Akashi Lab
Machine-translated · View original
A building environment lab that uses the power of data to manage energy in buildings and communities intelligently.

AboutAbout the lab
Upgrading building environments and energy.
Akashi Lab researches how to make the energy systems used in buildings and communities energy-efficient and decarbonized.
A distinctive feature of the lab is its use of information technologies, such as large volumes of sensor data (big data) and machine learning.
The lab also works on the use of renewable energy and on creating healthy, comfortable indoor thermal and air environments.
Together with Taniguchi Lab and Miyata Lab, the lab forms the "Building GX (Green Transformation) Research Group" and carries out joint activities.
Key terms
- Big data
- Large volumes of diverse data collected from sensors and other sources. It can capture even fine-grained changes.
- Machine learning
- A technology in which computers learn rules from large amounts of data and use them for prediction and decision-making.
- Non-energy benefits
- Positive effects of energy-saving measures other than energy savings, such as improved health and comfort.

ResearchResearch themes
The lab studies energy systems in buildings and communities, focusing on efficient operation that leads to energy savings and decarbonization, the use of renewable energy, and the creation of healthy, comfortable thermal and air environments. Its research and development centers on making use of big data and information technology.
*Illustrative imageSmart Energy Management
The lab uses real-time sensor data and machine learning to operate energy systems with unprecedented efficiency. It also develops the simulations that underpin this work.
*Illustrative imageHuman-Centered Indoor Environments
The lab measures and uses detailed data on people, the environment, systems, and spaces to develop environmental control that improves each individual's health and comfort, as well as mechanisms that encourage behavior change.
*Illustrative imageRenewable Energy Use and Energy Coordination
The lab considers ways to coordinate energy between buildings and electricity and heat supply networks, and between one building and another. It demonstrates the effects quantitatively and explores pathways for using renewable energy.
*Illustrative imageMeasuring the Effects of Energy-Saving Measures
For energy-saving and decarbonization measures, the lab also clarifies benefits beyond energy savings (non-energy benefits), and considers how to design such measures and how to make the case for them to owners and users.
