As practitioners, we use our knowledge and experience to produce successful energy efficient designs that improve our clients’ environments and create desirable conditions for day-to-day operations. But how well are we doing? What happens when people use the building? Post-occupancy energy performance may be compared to predicted results and inform the best way to adjust our designs, as well as initiate occupant behavior-based strategies. This session will show predicted and measured energy and daylighting performance as well as exemplar behavior-based energy conservation programs (20%-37% energy savings) in K-12 schools and in a government agency. We will show data, share attributes of the successful programs, overview of the strategies implemented to involve students/users/employees in saving energy and increasing awareness to sustainability.
