Abstract
This dissertation discusses the design of double-skin facade (DSF), especially distance between two facades. It evaluates efficiency of DSF system based on a Vietnam case study. According to previous studies, the suggestion for range between two facades should be 0.22 – 2 meters. However, most researchers do not give the actual calculations in their researches. By using the Designbuilder software, this research tried to analyze the data from an actual building to draw the comparisons and conclusions in DSF ventilation system. In summary, my case study indicates that the optimal distance between two facade is 0.55 meters and it can be applied in similar designs and locations. The dissertation not only provides optimal distance between two facades but also provides suggestions in choosing materials, cavity design, ventilation and shading system design. The purpose of dissertation is to achieve the optimal design for typical double-skin facade building.
Besides, to improve the accuracy of thesis’s results, the parameters from outside environment have been focused. Climate features, opposite building, ventilation system and the building’s dimension are the four factors concerned, which affect the accuracy of evaluations and results. The results show the change of energy saving effect of double-skin facade design in comparison with conventional building. By using the dissertation’s results, designer can reduce the time required for calculations and improve the efficiency of their design.
Investment cost has been analyzed based on Vietnam case study building. However, this research does not give conclusions or suggestion for the economic efficiency of investment. The cost analyzing work serves for references and for further study’s purposes.
