1. Energy Conservation Target
To reduce the energy consumption intensity at each campus by 2% or more compared to FY2024.
*1 Energy consumption intensity
This figure is calculated by converting various energy sources (e.g., electricity, gas) into their calorific values, summing these values, and then dividing the total by the total floor area of each campus.
2. May Results
All campuses showed a decrease compared to the previous year. Five campuses, excluding Mita Campus, achieved the target of a 2% or more reduction.
(1) Comparison with FY2024 (figures in parentheses indicate energy consumption intensity)
Mita Campus: 99% (47MJ/m 2 )
Hiyoshi Campus: 94% (54MJ/m 2 )
Yagami Campus: 97% (145MJ/m 2 )
Shonan Fujisawa Campus (SFC): 97% (53MJ/m 2 )
Shiba-Kyoritsu Campus: 92% (123MJ/m 2 )
Shinanomachi Campus: 92% (192MJ/m 2 )
(2) Factor Analysis
The outside air temperature in Tokyo, which is closely related to energy consumption, tended to be lower than in the previous year. It is believed that this led to a reduced cooling load, contributing to the decrease in energy use. Furthermore, significant reductions in energy consumption intensity were achieved at several campuses. At Shinanomachi Campus, which saw a large reduction, this was due to operational improvements of its outdoor air handling units. At Shiba-Kyoritsu Campus, the reduction resulted from retrofitting lighting fixtures to LEDs. At Hiyoshi Campus, the reduction was achieved through a combination of retrofitting lighting fixtures to LEDs and operational improvements to its air conditioning and ventilation systems.
