In an office building in the US the office equipment uses about 7% of the total electricity use. Even though this is a low number, there is still a reason to save more energy, especially since one third of the energy savings are lost when power management is not enabled. The core in the project ”Power Management Controls” is to develop a voluntary standard, The User Interface Standard, that manufacturers of office equipment can use as a reference when they develop new equipment and design new interfaces. The interface is an important part of the use of power management and doing this should increase the use of power management and save more energy. The interfaces are ofter hidden or inconsistent and confusing, which makes it harder for the user to understand power management. A more consistent interface makes it easier for the user to understand the meaning of an interface and power management itself The standard consists of six different parts, which describe what can be done to achieve a consistent interface. The standard also describes the part of the project called Dynamic Behavior. This part is concentrating on the interfaces and the behavior of the device over time, which is important for the user to understand. The purpose of this degree project is to study and participate in the project ”Power Management Controls”, and to understand what is being done to save more energy.
