Retrocommissioning

Restoring and Enhancing Building Performance

Uncover hidden inefficiencies, unlock energy savings, and improve long-term building resilience with retrocommissioning (RCx).

Buildings are dynamic environments—over time, systems drift from their original performance due to aging equipment, operational changes, and evolving occupant needs. We apply commissioning principles to existing buildings to restore, optimize, and often exceed their original design intent. Our structured approach ensures that mechanical, electrical, and plumbing systems operate reliably, efficiently, and in alignment with modern performance standards.

A Data-Driven Approach

Guided by industry best practices and executed by professional engineers, our process follows four key steps:

  • Planning

    Working together to establish project goals, scope, and key performance benchmarks to bring buildings back to their intended efficiency.

  • Investigation

    Conducting a comprehensive system analysis to diagnose inefficiencies, equipment failures, or operational inconsistencies.

  • Implementation

    Applying corrective measures, from control system optimization to equipment repairs and energy efficiency upgrades.

  • Turnover and Persistence

    Ensuring building operators are trained to sustain improvements and embedding long-term performance tracking.

The Value of Retrocommissioning

While energy cost reduction is a major benefit of RCx, the value extends far beyond efficiency gains. Retrocommissioning is a strategic tune-up, delivering:

  • Lower Operational Costs – Identifies and corrects inefficiencies that drive up energy and maintenance expenses.
  • Enhanced Occupant Comfort – Ensures temperature control, ventilation, and lighting systems operate as intended for an optimal indoor environment.
  • Improved Indoor Environmental Quality (IEQ) – Reduces unnecessary energy use while enhancing air quality and system reliability.
  • Extended Equipment Lifespan – Reduces wear and tear on building systems through optimized operation and preventive maintenance strategies.
  • Safety and Compliance for Critical Environments – Verifies and optimizes pressure relationships, air change rates, and ventilation performance to meet stringent healthcare, laboratory, and cleanroom standards.

Our RCx services are tailored to maximize efficiency and system reliability while ensuring compliance with evolving energy codes and industry standards. Whether your facility requires targeted system improvements or a comprehensive building-wide commissioning effort, we can help you restore your building and elevate your operations.
