Celebrate the Other Side of Day with the Nighttime Design Initiative We are an international team generating “Nighttime Design”, an interdisciplinary, socially aware approach to the issues of cities after dark, conducting research, education and strategic planning. The methodology is site specific and localized — applicable to communities everywhere — cognizant of geography, culture and climate. The Nighttime Design project has innovated a multifaceted design process to revitalize cities, which includes pilot-based research to envision a practical and sustainable strategy for urban lighting. This strategy considers the holistic possibilities of the night hours, and the citizens that inhabit them. Urban lighting can transform the way a city operates at night. Ultimately, the goal of the NTD project is to increase safety and security, stimulate economic growth, improve public health, and increase social interactions into the night hours for cities around the world. The Nighttime Design process has already proven successful in numerous cities with visible impacts. We hope to see more citizens, government, and urban professionals utilize the Nighttime Design methods to enliven and protect the future of our cities.
