A technology-aided social marketing approach for domestic hot water consumption reduction in a multi-unit residential building Iniesta, Edgar David Sotelo


The purpose of this project was to examine the effectiveness of a behavioral change pilot program aimed to reduce hot water consumption in the Clement's Green residential building located at UBC Vancouver campus. The project was supported by an online communication tool provided by BuiltSpace Technologies and hot water sub-metering provided by Enerpro Systems. During this project, a new method for providing consumption information to building occupants was pilot tested as a means to stimulate a reduction in hot water consumption. This strategy was underpinned with a behavioral change program following the steps suggested by Doug McKenzie-Mohr [1]. The pilot was launched with a group of nine volunteers who live in the building. Hot water consumption data was analyzed before and after the deployment of the strategy. There is not enough information to observe statistical evidence of a reduction in hot water consumption due to high variability in the after-deployment dataset. An extension of the after-deployment stage is suggested to overcome this lack of evidence. Nevertheless, participants agreed that the improvement in availability of consumption information from this pilot was useful to them in regards to understanding their hot water usage and ultimately, this could lead to a reduction in consumption.
