If you commission nothing else in a new or renovated building, be sure to consider commissioning the humidification and dehumidification systems. The fact that a project includes active humidification and/or dehumidification controls means that the proper operation of those systems is critical to the facility owner. These systems cost more to install and will cost more to operate throughout the life of the building. An owner will not choose to include them without a good reason to justify the expense.
The benefits of commissioning humidification and dehumidification systems are verification that they function as intended (i.e., the owner gets what they are paying extra for) and that they do so as efficiently and inexpensively as possible (i.e., the owner will not have to pay more than necessary to achieve their desired environmental control in the future).
