2025 BES Session: Enclosure Rehabilitations: Using a Collaborative and Holistic Process to Maximize Value (Zeigler, Huynh)

Course Overview
This session was originally presented at the 2025 IIBEC Building Enclosure Symposium in St. Louis, Missouri.  This course includes the following components:

• recording of the live session
• a summative assessment consisting of 10 multiple-choice questions
• two surveys required to claim continuing education credit

Description

Rehabilitation of existing building enclosures offers technical designers the opportunity to optimize building performance while bridging the owner’s goals and providing value for the owner. This paper outlines the benefits of early-stage planning and communication with an integrated holistic approach implemented throughout the predesign phase. For a technical designer, the amount of effort should be maximized in the predesign phase to maximize overall project value. Key tasks from the predesign phase are outlined. These include forming a team, identifying urgent issues and long-term goals, developing an owner’s project requirements, investigation, and site assessment. To conclude the predesign process, documentation that summarizes and materializes the findings and details of the predesign phase is also discussed, as are the design and construction phases. Roofing case studies including dead load and wind uplift calculations are used to exemplify the benefits of placing emphasis on the predesign phase to increase value for the owner. 

Course Recommended Prerequisite(s)
The ideal level of prerequisite knowledge for this presentation includes the fundamentals of enclosure/roofing design and the general process for design and construction. Learners who understand building enclosure design concepts, including terminology and materials, will benefit the most.
