Nowadays, there is a worldwide need for sustainable buildings because of the dramatic increase in building energy consumption. Due to the spread of building towers, and since they are a huge energy consumer, it is urgent now to consider a sustainable strategy in designing tall buildings. Building facades are the key aspect of improving the energy performance of the building in general and specifically in towers, by decreasing the heating and cooling loads. This research investigates the role of innovative building facades and intelligent skins in reducing heat gain and heat losses, which promote the energy performance of buildings, and how much energy can be saved. It shows different sustainable rating systems such as the Jordanian Green Building Codes (JGBC) and Leadership in Energy and Environmental Design (LEED) to evaluate the energy performance of the building and tries to figure out the potential of getting prerequisites points and define its role in enhancing the building performance. The research studies the Rotana Tower Hotel in Amman City, and it is based on a combination of descriptive, analytical, and empirical approaches to understand and achieve the research goals and objectives and formulate the research questions. Weather Consultant Program, Revit software, and Green Building Studio Insight 360 for simulation are used to study and analyze two different case scenarios, by applying different façade systems, then evaluate each scenario, and compare them to the base case in terms of energy and CO2 emissions saving aspects. The results and findings show a distinctive improvement in the energy performance of Rotana Tower after applying the efficient glass façade; 47% reduction in energy and a 46% decrease in carbon emissions, on the other hand, 74% in energy savings after integrating photovoltaic glass on the façade.
