Considerable research has been conducted on the leakage levels of various types of ducts and duct fittings. Electricity energy savings potential by eliminating air leakage from ducts in large commercial buildings is on the order of 10 kWh/m2 per year. The research discussed in this paper is based on two large commercial buildings, using a new technology that simultaneously seals duct leaks and measures effective leakage area of ducts.

In this course the student will learn about the importance of duct sealing with respect to saving energy in air delivery systems in commercial buildings. The student will also be made aware that the duct sealing method analyzed in this report is technically viable; however, more work is needed to develop a practical cost effective methodology for this process.

The student is expected to read and review the material contained Duct Sealing in Large Commercial Buildings with Aerosolized Sealant Particles, LBNL - 42414.

The student must take a multiple-choice quiz consisting of ten (10) questions at the end of this course to obtain PDH credits.

State Board Acceptance

This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states that mandate continuing education for engineers, it is the individual engineer's responsibility to determine the suitability of activities for PDH credit. The state boards typically accept online* courses that cover technical, managerial** or ethical content and which are relevant to the practice of engineering. The course must have a clear purpose or objective with a content that will maintain, improve or expand the skills and knowledge of the licensee's field of practice. For questions about your mandatory PDH requirements, visit the website of your state licensing board.

*Online courses are accepted by all state licensing boards that mandate continuing education. Other than New York (which limits online courses to 18 PDH) and Iowa (which limits online courses to 6 PDH), there are no limits placed by other states on the number of hours that can be earned through online continuing education. Consult with your state licensing board if you have any questions about the acceptability of online courses.

**The New York State Board of Engineers does not accept general office management courses, but will accept project management courses that are offered by an approved provider and that are technical in nature and contribute to the engineer's professional practice.

Please Note: Continuing Education credits for this course are awarded as PDH (Professional Development Hour Credits).
