ABSTRACT
The article provides information on a spreadsheet tool for simplifying the selection of rooftop units. It states that spreadsheet entries are discussed section-by-section to better understand their uses. It notes that spreadsheets enable engineers to select rooftop units and carry out heat balance in a rooftop-unit system.
