Gain an understanding of the energy performance and costs of both displacement ventilation and dedicated outdoor air systems in our course prepared by Steven Liescheidt, PE, CCS, CCPR. This PDH-accredited course describes the principles and practical applications of displacement ventilation and dedicated outdoor air systems for commercial buildings. 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) in order to separate the outdoor air ventilation and space conditioning functions in dedicated outdoor air systems, or to distribute air to achieve thermal stratification within the space. This online engineering course is based on, "Initial Evaluation of Displacement Ventilations and Dedicated Outdoor Air Systems for US Commercial Buildings", NISTIR 7244.
