Ideally, a building will be recommissioned regularly, about every three to five years. One of the final steps of a recommissioning process should be to schedule the next cycle. If you haven't recommissioned yet, or your last recommissioning project didn't include a timeline for the next one, how will you decide when you should recommission your building?
If more than one of the following conditions exists, you may want to consider implementing a recommissioning process:
- increase of more than 10 percent in energy use
- increased occupant complaints about comfort
- significant changes to occupancy schedules (especially on evenings, weekends and holidays)
- issues that maintenance staff don't know how to fix
- frequent equipment or component malfunctions
- significant changes to building use or layout
- replacement of major equipment (heating, ventilation and air-conditioning system, boilers, water chillers, etc.)
- Significant turnover in operations staffFootnote 1
