Saving electrical energy is an important task because the energy consumption is increasing but the resources are limited. Analyzing the electrical energy usage pattern of an institute is important to find a method to save electricity because the method to save electricity can be different depending on the usage pattern. Visualization is a good method to analyze the usage pattern and to present the analysis result to the public. In this paper, we analyze and visualize the electric energy consumption of all laboratories in a building. We also develop a system that automatically processes the electrical energy consumption and visualizes it in real time.
