Question
What is the process that is performed on existing buildings to identify and recognize system improvements that make the building more suitable for current use?
A. Energy modeling
B. Retrocommissioning
C. Life-cycle assessment
D. Fundamental Commissioning (Cx)
Answer
B. Retrocommissioning
Explanation
Retrocommissioning is a process applied to existing buildings to ensure that they continue to perform optimally for the current use. This process involves checking systems to see if they function as intended, making necessary repairs or improvements, and ensuring that building staff are trained in the operation and maintenance of systems.
Retrocommissioning is a systematic process that is performed on existing buildings to identify opportunities for improving the performance and efficiency of building systems. The goal is to optimize these systems to make the building more suitable for its current use and occupancy.
During retrocommissioning, a team of experts thoroughly examines the building's mechanical, electrical, and plumbing systems, as well as its automation and control systems. They collect data, perform functional tests, and analyze the systems' operations to identify deficiencies, malfunctions, or areas where performance can be enhanced.
Based on their findings, the retrocommissioning team develops and implements a plan for system improvements, repairs, calibrations, and operational changes. These measures are designed to boost energy efficiency, reduce maintenance costs, extend equipment life, and improve occupant comfort and productivity.
In the context of LEED, retrocommissioning contributes to the Existing Buildings: Operations & Maintenance (EBOM) rating system. It helps building owners and managers ensure their properties continue to perform optimally and sustainably over time.
The other options are related but distinct concepts:
A. Energy modeling - A computer simulation tool used to predict a building's energy performance during design.
C. Life-cycle assessment - An analysis of the environmental impacts of a product or process over its entire life span.
D. Fundamental Commissioning (Cx) - A process focused on verifying that a new building's systems are installed and functioning according to the owner's requirements and design intent.
So in summary, retrocommissioning is the process specifically focused on evaluating and improving the performance of existing building systems to optimize their suitability for current use. It is an essential tool for maintaining and enhancing the sustainability of our built environment over time.
