| | Article written by hospital director, reporting the experience in the organization. It presents a graph with results obtained and spreadsheets to calculate savings obtained used with employees. | Interventions to reduce energy consumption in existing buildings. Gradual investments and reinvestment of savings obtained. | It only mentions the management of improvement opportunities in existing buildings, with monitoring of results. | Restricted to recover the initial investment in the operation phase. | Raising workers’ awareness of energy savings, data usage, customized calculation tools. Potentially benefited community through the reproduction of learning. | Technological update of the boiler, air conditioning and lighting systems. Window replacement as a passive strategy. In old buildings, adoption of more efficient solutions according to the need for maintenance and adaptations. |
| | Article. Interview with building systems specialist. Provides an approach to improve the organization’s financial and operational performance. | Building systems design, with emphasis on operating costs. | Long-term evaluation should guide the project. This should be linked to the facilities master plan and integrated with strategic planning. | The concept should guide the project, with the evaluation guiding the decisions. It presents the information that 75% of the cost is in the operation phase. | - | Long-term plans, avoiding fragmented and reactive maintenance; greater control over costs and risks in contracts with third-party providers; results-based agreements. |
| | Article. Highlights the impact of HU energy consumption. It uses quantitative data and comparison with other types of buildings. | Possibility of reducing energy consumption by joining a government program. | - | - | - | Reduction of energy consumption; greater systems efficiency; adherence to the government’s Energy Star program. |
| | Article. Reports hospital adherence to an energy conservation program. It presents consumption reduction data and a simplified methodology for calculating the internal rate of return on investments. | Gradual upgrade of systems. Measures in line with the US Environmental Protection Agency’s Energy Star Building program. Saving financial resources and reducing environmental impacts. | Intervention planning in five phases, with gradual disbursements, with a return on investments. Focus on decision makers based on the attractiveness of return estimates. | Restricted to recover the initial investment in the operation phase. Provides estimates of internal rates of return and risk factor. | - | Digital climate control; more efficient building systems; lighting as an initial target. Sequence of interventions initiated by the least costly, aimed at reducing the thermal load, finally updating air conditioning equipment. |
| | Article. Case report with company energy conservation strategy that controlled more than 170 hospitals of the USA. Displays consumption indicators per unit of floor area. | Reduced energy consumption for lower operating costs. Adoption of innovative solutions, some of which are not yet viable or have operational problems. | Internal team of professionals to identify needs and project guidance activities. Control and evaluation of construction quality, performed by third parties. | The evaluation of alternatives by the internal team and representatives of the architecture, engineering and construction companies occurs based on the life-cycle cost. | Highlights the support of management and workers to the team responsible for maintenance as a key point. | More efficient lighting, considering the work surfaces and coating materials of the environments; thermal insulation of the envelope; solar energy; harnessing the heat from incinerators. |
| | Article. Reports characteristics and design strategies of a hospital completed in 1975. | Project methodology based on life-cycle cost assessment and operational flexibility. | Environment layout, possibility of modifications and resizing, according to flow criteria and specifications based on the life-cycle cost assessment. | Explicit concept in the text. Evaluation to specify materials, systems and components, aiming at lower operational cost, despite the higher initial cost reported. | Comfort and convenience for the patient; objective location criteria as a facilitator of work processes; good relationship with the community. | Streamlined construction with panels and shafts for installations independent of the structure; durable materials with low maintenance cost; greater efficiency of the heating system. |
