Transforming Healthcare Facilities: Sutter Health’s Eden Medical Center’s Success Story in Sustainable Energy Efficiency

In an era where environmental sustainability is paramount, healthcare facilities across the globe are embracing innovative solutions to reduce their carbon footprint while simultaneously achieving significant cost savings. Sutter Health’s Eden Medical Center (EMC) stands out as a shining example of a healthcare institution that has successfully executed a comprehensive turnkey energy efficiency project, resulting in substantial financial savings and a substantial reduction in its environmental impact.

EMC’s journey toward energy efficiency was characterized by strong engagement from facility staff, diligent execution, and a commitment to long-term sustainability. The hospital’s partnership with Bernhard, a leading energy solutions provider, yielded remarkable results. The results of this energy project highlight the comprehensive strategies employed, the measurable outcomes achieved, and the broader implications for the healthcare industry.

The Scope of EMC’s Energy Efficiency Project

EMC’s energy efficiency project was no small feat. It encompassed a range of measures, each contributing to the overall goal of reducing energy consumption and greenhouse gas emissions while optimizing operational efficiency. The project’s primary objectives included:

  1. Upgrading to Energy-Efficient LED Lighting: A facility-wide LED lighting upgrade played a pivotal role in reducing electricity consumption.
  2. Enhancing Central Chilled Water Plant Operations: Operational improvements to the central chilled water plant significantly contributed to electric savings and overall system efficiency.
  3. Implementing Temperature Reset Strategies: Innovative strategies at the air handling units minimized reheat in spaces and reduced unnecessary load on the chiller plant, resulting in natural gas savings.
  4. Terminal Box Temperature Range Standardization: Terminal boxes were programmed to maintain zone temperatures within standardized ranges, saving cooling and reheat energy and promoting uniformity in temperature control.
  5. Optimizing Pump VFDs: Savings were generated from power reductions achieved through variable frequency drives on pumps.
  6. Chilled Water dP Reset/Adjustments: Chilled water secondary pressure controls reset based on AHU’s valve position/demand, optimizing chiller plant equipment staging for efficient operation.
  7. Air Handler Optimization: AHUs operated with supply air temperature resets based on terminal unit demand, reducing reheat and chiller plant load.

The Tangible Benefits: Measured Energy Savings

The success of EMC’s energy efficiency project is not just anecdotal; it is backed by concrete data. The project resulted in impressive energy savings, demonstrating its impact at both the system level and the utility bill level:

  • Electric consumption decreased by 14%.
  • Natural gas consumption decreased by 24%.

A thorough verification process, including regression curve analysis, weather normalization, and monitoring-based commissioning (MBCx) using SkySpark and Bernhard Analytics, confirmed these savings and is providing a deeper level of information to the building operators, improving their productivity in maintaining patient and staff comfort levels. The annual savings is $517,890, with a potential for even greater savings as utility rates escalate.

Sustainability Beyond Savings

EMC’s commitment to sustainability extends beyond the immediate financial benefits. Their approach to energy efficiency includes ongoing monitoring and evaluation through the MBCx program. Engineers from Bernhard collaborate with Sutter Health’s Eden Medical Center staff, ensuring the achieved savings persist and identifying additional opportunities for improvement.

Conclusion

Sutter Health’s Eden Medical Center’s energy efficiency journey serves as a compelling case study for the healthcare industry. Their multifaceted approach, measurement and verification, and ongoing commitment to sustainability showcase what is possible when healthcare facilities prioritize both environmental responsibility and fiscal prudence.

As healthcare institutions worldwide seek ways to reduce their carbon footprint and operational costs, EMC’s story provides a roadmap for success. By embracing energy efficiency projects with a holistic and long-term perspective, hospitals can not only save substantial sums but also contribute significantly to a more sustainable future for all.

EMC’s journey reminds us that energy efficiency is not just about reducing expenses; it’s about building a healthier, more sustainable world for generations to come.

Bernhard and Maury Regional Medical Center Announce 25-year Partnership Kickstarting $115 Million Expansion Project

________________

Bernhard and Maury Regional Medical Center have agreed to an innovative 25-year Energy-as-a-Service partnership to act as the catalyst for Maury’s groundbreaking $115-million facility improvement plan to enhance patient care and experience.

“Each day our hospital honors an everlasting promise to our community to provide the absolute best in state-of-the-art health care,” said Charlie Brinkley, Maury Regional Health CAO. “Bernhard’s unmatched history in energy solutions makes them the perfect partner as we upgrade and expand our facility infrastructure to provide advanced, comprehensive care close to home for the families of Southern Middle Tennessee.”

Throughout the length of the partnership, Bernhard will manage Maury’s complete energy portfolio with facilities spanning over 600,000 square feet. Bernhard will implement $17 million of infrastructure improvements, including technology modernization and energy optimization, resulting in 39% guaranteed energy savings for the hospital. Bernhard teams will upgrade and replace energy assets throughout the facility including air handlers, controls, and ventilation to increase reliability, maximize performance, and reduce operating costs.

Bernhard’s EaaS structure provides Maury with seed capital to begin its first major construction project in 20 years to support growing service lines, offer additional services, and expand facilities to meet the changing needs of its community.

As the first EaaS project in the Tennessee healthcare sector, the Maury Regional-Bernhard partnership marks a historical moment. Bernhard joined the Tennessee Hospital Association’s THA Center for Innovative Solutions (TCIS) in 2019 as their chosen Energy-as-a-Service provider for its member hospitals.

“At our core, TCIS is all about relationships,” said Anne Brandner, Senior Vice President at TCIS. “Being able to connect Maury Regional Medical Center with an invaluable strategic partner like Bernhard and the most sophisticated energy solutions in the market empowers Maury Regional Medical Center to achieve their core mission of delivering clinical excellence and compassionate care.”

Bernhard’s turnkey solutions provide the hospital with the benefits of efficient and reliable energy without the need to directly manage energy production and use. This transfer of operations and maintenance allows Maury to shift focus and resources wholly to its mission-critical healthcare services.

“Bernhard was built on empowering our clients through innovative energy solutions,” said Jimmy Veteto, Vice President of Business Development at Bernhard. “We are proud to partner with Maury Regional Medical Center to provide Energy-as-a-Service solutions that promote its core mission and allow for the acceleration of an expansive renovation plan bettering patient care in Tennessee for years to come.”
