A Systematic Review of Energy Efficiency and Lighting Control Interactions.

ObjectivesThis study investigates the interplay between energy efficiency, lighting control, and window design in hospital settings, emphasizing their collective impact on sustainable healthcare operations.BackgroundDespite growing attention to energy conservation in healthcare, limited research comprehensively addresses how lighting strategies, window designs, glazing solutions, and occupant behavior interact to optimize energy use while enhancing patient environments.MethodsA systematic review of 43 rigorously selected studies was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, analyzing research across architecture, engineering, environmental science, and healthcare disciplines to explore these relationships.ResultsThe findings highlight that adaptive lighting, high-performance glazing, and optimized window design play a crucial role in enhancing energy efficiency, lowering operational costs, and improving patient comfort.ConclusionThis study provides actionable insights for healthcare professionals, facility managers, and policymakers to promote sustainable hospital design by integrating energy-efficient strategies.
