An energy engineering lab for a decarbonized society, linking electrical, mechanical, and thermal energy.

AboutAbout the lab
Creating a brighter future with environmental energy technology.
Saito Lab researches energy conversion engineering spanning electrical, mechanical dynamics, and thermal energy systems.
Using "circuit theory," which can be applied in common to analyses in different engineering fields, the lab has built a unified analytical theory for energy systems.
Based on this theory, the lab works on developing thermal energy equipment such as heat pumps and on building a decarbonized society that makes use of hydrogen energy and renewable energy.
Key terms
- Circuit theory
- A theory that uses the concepts of electrical circuits to represent the flow of energy in a unified way
- Heat pump
- A device that collects and uses heat from sources such as the air with little energy (used in air conditioners and water heaters)
- Decarbonized society
- A society that has brought emissions of greenhouse gases such as carbon dioxide close to net zero
