At the turn of summer and autumn, the sun is like fire, and major shopping malls have become one of the first choices for citizens to spend their summer vacation. The major shopping malls in Shushan District of Hefei City have done their homework for this, which will not affect the shopping experience of customers, but also achieve the goal of energy saving and emission reduction, and energy saving can be seen and felt.
    A special nano-metal film was pasted on the top of the shopping mall.
    Put on the new material of "sun protection clothing" on the roof to effectively insulate heat.
Entering Hefei Vientiane City, the dome glass on the roof is beautiful and beautiful, becoming a landscape. "The dome glass is more transparent and can reduce the energy consumption of lighting, but in summer, when the sun is direct, the temperature is higher." Introduction of Zhou Century, the foreman of Vientiane City Engineering Department. Now, a special nano-metal film not only effectively reduces the light transmission, but also reduces the surface temperature by more than 10 degrees Celsius.
    At present, the dome of Vientiane City Mall covers nearly 2000 square meters of coating. "The dome film significantly reduces the energy consumption of air conditioning in summer by effectively isolating heat, and also achieves the environmental protection goal of energy saving and emission reduction." Zhou Century said that it is expected to save more than 400,000 kWh compared with last year.
    In addition, Wanxianghui in Shushan also stuck a heat insulation film in the glass lighting area of the atrium, and the downlights and light belts in the infield were completely transformed and replaced to reduce energy consumption. Compared with previous years, it is expected to save 200,000 kWh, effectively reducing energy consumption.
    "Festival" tries its best to make the shopping mall "green"
    Central air conditioning is also a high energy consumption facility in shopping malls. Hefei Vientiane City installed a frequency converter to reduce the energy consumption of air conditioning, set the air conditioning temperature to a fixed value, automatically adjust the fan frequency and reduce the fan output power.
    In the underground garage of Vientiane City, each lamp can save energy by 50% by installing the LED radar induction lamp. According to Zhou Century, for emergency lights that need constant lighting, since January this year, the original 18-watt lamps have been replaced with 5-watt high-efficiency lamps, which can reduce power consumption by more than half under the premise of constant illumination.  
    Hefei Vientiane City.
    Vientiane City in Hefei and Wanxianghui in Shushan were awarded as "green shopping malls" by the Ministry of Commerce in 2022. On August 7, we saw on the energy efficiency management platform of Hefei Vientiane City that the temperature and carbon dioxide content of each floor were clearly visible. Zhou Century said that shopping malls will update and upgrade facilities and equipment according to the requirements of energy saving and consumption reduction.
    Energy-saving and Carbon-reduction of Peak Electricity Consumption
    "Our air conditioning temperature is set at 27 degrees Celsius, but in fact, the electricity consumption is only 30% of that of ordinary air conditioning systems, which is all derived from the comprehensive energy management plan." The person in charge of Hefei Hongyang Square said.
    At present, Hongyang Plaza adopts the mode of cold storage at night in the air conditioning system, which uses the underground cold storage pool of about 4,700 cubic meters to store cold in the electricity bill valley for 9 hours from 12: 00 pm to 9: 00 am the next day. The "cold air" stored at night can be emitted only by driving with a small amount of electric energy during the business hours of the shopping mall during the day.  
The staff of the shopping mall put sealing strips on some doors to reduce the outflow of cold air.
    "We have also launched a centralized publicity campaign for energy conservation and emission reduction, and popularized the concept of green development and knowledge related to energy conservation and emission reduction to the public by distributing publicity materials and placing exhibition boards." The relevant person in charge of the Shushan District Bureau of Commerce said.
    In addition, the Bureau of Commerce of this district also urged the large commercial complexes within its jurisdiction to save energy and reduce consumption by transforming air conditioners, elevators, lighting systems and other equipment, and installing heat insulation and sun protection devices, so as to provide green kinetic energy for the high-quality development of the business circle.
