How does smart home achieve energy saving?

　　We already know that "building energy conservation" runs through all aspects related to buildings, such as building materials, construction and use. From a macro perspective, it is very important for the green environmental protection of the earth. From a micro perspective, it can also effectively control the energy bills such as electricity and gas bills at home. Overall, the energy consumption of buildings has accounted for 1/3 of the total energy consumption of society. We can know its importance by simply searching Baidu and Google. Then, returning to our lives, let us briefly talk about the actual manifestation of building energy conservation based on the selection of materials, construction and use of buildings:

　　1. Energy-saving building materials: This mainly refers to the energy-saving and environmental protection performance of the building envelope, which mainly includes:

　　①Exterior wall: The thermal insulation capacity of the enclosing structure will greatly affect the energy consumption of air conditioning or heating equipment in the building during future use. For the exterior wall, many people may think that reinforced concrete walls and ceilings are already very thermally insulated. In fact, this is not the case. There is a lot of knowledge involved. However, my country's real estate industry has not paid enough attention to this aspect during its explosive development, and Germany is worthy of learning from the whole world in this regard.

　　②Doors and windows: Door and window glass is a taboo for energy saving, but in order to live comfortably, we always want to have large floor-to-ceiling windows, or even skylights to see the stars. Otherwise, it is better to live in a basement that is warm in winter and cool in summer. Choosing energy-saving door and window glass can have a certain effect, but after all, many of them are heat-conducting and light-transmitting materials, which do not play a big role in energy saving. Therefore, the choice of shading materials and shading methods becomes particularly important. What we see more now is hanging curtains indoors. In fact, in theory, although it blocks the light, the energy-saving effect is not good, because the heat has entered the room through the glass. Therefore, in recent years, more and more external shading methods have been advocated, that is, preventing heat from entering the room as soon as possible outside the glass. Then some people say that this is too troublesome. It is troublesome enough to have a curtain inside, and you have to block the sun outside, and you can't figure out when to open and when to close it. Later we will discuss whether smart home can help.

　　③Roof, etc.

　　2、新能源的利用：最为典型的就是太阳能的运用，我们最为熟悉的就是太阳能热水器，这在我们很多地方都很受欢迎，太阳晒晒热水无忧，太阳能相对传统能源来说是绿色环保可再生的能源，不用白不用，今天用完，明天太阳照常升起，当然还有风能、地热等能源也在逐渐走进千家万户，在国外甚至这些新能源在自己用完还有多余的情况下，可以卖给电网，这岂不是一举两得甚至三得的好事情。我国在一些大型建筑上也尝试大面积采用太阳能电板，取得了一定的示范效果。

　　3. Intelligent building system: The intelligent building (BA, building automation) industry has gone through 20 to 30 years of history in China along with the reform and opening up. There are many practitioners. If you ask the people around you who are engaged in intelligent buildings what is the greatest contribution of intelligent buildings, they will definitely tell you that its greatest function is energy saving. Of course, intelligent buildings more often refer to large buildings, such as office buildings, large venues, hotels and other buildings. Effectively controlling the HVAC, lighting, shading and other subsystems of the entire building system will be able to save electricity to a great extent.

　　4. Energy-saving electrical equipment: As the government has recently promoted energy-saving projects to benefit the people, it is the first time that energy-saving products will be subsidized and promoted at the national level. This also makes us pay more attention to the "China Energy Consumption Label" and choose products with lower energy consumption.

　　At this point, it seems that we have talked a lot about energy consumption. In addition, energy waste may also be reflected in all aspects of our lives: forgetting to turn off the lights, forgetting to close the windows, forgetting to turn off the air conditioner, etc. How to prevent it? In addition to being educated to have energy-saving awareness, perhaps smart homes can help. Before discussing smart homes, let's take a look at the main aspects of energy saving in our lives from the perspective of home life.

　　Next, let's discuss the embodiment of energy saving from the perspective closest to our daily home life:

　　1. The first thing is of course the application of energy-saving products.

　　1) HVAC: This part of energy consumption accounts for nearly half of the entire building. New energy-saving technologies mainly include ground source heat pump air conditioning system, variable frequency air conditioning, etc.

2) Lighting: In recent years, the popularization and application of LED lighting technology 　　with higher luminous efficiency has greatly improved the energy waste of traditional lighting fixtures.

　　3) Standby power consumption of refrigerators and audio-visual equipment is the most easily overlooked invisible energy killer. The energy waste of standby power consumption is staggering.

　　2. Use new thermal insulation products such as outdoor sunshade.

　　As mentioned earlier, effective insulation can greatly reduce the workload of indoor air conditioning and heating equipment, thereby achieving energy conservation, especially for larger light-transmitting doors and windows.

　　3. Energy-saving awareness in home life is also very important.

　　1) Turn off high-energy-consuming equipment such as HVAC and lighting in a timely manner.

　　2) Close doors, windows and curtains in time.

　　3) Cut off the power supply of the equipment in time to prevent the loss of standby energy, etc.

　　Can smart homes save energy? That's right. A smart home system not only brings renewable technology into people's lives, but also brings energy conservation and environmental protection to society. The application of technology in smart homes has made many household products that originally consumed water and energy efficient and time-saving, and has played a role in energy conservation, either directly or indirectly. And how smart homes achieve energy conservation, I believe that friends who have read this article should have some understanding.
