Request for Cooperation: Energy-Saving Measures for Summer 2017

Transcription

1 DATE: June 16, 2017 TO: Institute Members FROM: Shinji Ando, Head of the Energy Conservation Section Request for Cooperation: Energy-Saving Measures for Summer 2017 This is a letter requesting all members of Tokyo Institute of Technology to cooperate in an Institute-wide effort to save energy during the coming summer months. According to the Electricity Supply-Demand Review Meeting on May 12, the government has decided not to make a nationwide request to save energy using a numerical target this year. The Institute remains committed to saving electricity by implementing practicable measures, and by avoiding to as great an extent as possible any disruption to education and research activities. Members of the Institute are requested to consult the Guidelines for Energy Efficiency and Conservation during the Summer Season for details on the energy-saving efforts planned for this summer. Information regarding on-campus electricity use is also available at the Energy Conservation Section s website. Members should check the power consumption reports of previous years and make use of the monitoring system that displays real-time demand in order to control and save electricity. The continued support of Institute members regarding this matter is greatly appreciated. Period Saturday, July 1, 2017 Saturday, September 30, 2017 Targets Reduction in peak power demand (kw) and annual power consumption (kwh) Refer to the Guidelines for Energy Efficiency and Conservation during the Summer Season (AY ) for details. Attached documents Attachment 1: Guidelines for Energy Efficiency and Conservation during the Summer Season (AY ) Attachment 2: Power Alerts and Required Actions Document Attachment 3: Energy Efficiency and Conservation Manual Attachment 4: Energy-Saving Checklist Attachment 5: Energy-Saving Posters

2 Attachment 1 June 16, 2017 Guidelines for Energy Efficiency and Conservation during the Summer Season (AY ) The two aims 1. Reduction in peak power demand 2. Reduction in power consumption Strategy Monitoring of power usage Period during which the policy and measures take effect Saturday, July 1, 2017 Saturday, September 30, Purpose The Institute s policy on energy-saving efforts during the summer of 2017 is to implement practicable measures that will cause minimum disruption to its education and research activities. In the current economic climate, where government funding to national university corporations for management expenses is being cut back and electricity expenses are on the rise due to hikes in crude oil prices and renewable energy surcharges, careful management of electricity use is essential to protect the Institute s finances. In addition, cutting down on electricity helps Tokyo Tech achieve its goal and obligation of reducing the amount of greenhouse gases it emits. Under the Tokyo Climate Change Strategy, the Institute is required to reduce its annual CO2 emissions by an average of 17% from the base year emission level during the 5-year period of 2015 to Targets 2.1 Peak power demand targets for the summer season Targets are set to the lower figure of either the current contracted power or the peak power demand recorded in summer Ookayama Campus: 9,288 kw (current contracted power) Suzukakedai Campus: 5,780 kw (summer 2016 performance) Tamachi Campus (affiliated high school): 167 kw (summer 2016 performance) Tamachi Campus (Campus Innovation Center): 283 kw (summer 2016 performance) 2.2 Annual power consumption targets 1

3 Targets are set to the lowest figure recorded since the Great East Japan Earthquake. Ookayama Campus: 43, kwh (FY 2011 performance) Suzukakedai Campus: 28, kwh (FY 2016 performance) Tamachi Campus (affiliated high school): kwh (FY 2015 performance) Tamachi Campus (Campus Innovation Center): kwh (FY 2016 performance) 2.3 Power consumption targets for the summer season (July September) Targets for Ookayama and Tamachi Campuses are set to the lowest power consumption figure recorded since the Great East Japan Earthquake. By reaching these targets, Ookayama Campus, Tokyo Tech High School of Science and Technology, and the Campus Innovation Center will reduce their power consumption by 1.2%, 0.8 %, and 0.7%, respectively, from the figures of FY The target for Suzukakedai Campus is set to the figure recorded in FY Ookayama Campus: 8, kwh (summer 2011 performance) Suzukakedai Campus: 7, kwh (summer 2016 performance) Tamachi Campus (affiliated high school): kwh (summer 2011 performance) Tamachi Campus (Campus Innovation Center): kwh (summer 2011 performance) Note: The target figure for Ookayama Campus excludes power consumption at the Global Scientific Information and Computing Center (GSIC) and Tokyo Tech Front. 3. Policies 3.1 Real-time monitoring of electricity usage Efforts will be made by Institute members to control air conditioning and operate laboratory equipment wisely by making use of the Institute s real-time monitoring system that records demand and power consumption of campus buildings at each floor level. Past data concerning campus building power consumption, which is available at the Energy Conservation Section s website, is also to be used as reference. The Energy Conservation Section website is at the following URL. Note: The power consumption for the first two months of FY 2017 is down by 3.2% from the previous year at Ookayama Campus, down by 0.4% at Suzukakedai Campus, up by 1.2% at Tamachi Campus, and down by 8.2% at the Campus Innovation Center. 3.2 Adherence to Cool Biz Smart Casual Campaign Institute members are encouraged to work in light clothing (polo shirts, no ties, etc.) so that air conditioners need not be set excessively low to help suppress peak power demand and power consumption. 3.3 Power alerts 2

4 When power alerts are issued or during tight electricity supply-demand situations, Institute members must turn off lights in their laboratories and offices. Air conditioners must be switched off unless it affects ongoing experiments or Institute operations. Electrical appliances that do not impact ongoing experiments must also be switched off. For more information, refer to the Power Alerts and Required Actions document (Attachment 2). 4. Measures 4.1 Lighting Switch off lights during lunch breaks and when rooms are unoccupied. Use partial lighting in rooms. Turn off lights in areas where there is sufficient daylight, such as areas close to windows. If only a portion of a room is used, turn on the lights only in that area. The number of lights turned on should be reduced to 50% (adjustments may be made to take safety as well as work and study conditions into account). 4.2 Computers Shut down computers or use sleep mode when not in use. 4.3 Air conditioners Temperature setting should be 28 C when in use. Use air circulators and fans to circulate air and to even out the temperature within rooms. Regularly clean air conditioner filters. 4.4 Ventilation Avoid wasting energy through excessive ventilation. Make a habit of turning on ventilators, fans, total heat exchangers, and fume hoods on an as-needed basis, always turning them off after use. Reduce the number of times a room is ventilated when the number of occupants is small. 4.5 Elevators Tokyo Tech encourages its members to follow the "Two up, three down" campaign (the use of stairs instead of elevators when traveling up two floors or less, and down three floors or less). 4.6 Amenities The use of hot water dispensers and coffee makers that consume energy to keep water or coffee hot at all times is strongly discouraged. Use insulated carafes instead. Electric water heaters, other than those required for experimental purposes, must not be used. Seat-warming and water-heating functions of electric toilets must be turned off. 4.7 Education and research equipment Review the optimal temperature settings of air conditioners in server rooms. Reduce the number of refrigerators and freezers through consolidation and shared use. Review 3

5 their optimal temperature settings. Cut down on the number of appliances that are kept running for 24 hours a day through consolidation and shared use. Consider replacing old appliances with more energy-efficient types. Unplug appliances lying idle. Shift the operation of appliances from daytime peak hours (13:00 to 17:00) to early morning hours and night times whenever possible. 4.8 Promotion of energy-saving measures Undergo inspections using the Energy-Saving Checklist (Attachment 4) Display energy-saving posters (Attachment 5) Note: Efforts to save electricity must not compromise the Institute's mission in education and research, nor should it put at risk the health and safety of Institute members. 4
