Recommissioning (RCx) is the process of re-optimizing an existing building to ensure building equipment and systems are operating optimally to meet the current occupant’s needs. The focus is on identifying low-cost operational improvements to obtain energy savings.
On average, a building may expect to see a reduction in utility costs between five percent to 15 percent, often with a return on investment of fewer than two years. But the benefits go beyond energy savings and simple payback. There are a number of indirect benefits associated with re-commissioning, which include:
Improved Equipment Performance
Through the recommissioning process, each piece of equipment is tested to ensure it is functioning properly, any problem found is investigated, and solutions are recommended. Properly maintained equipment will last longer, operate more reliably, require fewer repairs and maintenance, and will also use less energy. Equipment that operates properly also demands less “crisis maintenance” from onsite staff and outside contractors, allowing staff to concentrate on their primary duties.
Lowered Operating and Tenancy Costs
The benefits can translate into increased profitability for building owners by reducing operating expenses that, lead to an increased net operating income and quicker returns on investment. Some properties can also be made more competitive by reducing the operating cost per square meter and lowering tenancy costs.
Improved Indoor Environmental Quality
Recommissioning can lead to improved quality of the building’s indoor environment as systems are adjusted to meet the needs of the current space. A good indoor environment can have positive effects on the health, comfort and productivity of its occupants.
Increased O&M Staff Capabilities and Expertise
A key aspect of the recommissioning process is providing training to building staff. When building staff increase their understanding of building equipment and troubleshooting skills, they are better able to operate and maintain equipment and respond to occupant requests without circumventing energy-saving strategies.
Improved Building Documentation
Up-to-date building documentation, including operation and maintenance manuals, sequences of operation, and system diagrams, are produced through the recommissioning process and are essential to maintaining and troubleshooting equipment.
When making a case for recommissioning, consider the impact all of the added benefits will have on your existing building.
