[BIFE Eng ver.] Why do we need facade engineers? 1/3

(1)  Function concentrated

 

 Why do we need a special field called façade engineering? Façade, directly in contact with the external environment, performs a variety of functions. As functions are concentrated in facades, engineering knowledge from various angles such as the structure and environment is essential. As a result, the facade shows a complex configuration. For instance, the complexity of facade detail drawings reflects the concerns of facade engineers about its functions.

 

Section sketches for aluminum and PVC window frames.

 Let's take the example of window frame details. The above sketch shows window frames of aluminum and plastic. The plastic used for windows is a material called PVC, which is mainly used in homes and small buildings in Korea. For both, it is hard to understand the section of the frame or the way the glass is inserted. Holes are punched here and there, and the shape looks very strange to people who have never seen it before. However, this uniqueness and complexity appearance of the window frame is the result of continuous development not only to block heat movement but rain and wind through window frames as much as possible. (The air layer is the most representative insulation material).

 

 Moreover, regulations are being strengthened to reduce the energy involved in cooling and heating. The primary solution to achieve this is to block heat movement as much as possible. So more and more complex frames with improved insulation, like the sketches above, have continued to be developed. Understanding these complex details and re-suggesting details according to regulations and building conditions is the role of facade engineers. Typical examples include window frames, but all other special details related to the facade are issues that façade engineers should solve.
