In conjunction with the New York State Research and Development Authority’s (NYSERDA) FlexTech Program, EMCOR Services Betlem performed an energy feasibility study for the Westfall Surgery Center and identified a number of possible efficiency improvements.  

Using data collected during multiple site visits and utility information provided by the client, we recommended six energy conservation measures that were projected to produce annual savings of $74,039 with a payback of less than eight years. As a part of the FlexTech program, the studies were cost-shared through NYSERDA rebates. 

Client Objectives

The client wanted to analyze facility and mechanical system performance, locate areas of energy waste, and identify opportunities for operational and efficiency improvements.


The feasibility study was conducted across the entirety of the 42,000-square-foot-facility, including in operating, treatment, and office spaces. 

Potential energy savings were calculated using a Trane Trace 700 energy model compared to weather normalized utility data.  We used real-time data logging to measure equipment performance and develop recommendations, which included:

  • Optimizing control scheduling and air distribution system 
  • Replacing chiller with high-efficiency equipment 
  • Installing variable frequency drives and variable air volume boxes to improve ventilation 
  • Decreasing unoccupied outside air damper position

After the audit was complete, we went on to install a new 85-ton tandem chiller and remote air-cooled condenser for the facility.
