The city's first public building energy conservation survey was completed a few days ago, involving commercial tastes of hotels, hospitals, schools, cultural sites, and main city road lighting. The results show that a large number of public buildings air-conditioning, lighting energy consumption is increasing year by year! The Municipal Construction Committee was informed that this year, the pilot project of energy-saving renovation will be launched, and relevant measures will be introduced to promote energy-saving renovation.
The “Research Report on the Energy Consumption Status of Existing Public Buildings in Chongqing†was completed by the Municipal People's Congress City Ring Committee, the Municipal Construction Committee Science and Education Department, the Municipal Building Energy Conservation Association and the Municipal Construction Technology Development Center.
323 public buildings surveyed
According to reports, public buildings in buildings are “large energy consumers†and are the focus of this census. 12 energy-saving experts from colleges and universities and research institutes formed an expert group on energy consumption survey, mainly involving the Municipal Tourism Administration, the Municipal Health Bureau, the Municipal Bureau of Land and Housing Management, the Municipal Cultural Bureau, the Municipal Commercial Committee, the Municipal Education Commission, and the Municipal The construction of 8 systems of the municipal and municipal municipal committees. It took nearly a year to find out the energy consumption “home†for the main large public buildings in our city.
The survey involved a total of 323 large public buildings with a total area of ​​5,565,100 square meters, mainly including heating, air conditioning, ventilation, water, lighting, cooking, various types of electrical appliances, elevators and other aspects of energy consumption. The city is famous for its “night viewâ€, so public lighting such as roads and landscapes in the city is another part of the survey.
95% of existing buildings are not energy efficient
It is understood that national building energy consumption accounts for about 27% of total social energy consumption, while 95% of existing buildings in our city are not energy efficient. With the comfort and health of the building, the building energy consumption is increasing year by year, especially in various public places. The energy consumption of air conditioning and artificial lighting in summer increases significantly.
“In the public buildings of this survey, the energy consumption is relatively serious, especially the hotel and business often.†The president of the Building Energy Conservation Association of the city, Professor Fu Xiangyu, the building energy conservation expert of the Ministry of Construction, introduced three reasons: one is air conditioning and lighting. The equipment itself is not energy-saving, and the way of using it is also very energy-intensive. For example, some hotels do not implement heating and cooling “layered controlâ€, and all air conditioners are turned on in the off-season; the comparison between shopping malls causes the light illumination to exceed the standard. Second, the awareness of management and staff's energy conservation is not too strong. Third, there are no incentives for energy-saving renovation and incentives in the city.
Hotel mall takes the lead in energy saving renovation
According to the survey, the total area of ​​public buildings in the main city of the city is about 26.93 million square meters, and the total energy consumption is about 920,000 tons of standard coal per year. Experts said that if these public buildings are energy-saving, they can save 440,000 tons of standard coal per year.
The 440,000 tons of standard coal saved after the transformation can account for 24.4% of the city's annual energy-saving index (1.8 million tons of standard coal). Among them, the market share of energy-saving after the renovation of the hotel, the store energy-saving can account for 8.9%, the hotel accounted for 7.5%, the hospital accounted for 2.6%, the district and county offices accounted for 2.8%, the other accounted for 1.3%.
The relevant person in charge of the Science and Education Department of the Municipal Construction Committee said that in order to decompose the energy saving and consumption reduction of 20% during the “Eleventh Five-Year Plan†period, the city will start the energy-saving renovation of existing buildings this year, and the hotel and business-taste institutions are expected to take the lead in implementing energy-saving renovation. .
Please give the building "energy-saving housekeeper"
According to reports, after the census, the experts proposed a proposal for the renovation of public buildings, and carried out a key analysis of the buildings of typical significance, providing a reference plan for building energy-saving renovation.
The expert group suggested that in the energy management of existing public buildings, energy consumption statistics and publicity and auditing systems should be established, and quota management should be implemented, such as low-value awards and excessive mark-ups.
The Ministry of Science and Education of the Municipal Construction Committee is responsible for the introduction. An important measure this year is to promote the “contract energy management†of existing buildings. The investment or financing of professional companies will carry out energy-saving renovation. The benefits of energy conservation are divided by the company and the owners, just like hiring buildings. An "energy-saving doctor" and "energy-saving housekeeper."

CAT7 Ethernet Cable known as Category 7 or Cat-7 cable is used to cable the infrastructure of Gigabit Ethernet. CAT7 Network Cable offers up to 600MHz. CAT7 patch cable supports high-speed ethernet communication up to 10 Gbps. These are backward compatible with Cat6, Cat5, and Cat5e categories.
You might be wondering whether it's worth your while to consider CAT 7 cable.
CAT 7 cable, whilst being the more expensive option, is also considered the most durable, and has a longer lifespan than CAT 5 and CAT 6, improving its overall return on investment, and is the best choice for wiring with the future in mind.
