Context

Smart cities depend on an electricity grid to ensure resilient delivery of energy to supply their main functions, present opportunities for savings, improve efficiency and so on. Among other things, a smart electricity grid

informs and educates users about their energy usage, costs and alternatives, to enable them to make decisions autonomously about how and

when to use electricity

Focus

• Non-residential buildings

• Building Energy Management System

• A platform that interfaces users with the grid and considers their needs, their living environments and energy prices to coordinate automatically the usage of appliances

Focus

• Simple unobtrusive sensors (e.g., electricity plugs, light sensors, movement sensors) to provide insights in the energy demands for the grid

• For instance, one can use live indoor data to match end-users energy consumption to the fluctuating supply of local energy sources by using automation (e.g., automated regulation of the heating system)
