The energy-saving design from the building's perimeter structure is actually interlocked by factors like window opening, orientation, treatment and insulation materials. These factors affect the energy consumption from the building. The Silaya Research Business in Taiwan has conducted research within the external protective structure connected with office buildings in Taiwan, and analyzed the electricity consumption of various elements from the building's external protective system. The analysis results usually are as follows:
1 The window opening rate on the external wall is the most crucial factor for energy saving from the external wall. Reducing the window cutting open area ratio is the main means of energy conserving, but reducing the window opening rate must ensure and proper organic lighting, and avoid this psychological closure. However, for your glass curtain wall that pursues the transparency consequence, the energy-saving requirement could only be achieved by means of reducing the opening eye-port area and strengthening the heat-insulating design in the opaque place.
2 External shading and glass shielding will be the second most important reasons for energy saving connected with external walls. Glass products and external shading just about all affect the shielding fee. However, the installation of sunlight visors and sunshade is alot more effective than changing the actual glass material. The glass material could be selected from high reflectivity reflective glass and heat absorbing goblet (reflecting glass with exorbitant reflectivity will cause glare pollution), so choose the proper
insulated glass factory.
3 The building orientation factor may be the third element of the energy-saving design on the external wall (accounting for 13. 8%). A large patch of glass curtain wall ought to avoid the east as well as the west, and the long direction on the building should be put in a north-south direction.
The use of shading measures is not just a necessary means for energy-saving design of glass curtain wall buildings, but also a new necessary means for constructing design of high-standard magnifying glaas curtain wall buildings.
