The building and construction sectors account for over one-third of global final energy consumption and nearly 40% of total direct and indirect CO2 emissions. At the same time, hospital buildings are often among the least energy-efficient. Enhancing the energy performance of existing hospital buildings through retrofitting measures presents a significant opportunity for cost and energy savings. However, hospitals have unique challenges, such as continuous occupancy, heavy medical equipment, and strict safety regulations. Additionally, the lack of financial incentives and supportive policies are among the biggest barriers to retrofitting hospital facilities. This paper proposes an energy management methodology for selecting the best retrofitting measures for hospital buildings. Moreover, the study seeks to define a priority ranking for the energy efficiency measures selected in an energy retrofit project, distinguishing between primary and supplementary actions. The methodology includes a generic process flow diagram, a systematic flowchart to facilitate decision-making, and two tables outlining primary and supplementary retrofitting measures.
