The usages of building
The factors related to the construction purposes are the running time, internal heat load (in the running time or beyond the running time), indoor comfort requirements and user behaviors. In this regard, the decision of the specific curtain walling design also depends on whether the building is the administrative building, corporate headquarters, hotels, shopping centers, cinemas, cultural or educational buildings, museums or galleries, theaters, hospitals, production facilities or airports or train station. The decision is also affected by the use of space and space capabilities, as well as the impact of the basic shape and height of the buildings. Current design is consist of a separate room and open room (office, conference room, reception room, sales area) or space can be flexible arrangement? Lounge (multi-storey) the atrium connected buildings in different regions channel? Stairs and corridors - especially those that bear the function of the means of escape staircases and corridors. But the equally important thing is where to build the buildings.
The external factors affecting the curtain wall
The external conditions that mostly affect the curtain wall of the building are the common external air temperature and solar radiation level. Wind speed and direction also play the important roles. The location of the building also decides the noise and humidity levels, and the degree of freedom of the building's exterior design is also affected by this project, that is whether it is the new construction or renovation or refurbishment project.
The importance of the flexibility of building
Because the changes in our social system, grade, and living and working are faster and faster, the flexibility of the building will be more and more important. This is true, in particular, for a cost-effective building with the long-term for with restricted period must be as short as possible, building maintenance costs, modified (if new users have different requirements) and transformation (such as the addition of new energy-saving facilities or improve comfort facilities) cost low. Cost-effective buildings that are configured only meet but before requirements. Requirements change can quickly and easily make the appropriate changes, and will not produce as much as possible the destruction of double skin curtain wall. Architects, project managers and planning experts can make considerations from the aspect of planning, including the company should pay close attention during work (general contractors and industry experts) to take advantage of this and workload. All construction professionals should do its utmost to reduce their own risk, even when they suddenly had the inspiration to show that the best ideas. This stage will ultimately lead to a detailed set of design specifications and binding. It ensures that every staff forms a concept, which can not only avoid misunderstandings, but also can reduce the risk and cost.

Introductions for Double Skin Curtain Wall
The double ventilation curtain wall is applied widely
The double ventilation curtain wall appeared in Europe in the 1990s, and has been applied gradually, which applied more widely especially in Germany. It plays a big role in increasing the curtain wall insulation, heat insulation, sound insulation function. China is also designing and constructing the double skin curtain wall.
Double skin facade classification
Double glazing curtain wall is mainly divided into inner and outer loop system, which has similarities and differences. The common characteristic is form greenhouse effect between the double glass, and exclude superheated air in greenhouse in summer outdoor, discharge the solar thermal control into the room in winter, saving a lot of energy in the summer and winter season.
The main features of the inner loop double skin curtain wall structure: 1. Its structural design can use steel portal frame thermal break or the unit thermal break form; 2. Generally, the outer glass selects hollow steel, inner glass chooses monolithic steel. 3. Using coercive measures, electric control channel system to exclude most of the hot air in bunk closed channel outdoor in summer daytime. In winter, spread the greenhouse effect heat storage into the room through the pipeline loop system, to save energy. Its wind between the inner and outer surfaces of the cavity thickness design is narrow, which is generally within 120-200mm (individually about 400mm). 4. Need for additional sash channel for natural air into the interior room. 5. Ease of cleaning dust between the double glazing. 6. Use less material, so the cost is lower. 7. Need electronic drive ventilation, energy saving is lower than the outer loop structure.
The main features of outer loop double-layer glass curtain wall structure
1. The structural design can use the outer layer framework, the form of unit or point connections; the inner frame thermal break or unit hollow glass thermal break form. 2. Generally the outer glass selects monolithic or laminated toughened, inner glass selects hollow steel. 3. Use natural "Chimney" effect, exclude hot air from the greenhouse to the outdoors in summer day, please note that the "chimney" effect in the different floors is different. 4. The cavity thickness of between the inner and outer layer design is thicker, making it easy for the cavity personnel between inner and outer layers to enter the cleaning work; 5. Does not require additional special equipment for natural air into the window and inside the house, the outer layer curtain wall design has air inlet and outlet; the inner curtain wall is designed to open a door or window. Pay attention to prevent the entry of sand dust, channel lower settings outside air into the exhaust port after the exchange of the air inlet of the cavity and the upper hot air. 6. The dust between double glazing should be considered for easy cleaning 7. Use more materials, so the cost is higher.

PV Curtain Wall is Significantly Energy Saving
Photovoltaic plays an important role for the energy saving policy
The use of photovoltaic (PV) is not limited to power generation, in fact, it also plays an important role for the energy saving policy. Especially in daylight control, translucent photovoltaic provides a wide range of space for curtain wall application. The transparency of the crystalline solar module depends on the distance between each of the battery, the closer the battery, the higher is the total PV output of the panel. In addition, a very close battery arrangement can reduce the amount of sunlight entering the building, in turn reducing the energy consumption due to refrigeration / air conditioning in the summer. But the architects usually do not consider optimizing the efficiency of photovoltaic curtain wall, but tend to higher user comfort.
The energy saving effect of the energy saving effect is remarkable in the summer
In the process of a research project carried out by the German Karlsruhe Institute of Technology, scientists studied and compared the energy efficiency of three buildings installing photovoltaic curtain wall located in northern Brazil, Fortaleza, Florianopolis, in southern Brazil, and Frankfurt, Germany. All double skin curtain wall of the three buildings are equipped with embedded translucent crystalline solar cell windows. Because all photovoltaic windows have only 30% transparency, the energy saving effect is remarkable because the cooling demand reduces in the summer. At the same time, more energy has to be used for artificial lighting inside the building. "But we've installed lighting control system to reduce this effect." EveliseDidoné, one of the Karlsruhe Institute of Technology researchers explained.
Different approach to control curtain wall transparency
A completely different approach to control curtain wall transparency is the use of dye-sensitized solar cells (DSCs). Different from ordinary silicon solar cell panel, the DSC photosensitive layer uses the photosensitive dye to convert sunlight into electricity. In fact, organic photoactive layer for the DSC is very thin, and the selection of different colors and the thickness material can manufacture the solar panels with the different level of transparency. Rossella Corrao from Department of Architecture of the University of Palermo, Italy explained: "compared with 20% efficiency of the silicon plate, the DSC module is only 8%, but compared to the crystal plate and the same power, they can actually produce up to 15% or more of energy each year. The reason is that the DSC module is more effectively under low light conditions. The silicon system differs in that DSC the efficiency does not depend on the angle of incidence light. Thus, DSC module is not necessarily to be positioned toward the sun, even if installed in a vertical or a horizontal direction, it will not lose efficiency.
The Seventh Energy Forum will be held in Bressanone, Italy, on December 6, 2012 -7
The above-mentioned scientists will present their research results on The Seventh Energy Forum entitled focusing the solar fa?ade held in Bressanone, Italy, on December 6, 2012 -7. The assembly will also highlight DieterMoor (Linz, Austria Arconsol) strategy on the optimization of the semi-transparent photovoltaic window performance and cost consideration, and LivioNichilio (University of Toronto) strategy to improve the energy efficiency of buildings through the use of integrated photovoltaic and thermal mirror glass curtain wall.
