National Chin-Yi University of Technology

Short, Middle, and Long-Range Energy Saving Plan

I. The overall objective of plan execution

                       i.The overall energy saving goal: The base period of the plan started in 2018. The school aims to increase overall electricity consumption efficiency by 10% by 2023.

                      ii.The school’s electricity saving goal (from 2020 to 2023): A year is used as the base period unit. the electricity saving goal is no EUI growth compared to the base year.

                 iii.The statistics of school energy consumption (electricity and water):

V. Plan stages and schedules

This plan is divided into three stages: short range, middle range, and long range. The short range goes from 2018 to 2021; the middle range goes from 2022 to 2024; and the long range goes from 2025 to 2027.

               i. Short-range plan (2018-2021):

(1) Saving Energy:

1. Divide the responsibility of areas to implement electricity saving measures. Each unit should divide the responsibility of areas and assign people to be in charge of the use of air conditioners and lighting. Such individuals shall be responsible for the temperature control of air conditioners and monitoring the switching on and off the lighting in their designated area. Oil saving shall be monitored by a particular executive.

2. When making a purchase, preference must be given to electronic and water supply equipment, appliances, and other office products with an energy-saving label, Green Mark, or water efficiency label.

3. New, additional, rebuilt, or modified construction works should adapt green building plans and designs and take energy saving into consideration. The installation of solar energy generation equipment is a priority.

(2) Clothing

During summer, wear light, casual clothes. No suits or ties shall be required except for special occasions, such as inauguration ceremonies, the reception of foreign guests with international etiquette, award ceremonies, international conferences, banquets, etc.; otherwise, do not wear a suit or tie and opt for lighter clothes instead.

(3) Air conditioning

1. Divide the responsibility of areas to manage and control the temperature of offices, conference rooms, and classrooms. Set an appropriate temperature (26~28℃) for these spaces, and use electric fans if necessary.

2. When the air conditioner is on, doors and windows have to be closed to keep the hot air outside from entering and to prevent letting out the cool air inside.

3. Clean and wash the air filters of window-type or packaged air conditioners and the central air conditioning system every month. Clean the cooling tower of the central air conditioning system every 3 months.

4. Ask air conditioning maintenance vendor or technician to regularly check the coolant amount of the air conditioning unit. If the coolant is insufficient, please refill immediately to maintain the central air conditioning unit’s efficiency.

(4) Lighting:

1. Review and evaluate whether environmental illumination is appropriate and make improvements according to CNS illumination standards.

2. Where no safety concern is present, in places with low lighting demands, such as hallways and corridors, set the lights on at intervals, reduce the number of fluorescent tubes, and use sensors to detect human motions to turn the lights on and off.

3. Adjust lighting facilities to the top of the desks, and add independent power switches. Turn off lights when leaving a space.

(5) Elevators:

1. Climb stairs when you’re going fewer than three floors and don’t take the elevator.

2. When a building has two elevators, they should be set to stop at alternating floors (one stops at odd-numbered floors and the other stops at even-numbered floors). If you take an elevator that does not stop at the floor you would like to go to, use the stairs to go the remaining floor.

3. When installing a new elevator, or the old one is replaced, variable voltage and variable frequency (VVVF) elevators should be adopted.

(6) Power system:

1. The site in which the voltage transformer is placed is required to have good ventilation. When necessary, install additional fans or air conditioners to dissipate heat.

2. The units that make contract capacity with Taiwan Power Company should regularly review the reasonable contract capacity value and power factor (which should reach over 99%) to reduce electricity costs.

3. Establish an energy & resource management system for the school.

(7) Office machines and computer facilities room:

1. Set machine and equipment to energy saving mode. When the machine stops working for 5 to 10 minutes, it will automatically enter a low-power energy consuming sleep mode.

2. The entrance temperature of computer facilities rooms should be kept between 20 and 25℃, and its relative humidity should be kept between 40 and 55%.

3. New, additional, rebuilt, or modified construction works should adapt energy saving plans and designs. The installation of solar energy generation equipment is a priority.

(8) Saving water:

1. Facilities using water such as faucets and toilets should have a water efficiency label. Also regularly check for and repair any water leakages.

2. New, rebuilt, or extension buildings should comply with the water resources index specifications of the Green Building Labeling System. The harvesting and utilization of rainwater and the recycling and utilization of domestic wastewater constructions and measures are priorities.

3. New or extension offices or offices with overall modifications should adapt a water saving and dual distribution system (which divides the pipelines for tap water and those for domestic waste water) plan and design.

            ii. Middle-range plan (2022-2024)

(1) Replace old air conditioners: Replace old air conditioners that have been used for more than nine years.

(2) Establish a class schedule management system and integrate it with classroom air conditioning and lighting management.

(3) The establishment of a user charge system: establish an air-conditioning accounting system for general classrooms and student dormitories.

            iii. Long-range plan (2025-2027)

(1) Solar power generation system of buildings: Install a solar power generation system to increase the proportion of green energy.

(2) Establish an energy consumption monitoring system: Include window types and separate air conditioners of the entire school in the energy management system to monitor the energy consumption situation of each room.

                (3) Use the school's energy resource monitoring system to manage the water and electricity consumption data of each building and then duly improve it by analyzing the energy consumption of the entire school.
