Energy-efficient user interaction with an off-grid building

This paper describes the design of energy-efficient wide spectrum mechanisms and protocols to capture context information and employ actuation to close the feedback loop. The project described in this article focuses on harvesting energy from the environment through as many ways as possible, and efficiently using the harvested energy in off-grid buildings, dynamically adapting the consumption to currently available energy levels. The main energy sources to be used for harvesting are: solar energy, wind energy, wasted wireless communication energy and hydro energy. Through its web and Android interfaces, the project offers functionalities such as analyzing energy harvesting efficiency, monitoring building-wide energy consumption, setting up profiles and managing consumers individually.
