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 the usage of different energy sources (electricity, gas, etc.) into heat equivalents to total them, and then dividing that total by the total floor area of each campus.
2 Results for August
Five campuses, excluding Shiba-Kyoritsu Campus which remained at the same level as the previous year, showed a decrease. Four campuses—Mita Campus, Hiyoshi Campus, Yagami Campus, and Shinanomachi—achieved reductions exceeding the energy conservation goals.
(1) Comparison with FY2024 (Energy consumption intensity in parentheses)
Mita Campus: 92% (65MJ/m2 )
Hiyoshi Campus: 96% (80MJ/m2 )
Yagami Campus: 96% (204MJ/m2 )
Shonan Fujisawa Campus (SFC): 99% (74MJ/m2 )
Shiba-Kyoritsu Campus: 100% (167MJ/m2 )
Shinanomachi Campus: 93% (291MJ/m2 )
(2) Factor Analysis
The outside air temperature (Tokyo), which is closely related to energy consumption, was high at +0.6°C compared to the previous year. Additionally, there were 11 more extremely hot days, suggesting that cooling demand was higher than last year. However, energy consumption intensity is thought to have decreased significantly due to the effects of measures implemented at each campus: operational improvements to the CGS at Mita Campus, operational improvements to total heat exchangers including CO2 sensor control at Hiyoshi Campus, LED lighting retrofits at Yagami Campus, and maintenance of heat source equipment at Shinanomachi Campus.
