Walking into the campus of the w88 casino in Chaoyang District, Beijing, one gets the impression that energy conservation and emission reduction can be seen everywhere“Shadow”: Solar street lights are installed on both sides of the road, the new library uses new energy-saving air conditioning technology, and the main teaching building has one floor“Thermal Clothing”, Bathing and hot water supply use new heating technology based on solar energy……

Hu Fuyin, the vice president of the w88 casino, told reporters:“Due to energy conservation and emission reduction measures, the w88 casino saves money in one year2500More than ten thousand yuan.”

Build a centralized reclaimed water station to collect rainwater and snow water, and frequently come up with new ways to save water

Colleges and universities are large energy consumers and have great potential to be tapped in energy conservation and emission reduction. In recent years, the w88 casino has made great efforts in this regard and achieved remarkable results. In the past, w88 casino sewage was discharged directly into the municipal pipe network. Ren Minghe, director of the Infrastructure Department, said,200410727_10771

“After demonstration at that time, the w88 casino established daily processing capacity1000cubic meters's centralized gray water treatment station, so that new buildings do not need to purchase gray water treatment equipment.”Ren Minghe recalled.

This reclaimed water is used in w88 casino office buildings, teaching buildings, student dormitories and other buildings70%Area flushing,30%Daily watering of green areas and water for landscapes such as square fountains and artificial lakes. Because the water contains nitrogen fertilizer, some campus green spaces are used as“Experimental field”After using gray water for watering, the grass becomes green.

Just when the first phase of the gray water treatment system achieved great success, Ren Minghe encountered another problem.“Unexpectedly, we later discovered that the gray water treatment capacity was not insufficient, but the sewage source was insufficient.”Ren Minghe said with a smile.

Originally, the daily treatment capacity of the reclaimed water treatment station was designed based on the early sewage discharge volume. Now, students' awareness of water conservation has increased significantly, and sewage discharge has naturally decreased.

What to do?Ren Minghe thought of a way to collect rainwater and snow water. He made a rough calculation, based on annual precipitation10times, each time5000cubic metersCalculation, the w88 casino can collect every year510,000 cubic metersof rain. So Ren Minghe began to plan to build a reservoir to collect rainwater and snow water.

In order to save land resources, most of the w88 casino’s rainwater collection pools make use of the terrain and landforms, and select abandoned heating ditches, air-raid shelters, self-prepared wells and other original facilities, and are directly connected to the reclaimed water station, with a rainwater collection capacity of up to 13720_13788|510,000 tons, nearly two years of water savings50Ten thousand yuan.

[Energy Saving Measures]：Implementing the third phase of reclaimed water project;Use of recycled water resources;Bathroom and water room useICCard;Comprehensive repair of pipelines, etc.

[Energy Saving Efficiency]：As the w88 casino’s building area, green area, and number of teachers and students continue to increase, water consumption has not increased, but decreased.2001The annual water consumption of the w88 casino is73.2Ten thousand tons,2007When the number of water users in the w88 casino more than doubled, the water consumption was57.2Ten thousand tons, a decrease of up to28.07%。

Install solar street lights, use low-voltage lighting, and use your brains to save energy

Walking around the campus, you can see that the street lights on both sides of the road are equipped with solar devices. It was getting late, and the street lights on both sides of the road did not light up at the same time. It turns out that these street lights are also equipped with intelligent sensor systems. In some dark areas with poor lighting, the street lights are lit in advance.

“Currently, the w88 casino is approaching420Replacement of street lights with solar street lights, the project has been completed80%, can save throughout the year after the project is completed4Thousands of kilowatt-hours of electricity, reducing carbon emissions38.14ton.”Ren Minghe said.

2009Year9In March, the w88 casino renovated the power distribution equipment and lowered the lighting voltage180Volt. Ren Minghe said that the measures to reduce the lighting voltage were tested on the third floor of the new library for a week in advance. The results showed that it could save electricity without affecting the lighting effect30%To35%。

[Energy Saving Measures]：80%’s campus street lights were transformed into solar street lights;Introduction of human body sensing lighting equipment in public areas;Apartments and teaching buildings realize one household and one meter;Replace lighting fixtures with energy-saving fixtures;Replace the oil-type transformer with an energy-saving dry-type transformer;Install energy-saving equipment in the power distribution room.

[Energy Saving Efficiency]：After the transformation of the power-saving project, the overall average power-saving rate reached20%;Among them, the replacement of energy-saving lamps brings economic benefits5010,000 yuan, reduce carbon emissions967The replacement of power-saving equipment in tons and power distribution rooms brings economic benefits16710,000 yuan, reduce carbon emissions3470ton.

Time-sharing zone heating, boiling water solar heating, careful budgeting on heating

As Beijing takes measures to control air pollution and bans coal burning within the Fourth Ring Road, w88 casino heating centers have also gone through a phase of switching from coal to gas. Since the price of gas is that of coal3times, heating costs have increased sharply.“Don’t underestimate the cost of heating in winter. You can burn a Santana a day.”Vice president Hu Fuyin gave reporters a simple calculation.

Gao Zhiwei, director of the w88 casino’s heating center, thought of using time-sharing and zoned heating, and quickly came up with a pipe network renovation plan. The w88 casino also quickly adopted this plan. The water balance control system of the heating pipe network was renovated. Through computer control, the heating demand time difference between the teaching office area and the dormitory living area was used to control the heating.

In this way, the heating center ensures normal heating of the teaching office building during the day and appropriately reduces the temperature of the student dormitories, and ensures normal heating of the student dormitories at night and appropriately lowers the temperature of the teaching office building. This approach has changed the traditional heating practice of uniform heating regardless of whether the weather is good or bad, whether there are people in teaching buildings or dormitories, and it effectively achieves energy conservation and emission reduction, and saves funds and expenditures in that year alone124Ten thousand yuan.

The w88 casino is using its brains in heating, and new ideas are emerging one after another, and solar water heating is one of them. The w88 casino water room uses solar energy to first heat the water to80Celsius, and then use electricity to heat it until it boils. If it is cloudy and rainy, electricity will be used to compensate to ensure the w88 casino's hot water supply. In this way, boiling a bucket of water from gas heating costs6900yuan, reduced to electric heating2700yuan, then down to solar heating251Yuan.

Since200722288_22332383.2tons, students’ bathing water, some domestic water, and canteen dishwashing water are all heated by solar energy.

[Energy Saving Measures]：Time-divided heating;Fume waste heat recovery;Solar hot water phase III;Water source heat pump project;Building outer layer insulation, etc.

[Energy Saving Efficiency]：Reduce the use of gas in the third phase of solar energy115To120cubic meters, annual savings22010,000 yuan;Integrity Building Energy Saving, Insulation and Energy Saving54%;Economic benefits of flue gas waste heat recovery7010,000 yuan;Economic benefits of water source heat pump7010,000 yuan, reduce carbon emissions228ton.

Up to now, the w88 casino has completed the comprehensive utilization of water resources, solar energy collection and utilization, groundwater thermal energy and geothermal energy utilization, and power-saving equipment and facilities, etc.17energy conservation and emission reduction projects, energy conservation work has formed a good cycle system.

[Short Comment]

Universities should set an example for resource conservation

Wang Ling, Secretary of the Party Committee of w88 casino:

Building a conservation-oriented and sustainable campus is an inevitable requirement for university development due to global environmental and resource issues. Universities shoulder unshirkable responsibilities and obligations in the country's implementation of sustainable development strategies.

Constructing a conservation-oriented campus is an important guarantee for the healthy and coordinated development of the economy and society, and is also an objective need for the scientific development of universities. In the context of energy shortages, the impact of the international financial crisis on the real economy, and very limited resources for running colleges and universities, colleges and universities should become an important force in promoting the construction of a resource-saving and environment-friendly society. Colleges and universities are not only large consumers of energy such as water resources and electricity, but also important bases for the research and development of energy-saving technologies. In building a resource-saving and environment-friendly society, they have great responsibilities and heavy tasks. They should use their advantages in disciplines, majors, and talents to use their brains, concentrate their wisdom, develop energy-saving technologies, and innovate management models.

Promoting the construction of a frugal campus is the need to cultivate high-quality talents with the traditional virtues of diligence and frugality who can shoulder the mission of building the motherland. College students are the future of the country and the backbone and main force of national construction. Their environmental protection awareness and sustainable development concepts will directly affect the effectiveness of our country's future sustainable development. As the cradle of cultivating talents, colleges and universities must not only impart knowledge and cultivate skills to students, but also must cultivate students' environmental protection concepts and enable students to develop the habit of saving.
