Webcast Series 1 – Duct Camp

Series Objectives

THIS SERIES WILL.…

Identify what we expect ducts to do for us and not to do.
Reveal how ducts are really performing. Present an overview of the past two decades of research on duct systems regarding leakage, thermal losses, energy savings from repair, cost / benefit studies, avoided peak capacity, comfort issues, increases in delivered capacity of equipment gained by repairing ducts, etc.
Introduce comprehensive duct diagnostics procedures, including: preliminary screening, visual inspection, tools and tests, what they tell us, why we want to know, how to decide what to test for (but not step-by-step procedure training on each of them).
Present a general overview of duct design and ACCA Manual “D.” This is not an in-depth training session on every aspect of Manual “D,” but rather an introduction to the basic principles of design and why they are important. Learn rules you should know and follow when building or repairing ducts. Explain what causes high static pressure in a system and demonstrate ways to manage it.
Impart practical field applications of ACCA Manual “D” for new and existing ducts, and demonstrate how to recognize when they have been violated. Offer some “Real Rules of Thumb” you can trust in the field. Explain logistics for new duct layout and duct repair to help facilitate compliance with ACCA Manual “D” principles. Show some common problems and solutions.
Present quality duct construction and repair materials, techniques and time-effective, innovative procedures. Address thermal protection and vapor barrier construction for ducts outside conditioned spaces.
Delineate five basic house / duct configurations, common problems and shortcuts found in each one, prominent issues to inspect, and step-by-step procedures for correcting them.

By attending the ACI Webcast series on ducts, participants will

Recognize opportunities for improvements in duct systems, as well as the components necessary for installing ducts correctly
Be enabled to embrace a holistic way of approaching ducts that includes but is not limited to: design criteria, accessibility, insulation and vapor barrier performance, total system airflow and balancing, static operating pressure, return sizing, leakage / tightness, pressures exerted by ducts on the house and zones related to safety and efficiency, basic “triage” considerations, new system design, materials and techniques selection, evaluation and testing criteria, comfort corrections and register selection, and sizing relative to the equipment and actual load needs
Recognize what you do not know, determine which topics you want to know more about, and find out about further resources and training options
