Optimizing Employee Awareness Strategies for Energy Efficiency in Healthcare: A Comparative Study Using Picture Fuzzy CIMAS and SIWEC

Background: Hospitals are in the category of buildings that consume the most energy. Considering these characteristics of hospitals, energy efficiency becomes important. For this reason, healthcare professionals are seen as an important factor in ensuring energy efficiency in hospitals. The purpose of this study is to identify the priority strategies required to increase the awareness level of hospital employees on energy efficiency. Methods: In line with the aim of the study, healthcare worker factors affecting efficiency in hospitals are determined based on the literature. After that, the importance weights of these criteria are calculated using the picture fuzzy criteria importance assessment (CIMAS) technique. In addition, a comparative analysis is carried out with the picture fuzzy simple weight calculation (SIWEC) approach. Results: The main contribution of the study is to determine the optimum employee strategies to provide energy efficiency. This issue has a guiding feature for hospital managers and policymakers. It is concluded that the most important criterion for these employees is reward programs (w=0.209). The second most important factor is found as creating energy-saving awareness (w=0.185). Conclusions: To achieve this goal, it would be beneficial to apply motivating factors to employees. In addition, increasing the awareness level of employees makes a significant contribution.
