    Please join APT WGLC for a noon virtual presentation by Manogna Kavuru, Ph.D.

    Infrared Thermography for Existing and Historic Buildings

    Thermal imaging offers a quick and non-invasive way to uncover potential issues in buildings, but to use it effectively, understanding the nuances is key. This presentation explores the challenges of interpreting thermal data, especially in buildings with limited documentation. Environmental factors, building materials, and moisture can all impact results, creating ambiguity if not properly considered. Through real-world case studies, we’ll highlight best practices for more accurate analysis and share tips for those new to the technology. Whether you’re just starting or refining your skills, this session will help you get the most out of your thermal camera.

    Learning Objectives:

    1. Explain the use of thermal imaging as a tool to discover water and air leaks.
    2. Define parameters that affect thermal imaging that help examine facades and roofs effectively.
    3. Describe environmental factors that cause differences in thermal images.
    4. Explain how building assemblies show up differently in thermal images.

    Manogna Kavuru, Ph.D is a Senior Designer with Thornton Tomasetti and has over 8 year's experience using thermal imaging as a diagnostic tool with projects in Bermuda, India, Italy, Turkey and the USA. Her doctoral dissertation focused on the use of thermal imaging as a potential tool to conserve masonry structures in tropical climates, like India. She is also a Level II thermographer.

    An email link to the presentation will be sent to those who register after registration closes, approximately one day before the presentation.

    1.0 AIA/CES LU will be provided (pending approval).
