Chengdu: Future construction energy consumption is not allowed

Water, Electricity, and Gas - These energy sources are necessary for everyone's daily life, as well as the energy consumption needed to maintain normal operation of every office building and public building. Today, environmental protection has increasingly attracted people's attention. Chengdu will also open more "prescriptions" for building energy conservation. In the future, the city will adopt energy audits, energy consumption quota management and other measures, so that building energy consumption is no longer "willfulness" - — This reporter learned from the Chengdu Municipal People’s Working Conference on Energy Consumption and Energy Saving Information Statistics at a meeting yesterday.

Understand: The potential for energy savings in office buildings and public buildings is huge

“In today’s increasingly environmentally regarded environment, the management and control of building energy consumption has also been mentioned on the agenda. Before implementing dynamic management, we must first understand how much water and electricity will be consumed in single-building buildings during the year.” The relevant person in charge of the construction committee said yesterday at the statistics and statistics meeting of the energy consumption and energy saving information for citizens in Chengdu.

The reporter learned from the meeting that the building energy consumption survey conducted in the city last year retrieved the energy consumption information sheet for 4,130 buildings, including 630 government offices and public buildings and 3,500 residential buildings. The "2014 Chengdu Civil Building Energy Consumption Survey Report" announced at the meeting showed that the power consumption per unit area of ​​office buildings and large public buildings in the national institutions of Chengdu is significantly higher than that of residential buildings, and there is a huge potential for energy saving. It should be used as Chengdu City. Building energy-saving focus.

The investigation report put forward corresponding measures and recommendations from the three aspects of energy-saving operation optimization management, energy-saving technological transformation, and energy-saving system. After the estimation, through these changes, Chengdu can save 380 million kilowatt-hours of electricity per year, which can save about 380 million yuan. Yuan ***; total emission reductions have been estimated at 90,000 tons/year.

Weapons: This month's use of "free air conditioning" is the most affordable

“The significance of the energy consumption survey is to provide a basis for building energy conservation.” Yesterday, the report writing team member, Associate Professor of Xihua University told Yong to reporters that there are actually many tricks for building energy consumption, such as reasonable choices. Operating time, pre-cooling time should not be too long, open 0.5 to 1 hour before cooling, 0.5 to 1 hour before the end of cooling; recommend that when the outdoor temperature is higher than 35 °C, the indoor environment temperature is controlled at 26 °C or more, because It is estimated that for every 1°C increase in indoor ambient temperature, the cooling load can be reduced by 10% and the operating cost can be reduced by about 8%.

In March of Spring in Yangchun, there is a ready-made energy-saving coup: “In the transitional period, from November to March, most commercial office buildings need cooling because of internal heat sources such as people, computers, and lighting. When you can use the fresh air system, introduce colder outdoor air to meet the needs of all or part of the cooling, thereby reducing the energy required for system cooling, which is 'free air conditioning'." Said Yong.

Future: Excessive energy audit energy costs will be high

What will be the dynamic actions after the static investigation? The relevant person in charge of the municipal construction committee stated that the Ministry of Housing and Urban-Rural Development recently issued the "Implementation Opinions on Strengthening the Management of State Offices Office Buildings and Large-scale Public Buildings for Energy Conservation", which included Chengdu as a pilot city for dynamic monitoring, statistics, and auditing of energy consumption.

The basic data provided by the survey on building energy consumption will be used to establish energy management mechanisms for the operation of large-scale public buildings, carry out various energy-saving and emission reduction tasks, and mobilize enterprises and social forces to carry out energy conservation and emission reductions. “In the future, building energy will inevitably no longer be 'precarious', and we are expected to carry out statistics and publicity of energy consumption in accordance with relevant regulations. How much energy a building consumes must be sun-burned, and the establishment of a “building energy audit” system is also a future. With regard to development trends, the auditing unit will supervise and inspect the physical and financial processes of building energy use in accordance with relevant national energy conservation laws, regulations, technical standards, and consumption quotas, etc. If the energy consumption quota management system is implemented in the future, The excess will be charged at a higher price," said the person in charge.
