Thiscollection contains ASHRAE-published papers that describe researchinvestigating system efficiencies using parallel and series fan-poweredvariable-air-volume (VAV) terminal units. Descriptions of the findings fromASHRAE Research Project RP-1292 are described in the first six papers;additional research was undertaken to evaluate motor types and their associatedeffects in both terminal unit designs, which is covered in subsequent papers.Some of the latter papers also include research on energy modeling and how toget the research data into a format that programs such as the U.S. Departmentof Energy's EnergyPlus and other proprietary models can use.
