OpenBlue Central Utility Plant is an innovative software product which helps central energy facility managers and operators minimize operational costs, reduce energy consumption, reduce water consumption, and shrink carbon footprints.

The Project Engineer will develop detailed models that drive the optimization algorithms, assist with the commissioning and user training, and perform savings measurement and verification (M&V) analysis.

Essential Functions

  • Communicate with site engineers to analyze current central plant configuration, operation, and performance.
  • Gather, cleanse, and process data from various sources and utilize data analysis tools and techniques to organize the data for use in CPO analysis
  • Use energy modeling / simulation tools to estimate potential savings from implementing CPO and other energy conservation measures
  • Use problem solving skills to validate simulation results and troubleshoot simulations
  • Following integration to plant automation systems, lead the process of commissioning to ensure CPO algorithms are dispatching plant in an optimal fashion aligned with simulation models
  • Troubleshoot through plant automation systems to identify issues during commissioning.
  • Train and support plant managers’ and operators’ understanding of CPO software
  • Perform savings measurement and verification (M&V) analysis after CPO has been operational
  • Work on estimation and pre-sales support of different data driven products
  • What we look for : Required


  • Degree in Mechanical or Electromechanical Engineering
  • Knowledge of central plants (chilled water, hot water, steam, etc.)
  • Understanding of building cooling and heating loads, energy calculation methods, and energy performance of building mechanical / electrical systems
  • Understanding of HVAC equipment (e.g., hydronic systems, steam / condensate systems, chillers, boilers, cooling towers, pumps, heat exchangers, etc.)
  • Advanced business level in English (B2+) with strong written and verbal communication skills
