Building Comissioning – SustainErgy

Commissioning Services

SustainErgy provides building commissioning services to help ensure building systems are designed, installed, and operating as intended, supporting improved energy performance, occupant comfort, and long-term operational reliability.

Even well-designed buildings often underperform due to control issues, system interactions, or changes that occur over time.

Common challenges include:

Operational Misalignment

Building systems not operating as originally intended

System Integration Gaps

Poor integration between mechanical, electrical, and control systems

Comfort & Efficiency Loss

Inconsistent comfort conditions and unnecessary energy use

Knowledge & Documentation Gaps

Limited documentation or staff knowledge to support effective operation

Performance Drift

Performance degradation following renovations, retrofits, or occupancy changes

The Commissioning Solution

Commissioning addresses these challenges by systematically verifying system operation and optimizing performance throughout the building lifecycle.

Building condition assessments address these challenges by providing a structured,
building-level overview of observed conditions to support long-term planning.

Lifecycle-Aligned Commissioning

SustainErgy delivers commissioning as a structured, adaptable process that aligns with the building’s lifecycle stage, operational needs, and owner objectives.

We define commissioning objectives, system boundaries, and documentation requirements based on whether the project involves new construction or an existing facility.

Building systems and controls are reviewed through documentation analysis, site observations, and functional testing to understand how systems are operating in practice.

Key systems and sequences are tested to verify performance, identify deficiencies, and confirm alignment with design intent or operational requirements.

Findings are translated into practical corrective actions, with a focus on low-cost and no-cost operational improvements where feasible.

Results are documented, and building staff are supported through training and guidance to help sustain performance improvements over time.

Service Scope & Outputs

Commissioning services are tailored to the building type, lifecycle stage, and operational context, and may include:
