Saving energy approaches
Energy Awareness Posters
At a campus, education/research activities and other routine daily tasks consume considerable amount of energy and emit CO2. At Hokkaido University, we aim for campuses with low environmental impact and promote energy saving approaches. In 2017, based on Sustainable Campus Action Plan2016, posters to promote energy saving had been prepared. Their contents are made to conform to the fact at Hokkaido University, using data from facility information management system and measurement from various equipments taken between FY2015 and FY2016. There are also stickers showing actual measurement data.
For details, please contact: Sustainable Campus Management Office (osc*osc.hokudai.ac.jp) (please replace * with @).
Thermostat Standards: Set the heater to 20℃ in the winter, & the AC to 28℃ in the summer.
By changing the setting of air conditioners from 21℃ to 20℃ in winter and 27℃ to 28℃ in summer and reducing hours of use by one hour every day, we estimate roughly 2,500 yen to save annually for each machine. With monthly cleaning of the filter, this will further save approximately 560 yen per year. Let us utilize lap blanket in winter and half-sleeve shirts in summer to reduce the use of air conditioning as much as possible.
Set the warm water and seats to “low”.
Let us make sure that temperature settings of warm water and toilet seats are “low & low.” Compared to “high & low” the electricity consumption can be more than halved, and saves roughly 3,000 yen per year for each machine. Across the entire Hokkaido University, we estimate approximately 4 million yen saving annually.
Let them sleep when not needed.
Aren’t you powering up your computer excessively? Electricity consumption in Sleep Mode is roughly 10% of full operating mode. By diligently using Sleep Mode, roughly 480 yen can be saved per machine annually, and we estimate this will result in 6.7 million yen saving across the entire Hokkaido University. If “no computer use needed today,” let us do without turning it up.
Switch off the lights when leaving.
Diligently turning off light is quite effective for saving energy. Based on actual measurement survey at Faculty of Advanced Life Science (Northern Campus Area Research Building No. 2), electricity consumption had gone down 13% by turning out all lights in the entire building during lunch break.
If lights are turned off for one hour every day across the entire university, approximately 1.4 million yen can be saved annually.
Let them sleep in 15 minutes at the longest.
Photocopiers consume electricity even in standby mode. Taking electricity consumption during copying as 100%, it is roughly 77% in standby and 30% in sleep mode. By enforcing “put to sleep mode after use”, approximately 2,760 yen can be saved per year for each machine, and we estimate approximately 1.6 million yen saving for the entire Hokkaido University. Please check your setting and change it right now if it is longer than 15 minutes.
80 ℃ is hot enough for keeping.
Are you sure the temperature setting for keeping water warm is appropriate? If we say electricity consumption at 98℃ setting as 100%, it goes down to 30% at 90℃, and 10% at 80℃which mean 90％ cutting down. Changing the setting to 80℃ is expected to save approximately 1,640 yen per year for each 4ℓpot, totaling to roughly 4.9 million yen per year for the entire Hokkaido University.

Result of Energy Saving Actions
“Setsuden Follow up”, the Energy Saving Actions is now available HERE. (for internal use only, in Japanese)
Electric Power Demand Monitoring System
We implement visualization of electricity usage (Sapporo Campus) in our website. When it is determined that the maximum electricity consumption would exceed the target upper limit, warning emails are sent to Sustainable Campus Promoters, staff in charge of energy consumption at each departments. When they receive the alert, they would notify faculty members within the respective departments and ensure “electricity saving methods” are implemented.
Energy Consumption Visualization – Energy Management
Hokkaido University has been trying to minimize the environmental load. To raise awareness regarding energy conservation, energy consumption dashboard is now available on our website (click the picture below). It shows bar graphs on consumption amount of electricity, water supply / sewerage, and gas, as well as waste amount on grouped departments on campus. In regards to each department’s information, refer to “Energy Management System” in Facilities Information Management System.
We hope the information provided will be used effectively to lead to engage energy conservation and reducing costs.

Sustainable Campus Cafes
Sustainable Campus Cafes have been held as opportunities that Environmental Impact Reduction Promoters and their assistants, faculty members and students from various departments exchange opinions. With unique manner than normal Environmental Impact Reduction Promotion Meetings, participants can open up to each other in a relaxed atmosphere and draw out frank opinions and new perspectives. New challenges for “developing a sustainable campus” are extracted/analyzed from within that and lead us to the next actions.
“Hokkaido University now” “What is Hokkaido University’’s characteristics?” “Futures of Hokkaido University” 4 February 2014

“How should it be? Pictures of the areas around Administration Bureau in twenty years” 26 August 2015
To make a preliminary design of a building and the surrounding in corporation with users from respective departments, it requires new approach in facilities/environment management method. It was a workshop to bring out how. Specifically referring to renovation plan and progress of three buildings of Graduate School of Engineering, we discussed about the area around Administration Bureau and the neighborhood outside the Main and South Gates, how should the area be? What about the organizational structure to accomplish? It was a new attempt as a workshop among professionals from professors of Task Forces under Executive Office for Campus and Environment Planning, staff from Facilities Department and Sustainable Campus Management Office.
New Campus Master Plan Workshop
What should be the contents of the plan that follows “Campus Master Plan 96” and “Campus Master Plan 2006”? Faculty members and students who are not directly involved with drawing up the plan joined the workshop in order to reflect idea of their own or of those around them.

Waste segregation and their collection methods
How would you dispose empty container of lunch? Is there any leftover in the container? How would you dispose then? Paper files can become a resource if fasteners are removed. There are quite a few things that can become resources by making a little extra effort. What about gloves used in an experiment? A styrene foam box that had contained a machine?
Candle night in Hokkaido University
“Let’s turn off the lights from 8pm to 10pm on the night of summer solstice and spend a slow night.”
Taking a hint from “Voluntary Blackout movement” of 2001 in Canada, this had spread across the entire country as “Candle Night for 1,000,000 persons” in 2003, and “Sapporo Candle Night” executive committee was formed in 2004. Hokkaido University supported the aim of this movement and has been participating in it since 2011. Student environmental organization SCSD* (the Student Council for Sustainable Development in Hokkaido University), Sustainable Campus Management Office and Facility Department work together on this, with helps from community members of the areas around the university and members of student clubs.
SCSD was established in April 2010.
Hokkaido University Team (8 members) that attended an international students conference hosted by Copenhagen University and Yale University as an associated event to COP 15 of December 2009 was asked to realize the ideas for bringing forth Sustainable Campus that were proposed in the conference at their own universities. SCSD was established as a student activity organization for realizing Sustainable Campus in our university, with conference attendee members playing the central roles. Its activities started with 26 members, made up from graduate students of Public Policy School and Graduate School of Environmental Science, as well as overseas students studying at Hokkaido University.
Accepting Energy-saving proposals related to educational and research activities
Sustainable Campus Management Office is accepting energy-saving proposals related to educational and research activities. Based on “the Action Plan for building a sustainable campus 2016”, which states that energy consumption needs to be further streamlined and that the formation of sustainable campus is a required issue as a part of the facilities management reform, various proposals are all welcome.
The purpose is to provide financial support for energy-saving measures implemented in connection with education and research, and for surveys and research that contribute to energy-saving on our campus. With this, further reduction of environmental load of our university is to be promoted.
* Formulation of the Action Plan 2016 for Building a Sustainable Campus (SCAP 2016) has been set to reduce capacity unit of energy consumption of FY 2021 (total of Sapporo campus and Hakodate campus) up to 2.03GJ/㎡.
