| | Study. Interviews with hospital project directors and leaders regarding a set of values present in HU projects, previously extracted from the literature. | How hospital properties can add value to the healthcare organization, which values are prioritized in practice and why. | Survey of guiding values in decision making and how they are physically reflected in the project. | The prioritized values proved to be different in the different phases of the life cycle, that is, between the phases of initiation, design and use of the building. | Support for the patient’s needs and well-being, facilitated health processes, productivity and team satisfaction, support for the multidisciplinary organizational culture and work processes focused on the patient. | Based on the interviews, it presents an impact matrix with design decisions for saving water and energy; alternative energy sources; greater efficiency in air conditioning and material specification. |
| | Article. Describes the operation and benefits of LED lighting technology. | Energy efficiency, light quality, installation and maintenance flexibility and infection control. | - | Restricted to recover the initial investment in the operation phase. | Patient satisfaction and well-being, greater efficiency in tasks | Replacement of other LED lighting systems, combined with drive controls and sensors. |
| | Article. Interview CEO of a hospital. Description of an intervention case and interviewee’s reports. | Energy efficiency, with reduced consumption and local generation with renewable sources. | Restricted to investment in the technical engineering team and evaluation of alternatives. | Restricted to recover the initial investment in the operation phase. | Excellence in patient care. Hospital’s role focused on community education and well-being. | More efficient design and construction; energy conservation using renewable sources and selling the surplus produced. |
| | Article. Interviews experts and managers, citing studies and programs from third parties. | Sustainability. Measurement of the quality of cost decisions. | As a requirement to achieve aggressive sustainable goals, aimed at more efficient systems and the adoption of passive strategies. | Restricted to recover the initial investment in the operation phase. | Portrait of the hospital’s mission, focused on the well-being of the patient, workers and community. | Passive design strategies in the building envelope, reducing the need for artificial lighting and air conditioning; alternative energy sources, with the sale of the surplus. |
| | Article. Describes the operation and benefits of LED lighting technology. | Energy efficiency; better color reproduction; adjustment to the circadian cycle; less toxicity; installation and maintenance flexibility. | - | Restricted to recover the initial investment in the operation phase. | Patient well-being with the adaptation of lighting throughout the day and by environments. | Replacement of other LED lighting systems, combined with drive controls and sensors. |
| | Study. Assessment of the feasibility of energy auditing as a management strategy. Methodology: data collection; device location, inspection and analysis; quantification of total investment and payback period; and final report. | Audits in Spanish primary Healthcare Unit between 2005 and 2010, identifying concrete measures for intervention in order to reduce energy consumption. | It does not address directly. The description of intervention measures is restricted. | Restricted to recover the initial investment in the operation phase. | Internal management based on team awareness is seen as a zero-cost measure with the potential for savings. | Review of contractual conditions with the concessionaire; installation of power capacitors; updating of hot water, lighting, and air conditioning systems; adequacy of the envelope; adoption of renewable energies; and internal management. |
