DECARBONISATION


Northeast Georgia Medical Center Braselton. PV systems, on the other hand,


generate electricity that can power various hospital systems, including lighting, HVAC, and medical equipment. Advances in PV technology have improved the efficiency and affordability of these systems, making them a viable option for hospitals looking to reduce their carbon footprint and operating cost. PV systems can be installed on rooftops, parking structures, and other available spaces, providing a renewable source of electricity with minimal environmental impact.


Integrating renewable energy with hospital systems To maximise the benefits of renewable energy, hospitals can integrate solar energy systems with other electric systems, such as heat pumps, heat recovery chillers, and thermal energy storage. This integrated approach can enhance energy efficiency, reduce emissions, and improve the overall sustainability of hospital operations. For example, PV systems can provide electricity to power heat pumps and heat recovery chillers, reducing the need for fossil fuels and lowering carbon emissions. Solar thermal collectors can provide a renewable source of heat for domestic hot water and space heating, further reducing reliance on fossil fuels. In addition to solar energy, hospitals


can explore other renewable energy sources, such as wind and geothermal energy, depending on the suitability of the site.

Challenges and considerations While the transition to all-electric hospitals offers significant benefits, it also presents challenges that must be addressed, including a backup power source when utility power fails and the high initial cost of design and construction. While these systems can provide long-term savings through reduced energy consumption and maintenance costs, the initial investment can be substantial. Creative financing options, including


grants, loans, and incentives from government programs and utility companies, can help overcome this challenge. Hospitals may prioritise energy efficiency measures to reduce overall energy demand, making it easier and more cost-effective to transition to all- electric systems.


Another challenge is ensuring the


reliability and resilience of electric and renewable energy systems. Hospitals require continuous and reliable power to ensure patient safety and care. On-site energy storage options include batteries and thermal energy storage, or traditional diesel-engine generators to provide backup power and balance energy loads. These systems can store excess energy generated from renewable sources and release it during periods of high demand or power outages. Finally, hospitals must consider the impact of electric and renewable energy systems on their existing infrastructure and operations. Implementing these systems may require modifications to


building systems, electrical infrastructure, and operational processes. Hospitals can work with engineers, architects, and other stakeholders to develop comprehensive plans that minimise disruption and ensure a smooth transition to all-electric systems.


Conclusion The transition to all-electric hospitals is not only feasible but also essential for achieving decarbonisation goals and addressing the urgent public health crisis posed by climate change. By replacing traditional fossil-fuel-based systems with electric alternatives such as heat pumps, heat recovery chillers, and solar energy, hospitals can significantly reduce their carbon footprint and improve energy efficiency. This transition requires a comprehensive approach, integrating various systems and technologies to recover and reuse heat, optimise energy use, and reduce greenhouse gas emissions. Healthcare organisations, policymakers,


and industry stakeholders must collaborate to drive this transition, supported by goals and mandates for decarbonisation. By pioneering the future of sustainable healthcare, hospitals can fulfil their mission of ‘doing no harm’ not only to patients but also to the environment, ensuring a healthier and more resilient future for all. The journey towards all-electric hospitals represents a critical step in the broader effort to combat climate change and protect public health, setting a powerful example for other sectors to follow.
