric and significance require technical dexterirty, and informed application of technical innovations. 2 - Enerfy retrofit interventions in historic building requires multidisciplinary, collaborative decision-making, and regulatory stakeholder buy-in in terms of applicable codes and potentail variances. 3 - Historic buildings represent baseline embodied carbon footprint, but their potential to support overall sustainability goals extends well beyond that baseline; technological innovations and lessons learned providing opportunities to enhance safety and wekllbeing by mitigating the effects of climate change on a wide range of materials and structures.

Learning Objectives:

  • Upon completion, participants will be able to illustrate the role of heritage buildings in promoting sustainable development by evaluating how historic buildings contribute to modern sustainability goals and exploring practical strategies for harmonizing these with regulatory requirements.
  • Upon completion, participants will be able to analyze and strategize deep energy retrofit techniques for historic buildings, addressing the technical challenges, economic impacts, and local adaptations needed to meet energy efficiency standards.
  • Upon completion, participants will be able to identify methods for improving operational carbon efficiency in heritage buildings, considering both embodied and operational carbon, and integrating these into conservation planning across diverse building scales.
  • Upon completion, participants will be able to collaborate across disciplines to address the preservation of existing structures in a changing climate, focusing on the development of methods to monitor and mitigate the impacts of climate change on building materials like bush-hammered concrete.
