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 heat quantity to total the usage of energy using different units, and then dividing that total value by the total floor area of each campus.
2 Results for June
Except for Shiba-Kyoritsu Campus, which saw a 5% decrease compared to FY2024, energy consumption increased compared to FY2024, with four campuses other than Shinanomachi Campus showing a significant increase.
(1) Comparison with FY2024 (Energy consumption intensity in parentheses)
Mita Campus: 107% (61MJ/m2 )
Hiyoshi Campus: 106% (75MJ/m2 )
Yagami Campus: 110% (188MJ/m2 )
Shonan Fujisawa Campus (SFC): 114% (73MJ/m2 )
Shiba-Kyoritsu Campus: 95% (143MJ/m2 )
Shinanomachi Campus: 101% (240MJ/m2 )
(2) Factor Analysis
The outside air temperature (Tokyo), which is closely related to energy consumption, was 1.6°C higher on monthly average than the previous year, leading to a significant increase in cooling demand. As a result, energy consumption increased, causing energy consumption intensity to rise at campuses other than Shiba-Kyoritsu. Additionally, the fact that cooling operations were conducted in early June—which until last year was considered an intermediate period (when heating and cooling operations are generally stopped)—is also thought to have had an impact. For Shiba-Kyoritsu Campus, where energy consumption intensity was significantly reduced, the effects of switching lighting fixtures to LEDs and adjusting the air supply volume of outdoor air handling units are considered to have been significant.
