【正文】 gn, architects need to building orientation, shape, direction optimization, in order to make full use of natural wind, sun and other natural resources to create the the same time, from programme design to the preliminary design, engineers need to constantly adjust the design simulation of building energy consumption calculation of quantification, airconditioning and equipment installed power, ratio of various influencing factors, in strict accordance with the results of the design calculations, finally provides the best energy saving elevation of the building design should be bined with the design and building external solar shading 1)to clear all kinds of external sunshading exterior shading settings and the position of the sun, building orientation are closely window shade, practice has proved that: the horizontal sunshade capable of shielding angle is larger, from the top of incident sunlight, applicable to the south window。vertical shading can keep the height angle is small, from the side of the obliquelight from the sun, applicable to the northeast, northwest and north to the window。overall shading of the level and vertical shading advantages, applicable to the southeast, southwest and south to addition, the baffle type sunshade, curtain type sunshade, sunshade for window sunshade, has very good results, but the building will have a certain for building wall and roof sunshade, more effective method is through the grid and green visor the continuous improvement of social economy, building shading technology has more and more intelligent, automation, high )from the ponent design and reasonable deal with sunshade and heat insulation traditional entity ponent level, vertical and sunshade and wall are connected, the absorbed heat will be passed directly to the exterior, but also constitute a half open space, sunshade ponent by solar radiation temperature rise, a part of the heat through the heat transfer from air to pass away, but due to other sunshade ponent of the block, but prone to accumulation phenomenon, under the action of wind through the window into the interior, which is not conducive to solution is in the horizontal sunshade ponent is chosen as the permeability of the ponents, such as metal louvers, concrete grid plate, so that the rising hot air can be effectively dissipated, reducing on indoor advanced double glass curtain wall system, in order to hot air rises, the two layers of glass curtainand the air between the interlayer is often a continuous whole, intervals are permeable metal ponents, to ensure that the hot air can rise up and take the , the sunshade ponent selection to meticulous research, constantly updated )should be arranged reasonably visor, avoid the influence of indoor air of the existence of the visor of buildings around the pressure impact, when the angle and direction of inconsistencies, wind speed will be reduced has proved that, due to the setting of the sun visor, indoor weaken 22% ~ 47%.Moreover, shade settings will have different effects on the the entity level visor is connected directly to the window top, air into the room after the rise, is not conducive to the room in the lower part of the the solid plate and wall between the increased gap, or in the upper part of the wall out of the visor vent, or the sun visor in each position some distance above the window, can make the airflow direction can be effectively regulated, so that the room is middle and lower parts are good ventilation, improving the fort of the indoor for the vertical shading, as the wind direction changes frequently, so the fixed vertical visor should ply with local summer prevailing wind to set the corresponding angles, and a better method is to use the adjustable vertical visor, construction maximum adaptation to climate departments and related design review department should increase pair of solar energysaving design review, where can use solar energy facilities, shall be proposed, through administrative means to force the implementation of solar this city be richly endowed by nature resources and energy saving 3 ending Building energy saving is a plex system engineering, involved in all aspects of the above mentioned three problems is just one part of it, in the city39。s energysaving design, they are often ignored or neglected, it will cause many design flaws, make the building energy consumption paper devoted to them all out to carry on the discussion, it is to benefit by mutual discussion, discuss jointly building energy saving design method, the design in the future study, try, accumulation, summed up, in the limited condition of the architectural function with art and technology to better integrate, make the architecture design in all aspects can embodiment of the principle of energy conservation, efforts to create a low cost, high efficiency and energy saving construction.
