Overview

Conventional heating, ventilation and air-conditioning systems in commercial buildings meet both outdoor air ventilation and space conditioning requirements using air distribution approaches that provide a mixture of outdoor air and recirculated air with the goal of achieving good air mixing within the occupied space. More recently, advanced ventilation approaches have been proposed, and in some cases installed, that separate the outdoor air ventilation and space conditioning functions (dedicated outdoor air systems or systems that distribute air to achieve thermal stratification within the space).

In this course the student will learn about the principles and practical applications of displacement ventilation and dedicated outdoor air systems for commercial buildings. The student will gain an understanding of the energy and cost related to using these two types of systems.

The student is expected to read and review the material contained in the Initial Evaluation of Displacement Ventilations and Dedicated Outdoor Air Systems for US Commercial Buildings, NISTIR 7244, July 2004.

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).
