Health Care


Pathian has a particular expertise and impressive record of energy cost reduction in health care facilities. On average, Pathian clients have reduced their average annual energy spend from 25 to 40 percent while maximizing occupant comfort and meeting all indoor air quality (IAQ) standards.

  • In January 2013, five of eighteen hospitals receiving ASHE E2C recognition applied Pathian energy management best practices. The top achiever, a Pathian client, recorded a 30% overall energy reduction.
  • Three of the top four 2013 ASHE E2C award winners reduced their energy consumption by over 25 percent.
  • With 2004 as a baseline year through 2010, a 1.25 million square-foot acute care hospital reported a total avoided energy cost of $5.5 million during that span, earning a 2010 Energy Star Award and ASHE E2C recognition.
  • From 2007 through 2012, a 900,000 square-foot acute care hospital reported a total avoided energy cost of $2.57 million and in 2012 received an ENERGY STAR® award and ASHE E2C recognition.

At Pathian, we understand the contemporary health care industry is changing. The Affordable Care Act (ACA), Centers for Medicare and Medicaid Services (CMS) compliance issues and a host of other dynamics are creating irresistible forces to reduce expenses — to do more with less.

Pathian Has Real Solutions

Pathian engineers have developed Pathian® Analysis®, patented and proprietary automated energy audits which precisely identify the causes and costs of inefficient HVAC mechanical systems energy consumption. These audits that historically cost hundreds of thousands of dollars are now affordable and 10 times more accurate, as they are not affected by outside weather conditions. More importantly, these data-driven and knowledge-based audits simultaneously generate corrective action solutions reflecting best-in-class system control logic and sequence methods. And since these audits are continuous, you will always have access to the most current and proven best practices. The result: sustainable and increasing energy costs savings.

It begins with a Component Level Benchmarking (CLB) Best Practice Survey to determine baseline energy usage expressed in dollars per square foot, including electric, natural gas and fuel oil consumption. We then:

  • Select HVAC components to monitor, turning each control point into a smart meter.
  • Import energy data from the hospital’s building management control system (BMCS) along with utility interval load data every 15 minutes through the Pathian Energy Management Portal. This information is assessed using the patented Pathian® Curves and Pathian Analysis technology tools.
  • Create a Pathian Performance Index™ (PPI™) for each energy point and control sequence to establish a comparative baseline.
  • Compare to best control sequence practices and peer hospitals to determine potential energy savings and the actions to achieve them.
  • Continue to monitor system performance to verify savings and continually identify further opportunities for additional energy savings.
