Keywords: residential energy conservation and environmental protection new energy
The energy problem has become the focus of the remarkable problems, the energy shortages have seriously restricted the economic development. The residence is human life on the important place in residential building construction and use process, will consume large amounts of energy and resources. With China's rapid economic development and people's living standards, residential energy consumption grow. According to statistics, residential energy consumption is mainly used for heating, and at present mainly by using the methods of coal, gas to heating, and can cause severe environmental pollution. At present, China's winter heating energy consumption per unit area is with latitude than developed countries 1 ~ 2 times higher, this, indoor temperature also can keep in 13 ℃, especially in the cold region in China, heating energy consumption will be more big, cause the pollution of the environment is more serious. So, realize the modern residential building energy conservation and environmental protection, in China's energy is to alleviate the pressure, reduce the pollution of the environment of important ways.
1 the definition of residential energy conservation and environmental protection
"Energy conservation and environmental protection the residence" or said "the green house", belongs to the sustainable development of architecture, it is high efficiency and low energy consumption and environmental protection and energy saving, healthy and comfortable, the ecological balance of high quality residential building, is considered to be the future housing construction development direction. In residential energy-saving character, heating energy saving is only part of the energy saving in energy saving residence should also include the water, electricity, gas, such as heat energy saving and all kinds of building materials, products of the save, further analysis and new technology, new technology, new material, new energy application. As for protection, covers the scope is more widely. So must will "environmental protection, energy saving residence" development and construction as a system engineering, and seek for the best to save energy and in harmony with the environment, the minimum degree environmental harm, for the sustainable development of ecological environment.
2 in residence of the present situation of energy conservation and environmental protection
Our country is in the construction engineering construction rush hour, and civil building construction were in full swing. In the construction of the modern residential buildings, the ecological technology, development and use of renewable energy, save non-renewable resources, improve the indoor thermal environment, improve living comfort, maximum limit save resources (energy saving, section, water saving, saving material, etc.), protect the environment and reduce pollution, providing people with health, apply and efficient use of space and natural and harmonious coexistence of residential energy conservation and environmental protection has become a trend. At present, our country's energy conservation and environmental protection residential construction exist in the following problems:
(1) building design and construction technology level is low
China's energy conservation and environmental protection building development than developed countries lag decades, energy conservation and environmental protection building design, construction is still not fully systematization and standardization, the relevant standard time later on, but with the state council decree no 530 the civil building energy conservation ordinance "releasing energy conservation and environmental protection residential construction will gradually standardized. Residential building structure design and construction are still developing, the technical level to be further improved.
(2) the construction workers in energy saving consciousness is not strong
At present, our country construction workers in energy conservation and environmental protection consciousness is not strong, energy conservation and environmental protection professional technology level is low. Because China's energy conservation and environmental protection residential building started late construction, construction units have been used to the conventional form of construction, energy conservation and environmental protection of new residential building learn fewer; In addition, designers to energy conservation and environmental protection building design is more strange, concept failed to turn.
Therefore, the government should strengthen the propaganda, enhance people's energy conservation and environmental protection consciousness.
The modern residential energy conservation and environmental protection technology application
The ideal energy conservation and environmental protection residence is in the lowest energy consumption, under the premise of time to be able to keep indoor comfortable, in each season, each can reasonable use solar energy area control; Can realize indoor ventilated take a breath. At present, realize the residential building energy conservation environmental protection the main approaches are: to reduce energy consumption, improving energy efficiency; Reduce the energy loss building structures; Reduce the operation of building energy consumption. To adopt new technology, new energy conservation and environmental protection material has a decisive role.
3.1 reduce energy consumption, improve energy efficiency
As people living standard rise, the living environment of comfort requirements also more and more high, inside the residence requirements can be warm in winter and cool in summer, dry wet moderate, ventilated smooth, these requirements, often are through the consumption of energy to can be realized. From the aspects of managing the sources of energy to consider, should improve heating (refrigeration) system efficiency, reduce energy consumption. This requires, high new technology to achieve the purpose of improving efficiency. At present, in the heating system can be used in the following three technology: (1) reasonable distribution network flow can be used for computer and intelligent instruments, improve the quality at the same time in heating and save the energy; (2) in the radiator mounted on heat distribution form and the temperature regulator, so that users can be adjusted according to the actual need, avoid the waste of energy; (3) heating pipeline will be by using new thermal insulation material package, reduce the heat loss.
3.2 reduce building palisade structure energy loss
Reduce the energy loss building palisade structure mainly from the outer wall, doors and Windows, the roof of the three face, should development and application of high efficient and economical heat insulation, heat preservation material, USES the advanced feasible construction technology, so as to improve the distribution of the structural and insulating performance, heat preservation performance and the sealing performance.
The energy saving technology 3.2.1 exterior wall
Wall is the subject of retaining structure, and now it is to use commonly composite wall instead of a single wall structure to achieve energy conservation and environmental protection requirements. Composite wall bearing structure general use of the reinforced concrete or piece of body materials, and heat insulation materials and compound, or in the frame structure with thin wall materials to heat preservation, heat insulation materials as a wall. At present, our country is usually out maintenance structure construction is finished, then put a layer of heat preservation material, improve the thermal performance. Because of the low price of polystyrene and have excellent physical performance, so has been widely used in the external wall thermal insulation. The plug-in technology is used, the heat insulating materials used mortar paste, hanging in exterior wall above, then daub wipe cracking mortar, pressed again into the glass fiber grid cloth formation protection layer, finally add make decoration face.
The energy saving technology 3.2.2 doors and Windows
The doors and Windows has ventilation, lighting and retaining, and other functions, but the energy loss is the main door window position. Modern architecture for greatest daylighting and ventilated, the size of the doors and Windows are getting more and more serious. It is the energy saving water put forward higher request. At present, mainly through the Windows and doors of the heat insulation materials to improve performance and improve its sealing to realize the energy conservation and environmental protection. Main measures are: improving the capability of heat preservation material doors and Windows; Enhance residential outside the window air tightness, to reduce the internal and external air exchange; Control residential window than wall; Set up "temperature damper area".
3.2.3 roof energy saving technology
The roof of the insulation, also is an important part of energy-saving measures. The main energy saving measures in the roof is roof surface set the thermal insulation layer, let it in different regions, different conditions play its different effect. Heat preservation main measures are: (1) the coefficient of thermal conductivity small, density is small of the heat preservation material in the roof of the waterproof layer set below form thermal insulation layer. (2) in the roof waterproof layer polystyrene foamed installed above. Roof insulating cooling measures: roof water storage, timing hydraulic looms and built on stilts ventilated, roof greening, etc.
3.3 reduce the energy consumption of the construction operation
Lighting, cooling, heating is live in building energy consumption of the main parts, reduce the energy consumption of residential building realization of energy conservation environmental protection has a pivotal role. The main way is, as far as possible the use of natural light, and promote the use of high efficiency and energy saving lamps and lanterns, aisle, fellows using sonic switches etc. The key is to strengthen people's energy conservation and environmental protection consciousness, from save every once electricity, save every drop to start, eliminate all cause a waste of energy behavior.
3.4 development of new energy use
People in saving not renewable energy at the same time, still should exploit other new sources of energy, such as solar energy, wind energy, water power, tidal power, and so on. In recent years, coal, fuel and gas resources of the growing tension, the solar energy as a clean, environmental protection, infinite energy, with a great development potential use, especially in the house on the application of building energy efficiency. Is mainly embodied in the application of solar energy water heater, in our country, the solar energy water heater has generally, widely application. If the solar energy to make full use of, will be completely solve the problem of energy crisis in the world today.
3.5 building energy saving the development of new materials
Building energy conservation of the development and utilization of the material basically has: the external wall thermal insulation and facing system (EIFS) application, building preservation heat insulating board system (SIPS) application, building preservation heat insulating board system (SIPS)
Application. These new building energy conservation and environmental protection material in residential buildings can be used in residential construction of energy conservation and environmental protection to bring twice the result with half the effort, therefore, we will vigorously promote the application of the new material.
