  • HVAC systems (chillers, boilers, air handling units, pumps, and distribution systems)

  • Central plant and hydronic systems

  • Building automation and controls

• Review drawings, specifications, and equipment schedules to support system evaluations

• Evaluate technologies and equipment and assist with recommendations for specific applications

• Analyze utility billing data and system performance data to support baseline development

• Assist with engineering calculations related to equipment sizing, operating profiles, and system performance

• Investigate and document potential system improvement and infrastructure upgrade opportunities

• Support preparation of technical narratives, calculations, and backup documentation for feasibility studies and proposals

• Compile, organize, and qualitycheck engineering calculations and assumptions using Excelbased tools
