Measured occupancy diversity factors for use in building energy simulations are rare in general and practically nonexistent for university type buildings. To better understand occupancy schedules (or diversity factors) for university buildings, six types of university buildings (eleven buildings in total) were considered in this study: administrative, library, recreation, architecture, research, and classroom. Two occupancy schedules were derived for each building type; a 'similar-day' schedule and a more generic 'weekly' schedule. In addition, a simple method was developed to easily predict occupancy diversity factors for classroom-type university buildings. (C) 2010 Elsevier B.V. All rights reserved.
