Omar Sweeney is an astute Engineering Professional with three decades of experience, specializing in Civil, Construction Engineering and Project Management. Throughout his professional career, he has successfully led the charge for several major Government-related and social intervention programs and infrastructural projects. He holds a Master of Engineering from the University of Florida. He has completed postgraduate executive training programs at the London School of Economics and the University of Oxford.
Vani Ruchika Pabba holds a Master of Science in Computer Science from the Herbert Wertheim College of Engineering at the University of Florida, where she served as a Graduate Research Assistant. Her research focuses on artificial intelligence in education, including natural language processing for automated grading and feedback generation, multi-modal learning (integrating vision and language models), and generative AI. Her broader interests include sustainable computing, IoT, and the development of smart cities and connected environments. Prior to her graduate studies, she accumulated three years of professional experience as a Software Engineer in India, specializing in software design and development for enterprise applications. She is committed to advancing educational technology and addressing real-world challenges through innovative computing solutions.
For more than 40 years, Dr. Najafi has worked in government, industry, and education. He earned a BSCE 1963 from the American College of Engineering, University of Kabul, Afghanistan. In 1966, Dr. Najafi earned a Fulbright scholarship and did his B.S., MS, and Ph.D. degree in Civil Engineering at Virginia Polytechnic Institute and State University, Blacksburg, Virginia; his experience in industry and government includes work as a Highway Engineer, Construction Engineer, Structural, Mechanical, and Consultant Engineer. Dr. Najafi taught at Villanova University, Pennsylvania, and was a visiting professor at George Mason University and a professor at the University of Florida, Department of Civil and Coastal Engineering. He has received numerous awards, such as Fulbright scholarship, teaching awards, best paper awards, community service awards, and admission as an Eminent Engineer into Tau Beta Pi. The Florida Legislature adopted his research on passive radon-resistant new residential building construction in the HB1647 building code of Florida. Najafi is a member of numerous professional societies and has served on many committees and programs; and continuously attends and presents refereed papers at international, national, and local professional meetings and conferences. Lastly, Najafi attends courses, seminars, and workshops and has developed courses, videos, and software packages during his career. Najafi has more than 300 refereed articles. His areas of specialization include transportation planning and management, legal aspects, construction contract administration, public works, and Renewable Energy.
The research aims to examine the ability of countries to develop sustainable cities and pursue a target of net-zero greenhouse emissions through renewable energy to address today's city problems and offer affordable sustainable solutions. Over a hundred countries agreed at the Lima Climate Summit in December 2014 to pursue a target of net-zero greenhouse emissions through renewable energy by 2050, and many cities have made pledges to switch to 100% renewable forms of energy. Urban sprawl produces excessive traffic and smog. The lack of effective zoning policies eliminates the optimal placement of infrastructure activities in sustainable zones. Developing nations, for example small island developing states (SIDS), do not have the resources to implement many aspects of a sustainable city. Some problems created by the lack of a sustainable city include poverty, jobs, cost of living, sustainable growth, land conservation, citizens and government relationships, private sector investment, socio-economic challenges, technological advancement, and resilience to climate change. From the literature search, solar, wind, wave, geothermal, biomass, and technology applications lead toward a sustainable city. The research also shows sustainable cities should use multiple energy sources via an integrated resource plan that would employ solar power on calm days and wind power on cloudy days to meet their inhabitants' energy demands. Masdar City in the United Arab Emirates is examined as a case study; Masdar uses a pre-designed sustainable city approach, such as renewable energy and green technology, to get to the ideal of net zero and a reduced carbon footprint. The research also looked at 2 other cases in Tianjin, China, and Osceola County, Florida, USA. The other cases prove that a hybrid approach using the best elements based on country-specific advantages is articulated. For example, the Middle East should use photovoltaic systems due to the abundance of solar radiation. Northern Europe could use wind and geothermal to accommodate the lack of sunlight during winter. A sustainable city plan can design the city so that workplaces, shopping plazas, and entertainment centers are within walking or biking distance of residential areas, along with mass transit powered by fuel cells or electric vehicles. Also, planners should design buildings to use sunlight, passive cooling, solar water heating, and green roofs to reduce the urban heat island effect. The research concludes that Incremental, sustainable improvement in existing cities and implementing affordable practices as urban areas expand will be more achievable than building new, expensive cities from scratch.
