In the fight against climate change, an unexpected frontline has begun to form. Healthcare facilities, designed to heal and protect, ironically contribute significantly to global carbon emissions. The healthcare sector is responsible for 4.4% of global net emissions, equivalent to the annual greenhouse gas emissions of 514 coal-fired power plants[1]. Healthcare facilities face a unique challenge: how can we maintain the highest standards of patient care while dramatically reducing the environmental impact of healthcare facilities?
The answer lies in taking proactive action by strategically retrofitting our current healthcare infrastructure. This approach offers a compelling solution that addresses both immediate healthcare needs and long-term sustainability goals.
The urgency of this task cannot be overstated. Hospitals operate 24/7, consuming vast amounts of energy to power life-saving equipment, maintain sterile environments, and provide comfort for patients and staff. This constant demand and mission-critical nature of healthcare facilities make them prime candidates for energy-efficient upgrades. By implementing a calculated retrofit and redesign, hospitals can significantly reduce their energy consumption without compromising on quality care.
Integrating renewable energy sources into existing healthcare facilities presents another compelling argument for retrofits. While the constant energy demands of hospitals make a complete transition to renewables challenging, hybrid systems offer a viable solution. Consider the Wexham Park Hospital project, which embarked on an ambitious energy project. Through a £7.5 million energy infrastructure upgrade, including the installation of a 1.5 MWe Combined Heat and Power plant, the hospital achieved remarkable results. The new system now displaces 90% of grid electricity and provides 75% of the hospital’s heat, reducing annual carbon emissions by 1,621 tonnes and saving £475,000 in energy costs annually. Importantly, these savings have exceeded initial projections by 50%, demonstrating that well-executed retrofits can surpass expectations in both environmental and financial benefits while maintaining uninterrupted patient care.
The financial case for healthcare retrofits is equally strong. The EPA estimates that as much as 30% of the energy consumed in hospitals and other commercial buildings is used unnecessarily[1]. Given that energy is approximately 50% of a facility manager’s budget[2] (i.e., utilities and building management), hospitals can reduce their operating costs by using energy more efficiently. While initial costs can be significant, the long-term savings in energy and operational costs often result in a relatively short payback period. Moreover, as carbon pricing and emissions regulations become more stringent, hospitals that have already invested in sustainability will be better positioned financially and operationally.
Financing options for these retrofits are increasingly available. Green bonds, energy savings performance contracts (ESPCs), and government incentives can help offset initial costs. Through an ESPC, the Medical University of South Carolina (MUSC) was able to increase the energy infrastructure capacity for its growing campus while improving reliability and control, improve air quality and significantly cut energy and operational costs.
As weather anomalies intensify, hospitals must be prepared to withstand extreme weather events and continue operating under challenging conditions. Retrofits that incorporate resilience measures, such as flood protection and backup power systems using clean energy sources like solar, Battery Energy Storage Systems (BESS), or microgrid systems, ensure that hospitals can continue to serve their communities even in the face of climate-related disasters.
The path to sustainable healthcare facilities through retrofitting is not without challenges. Upgrading systems while maintaining uninterrupted patient care requires meticulous planning and execution. However, the potential benefits – reduced carbon emissions, improved patient outcomes, financial savings, and enhanced resilience – make this a critical investment for the future of healthcare.
As we confront the global climate crisis, the healthcare sector has a unique opportunity to lead by example with partners who can guide them through this process. By retrofitting our hospitals for sustainability, we can create healing environments that not only care for patients but also for the planet. The time to act is now – our health, and the health of our planet, depends on it.
This free resource provides a tangible roadmap for organizations looking to reduce their carbon footprint and achieve net zero emissions. The built environment is responsible for roughly 40% of energy-related carbon emissions. This resource offers a holistic approach to cutting consumption, costs, and carbon and practical solutions for facility owners and operators.
