ENERGY PERFORMANCE OF DOUBLE SKIN FAÇADE FOR HIGH-RISE RESIDENTIAL BUILDING IN ABU DHABI

The hot climate of the UAE generates unique challenges for architects and building engineers looking for energy efficiency in high-rise residential buildings. The use of glass building facades has been increased; this type of façade usually comes with a high air-conditioning cost due to the higher heat gain. To design energy-efficient buildings, it is essential to adapt the principles of sustainability and innovative transparent glass façade design into practice as the building facade is a major element in determining the amount of energy used in buildings. Construction details, methods, and materials of the residential building facade play an important role in controlling the energy performance level in buildings. This research aims to study, analyze and assess the type of glass and the suitable cavity between the transparent glass façade that can reduce the energy use of the highrise residential buildings in the hot climate of Abu Dhabi. This can be achieved by recommending different types of double skin façade glass types and the optimum cavity value which can be adjusted innovatively to the changing climatic conditions. The Double Skin Façade (DSF) is a multi-objective, high-performance envelope that can respond to the external climate to meet the internal load requirements (cooling, heating, lighting, or ventilation) and occupants’ need. The complexity of the DSF evaluation is related to the performance coupled with occupant behavior and occupant satisfaction. The main benefit of using DSF is to investigate the thermal performance of DSF in High-rise residential buildings in a hot climate. In this context, the study focuses on design principles of a double skin façade implementation details, including building material and construction technology to help architects and engineers reduce energy in high-rise residential buildings. In this research, the data was collected through a survey to define the research problem. The online survey was distributed to the residents of the selected residential tower. In addition, based on the literature, the data were analyzed using qualitative and quantitative approaches to reach the final results. The collected data was studied and analyzed about the following variables: a) the cavity, and b) glass types and their u-value properties. Each variable was explored according to the theoretical framework of the prior studies. However, based on the analysis and feedback received from residents, the design of the selected case study was modified and analyzed accordingly. In addition to the information from other official resources such as the AD municipality archive, the base case was tested by Energy Plus simulation software. The study concluded that the optimum DSF design greatly impacts energy efficiency in high-rise residential buildings. The existing data was modeled, and the results were compared with the new model results for each variable. As a result, the optimum double skin façade with a 35 cm cavity with double glazed single skin layer in the interior and a Low-E double-glazed single skin layer as an outer layer, this selected DSF reduces the energy consumption by more than 30% and reduced the AC energy consumption more than 25%

Optimizing Energy Efficiency in High-Rise Residential Buildings in Abu Dhabi’s Hot Climate: Exploring the Potential of Double Skin Façades

This study investigates energy efficiency in high-rise residential buildings in Abu Dhabi, where the increased use of glass building façades has led to increased air-conditioning costs due to heat gain. The research focuses on evaluating the type of glass and the appropriate cavity between glass façades to minimize energy consumption while incorporating sustainability and innovative design principles. To achieve these objectives, this study employs a Double Skin Façade (DSF), a high-performance façade that adapts to the external climate conditions to fulfill internal cooling load requirements and meet occupants’ needs. Data were collected through an online survey distributed among residents of a selected residential tower, and a combination of qualitative and quantitative approaches was utilized to analyze the gathered information. The selected case study was analyzed using Energy Plus simulation software using the existing data and available details. The analysis aimed to identify the optimal DSF design that significantly enhances energy efficiency. The findings of this study emphasize the substantial impact of the optimum DSF design on energy efficiency in high-rise residential buildings. Through modeling existing data and comparing them with new model results for each variable, this study demonstrates that a DSF with a 35 cm cavity, comprising a double-glazed single skin layer in the interior and a Low-E double-glazed single skin layer as an outer layer, can reduce overall air-conditioning energy consumption by over 25%. These outcomes provide valuable insights into implementing DSF as a solution to address the unique energy challenges presented by high-rise residential buildings in hot climates

Developing a Smart Grid System in the UAE: Challenges and Opportunities

The United Arab Emirates (UAE) is considered a strategic hub with a business-friendly free zone and a fast-growing economy. Globally, governments realize the importance of updating electric energy grids and establishing smart grid systems. The smart grid system (SGS) combines connected networks and the technological era, providing several methods to produce power from multiple sources. This research aims to analyze the UAE’s smart grid system’s development challenges through a survey intended to extract the most significant guidelines and issues affecting the progressive implementation of SGS in Abu Dhabi city, as these issues have not been thoroughly investigated. An in-depth empirical study was conducted to investigate the significant factors affecting the SGS through four aspects: nature, sponsor support, government responsibility, and market expansion. The “Policy Delphi” and a sophisticated survey tool called Qualtrics were adopted by a biased group of opinion specialists. The survey is intended to extract and analyze the most important guidelines and issues affecting the progressive SGS implementation in Abu Dhabi city. The findings of this study illustrated the drivers and barriers that affect the smart grid and the variables that should be addressed to enhance its functionality. Energy efficiency and loss reduction were ranked as the top driver with 32%. Operational and connectivity challenges were cited as the major obstacles to SGS implementation. Finally, the results indicate that smart grid technology can promote economic growth in the country by enabling a sustainable electricity supply
