The building industry is in constant change and the United Arab Emirates (UAE) is a leader in innovative solutions for green buildings. The standards used in achieving sustainable buildings, such as LEED, Estidama, have contributed to building structures that reduce energy consumption. More than 40% of the total energy is consumed by residential and commercial buildings as electricity. The strategies applied in a building in order to have low energy consumption vary depending on the region and climate. In the UAE, a country with a hot arid climate, these strategies have relevant importance. The aim of this study is to design an innovative parametric/dynamic façade in a new building, to be built on the United Arab Emirates University Campus, AL Ain, Abu Dhabi, UAE. The new structure is an additional library building (with additional functions to the current building). The design shall be based on the region’s architectural heritage. The modelling and simulation tools used are Rhino and plug-ins like Grasshopper. Furthermore, an optimization process of the parametric/dynamic façade is conducted. Based on the energy simulation results, the application of the innovative parametric/dynamic façade brings a reduction of 25% in the energy consumption of the building. In addition, the daylight improvement by the application of this façade is 44%. This research brings innovation in terms of the advanced tools used in calculating several parameters for the advanced façade and the process from concept to modeling and simulation. These findings are promising for regional industry due to the advanced tools and methods used. Moreover, it shall help the local authorities such as Abu Dhabi Municipality achieve the sustainability goals 2030.
Over the last 50 years the cities in the United Arab Emirates (UAE) developed rapidly. Building stock is very diverse in the country and varies from one city to another. While Dubai has a large stock of skyscrapers, Abu Dhabi has more of a mix of high-rise and mid-rise buildings, and AL Ain—mainly mid-rise and low-rise buildings. The aim of this study is to evaluate the energy consumption of a retrofitted building versus a new building designed based on advanced tools of calculation. The new design is based on sustainability principles of design as well as the advanced parametric design where the analysis considers several parameters. This evaluation is a comparison between the current building, a retrofitted building, and a new design of the same build-up area. This analysis will be conducted considering local sustainability standards such as Estidama and Abu Dhabi Realm Manual. The methodology starts with the building selection process which consists of the selected building as part of a villa compound done in the city of AL Ain. The site measurements are the following step. This file is used for the boundary conditions of the models. The following step involves energy simulations. The models were prepared with several scenarios as per the predefined analysis and run for simulation. Grasshopper throughthrough rhino were the softwares used for energy simulations and applied design. Therefore, energy saving was calculated based on the selected matrix. The results show that the selection of the shape of the building and application of sustainable measures in the early stages of design can save 32% of energy, and a retrofit of the current building would save 9% of the electricity used.
