Awareness of resource consumption in the home is a key part of reducing our ecological footprint yet lack of appropriate understanding and motivation often deters residents from behaviour change. The coming deployment of smart metering technologies, the increasing practicality of embedded devices, and the widespread use of Internet and mobile tools offer new opportunities for “greener” residents. We report on the design and implementation of a holistic interactive system that supports residents in awareness of resource use and facilitates efficient control of house systems to encourage conservation in daily activities. Initial response from two high-profile deployments in unique homes indicates this approach has great potential in engaging residents in sustainable living, but presents many challenges in how technology is integrated into the home environment.
