Far Eastern Magazine / Editorial Room
Far EasTone Telecommunication establishes an environment and energy management system to exert industry influence from the point of view of telecommunication service life cycle and provide various available resources to customers, suppliers and contractors to mitigate climate change. The correct concept of using energy, so that every energy can play the greatest role.
In order to improve energy performance and reduce greenhouse gas emissions, Far EasTone Telecommunication takes core competence as its core competence, transforms information technology into an environmental friendly practical action. Through the Environment and Energy Management Committee, it carries out the energy flow review, analyses major energy consumption, and proposes countermeasures to reduce electricity consumption. It implements the energy management mechanism in every link, regardless of the base. The ventilation system of the platform, or the energy-saving competition in the market, every measure is implemented pragmatically. Among them, the innovative "Retired Cabinet Cleaning Plan" breaks through the long-standing energy-saving pain of telecommunications and information industry.
Equipment Replacement Base, Radio and TV University
Far EasTone Telecommunication bases are located all over the world. If each base station can reduce energy consumption, its overall benefit is absolutely considerable. According to the assessment of the Energy Bureau of the Ministry of Economy, air-conditioning can save about 6% of the air-conditioning power by raising the set temperature of air-conditioning by 1 C. Therefore, Far EasTone Telecommunication decided to start with the air-conditioning temperature of the base station.
After selecting the base station, the air-conditioning temperature is gradually raised from 26 to 28 degrees Celsius to check the operation status of the base station equipment, confirm that the network can provide normal service, then gradually raise the air-conditioning temperature from 28 degrees Celsius to 30 degrees Celsius, observe the measurement network status, confirm that it does not affect the quality, and finally complete the air-conditioning adjustment of all base stations.
The second measure is to install high-efficiency frequency conversion air conditioning instead of the original fixed-frequency separation air conditioning, hoping to reduce the power consumption of air conditioning without affecting the network services, so as to achieve the purpose of energy saving and cost saving of air conditioning. Because the variable frequency air conditioning is soft to start, it can reduce the problem of frequent start of compressor, and achieve the effect of saving electricity and energy. At the same time, the compressor has a small sound, which can take into account the good neighborliness and environmental friendliness. In addition, constant temperature and quick cooling are also the advantages of converted air conditioning. Far EasTone Telecommunication budgets every year to phase out old or faulty fixed-frequency air conditioners. According to the trial calculation of power consumption efficiency, the average group of air conditioners (2 units) can save 800 yuan (NT) per month.
In addition, after carefully assessing climate and environmental conditions, Far EasTone Telecommunication built out-of-platform air ventilation system, designed adjustable style grid air guide device, and guided the wind to the highest heat source according to the site environment, so as to improve heat dissipation efficiency. At the same time, the new ventilation system can also introduce outdoor cold air, and use pressure difference to discharge indoor hot air, instead of traditional cold air to reduce indoor temperature, so as to achieve the purpose of energy saving.
Moreover, Far EasTone Telecommunication also took the initiative to participate in the bidding of radio demand, in order to increase the temperature of ice water outlet, suspend some air conditioners and ensure good efficiency of air conditioning equipment, transfer electricity during the demand period and reduce peak power consumption. In 2017, the total restrained power consumption was 1,444 kW. Even general lighting equipment is included in the overall energy-saving plan of Far EasTone Telecommunication. For example, IDC is a rented room. When customers leave, they often neglect to turn off the lights at random. Far EasTone Telecommunication specially equips the lighting control equipment in the room. By using the central monitoring system, the flow of people is combined with the second-line lighting control. Once nobody is found in the room, it automatically closes the room. Area lighting. In addition, Far EasTone Telecommunication also regularly implements power system maintenance to ensure safety and normal; the basement parking lot public area fire protection and basic lighting are fully replaced with microwave induction LED lights, and in the roof illumination and infrared induction lighting, outdoor lighting is set according to season. With all-round efforts, the electricity saving rate of Far EasTone Telecommunication reached 7.82% in 2017. Compared with the previous year, the electricity consumption of Far EasTone Telecommunication decreased by about 3.77 million kilowatt-hours, equivalent to the carbon reduction of 5.1 Da'an Forest Park, and substantially reduced the electricity cost by about 12.32 million yuan (NT$).
Coincidentally, KGEx.com under Far EasTone Telecommunication has also improved its energy efficiency by improving various equipment, including: leading industries using magnetic levitation centrifuges with the highest air-conditioning efficiency and full-liquid screw machines with off-peak load operation and high sensible heat engine room air-conditioning box, cooling tower reducer motor with frequency conversion control, building cold and hot passages, and consolidation of engine room. And virtualize Server, clean up idle cabinets, UPS continuous power system replaced by high efficiency machines, and adjust the best capacity... And so on, to make a contribution to industrial energy conservation.
It is worth mentioning that Far EasTone Telecommunication's drastic consolidation of idle cabinets is the first inter-departmental joint cleaning of telecommunications and information rooms in the group, which can avoid the blind spot of single sector implementation and effectively reduce waste. According to a McKinsey and Company study, the utilization of Server operations in corporate information centers across the United States is "rarely more than 6%", and even up to 30% of Servers are in power supply but do not provide services. These so-called "coma cabinets" cause triple waste of room space, air conditioning and electricity.
Decommissioned or low-utilization equipment is hidden in telecommunications or information rooms. Although only basic operating capacity exists, it does not bring into play substantial benefits. Far EasTone Telecommunication, after discussion by the Environment and Energy Commission, formulates a "Decommissioned Cabinet Cleaning Plan", actively coordinates network engineering, IT telecommunications, facilities management departments, and aims at the entire switchboard room and self-use data. Cardiac checks were conducted to identify non-flow or low-flow, disconnected from network management, decommissioned or consolidated equipment in power transmission. A total of 210 cabinets and 114 sets of information room equipment were found to be consolidated and offline in the switchboard room. Afterwards, the executable quantity is evaluated and confirmed, and the power-off schedule of each equipment is arranged in batches. After confirmation, billing, measurement and statistics of power-off, the total reduction is 241 kW, 2.1 million kilowatt-hour power consumption is reduced throughout the year, and about 4.79 million yuan (NT) of energy cost is saved.
Far EasTone Telecommunication has joined in the energy-saving campaign in addition to base stations and computer rooms, and has planned incentives to save electricity and encourage colleagues to cooperate fully. The energy-saving action plan of the market includes: turning off the air-conditioner early when the temperature drops at night; turning on the corresponding number of computers at the counter according to the number of shifts; turning on only the first circuit lamps in the back office at ordinary times; closing the sign lights immediately after closing; turning off the computer at the end of work... And so on, accumulate great benefits from small actions.
In the introduction of energy-saving devices, Far EasTone Telecommunication in 2017 replaced old air conditioners and installed inductive lighting equipment in warehouses; Zhongdao display commodities in the market added circuit switches, one-button switching operation design, which can prolong the life of mobile phone batteries; in addition, 196 stores also canceled indirect lighting exhibition racks to reduce unnecessary waste.
In the fiercely competitive telecommunications industry, the effective promotion of energy efficiency is another battlefield, Far EasTone Telecommunication through different efforts, the third quarter of 2017 to the second quarter of 2018, the average energy-saving rate of 20%, is the best performance over the years. Excellent energy-saving performance not only won the "Far Eastern Group Energy Conservation Award 2018" - excellent institutions and non-manufacturing excellence. The project has won the Taipei Energy Conservation Leadership Award three times and set a new benchmark for energy saving and carbon reduction in non-manufacturing industries.
