The built environment, in particular, often fails to address the needs of nonhuman inhabitants, leading to habitat destruction, invasive species, pollution, and climate change. This thesis explores how thoughtful exterior lighting design can mitigate these environmental changes and promote biodiversity. Exploring the relationship between the built environment and nonhuman species, this paper shows the negative consequences of inadequate design and excessive electric lighting at night, including disrupted habitats, interruptions to vital ecosystem services, and contributions to biodiversity loss. By focusing on the potential of better exterior lighting design as a solution, this research highlights the importance of contextual and sensitive design approaches that consider the needs and behaviors of nonhuman inhabitants. Through site analysis and a review of existing literature, this thesis demonstrates the positive impact of well-planned exterior lighting design on various species, ecosystems, and the broader environment. The findings suggest that improvements in exterior lighting design can minimize the adverse effects of electric lighting on ecosystems. This thesis emphasizes a collaborative and interdisciplinary approach to addressing the needs of nonhuman inhabitants in the built environment, contributing to developing a more inclusive and responsible design practice. By outlining practical strategies and recommendations, this research encourages professionals and stakeholders to adopt more environmentally conscious and sensitive exterior lighting design approaches, ultimately fostering a harmonious coexistence between humans and the natural world.application/pdfstCC BYdark skiesecological designlight pollutionlighting designnocturnaluniversity of washingtonArchitectureLandscape architectureEnvironmental scienceArchitectureThesis
