The duration of time spent at the receptacles in the current experimental study and in our observational study [26].

<p>Participants spent significantly more time at receptacles in the current study compared to patrons in Wu et al. [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0145737#pone.0145737.ref028" target="_blank">28</a>].</p

The number of times containers, organics, and garbage receptacles were selected in a sustainable building versus a non-sustainable building.

<p>Participants in the sustainable building condition used the garbage receptacle less than those in the non-sustainable building. As noted by the asterisk this difference was significant between the buildings.</p

Examples of how the CIRS building conveys an atmosphere of sustainability to users.

<p>From top left to bottom right: water collection and purification system, signage in washroom about the water collection and purification system, 3D signage at waste receptacles in the café, extensive use of wood in the building’s construction, messaging on paper napkin holders in the café, LEED platinum certification display in the lobby, signage by the elevators to increase the use of stairs.</p
