Continuous commissioning is the umbrella process that covers all the other forms of commissioning. It involves the building and its systems being continuously monitored, either via the BMS or through the use of dedicated logging devices. Systems can be re-commissioned or adjusted if performance isn't meeting requirements.
Continuous commissioning has become increasingly popular. The inherent flexibility of many contemporary buildings gives occupants the freedom to change their use of space, which may mean that the building services need to be adjusted or re-commissioned.
Continuous commissioning is made easier with the use of addressable control systems. Adjustments to lighting and heating and cooling setpoints can be made via a central computer, reducing the cost and disruption that often comes with conventional commissioning activities. This is typically a task that would come under a maintenance contract, although it can be useful to involve the original commissioning engineers.
All these activities make the gradual handover of full control of the building from the services and commissioning engineers to the facilities management team flow more easily. It gives the facilities team chance to get to know the systems fully, hopefully with the experts on hand to train and assist with problems that may arise.
From reviewing the processes used during the design, construction and occupation of the LCBP buildings, it appears that many people have the right intentions with regard to commissioning. However, with the traditional forms of contracts still in place, and practical completion and handover being the focal point of the project, commissioning is still often squeezed into a short period. Using a graduated handover approach, where the building is given time to settle down and enough time is allowed to commission all systems fully, is hugely beneficial to the client.
