TOKYO, February 13, 2019 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed a simulation technology for predicting energy consumption and comfort levels to operate net zero energy buildings (ZEBs). The new technology helps building energy managers easily and efficiently to determine in advance the ideal settings for balancing energy savings and comfort levels in ZEBs.

Overview of simulation technology for ZEB operation

Key Features

Highly accurate prediction of energy savings and comfort levels based on simulations
Simulation data is created for each building based on building information modeling (BIM) data, which includes information on the building itself and equipment installed in the building. The simulation also includes weather information and equipment schedules and settings, which further enhances the simulation's accuracy in predicting energy savings. The technology also predicts comfort levels in terms of temperature, humidity, wind speed and so on.
Operating plans based on simulations enable building energy managers to work efficiently
Simulations enable the building energy manager to analyze energy consumption while comparing the building's design values for floor/room usage, equipment types, etc. against the simulation's predicted values. Through this process, the manager can easily identify any large difference between design and predicted values. To correct for such differences, the manager can first execute a simulation using new settings for air conditioners, lights and other equipment to see if these changes bring the predicted values acceptably close to the design values. Simulations also can be used to predict comfort levels and balance them with energy savings. Moreover, the ability to determine proper settings before actually resetting equipment helps to reduce the building energy manager's workload. Further, once the settings are actually changed, conditions can easily be confirmed using the system's Energy Performance Screen and Three-dimensional Temperature Distribution Screen.
