How to reduce the carbon footprint of buildings? Measures to reduce carbon emissions

At present, the primary task of reducing the carbon emissions of buildings is to reduce the energy consumption during use, and many countries around the world have issued corresponding regulations, policies and technical standards to reduce the energy consumption in the operation of buildings. For different types of buildings in different regions and under different climatic conditions, there are certain technical regulations and standards for their energy consumption. Among them, residential buildings are the largest number of building types in the city, and there are corresponding standards and regulations for related energy consumption.

Therefore, in order to reduce the carbon emissions in the process of use, through reasonable planning and design, it is first necessary to meet the relevant building energy conservation standards, strict construction and scientific use management, and reduce the energy consumption during the use of the building, so as to achieve the purpose of reducing the carbon emissions of the building.

In order to reduce the carbon emissions of the building use part, it is necessary to distinguish different energy types (oil, coal, electricity, natural gas, renewable energy, etc.) according to the energy consumption of the building in the process of use, calculate its one-time energy consumption, and then convert the corresponding carbon dioxide emissions. In this production process, it is necessary to pay attention to the tracking of the energy use part, emphasizing the saving of one-time energy consumption in the use process, including increasing the proportion of renewable energy in the heating and power supply parts, rather than blindly pursuing the promotion of photovoltaic power generation and wind power generation in urban buildings, because the application of these technologies is subject to many restrictions, and the final energy saving and emission reduction effect is limited.

At the same time, reducing carbon emissions, energy conservation and consumption reduction need to work together from top to bottom, from the industrial structure and developers, to the design and builders, from the production and construction of buildings to reduce carbon emissions, and as consumer buyers, the purchase of low-energy, low-carbon buildings is also to make a contribution to reducing carbon emissions.

Advocating diligence and thrift, avoiding extravagance and waste, and putting an end to large and inappropriate buildings are important components of reducing carbon emissions in buildings.

In addition, green travel has also been often mentioned in recent years. Therefore, in the pre-construction planning, it should be advocated to take public transportation and rail transit as the leading factor as much as possible, set up public transportation stations about 500 meters, build commercial service facilities that meet the purchase of daily necessities and daily life, so as to reduce the amount of travel, establish and redevelop a humanized bicycle road system and storage system, meet the needs of modern life development, and reduce the carbon emissions of overall travel to a lower level. These are closely related to the planning and design of our residential buildings, but strictly speaking, they belong to the category of reducing carbon emissions in the transportation system, belong to the interdisciplinary field, and are important indicators for low-carbon cities.

According to Cao Bin, deputy secretary of the Party Committee and general manager of the China Building Standard Design and Research Institute, China's construction industry can adopt the method of "opening up sources and reducing expenditures". At the beginning of construction, the amount of high-carbon building materials should be reduced, such as the use of prefabricated interiors, and the replacement of cement and sand cushions with overhead layers, which will reduce emissions and facilitate replacement and material reuse. There is also the use of renewable energy, the Ministry of Housing and Urban-Rural Development in the "13th Five-Year Plan for Building Energy Conservation and Green Building Development", clearly requires to further promote the use of renewable energy

It is necessary to build solar photovoltaic facilities on the roofs of buildings and the facades of buildings in suitable conditions. By 2022, more than 10GW of new installed capacity of solar photovoltaic building applications will be added in cities and towns across the country. ”

It is understood that there are mature cases of using solar energy to achieve all energy supply in buildings in China - the "0+ Hut" project in Huifengxi Smart Energy Town of Sino-Singapore Tianjin Eco-City, with the help of 60 photovoltaic panels with a total of 20 kilowatts, has successfully realized the clean energy supply of the whole house, including heating. However, the application and development of China's building photovoltaic field is still in its infancy. However, the development of building photovoltaics is growing rapidly, and the forms are becoming more and more diverse, showing great potential.

Measures to reduce carbon emissions include:

1. Actively respond to alternative technologies such as clean energy substitution technology, renewable energy substitution technology and new energy technology;

2. Improve energy efficiency and reduce CO2 emissions by reducing energy consumption;

3. The use of fiscal and financial policies such as taxation can optimize the allocation of resources, accelerate the process of technological transformation, and reduce the cost of emission reduction in the whole society;

4. The use of terrestrial ecosystems such as afforestation, forest land restoration, high-yield forest management, logging management, forest fire prevention and pest control to increase the carbon absorption of terrestrial ecosystems can reduce carbon emissions and increase forest carbon sinks;

5. Reduce carbon emissions from human consumption.

Ways to reduce carbon emissions in daily life include:

1. Use natural light, save power and delay the cycle, choose to work in a place with sufficient natural light, do not turn on the lights when the natural light is sufficient, use energy-saving bulbs to illuminate, and develop the habit of turning off the lights when ensuring brightness;

2. Scientific use of computers, good power-saving effect, adjust the computer screen to medium brightness, which can not only save power but also protect eyesight;

3. Double-sided paper, mail for letters, and paperless office is advocated;

4. Green and low-carbon travel, public transportation helps reduce traffic congestion and carbon emissions;

5. Low-carbon diet, reduce food waste, and actively practice civilized meal distribution and "disc action".

Legal basisArticle 6 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution.

Local people at or above the county level shall encourage and support research on atmospheric environmental protection science and technology, the causes of air pollution and prevention and control countermeasures, promote advanced and applicable air pollution prevention and control technologies and equipment, promote the transformation of scientific and technological achievements, and carry out relevant scientific and technological exchanges and cooperation.

Article 50. The state advocates low-carbon and environmentally friendly travel, reasonably controls the number of fuel-powered motor vehicles in accordance with urban planning, vigorously develops urban public transportation, and increases the proportion of public transportation trips.

The state shall take fiscal, tax, procurement and other measures to promote the application of energy-saving and environmentally friendly and new energy motor vehicles and ships, non-road mobile machinery, restrict the development of high fuel consumption, high emission motor vehicles and ships, and non-road mobile machinery, and reduce the consumption of fossil energy.

The people of provinces, autonomous regions and municipalities directly under the Central Government may, in areas where conditions are met, implement the emission limits of the corresponding stage in the national motor vehicle air pollutant emission standards in advance, and report to the competent department of ecology and environment for the record.

Urban people should strengthen and improve urban traffic management, optimize road settings, and ensure the continuity and smoothness of sidewalks and non-motorized lanes.

1. People can reduce carbon emissions by driving fewer private cars, insisting on climbing buildings, and choosing to turn off computers when they are not in use.

2. In life, on the one hand, we should encourage the adoption of a low-carbon lifestyle and reduce carbon emissions; On the other hand, a certain amount of carbon offsetting measures is used to achieve balance. Planting trees is a way to be "carbon neutral", and the number of trees (trees) that need to be planted is equal to the amount of carbon dioxide emitted in kilograms divided by it.

3. Clothing, change with the season, wearing appropriate seasonal clothing can reduce the use of air conditioning. Choose eco-friendly fabrics and reduce washing, opt for hand washing, and reduce the purchase of clothing.

4. Food, buying local, seasonal food, and reducing food processing can reduce carbon dioxide emissions. Using a cooking method with less oil, less salt and less processing, you can be healthy not only for yourself, but also for the planet.

5. Living, the living area does not have to be large, and the rational choice is suitable for the house type. This is because the reduction in the size of the dwelling can reduce the use of water and electricity, which invisibly reduces CO2 emissions.

6. Okay, choose the right car type and take more public transportation. Cars are a major emitter of carbon dioxide, so you should try to choose a car with low fuel consumption and more environmental protection.

7. Use, recycle vegetable washing water and bath water, only install energy-saving lamps in each room, do not eat chewing gum, use fashionable environmental protection bags, double-sided printing, do not use disposable tableware, and try to buy products with simple packaging, which not only reduces the energy consumed in production, but also reduces garbage.

8. When using the washing machine, with the same long washing cycle, the "softening" mode has more times of impeller reversal than the "standard" mode, and the starting current of the motor is 5 to 7 times of the rated current, and the "standard washing" is more energy-saving;

9. If every car driver pays attention to inflating tires in time and appropriately, the energy efficiency of the vehicle can be increased by 6%, and each vehicle can reduce 90 kg of carbon dioxide emissions per year;

10. When processing food in a microwave oven, it is best to add a layer of non-toxic plastic film or cover the food with a lid, so that the moisture of the processed food is not easy to evaporate, and the food tastes good and saves electricity.

11. According to expert statistics: for every 1 kilowatt-hour (kWh) of electricity saved, kilograms of standard coal are saved correspondingly, and at the same time, pollution emissions of kilograms of carbon dust, kilograms of carbon dioxide, kilograms of sulfur dioxide, and kilograms of nitrogen oxides are reduced.

There are many ways to reduce carbon emissions in life, such as replacing standard incandescent bulbs with energy-saving bulbs, which save more than 2 3 energy compared to incandescent bulbs; Choose a greener way to get around, whether it's by bus or carpooling; Shortening the bath time not only saves water, but also saves energy when heating the bath water; Buy local food, choose local products, eliminate the need for air freight, and be greener.

Low-carbon life means that we should try our best to reduce the energy consumed, especially the emission of carbon dioxide, so as to be low-carbon, reduce pollution to the atmosphere, and slow down ecological deterioration. Low-carbon living can be understood as: reducing carbon dioxide emissions, low energy, low consumption, low expenditure lifestyle.

It is mainly from the three links of power saving, gas saving and ** to change the details of life. Low-carbon living is not only a way of life, but also a sustainable environmental responsibility.

1. Ride more bikes and sit more.

refining the body, it can also save energy and reduce 2, buy simple packaged goods, green food, and advocate green consumption; Bring your own shopping bag when you go shopping. 3. Do not waste homework and homework paper, use draft paper reasonably, printing paper can be used on both sides, save consumables 4, save electricity, turn off indoor lights, fans, computers and more, save every kilowatt-hour of electricity 5, do not litter, and classify garbage.

** Utilization of garbage.

On weekdays, we can use energy-saving light bulbs, turn off the lights at will, plant a variety of plants at home, drive less private cars, insist on climbing buildings, choose to turn off the computer when not in use, etc., to minimize carbon emissions in our daily life, low-carbon life includes: low-carbon electricity, low-carbon travel, low-carbon diet, etc.

Minimize the use of white plastic and disposable items on weekdays, and use cloth bags or biodegradable plastic bags when shopping. Try to drive as little as possible, because car exhaust is a harmful substance, which can reduce the harm to the environment caused by car exhaust emissions. Do a good job of garbage classification, do not litter, garbage classification can promote the effective recycling of resources, reduce environmental pollution.

And to make the house more sealed. Another great way to save energy is to keep as little air leaking out as possible. Make sure the walls of your home are insulated.

You can also consider switching to double windows, which are more expensive, but you'll save more energy in the long run when heating and cooling. You should also add seals around doors and windows. This will close the gaps and make your home's heating or cooling system more energy-efficient.

1 4 Adopt alternative technologies for fossil energy to actively respond, mainly including clean energy alternative technologies, renewable energy technologies, and new energy technologies.

2 4 Reducing CO2 emissions by reducing energy consumption by improving energy efficiency. The adoption of cleaner production technologies to improve energy efficiency, especially the clean use of coal, will play a very important role in the next 15 years. Energy efficiency technologies not only reduce energy use, reduce emissions, and improve cost-effectiveness, but also realize greater potential through technology transfer.

3 4 In agriculture, improve the utilization rate of chemical fertilizers. On the premise of ensuring crop yield, reducing fertilizer consumption plays an important role in reducing CO2 emissions and protecting the environment in the process of chemical fertilizer generation.

4 4 The use of fiscal and financial policies such as taxation can play a role in accelerating the process of technological transformation, optimizing the allocation of resources, and reducing the cost of emission reduction for the whole society.

Energy conservation and environmental protection are the social responsibilities of each of us, so what can we do to reduce carbon emissions?

1. Ride more bicycles and take more buses, which can not only exercise, but also save energy and reduce emissions.

2. Buy simple packaged goods, green food, and advocate green consumption; Bring your own shopping bag when you go shopping.

3. Do not waste homework books and homework papers, use draft paper reasonably, and printing paper can be used on both sides to save consumables.

4. Save electricity, turn off indoor lights, fans, computers and more to save every kilowatt-hour of electricity.

5. Do not litter, and classify garbage, and collect the most usable garbage.

6. Use less disposable products (wooden chopsticks, paper cups, paper towels, lunch boxes, etc.), and do not waste every grain of food.

Let's strive to "do more and do more" to reduce carbon emissions. Together, we will protect our common home.

Generally, when we use a car, we will remove car exhaust, which contains carbon dioxide and other substances, which will affect the greenhouse effect and pollute the air. Therefore, we can try to use public transport, bicycle or walking.

Pay attention to saving, save electricity, develop a good habit of turning off the lights and other electrical equipment, and do not waste one kilowatt-hour of electricity.
