The energy-saving design belonging to the building's perimeter structure is definitely interlocked by factors such as window opening, orientation, shading and insulation materials. These factors affect the energy consumption in the building. The Silaya Research Place of work in Taiwan has conducted research to the external protective structure with office buildings in Taiwan, and analyzed the electrical power consumption of various elements of the building's external protective composition. The analysis results are usually as follows:

1 The window opening rate with the external wall is the key factor for energy saving of the external wall. Reducing the window cutting open area ratio is a vey important means of energy protecting, but reducing the window opening rate need to ensure and proper healthy lighting, and avoid your psychological closure. However, to the double glass curtain wall in which pursues the transparency result, the energy-saving requirement can only be achieved by way of reducing the opening eye-port area and strengthening the heat-insulating design from the opaque place.

2 External shading and glass shielding is the second most important elements for energy saving regarding external walls. Glass materials and external shading most of affect the shielding rate. However, the installation of sun visors and sunshade is alot more effective than changing the particular glass material. The glass material is often selected from high reflectivity reflective tumbler and heat absorbing tumbler (reflecting glass with too high reflectivity will cause glare pollution), so choose the perfect reflective glass.

3 The building orientation factor is the third element of the energy-saving design in the external wall (accounting pertaining to 13. 8%). A large section of glass curtain wall will need to avoid the east as well as the west, and the long direction from the building should be used in a north-south direction.

Having shading measures is not only a necessary means for energy-saving style of glass curtain walls buildings, but also the necessary means for setting up design of high-standard glass curtain wall buildings.
