Business users

User C is an executive at a manufacturing company. He is interested in monitoring the energy consumption of his office building, warehouse, and manufacturing plant. He seeks to minimize overall energy costs and to make his facility more "green." Thus, he would like to view high-level reports about the total energy consumption in each area of the facility (office/warehouse/plant) and associated monetary costs.

He is familiar with energy conservation and reuse technologies, some of which are currently implemented in his facility. He would like the ability to resell any excess reclaimed energy back to the power company.

The warehouse and plant areas tend to be noisy, dirty, and dangerous. He would prefer to use the application from the office building, so the ability to manage devices remotely is important.

The facility contains many devices of different types--some standard (such as computers) and others nonstandard (such as manufacturing equipment). Therefore, the application should scale well to accommodate large numbers and types of devices. User C would like to be able to define custom groupings for the devices, organizing them by type or location, for instance.

He would share these energy-management tasks with a small number of other employees. The application should provide a secure interface for allowing access to multiple users.

Both User C and the other employees who would use the application have extensive computer experience, but some have limited experience with touchscreen mobile devices. User C would expect to offer some training to his employees before having them use the application.To accommodate business users, features have to be scalable to larger numbers and different types of devices
