Energy Efficiency, Cost Analysis, and GHG Emissions Assessment for Healthcare Facilities: A Case Study#2

Title: Energy Efficiency, Cost Analysis, and GHG Emissions Assessment for Healthcare Facilities: A Case Study

Abstract: This case study presents an analysis conducted by Cambridge Engineering Consultants on the energy use, associated costs, and greenhouse gas (GHG) emissions for a healthcare facility. Study #02 focuses on sharing the Energy Use Index (EUI) and Energy Cost Index (ECI) for a hospital with a capacity of 100 beds. Additionally, the study calculates the annual GHG emissions, including emissions per bed. The results aim to provide insights into energy efficiency, cost optimization, and environmental sustainability in the healthcare sector.

1. Introduction: Cambridge Engineering Consultants has been actively involved in MEP design for healthcare projects since 2014. With a strong track record in designing MEP systems, conducting energy audits, and performing energy modeling, Cambridge has successfully contributed to over 15 healthcare projects. This case study, Study #02, examines the EUI, ECI, and GHG emissions for a hospital with a capacity of 100 beds, showcasing the potential for energy efficiency, cost reduction, and environmental impact mitigation in the healthcare sector.
2. Methodology: To evaluate the energy consumption, associated costs, and GHG emissions of the healthcare facility, Cambridge Engineering Consultants collected and analyzed data related to the hospital's operations. The methodology involved measuring the energy consumption and calculating the corresponding costs. Additionally, GHG emissions were estimated by considering the energy consumption and applying appropriate emission factors for the specific energy sources used.
3. Results: The analysis conducted by Cambridge Engineering Consultants revealed the following results for the hospital with a capacity of 100 beds:

• Energy Use Index (EUI): 380 kWh/m2
• Energy Cost Index (ECI): 68 SAR/m2

Further breakdown of energy consumption and costs per bed:

• Energy consumption per bed: 183 kWh/day
• Cost per bed: 33 SAR/day

Greenhouse Gas Emissions:

• Total annual CO2 emissions: 5000 tCO2
• CO2 emissions per bed (annually): 51 tCO2

1. Discussion: The presented EUI and ECI values provide valuable insights into the energy performance and associated costs of the hospital with a capacity of 100 beds. These benchmarks can serve as reference points for healthcare project stakeholders to evaluate and optimize energy efficiency in similar facilities. The breakdown of energy consumption and costs per bed offers a more granular perspective, enabling stakeholders to identify opportunities for energy-saving measures.

Furthermore, the assessment of GHG emissions underscores the importance of environmental sustainability in healthcare facilities. The calculated annual CO2 emissions and emissions per bed demonstrate the facility's carbon footprint. This information can help stakeholders understand the impact of their operations on climate change and prioritize initiatives for reducing GHG emissions through energy-efficient design, renewable energy integration, and sustainable practices.

1. Conclusion: Cambridge Engineering Consultants' expertise in MEP design, energy audits, and energy modeling has provided valuable insights into the energy performance, costs, and environmental impact of the hospital with a capacity of 100 beds. The EUI and ECI indices offer benchmarks for evaluating and improving energy efficiency, while the GHG emissions assessment highlights the need for sustainable practices in the healthcare sector.

By incorporating energy-efficient design strategies, implementing energy-saving measures, and adopting environmentally conscious practices, healthcare facilities can reduce their energy consumption, operational costs, and carbon footprint. Cambridge Engineering Consultants stands ready to provide comprehensive evaluations, tailored solutions, and guidance to healthcare project stakeholders aiming to achieve energy efficiency, cost optimization, and environmental sustainability.

Disclaimer: The presented EUI, ECI, and GHG emissions values are based on the specific healthcare facility analyzed in this case study. The results should be used as guidelines for benchmarking and evaluation purposes. Actual energy consumption, costs, and emissions
