Retro-Commissioning
By going back to basics to assess what is working well and what may need replacement, Technical Retro-Commissioning of Existing Buildings is the thorough compilation of building data and analysis, as well as providing strategic planning and execution.
From data collection and field verification to testing, analyzation, and documentation of facts, this discipline aims to provide optimal performance.
What is Retro-Commissioning?
Retro-commissioning (RCx) is defined as the process of systematically inspecting and optimizing an existing building’s systems and equipment to ensure they operate efficiently and effectively according to the current operational needs. Unlike initial commissioning, which occurs during a building’s construction phase, retro-commissioning is performed on buildings that have been in use for some time.
The aim of RCx is to identify and correct issues that might have developed since the building’s completion, such as equipment degradation, system changes, or operational inefficiencies, thereby improving overall performance, reducing energy consumption, and enhancing occupant comfort.
The Benefits of Retro-Commissioning
- Improves energy efficiency and reduces utility costs
- Enhances indoor air quality and occupant comfort
- Extends the lifespan of building systems and equipment
- Identifies and resolves operational issues
- Lowers maintenance and repair expenses
- Provides better understanding and control of building systems
- Increases overall building performance and reliability
- Contributes to sustainability and environmental goals
- Leads to a significant return on investment
- Helps comply with energy and building performance regulations
Why Retro-Commissioning Certification?
Retro-Commissioning (RCx) is a significant business opportunity for contractors, TAB professionals, Engineering and Commissioning firms correcting under-performing buildings, improving indoor environment and comfort, and optimizing energy usage for aging facilities.
Technical Retro Commissioning of building systems drives deep, lasting energy savings for owners and managers of existing buildings by taking a holistic approach to energy efficiency. It covers building systems, energy using equipment, operating schedules, and optimizes how these elements perform together.
NEBB’s Technical Retro-Commissioning for Existing Buildings program provides certification of firms and individuals that meet the criteria established by NEBB.
