1 Energy Conservation Goals
Reduce energy consumption intensity by 2% or more compared to FY2024 for each campus unit.
*1 Energy Consumption Intensity
A numerical value calculated by converting each type of energy (electricity, gas, etc.) into its caloric equivalent to total the usage of different units, and then dividing that total by the total floor area of each campus.
2 September Results
Five campuses, excluding Yagami Campus and Shiba-Kyoritsu Campus, showed a decrease. Three campuses—Mita Campus, Hiyoshi Campus, and Shinanomachi Campus—achieved reductions exceeding the energy conservation goals.
(1) Comparison with FY2024 (Energy consumption intensity in parentheses)
Mita Campus: 92% (60MJ/m2 )
Hiyoshi Campus: 98% (76MJ/m2 )
Yagami Campus: 100% (199MJ/m2 )
Shonan Fujisawa Campus (SFC): 99% (72MJ/m2 )
Shiba-Kyoritsu Campus: 104% (171MJ/m2 )
Shinanomachi Campus: 94% (273MJ/m2 )
(2) Factor Analysis
The outside air temperature (Tokyo), which is closely related to energy consumption, was 0.1°C lower than the previous year, while there were three more extremely hot days. Based on this, cooling demand is considered equivalent to last year. However, energy consumption intensity is thought to have decreased due to the effects of measures such as operational improvements to the CGS at Mita Campus, operational improvements like locking empty classrooms at Hiyoshi Campus, and maintenance of heat source equipment at Shinanomachi Campus. Meanwhile, at Shiba-Kyoritsu Campus, which saw a 4% increase, energy consumption intensity rose due to increased use of air conditioning and the installation of new experimental equipment.
