This session explores the design of a zero-net-energy public preschool in San Bernardino, emphasizing climate-responsive architecture, ecological preservation, and child-centered spatial strategies. Attendees will learn how the project integrates passive design to mitigate harsh winds and optimize natural ventilation, while preserving mature trees to enhance outdoor learning environments. The course highlights the use of low-embodied-carbon materials and interdisciplinary collaboration to reduce the building’s environmental impact. Additionally, it examines how scaled, sensory-rich design elements support early childhood development through exploration, autonomy, and refuge. Participants will gain insight into balancing sustainability, universal access, and educational program needs to create healthy, safe, and inspiring spaces for the youngest learners. This integrative approach offers replicable strategies for architects designing high-performance, resilient educational facilities.
