| The cost of Commissioning is dependent on many
factors including a building’s size, complexity, HVAC
system type and whether the project consists of renovation,
modernization, or new construction. Commissioning of the HVAC
and Controls systems is most important to ensure occupant comfort,
energy efficiency, and maintainability. These costs, for new
construction, will range from 1.5% of the mechanical system
installed cost for larger buildings (over 40,000 sq. ft.) to
2.5% for smaller buildings (20,000 to 40,000 sq. ft.) In most
buildings, the mechanical systems represent 20% of the total
construction hard costs, so the mechanical commissioning is
only 3/10ths to 5/10ths of one percent of the total construction
hard costs. This is far less than the cost included in a car
or computer for the quality control and testing component that
makes those machines so reliable.
 The
electrical power and fire alarm systems are also lacking for
quality control in most projects. Since they have more significant
life safety concerns, they receive some of their commissioning
from building code inspectors and insurance companies. But
they do need additional commissioning due to the interaction
between the fire alarm/smoke control system and the HVAC systems.
These commissioning costs are less than 1/10th of one percent
of total construction hard costs.
