In May 2019, Sustainable Campus Management Office accepted energy saving proposals related to educational and research activities ” . Based on “the Action Plan for building a sustainable campus 2016”, we aimed at improving the efficiency of energy consumption.
The following projects were adopted and implemented.
“Installing large size freezer to store the samples effectively and to save energy”
Field Science Center for Northern Biosphere, Prof. Tsutomu Hiura
(ref: Progress Report)
Faculty members of Field Science Center for Northern Biosphere and students of Forest Field Science, Graduate School of Environmental Science work frequently in the fields and handle large plants, soil and big wild animals. Consequently, they were facing storage space shortage issue. They had many freezers, however, the total capacity was small thus the storage for samples was beyond the limit. For this reason, the students had to drive to Tomakomai Research Forest or Nayoro North Management Office to store their samples. It caused time loss, expensive fuel cost and environmental burden. We installed a large freezer and the capacity was dramatically increased. Not only we no longer have to concern about those extra cost, but also both faculty members and students are satisfied with smooth in and out upon installing selves inside the freezer.
Reppled effect on research and education
• They used to use many freezers in labs, but as they use one common large freezer, they are now able to communicate mutually.
• As they observe the samples of others, they oftenly discuss their research contents.
• The new freezer creased new space and they use it for other work.
Environmental effect
The new freezer has content quantity of 21,108L, compared to 1,786L of 5 old freezers. The amount of electricity per capacity is 0.006kW for 9 days with the new freezer, with approximately a one-tenth decrease out of 0.051kW with the old ones.
【Before】small size freezers squeezing the lab space
【After】 now space effectively use
