Universities are also low-carbon
（《Southern Weekend》2010Year4Month 29日C14Edition reporter Pan Xiaoling intern Ding Jie)
■If nearly a thousand universities across the country become“Low Carbon University”, you can save about in one year210100 million yuan. In addition, you can save26The water volume of Wuhan East Lake will increase the green area by seven and a half times the size of Hong Kong.
■How much impact will students who believe in low-carbon concepts have on traditional social concepts? Vice President Hu Fuyin’s answer is,“Immeasurable”。
“Low carbon”It is no longer a lively word in writing or slogans. The w88 casino is starting from the simplest“Saving energy equals saving money”8575_8612“Low Carbon University”. More importantly, their actions affect every student living in this university who will become the backbone of society and reshape social values
Even the underground cannot be idle. Every morning, before the library welcomes its first reader, buried on the surface100The groundwater under meters has started. It is related to the surface temperature20A difference of about Celsius, enough to supply this building the size of three football fields year-round18Celsius constant temperature.
Other unwelcome wastewater, when it rains, after the faucet is unscrewed, it passes through several sewage pipes and ten reservoirs, gathers it together, is filtered, aerated, and sedimented, and is then transported out through several blood-vessel-like dense pipes to be used for flushing toilets, watering flowers, and raising small goldfish in the constant-temperature library.
When night falls, the solar panels placed on the roofs of buildings and street lights begin to release energy after absorbing sunlight for a day——The light of the street lamp, the hot water in the bathhouse, and the boiling water in the water room……
If you don’t pay attention to the large number of solar panels of different sizes and the small earth bags used to bury reservoirs and wells scattered everywhere, the w88 casino is no different from other university campuses.
In the military training reports of previous freshmen, the w88 casino’s senior leaders always mentioned it repeatedly,“We want to be the Switzerland of Beijing universities.”（“Switzerland”Famous in Europe for environmental protection and energy saving. )
This one“Switzerland”12938_129462004Year, the first block was built“Brick”'s motivation is to save money.
At that time, the w88 casino launched three projects: stadium stands, teaching buildings and student apartments at the same time. According to the Beijing Municipal Construction Committee1990Regulations implemented at the end of the 1990s require that every new building must be equipped with a gray water treatment system. Gray water is between sewage and tap water and is used for flushing toilets, watering plants, washing cars, construction sites, and dust suppression.
The w88 casino proposed after argumentation to build a daily processing capacity of1000tons of gray water treatment station, centralized treatment of wastewater from several buildings. It is possible to build a website, but the equipment can only be used in Europe decades ago“Physics+Biochemistry”Technology, this technology cannot treat toilet sewage, the reason is obvious: save money.
The effect of this equipment, which cost more than one million yuan, exceeded many people’s expectations,“We saved more than 2 million yuan in water bills that year.”Ren Minghe, Director of the w88 casino Infrastructure Department said,“After you taste the sweetness, you can’t stop.”
200515607_15673“Have to burn a Santana every day.”
“Stingy”The way will be found soon. At that time, many domestic hotels had begun to use heating control systems. This system was not very technical and was equivalent to an alarm clock. After setting the time and location, the heating gate would supply the set heat according to the instructions.
The whole system is spent163Ten thousand yuan, the cost was recovered that year. According to the comparison of energy-saving data provided by Ren Minghe, after heating timing and fixed-point regulation, the daily heating bill was saved by half.
In the view of Vice President Hu Fuyin, the greater gain is the impact of ideas——Environmental protection and development are by no means either/or enemies. We must sacrifice each other to preserve ourselves.
200718152_18195“Serious”, the w88 casino has almost nothing to throw away——
Toilet wastewater can also be treated in the third phase of the gray water treatment station. The technological content of this new equipment has been synchronized with Europe;
The exterior wall of the teaching building is“wear”Previous extruded board“Coat”He broken bridge aluminum alloy insulated glass thermal insulation window“Small coat”After 19498_19537|, the air conditioner and heater can only be used indoors for a long time, so that teachers applied to the w88 casino for distribution of shirts in the winter“Subsidy”；
The chimney of the canteen was not spared, it is as high as280The residual temperature of multiple degrees Celsius is now being protected by a large iron cage with several water pipes“Exploitation”, this iron cage is equivalent to a giant water heater. The water passing through the water pipe can be heated to30～40Celsius;
Even the soil stepped on every day has become a usable energy source. On a construction site not far from the constant-temperature library, a scientific research building will be completed next year. The constant-temperature system is still used indoors, and the ground provides support100Soil under meters, its principles and support“Neighbor”The library's groundwater is the same.
The water after bathing in the bathhouse was also used by Ren Minghe“Stare”Up. In his opinion, these temperatures reached30～40It is a pity that the remaining water at degrees Celsius is directly transported to the reclaimed water treatment station as waste water.
Of course, there is also the idea of letting it go. Because the cost of putting it into practice is too high and the input-output ratio is not cost-effective, the solar energy collected at present can only supply street lights and heat cold water, and supporting the indoor electricity consumption of the entire building can only be theoretical for the time being.“But this technology has already been put into use in many cities in the West.”Ren Minghe said.
The idea of using water source heat pumps to support the constant temperature system of the library was inspired by a graduate at a party. The young man working in Canada said that if any company or institution adopts energy-saving technologies such as water source heat pumps and ground source heat pumps, it can receive government subsidies.
For Ren Minghe, who studied architectural structure, these two terms are,“This is actually the first time I heard it”. This item“Frontier”'s use of technology helped the library win the Luban Award, China's highest architecture award, last year.
After rough calculation, the energy-saving systems placed in every corner of the campus can provide the w88 casino with enough energy in one year“dig”Appointment2100Ten thousand yuan, if nearly a thousand universities across the country become“Low Carbon University”, you can save about in one year210Billion yuan. In addition, you can save26The water volume of Wuhan East Lake increases the green area by seven and a half times the size of Hong Kong.
However, the foreign economic and w88 plan was almost disrupted. Since ground source heat pumps with similar principles require large areas of open space to inject heat,2007When building a new library in 2008, Ren Minghe decided to use a water source heat pump considering the lack of surrounding open space. Shortly thereafter, the relevant authorities banned the use of water source heat pumps due to insufficient groundwater in Beijing.
Ren Minghe sighed,“Low Carbon University”This idea is most suitable for new campuses and new communities. When designing buildings, the underground water source and ground source heat pump should be buried, as well as the location of the gray water treatment station on the ground and the space for solar panels in the sky.“It's like decorating a house. You have to complete the hidden wiring first and then carry out the overall decoration.”“This idea of incorporating environmental protection and emission reduction into planning has been used in the West for many years.”
In any case, this site located on the Third Ring Road in Beijing500Multiple acres“Low Carbon University”, is playing a subtle role in demonstrating. Ma Lan, a junior at the w88 casino, has now realized his“Ningba”, I went out on the streets with my classmates from other schools several times and picked up flyers when I saw them on the ground. I never use them when I go to bookstores and supermarkets, and I don’t allow others to use plastic bags.
Ma Lan is suffering from similar illnesses“Obsessive-compulsive syndrome”27026_27048“Hidden rules”, at the end of each semester, we collect the unused textbooks from our classmates and distribute them to junior students at the beginning of the next w88 casino year. Everyone is also used to accumulating newspapers, periodicals and waste paper that they usually read, and asking colleagues from the w88 casino green association Learn to exchange recycled paper notes.
There is no doubt that the Malans will become the backbone of society in the future. How much impact will they have on the people around them and on the traditional ideas of society? Vice President Hu Fuyin’s answer is,“Immeasurable”。
