The Impact of Internal Dynamic Facades on Energy Saving
The British University in Dubai (BUiD)
As the world’s environment is suffering from excessive problems people are facing nowadays, increase in levels of CO2 is one of these problems. The building industry is responsible for 40% of greenhouse gas emissions, and multiple solutions are currently taking place to solve these issues. In the construction field, window shading is already an old and common habit that has been used for a long time. Manipulation in these shadings is what is creating new challenges to reduce energy consumption in a building and therefore save the world. The study focuses on the use of different techniques that act as window shading devices to save energy such as automatic shading, manual shading, and the introduction of glass tinting. All of these are compared to each other through the use of simulation of a typical office space located in the Bank of Housing, Amman, Jordan. The results show that manual shading all in all saves up a total energy of 57.01%, automatic shading saves up 43.08%, and tinted shading saves up 37% of total energy taking into account that all are compared to Base Case scenario. In the case of economic analysis, manual shading requires a payback period of 5 years. Tinted shading requires 15 years while automatic period is the least economical with a payback period of 17 years. The purpose of this study is to show which technique saves up more energy and cost. In this case, it is proven that manual shading saves up the greatest amount of energy when comparing it to all other scenarios. This means that in this case in particular, automatic shading or tinted is not favorable.
