The largest energy expense in US buildings, more than a quarter total energy consumption, is around cooling and heating [23]. In the Aderhold Learning Center building the temperature range has been centrally set between 64 and 72◦F. If the thermostat of Aderhold Learning Center building is adjusted by 2◦, the degree days of cooling and heating will be reduced by 21% and reduce overall energy consumption of Aderhold Learning Center building by about 5% (Appendix A). This motivated us to investigate how social norms could be used to influence the support of the users of this publicly owned building for a voluntary permanent thermostat adjustment to save energy and reduce costs to GSU.
