Application of double skin façade (dsf) and electrochromic glass in buildings in tropical climate

Wicaksono Muhammad Satrio, Purwanto L. M. F.

Vol. 15, no. 4

81--90

One method in terms of architectural technology used to minimize the negative impact of overheating is to design a building with double skin façade and integrating it with electrochromic glass. The purpose of this research is to reveal whether the use of a double skin façade and the application of electrochromic glass would be preferable for buildings in tropical climates, in terms of obtaining aesthetic points while not having to sacrifice thermal comfort nor committing energy waste at the same time. The data in this research is obtained with qualitative - descriptive comparative method, which is applied for room temperature measurement with a computer simulation software, based on pre-existing theories, reference standards and material specifications from existing manufacturers. The results of this study conclude that the application of double skin façade in a building does make a significant contribution to achieving thermal and lighting comfort. Both profiles of space reduction with the use of electrochromic glass in buildings in tropical climates are able to reach ideal temperatures in comparison to when ordinary glass material is applied. And third, it is proven that the double skin façade technology and applying electrochromic glass on a building can provide significant energy efficiency for long-term projects.

Study of electrochromic (EC) and gasochromic (GC) glazing for buildings in aspect of energy efficiency

Vol. 14, no. 3

27--38

The paper analyzes the impact of switchable glazing: electrochromic (EC) and gasochromic (GC) on the energy efficiency of the building. Using the analytical and comparative method, the energy-relevant EC and GC glazing features were defined. Secondly, experimental studies on the energy-saving role of EC and GC glazing in various climatic zones were analyzed. The paper aims to define this role. The analyzes were referred to the thermal and lighting aspects. Comparisons were made between the EC and GC technologies, as well as with traditional - “static” types of glazing. The analysis showed differences in the technical characteristics of both technologies. Despite the differences, the results prove a beneficial effect of EC and GC glazing on the reduction of usable energy consumption in the building. The impact is most significant in terms of relieving the cooling and air conditioning systems. In this field, EC glazing was determined a more favorable technology. Further detailed research is required, focusing mainly on the lighting aspect for moderate and cold climate zones. The research was summarized with a collective evaluation of the energy-related role of EC and GC glazing.
