1 Energy Conservation Goals
Reduce energy consumption intensity by 2% or more compared to FY2025 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 Results for May
Mita Campus and Shonan Fujisawa Campus (SFC) achieved reductions exceeding the energy conservation goals. On the other hand, Hiyoshi Campus, Shiba-Kyoritsu Campus, and Shinanomachi Campus saw increases, while Yagami Campus remained at the same level as the previous year.
(1) Comparison with FY2025 (Parentheses indicate energy consumption intensity)
Mita Campus: 94% (44MJ/m2)
Hiyoshi Campus: 101% (54MJ/m2)
Yagami Campus: 100% (146MJ/m2)
Shonan Fujisawa Campus (SFC): 97% (51MJ/m2)
Shiba-Kyoritsu Campus: 101% (125MJ/m2)
Shinanomachi Campus: 103% (197MJ/m2)
(2) Factor Analysis
The average outdoor temperature in Tokyo was 1.3°C higher than the previous year, and in the latter half of May, there were several days where the maximum temperature reached around 30°C. This led to an increase in cooling demand, resulting in higher usage at Hiyoshi Campus, Shiba-Kyoritsu Campus, and Shinanomachi Campus. Conversely, the reduction in energy consumption intensity at Mita Campus is attributed to LED lighting retrofits, and at Shonan Fujisawa Campus (SFC), to power generation from solar power systems.
