Abstract：The nighttime outdoor lighting environment of healthcare buildings plays a crucial role in supporting patient recovery and overall physical and mental well-being.However,current lighting standards for medical facilities provide limited guidance,and practical design often lacks systematic attention to user experience and needs.This paper takes the Gansu Provincial Maternal and Child-Care Hospital project as a case study and adopts the Evidence-Based Design(EBD)approach to examine user-centered requirements throughout all stages of lighting design-from fixture selection and construction detailing to parameter settings and maintenance management.The study identifies four critical design dimensions essential for nighttime healthcare lighting environments:aesthetics appeal,wayfinding effectiveness,glare control,and appropriate brightness and color temperature.Through a subjective preference survey conducted at key lighting nodes,the study verified the effectiveness of several lighting design strategies,including emphasizing architectural fa çade coherence,adopting distant landscape lighting,and utilizing low-level roadway illumination.This research establishes a hospital outdoor lighting design process grounded in evidence-based design(EBD).This framework provides both practical reference and theoretical support for optimizing nighttime lighting environments in healthcare architectures and offers a reference for the development of relevant design standards.
