Identifying Enhancements for Efficient Performance in Pre-existing Structures: A LEED Green Associate Perspective in USGBC

Retrocommissioning is a vital process for maintaining and enhancing the sustainability of our built environment. Unlike energy modeling, it is a systematic approach to evaluating and optimizing existing building systems, with the primary goal of improving performance and efficiency.

This process is not limited to a mere examination of the building's mechanical, electrical, plumbing, automation, and control systems. It also includes making necessary repairs or improvements to ensure that these systems function optimally. The retrocommissioning team, consisting of specialists in building performance, energy management, and systems engineering, is responsible for this comprehensive evaluation and optimization.

The retrocommissioning team's work is essential for ensuring that building staff are trained in the operation and maintenance of systems. This training is crucial for maintaining the efficiency of the building and improving occupant comfort and productivity.

Retrocommissioning contributes to the Existing Buildings: Operations & Maintenance (EBOM) rating system in the LEED certification. This means that buildings that undergo retrocommissioning can earn points towards their LEED certification, making retrocommissioning essential knowledge for anyone preparing for the USGBC LEED Green Associate certification exam.

It's important to note that retrocommissioning is distinct from fundamental commissioning (Cx) and life-cycle assessment. While these processes share some similarities, they focus on different aspects of building sustainability.

Data collection, functional tests, and analysis of systems' operations are all part of the retrocommissioning process. The retrocommissioning team develops and implements a plan for system improvements, repairs, calibrations, and operational changes based on the findings from these tests.

In essence, retrocommissioning makes buildings more suitable for current use, ensuring they operate efficiently and sustainably. For those interested in sustainable building practices, understanding retrocommissioning is a crucial step.
