In all the industries in China, the construction industry is one of the most important industries, but it is also a threat to the industry. The reason why the construction industry is one of the most important industries is because it has a very important role in the current economic growth, the construction industry, the threat of performance in its high energy consumption. In today's society, people increasingly high demand for life, but living environment but in the continuous deterioration, in the face of under the trend of global warming climate change more and more extreme, making people more and more want to build the building energy saving and environmental protection. Decoration construction as part of the construction project, so the green environmental protection in the construction of which is also very important.
1 the concept of green decoration construction
In today's society, we are more and more pursuit of the concept of environmental protection decoration. Decoration of the raw materials in the production and processing and construction to maintain its function after the completion of the resources must be spent, and the use of the construction process in the waste of the environment will have a great impact on the environment. Therefore, the construction mode of high efficiency and low energy is urgently needed, which is the trend of construction technology development, and the inevitable road for the sustainable development of construction industry. The sustainable development of the construction, we will be called green construction technology. In fact, in the past construction process, reduce construction noise, reduce material loss and so on have been able to cause the attention of construction enterprises. But green construction to the "environmental protection" as the overall role in the whole process of construction, to the construction of the whole process of the impact on resources and the environment as much as possible small, this is important performance of the idea of sustainable development in construction, is the green building technology applications.
2 renovation phase of the management
The general contractor will need to decoration, the greatest impact on the environment factors to identify, and then conclude the related environmental protection measures. Subcontracting units made in accordance with the general contractor of the initiative, to the greatest impact on the environment and key control factors. And the total package units to related methods on the construction work is not enough green behavior let subcontractors use and protection measures for, for environmental requirements are not up to the standard of decoration materials, to return.
2.1 control pollution
For those who want to carry out a large number of welding operation, welding, there will be a lot of waste slag and smoke generated, and the welding will produce a lot of light. Therefore, when the welding of the welding dust, to carry out a closed container collection operation, so that dust can be effectively controlled. To prevent welding produced light pollution amount measure is: welded construction personnel must wear welding mirror, let the electric arc to minimise the damage to the human body, will wear welding gloves, welding when skin burns risk effective control; but also a light blocking device, reduce effect of arc on the surrounding environment.
2.2 noise control
Some decoration company set up their own processing plant, to prior to pretreatment of raw materials, or the raw materials to processing and factory transported to construction and effectively avoid the construction site dust and noise pollution. In the process of metal cutting, there should be a closed processing sites, to avoid noise pollution, reduce the impact on the environment. The person cutting the need to wear a dust mask to protect. Wet cutting can also be used to reduce dust and machine wear.
2.3 control the dust
In the paint on the wall brush before, must be before the painted wall putty to be polished, so that the wall is more smooth. The current level of construction can only be carried out, so when grinding is bound to produce a lot of dust. So how to reduce the dust of this process is the urgent need to solve the problem.
2.4 control of construction waste
Decoration raw materials produced by the waste necessary to make sub units to be classified and collected, and then back to the supplier of raw materials, can also be sold to the formal acquisition of waste. Those in the renovation of the environment harmful to the waste, to all of the recycling, and then to the company to be a regular recycling.
2.5 the use of environmental protection decoration materials
Decoration is the use of raw materials are very much in the construction or after the formal operation, will be more or less contact with people, so to be effective control of these raw materials. Used in the decoration of materials must be friendly to people and the environment of the decoration materials, the content of its harmful ingredients must be under the relevant standards.
3 section material and material resources utilization
3.1 wall materials used in the production of construction waste
The old buildings will be removed after the demolition of a lot of construction waste, if the direct landfill will not only pollute the environment is also a waste of a lot of resources, which will make the city's environmental pollution. In the construction of the building should be a lot of wall materials, to produce the wall material is bound to lose a large number of natural resources, so that the environment was destroyed. The use of construction waste to produce wall materials has been widely used, the products produced in this way is also in line with the requirements of the national standard. Therefore, the use of construction waste to manufacture the wall material is also an important measure of environmental protection construction decoration.
3.2 section material control measures
In the masonry and plastering mortar, should pay attention to the purchase rate, can not let the mortar placed too long time. This will increase the difficulty of the construction, so the need to improve the current process, so that the amount of ash dropped. To control the plaster layer thickness, which can reduce the use of plastering mortar, saving raw materials.
3.3 the use of ready mixed mortar technology
The use of ready mixed mortar is bulk cement; can of water of power plant and steel plant of abandoned property is one of the material, used to reduce the amount of cement used, reducing the amount of ready mixed mortar cement, in addition to a water reducing agent, which can reduce the production of mortar of cement and water use; ready mixed mortar production strictly in accordance with the provisions of the ratio; therefore, the mortar can reduce energy consumption, makes the environmental impact to a minimum, this also is the construction industry is a huge boost.
3.4 bulk materials such as construction material control measures
Decoration when the sub contract is generally to calculate the total amount of the project contract, the general purchase and processing of raw materials will be sub contracting units to be contracted. Subcontracting units will not allow the purchase of materials in the transport or processing, there is too much damage, transport and processing of raw materials will reduce the amount of raw materials to increase the cost of subcontracting units, reducing its economic benefits. General decoration company will set up their own company's design department, there will be about their company's processing plant as well as the decoration of raw materials warehouse. Will they subcontract the project to be secondary deepen design, for example of wire CAD deepening design, and then make a decision scheme, bulk will use CAD be global layout, to determine treatment bulk volume and the number of how many, before by the company's own design of the processing plant to be processing, can also let the suppliers strictly in accordance with the requirements of the company be processed, and then sent to the construction. But should pay attention to is that the bulk of the cutting size must be very accurate, otherwise it will because the size is too small and not be able to use, or because it was too large to re cut, makes raw material is wasted, but also makes the energy is wasted and the environment pollution, the bulk material of the uniform distribution, can effectively reduce corner of the feeding amount, reduce the waste of materials, but also makes the noise and dust pollution is reduced.
3.5 control measures for subcontractor living water
Because of the general contractor will live inside a common construction area, so the general situation of living water to be respectively measuring the difficulty is very great, so most of the project will use in accordance with the subcontractor's staff check-in number of utilities charge, a room regardless of how many people live in, these people with the water and the number of electric, are not calculated, shall receive the same utilities. Of course, such a calculation can not effectively control the use of water for life. So the general contractor should equipment for water saving in the construction area, also can use rain water and bath water to flush the toilet, to make the waste of water becomes less.
4 decoration in the process of low carbon concept of value
4.1 maintenance and update of materials and equipment
Usually case, the service life of the raw materials used in the decoration and related facilities needs more than the building service life longer, therefore, to make the building in the general service life in all its functions can be normal operation of the, must be timely replacement and updating of related raw materials and facilities. In of decoration design is to first clear is the use of raw materials and related facilities used how long life, as well as to how long a time of renewal and maintenance of it. Only in this way can we obtained more effective and energy-saving solutions, and ultimately achieve can reduce the construction of carbon dioxide emissions, reducing the greenhouse effect.
4.2 removal of related materials and reuse of carbon emission
Materials related to the architectural decoration in the process of demolition and reuse of carbon emission amount is the main factors of low carbon effect of architectural decoration, and related materials of energy consumption and demolition of the operation of the machinery and equipment, construction technology and removal quantity is directly related to the. Therefore, in the process of material removal through the low carbon concept must be standardized, efficient, energy-efficient construction methods to eliminate the fundamental problem of environmental resources. For after the removal of the materials and equipment, recycling and reuse of materials should be carried out timely processing and recycling for example waste materials can be used as roadbed filler partly for disposal of. In the future, it is possible to classify and deal with the non recyclable building materials and garbage. In short, through the recycling of building materials to a large extent, the river to reduce carbon emissions in the process of building decoration decoration.
5 concluding remarks
Energy saving and environmental protection is the pursuit of the construction industry a engineering philosophy, and low-carbon green engineering construction is a long process, need the attention the relevant laws and regulations of the state constraints, the construction unit and the support of the masses and the owners. In the construction, make full use of existing resources, through the management and application of decorative materials and the construction of personnel staffing and scheduling, make the quality and appearance of the green building decoration to meet the design requirements, so as to ensure that the decoration engineering construction in green and low carbon construction quality.
