The issues of energy consumption and occupant behaviors should not be an individualistic focus, assuming that people will control their behaviors and make rational choices. These complex issues extend to organizations and other social contexts as well. This presentation presents the empirical findings regarding the social-psychological and demographic variables affecting energy saving behaviors in both commercial and residential settings. In addition, the influence of social-psychological factors on the U.S. residents’ public acceptance of smart meters and demand response programs is presented. Importantly, this presentation discusses several important social science theories in measuring energy saving behaviors and intentions.
