Introduction to Low-Cost Remediation of Misapplied Foam
Henri Fennell, Consultant, HC Fennell Consulting, LLC, North Thetford, VT
About this program:
It is generally accepted that the only guaranteed remediation for misapplied foam is its complete removal. This method is almost always catastrophically disruptive and expensive. A new method, with a high success rate, but with an “orders of magnitude” lower cost, uses an isolation and depressurization approach similar to radon mitigation. Seven case studies of successful remediation projects will illustrate this “instertial space depressurization system.”
By attending this session, attendees will:
• Learn how to design an instertial space depressurization system for misapplied foam projects
• Be able to select and size the equipment required for this system
• Be able to verify that the system is providing a safe indoor environment before allowing re-occupancy
About the Presenter:
Henri Fennell is a building envelope specialist and architect with forty-five years of experience in energy conservation design, manufactured products, and services. His work with polyurethane foam began during the energy crisis of the 1970s.
His experience has included practicing architect and building envelope remediation and commissioning consultant. Major historic projects include the Guggenheim Museum. He has designed several new micro-load buildings, including a cutting-edge net-zero energy research structure in Antarctica.
For the last ten years he has developed and implemented remediation plans and standards for misapplied foam projects.
He has four energy-related U.S. patents, and has contributed to ASTM standards, ASHRAE Journal, and is often cited in articles related to energy conservation and building performance.
