The central thrust of this paper is to provide automation and control design guidance for engineers considering dedicated outdoor air systems (DOAS) operating in parallel with ceiling radiant cooling panel systems (CRCP) in nonresidential commercial and institutional applications. The paper identifies the issues that must be addressed in the design of the control system and illustrates that the controls need not be complicated. The simplicity of the controls is demonstrated via a case study of an existing DOAS-CRCP facility. Finally, the control challenges presented by low-occupancy spaces such as offices will be contrasted with those of high-density spaces such as schools and places of assembly.
