[abstract] energy conservation and emission reduction is the country's economic and social development of a long-term strategic policy, but also the present a very pressing task. Higher school with teaching, researching and life at an organic whole, with the constant expansion of school, the campus area, students, faculty, staff number sharp increase, the energy consumption of the surge in school fees, cause students develop cost increase, the school funds, directly influence the school will be limited funds in teaching, scientific research, and other key aspects. This article puts forward the general idea of energy conservation and emissions reduction and the countermeasures, constructing economical colleges, universities should consider is the problem.
[key words] university, infrastructure and save energy
A. The present situation of energy conservation and emission reduction in universities in China
College infrastructure construction need resources are divided into two aspects: electric power resource and water resources.
1, electric power resource utilization. Most of the university electricity by social power supply departments supply, a few schools have a power plant, according to the scale computing electricity charges. Colleges and universities in the electric power resource utilization in the main problems are: (1) the classroom, office, students' dormitory ever-burning lamps phenomenon exists generally, the day, sunny day or indoor no lights long out; (2) public lighting equipment high power, distribution is not reasonable, (3) the main power consumption equipment can not reach the standard of energy saving;
2, the present situation of water resources utilization. Colleges and universities in the water and energy saving the problems existing in the mainly include: (1) the students water saving consciousness difference. (2) did not execute students water caused by quantitative water waste. (3) sanitary ware and flushing equipment not water saving. (4) the water supply management system is not sound. (5) two water supplies large energy consumption.
2. College foundation construction energy conservation and emission reduction problem analysis
1, new energy, means to lack. Capital investment in the construction of campus, but the green environmental protection of solar energy, such as heat source to new energy, new technology has not been fully utilized. According to estimation, radiation on earth every year to solar energy for 1.78 billion kw, which can be developed using 500-100 billion degrees. A school classroom if press 100 is between, each classroom 6 lamp, every light 10 W, if use solar year can save 23652 yuan.
2, daily management level is low. University building complex functions, implementation of the building energy department many, mostly college daily energy management professionals lack. Hard to establish effective daily management system. Plus students fluidity big, is not focused, and a classroom sometimes only a students' self-study, but put all the lights are open, cause great waste.
3, energy saving incentive system construction not perfect. Part of the school in energy management regulations are perfect. But most of the lack of efficient energy management incentive system. In the use of the university in the process of policy support and lack of funds subsidies incentive system, the development of the college certain limits, cannot construction and energy saving supporting facilities, resulting in waste of resources.
4, building energy saving rate is low. The so-called building energy efficiency, first is to point to reduce the loss of energy in the building, and is now commonly known as improving energy efficiency in buildings. In order to ensure that improve the building under the premise of comfort, reasonable use energy, and constantly improving energy efficiency. Our country in building energy saving the development on the whole is relatively backward, most universities building use over a long period of time, building energy saving rate is low; Most of campus building also by school funds influence, in building energy saving commitment was limited.
3. University of energy saving and emission reduction method
1, raise lighting equipment efficiency
Configuration lighting lamps and lanterns, schools should consider different occasions lighting should choose high efficiency with different performance of the bulb. For example: roads, in addition to the other of indoor and outdoor sports outside T5 lights and LED instead of T8, high-pressure sodium lamp. The stadium, lighting stadium with high efficiency of fluorescent lamp and LED lights instead of low efficiency of incandescent lamp.
The characteristics of various light contrast
Light lamp power types
(W) light throughput
(LM) power factor average show color
Index (Ba) color temperature
(K) average life expectancy (h)
Indoor T5-2900 > > 0.95 energy-saving 28 80 4100 > 10000
T8-inductive fluorescent lamp 36 2500 about 0.5 < 65 4500 5000
Outdoor LED 150 w 18000 > 0.97 80 6000 50000
High pressure sodium 150 w 15000 about 0.4 70 ~ 80 2000 12000
2, improve the power system efficiency.
Power grid in the loss is a kind of objective existence of the physical phenomenon, can reduce and inevitable. Using the new energy-saving technique to college classroom lighting electricity saving transformation, realize the classroom light terminal intelligent automatic control management, can effectively eliminate the classroom illume to waste phenomenon, the enormous social benefits and economic benefits.
3, implementation plan to use water, water meter metrology management.
Water is the premise of implementation plans to install water meter, for norm metrology management. In the choice of measurement meter, according to the existing buildings water characteristics and water supply network layout of the reasonable selection. At present, our country meter reading technology can be divided into: (1) the power carrier automatic meter reading system. (2) the smart card water meter. (3) points ChuanChao line in the far way table. (4) the bus system intelligent meter reading way. (5) wireless transmitting type vane wheel water meter. Through the investigation, reading about material, grasps the above five kinds of water meter of technical and economic characteristics, from economics and management of water meter of the choice adds up to all realize quantitative management with water. The management of the main measures are: (1) water management system reform, improve the system construction. (2) the extensive publicity, make the teachers and students staff to establish consciousness of water saving consciousness. (3) underground water supply pipe out, draw water supply pipe system diagram. (4) increase the funds investment, improve water supply infrastructure. (5) the backward water appliances, thoroughly water saving appliances transformation. 6 perfect measurement network system, regularly carry out water balance test work. 7 brother institutions absorb good practices, and school logistics management department together, formulate measures for the management of water saving. As to the student dormitory water, a quota management, with the charge system, water price system of tuition fees and implementation steps.
4. College for energy conservation and emissions reduction significance
University of energy saving and emission reduction is whole society an organic part of the energy conservation and emissions reduction, in university extensively in energy conservation and emission reductions, from on macroscopic to speak, not only for the whole society for energy conservation and emission reduction in a leading role radiation, even more important, can be directly education students to build up the energy conservation and emission reduction in consciousness, make a treasure of resources, environmental protection consciousness of the behavior. Microscopically speaking, can save the cost of running a school, the limited funds more into the teaching and scientific research. At the same time university on college students' of energy saving and emission reduction has an important education demonstrative effect. Five. Last word
Save energy, the GongZaiDangDai in later generations, and is an effective way to save the university spending, also is the inevitable requirement of building the saving-type campus. We must to a scientific approach to energy conservation of the global, with practical work style and attitude, further implement the central party committee about "energy development and save, save and priority" the policy, the proponents of wind energy saving, energy saving as beneficiary. On the energy saving in the face of present situation, increase energy conservation and propaganda work dynamics, the energy conservation consciousness, and establish and perfect rules as soon as possible energy saving system, strengthen the team building energy conservation, promote, and the use of energy saving new technology, to improve the energy saving effect, and for the sustainable development of the country and school make more contribution.
