E – 1581 Displacement Ventilation and Dedicated Outdoor Air Systems

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 that distribute air to achieve thermal stratification within the space.

This course describes 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.

This course is based on the material contained in the Initial Evaluation of Displacement Ventilations and Dedicated Outdoor Air Systems for US Commercial Buildings, NISTIR 7244, July 2004.
Once you complete your course review, you need to take and exam consisting of ten (10) questions at the end of this course to obtain PDH credits.
