Naga City is not unique to problems of flooding and housing shortage. It does, however, provide the opportunity for sustainable design and construction for future inspiration and all generations to benefit from. As part of the Technical University of Munich’s summer semester course, ‘Urban Water-Energy-Food Nexus Planning,’ our group has focused on creating a synergy nexus opportunity to address the major issues of flooding, housing, and energy consumption. We take inspiration from previous ‘Sponge city’ pilot projects, which combine green and gray infrastructure to create a ‘slow-release effect’ from flooding occurrences. It further serves to provide energy-saving opportunities by mitigating the ‘heat-island effect’ and saving energy on floodwater pumping. We also take inspiration from the ‘Pilot House’ project from the University of Naga City, which provides low-cost housing construction which is both energy efficient and flooding resistant. We discuss the stakeholders involved in the project, the potential business opportunities after construction, and assess the environmental effects after implementation as a way to mitigate climate change effects.
