The "Building Sustainability Index for Dubai Electricity and Water Authority" study aims to develop a comprehensive sustainability index specifically tailored for the Dubai Electricity and Water Authority (DEWA). The index will serve as a tool to assess and measure the sustainability performance of DEWA's buildings, promoting a more sustainable approach to energy and water consumption. The study begins by conducting a thorough review of existing sustainability frameworks and indices to identify relevant indicators and best practices. By considering the unique context of DEWA, the index will be customized to align with the organization's goals, strategies, and operational practices. To develop the index, an interdisciplinary approach will be adopted, involving experts in the fields of sustainable building design, energy efficiency, water management, and environmental impact assessment. The index will encompass various dimensions of sustainability, including energy efficiency, water conservation, waste management, indoor environmental quality, and overall environmental impact. Key performance indicators will be established to quantify and evaluate the sustainability performance of DEWA's buildings. These indicators will be based on measurable data related to energy and water consumption, waste generation, and environmental emissions. The index will provide a systematic framework for tracking progress, identifying areas for improvement, and setting sustainability targets for DEWA's building portfolio. Furthermore, the study will address the importance of stakeholder engagement and create mechanisms for knowledge sharing and collaboration within DEWA. This will ensure that sustainability goals are integrated into the organization's culture and practices, fostering a sense of ownership and responsibility among employees. The outcomes of this study will be valuable for DEWA in optimizing energy and water consumption, reducing environmental impact, and enhancing the overall sustainability of its buildings. The index will also contribute to the broader sustainability goals of Dubai, aligning with the city's vision of becoming a global leader in sustainable development. Overall, the "Building Sustainability Index for Dubai Electricity and Water Authority" study presents a significant opportunity for DEWA to embrace sustainability as a core principle, driving positive change in the organization's operations and contributing to a more sustainable future for Dubai.
