Refers to the buildings in the site selection, planning, design, construction and use process, through the reasonable planning and design, energy-saving building materials, products and equipment, implement building energy efficiency standards, strengthen the building of energy-saving equipment running management, reasonable thermal performance in the design and construction of retaining structure, improve the heating, refrigeration, lighting, ventilation, water supply and drainage, and the operation efficiency of pipeline system, and the use of renewable energy, in guarantee the quality of building use function and the indoor thermal environment under the premise of reducing building energy consumption, reasonable and efficient use of energy. If you stick with the low level of energy saving design standard, it will leave a heavy burden of energy consumption and management difficulties. Huge building energy consumption, has become a huge burden of the national economy. So the construction industry overall energy saving is imperative.And define the meaning of building energy efficiencyThe energy dissipations of the building in use process, known as the building energy consumption, a large proportion of the total energy consumption in society. Chinas reform and opening up 30 years, created the world the human miracle in the history of architecture: 20 years from 1985 to 2004, the completion of the construction area of 10.56 billion m2, accounts for about 1/4 of existing building area, predict 2020 will also be new construction area of 30 billion m2. However, the existing buildings in China, more than 95% is high energy consumption construction. In 1992, the building energy consumption accounts for 15% of the energy consumption of the whole society, at 27.5% in 2000 and 2020 will increase to 40%, if coupled with the transportation and the loss of raw materials, etc., building energy consumption could be as high as 50%. It reflects the improvement of living standards of urban and rural areas in our country, also reflects the high speed development of our countrys construction and energy demand situation. Due to the building energy consumption in total energy consumption accounts for a significant proportion of building energy efficiency has become the mainstream in the world wave of energy saving is one of the building energy saving technology has become one of the key point of the development of the architectural technology anywhere in the world.2 real implementation of building energy efficiency design2.1 the overall design and the external environment of energy savingIntegral and the external environment design is based on the analysis of buildings surrounding climate, on the basis of environmental conditions, through site selection, planning and design of the external environment and body orientation, make the building to obtain a good external micro climate environment, achieve the goal of energy saving.2.1.1 the reasonable locationSite selection is mainly according to the local climate, geology, water quality, the terrain and the surrounding environment condition factors such as comprehensive condition to determine. In architectural design, both to keep building throughout its life cycle is suitable for micro climate environment, create conditions for building energy conservation, and dont destroy the balance of the overall ecological environment at the same time.2.1.2 reasonable external environment designAddress was determined in the building, should study the micro climate features. According to the requirements of architectural function, should through the reasonable external environment design to improve the existing microclimate environment, create favorable environment, building energy conservation main way is: (1) decorated trees, vegetation around the building, can effectively keep out dust and purify air, still can shading, noise reduction; (2) to create artificial natural environment, such as in the construction set up near the surface, water is used to balance the environment temperature, sand and collecting rainwater, and so on.2.1.3 reasonable planning and shape designReasonable planning and building design can effectively adapt to the harsh climate environment. It including the overall dimension and architectural shape and architectural form combination, determination of sunshine and respect such as.Sunshine and toward the choice principle is winter can get enough sunshine and to avoid the dominant wind direction, can make use of natural ventilation and prevent solar radiation in summer. However, building orientation, orientation and construction total plane design should consider the various factors, building social history culture, landscape, urban planning, road, environment condition such as restriction, in order to protect the buildings to meet the summer heat and winter heat preservation is difficult, therefore, can only weigh the various factors between the gain and loss, to find a balance point, choose the best orientation and construction of this area is better toward, east-west sunlight should be avoided.2.2 monomer of energy-saving designMonomer of energy-saving design, mainly through to various parts of the building energy-saving construction design, building interior space of reasonable space design, as well as some new energy-saving building materials and equipment design and selection, to better use of existing building external climate, environmental conditions, in order to achieve the effect of saving energy and improving indoor microclimate environment.2.2.1 building energy-saving construction design of each partBuilding energy-saving construction of each part design, mainly in the meet the requirements of it as an essential part of the building, based on each part (roof, floor, walls, doors and Windows, etc.) in the modeling, structure, material, etc to further design, make full use of the building external environment, climate conditions, to achieve the effect of saving energy and improving indoor microclimate environment.1) the energy saving design of the roof. Roof is a building with outside air contact is an important part of the main energy saving measures are: (1) use slope roof; (2) strengthen the roof heat preservation; (3) according to the needs, set the thermal insulation roofing (overhead insulated roof, water storage roof, roof planting, etc.).2) the energy-saving design of floor layer. Mainly using the structure in space, as well as to the floor condole top modelling and design. If the circulating water pipe layout in which, the summer can use cold water cycle to reduce indoor temperature, using hot water circulation to keep warm in winter.3) building outer wall energy saving design. Wall energy saving design in addition to adapt to climate condition ready for heat preservation, moistureproof, heat insulation, and other measures, should also be reflected in can improve microclimate environment conditions on the special structure of such as cold areas of sandwich wall design, passive solar houses various heat storage wall (water wall) design, Baghdad region in order to adapt to the local hot dry climate conditions in the wall of the tuyere design, etc.; In Malaysia, penang state MennamUmno Yang scripture design buildings, walls, and a kind of special structure design pave the wind wall, the buildings on both sides of the opening balcony, openings on both sides of the outer wall two DangFengQiang, make the two ventilation wall to form a trumpet-shaped pocket, will wind shop is caught in the balcony, and then into the air through the balcony door opening size control, form the air locks, can effectively control the indoor ventilation.4) building energy-saving design of doors and Windows. According to statistics, in our country existing energy intensive building 40% of the energy is dissipated through the doors and Windows. Therefore, solve the problem of the doors and Windows energy saving is very important. The energy-saving design of doors and Windows should consider: (1) control architecture is different toward the window wall area ratio; (2) set the sunshade measures specified in the standards for energy conservation in our country, the region with hot summer and warm winter, hot summer and cold winter areas and cold areas in the cooling load of building external Windows (including the transparent curtain wall) should be set up outside shading; (3) according to the need to properly organize ventilation doors, Windows, try to use natural ventilation; (4) the cold, cold area construction of outside door set cross-bars or take other appropriate measures to reduce the infiltration, other parts of the building outside door and heat preservation and heat insulation measures should be taken; 5) choose high-performance building doors and Windows and curtain wall technology, building doors and Windows and curtain wall to change the negative thermal insulation of single energy saving ideas, the energy conservation and rational utilization of solar energy, underground hot (water) can be combined, wind actively choose energy saving and energy (can use solar energy, cold, wind, geothermal) combining the doors and Windows and curtain wall products.5) building palisade structure energy efficiency design in details. Details of the energy saving design for the structure of the overall energy saving is also very important, from each of the following areas: (1) hot mouth reliable insulation should be taken of parts of the bridge and broken bridge; (2) the outer wall and relative components attached to the wall components, such as balcony, rain cover, by exterior balcony column board, air conditioning separate-bodied air-conditioners shelf, pilaster, convex Windows, decorative thread partition and thermal bridge insulation measures should be taken; (3) around the window of the lateral wall, should be heat treatment; (4) the gaps between the door and window frame and wall body, high efficiency heat preservation material should be adopted in; Around 5 doors, window frames and the gaps between the plaster layer, appropriate USES insulation sealing materials and sealing paste sealing, interface craze, avoid different materials affect the thermal performance of a door, window; 6. Using full glass curtain wall, partition wall, floor slab or beam and curtain wall, the clearance between the should fill the thermal insulation material.2.2.2 rational arc
