Good Samaritan Hospital
375 Dixmyth Avenue
Cincinnati, OH 45220
Map It!


As the oldest and largest private teaching and specialty health care facility in Greater Cincinnati, TriHealth?s Good Samaritan Hospital is among the best hospitals in the region, providing a range of quality services to patients in Ohio, Indiana, and Kentucky.


The hospital is a member of Catholic Health Initiatives and is the pre-eminent Catholic hospital in the community, proudly serving all sectors of the population. With many highly respected programs and services, the hospital is regularly recognized by Thomson Reuters, U.S. News & World Report and other prestigious publications and research organizations as one of the top hospitals in Greater Cincinnati. Most importantly, the community trusts and relies upon the hospital?s services every day to care for loved ones from birth into the many stages of life.


The Sisters of Charity of Cincinnati opened Good Samaritan more than 150 years ago. Since then, the organization has grown from a small facility with 21 beds to one of the largest hospitals in the city, with more than 650 beds and encompassing more than a city block. To further meet the needs of the growing community, the hospital recently completed an extensive modernization and expansion project that added a new 10-story patient care tower and renovated numerous existing hospital spaces.


Good Samaritan Hospital is living proof that you do not need to spend millions of dollars to have an effective energy management program. This story is about taking existing mechanical systems, whatever they may be, and making them operate in the most energy efficient manner possible. Careful planning and a cultural change in your energy consumption habits are what are most important. Here?s how it was done:


Setting Energy Reduction Goals

In 2007, the Good Samaritan Hospital began work with Pathian Incorporated to develop a sustainable energy reduction program at our hospital. The primary goals of this partnership were:

-- Create a five-year budget neutral energy reduction plan.  In other words, the energy saving must pay for all energy reduction improvements each year.

-- Engineer a solution to the hospital?s building pressurization problem?s and integrate it into the five-year energy reduction plan budget.

-- Develop a sustainable energy reduction program.

-- Change the culture from an Energy System Users to Energy System Managers mentality.


Developing the Five-Year Energy Improvement Plan

-- Pathian Engineers performed a rigorous inspection of all primary air handler HVAC control system.  The inspection goals were to identify how our existing control systems functioned, verify calibration of peripheral devices, and understand to overall condition of our mechanical systems in general. The hospital used Pathian? Analysis (patent pending) load-based benchmarking profiles to understand energy consumption habits and develop comparative energy consumption standards at all operating loads. 

-- Pathian created a Syrx? Energy Plan for the facility.  This in-depth plan outlined all existing issues. 


The focus of the engineering was to create global HVAC control strategies that allowed our equipment to function as a single machine to control building pressure and react to changes in building load.


Putting the Plan in Action

-- Pathian hired an HVAC control contractor and began implementing the hospital?s Syrx? Energy Plan.  The plan was designed to address ?low-hanging fruit? tasks first and move on to the next highest rate of return task.

-- The Syrx? Energy Plan detailed how to control the hospital?s building pressure control problems.  Pathian used what they call Pathian Optimal Building Pressure Control (POBPC) to control building pressure.  It is an elevation-based building pressure control method developed by Pathian.  It makes all mechanical systems work together to control building pressure to +/- 0.001 IN WC in the main hospital lobby.


Upholding Sustainability Values

-- The most important aspect of the hospital?s sustainability is its ability to measure how the hospital consume energy.  Using Pathian?s load based energy benchmarking method, management understands in precise detail how the mechanical systems consume energy at all operating loads.

-- Staff training has helped the hospital community understand how it consumes energy and helped identify problems.



-- Since 2007, the hospital has improved energy consumption by 24.6 percent by making the existing mechanical system work more efficiently.

-- Management was able to retrofit the entire HVAC control system to new, high efficiency control methods while maintaining budget neutrality in the process.

-- For every dollar the hospital spent on an energy consultant, it has received four dollars as a return on investment.
