Urban Energy Systems Lab
Machine-translated · View original
The lab models urban energy demand to explore what a sustainable city could look like.

AboutAbout the lab
Rethinking how cities work, starting from the demand side of energy.
The Shimoda Lab studies how energy is used in cities, using simulation to evaluate and optimize it.
The lab believes that the root of energy problems lies on the demand side. It treats energy demand as an area-wide system across a city and analyzes and evaluates both the whole and its individual elements.
Through modeling and forecasting energy demand, mainly in the residential and commercial sector, evaluating and developing technologies for adjusting the thermal environment, and planning methods for energy-efficient cities, the lab pursues what a sustainable urban energy system should be.
The lab carries out interdisciplinary education and research spanning building environmental engineering, energy systems engineering, thermal engineering, power distribution engineering, urban planning, and statistics.
Key terms
- Residential and commercial sector
- A category that combines the residential sector and the commercial sector, that is, the energy used in buildings.
- Final energy demand
- Demand on the user side, defined by which devices use energy and for what purposes.
- Smart grid
- A digitally enabled power system that collects and uses information on the behavior of both the supply side and the demand side.
ResearchResearch themes
This lab focuses on which devices use energy, and for what purposes, at the scale of cities and regions, aiming to understand demand in detail. It works on modeling and forecasting energy demand in the residential and commercial sector, smart grids, and performance evaluation of thermal energy systems, and explores desirable urban energy systems that are coordinated with energy supply.
*Illustrative imageModels of final energy demand in the residential and commercial sector
The lab develops simulation models that estimate energy demand in the residential sector and the commercial sector. Taking into account weather, lifestyles, occupant behavior, and the specifications of buildings and equipment, it quantifies the effect of climate change countermeasures on reducing carbon dioxide emissions.
*Illustrative imageSmart grids that make use of electricity demand
The lab studies how to manage electricity demand appropriately to improve overall performance in power systems where large amounts of renewable energy such as solar power are connected to the grid. It takes part in a JST CREST project, working jointly with laboratories and institutes in electrical engineering and meteorology.
*Illustrative imagePlanning methods for smart communities
The lab studies evaluation of the energy balance of cities and districts, setting of energy targets in development projects, and simulations that predict energy performance. It participates in joint research of the IEA (International Energy Agency) and has also continued an initiative that treats the Osaka University campus as a single city.
*Illustrative imagePerformance evaluation of thermal energy systems
The supply of heat for cooling, heating, and hot water accounts for a large share of the energy flow in a city. The lab evaluates district heating and cooling, cogeneration, heat pumps, and similar systems, including through analysis of existing buildings, and studies the optimal design of new heat supply systems.
