Technical systematic process of verifying
and testing Building Systems
TOTAL QUALITY ASSURANCE!

It applies to the Building Design
It applies to the Construction of the Building
It applies to the turnover of the building


Systems perform as intended
Lower energy use and cost
Early detection of potential problems
Better building documentation (Systems Manual)
Trained building operators
Lower Operations & Maintenance (O&M) cost
Enhanced Indoor Environmental Quality (IEQ)
Reduced construction costs (<Change Orders)

Economics of Cx

The operating costs of a commissioned
building are 8 – 20% lower than a
comparable non-commissioned building
(GSA Building Commissioning Guideline)
Other benefits of Cx

Reduced change orders.
–

Reduce RFI’s
–

0.5% - 10% of total MEP change orders
RFI’s turn into change orders $$$
Improved occupant comfort = Productivity

Simple
Complex
Commissioning cost can
vary considerably from
project to project.
Actual cost depend on:

Project size

Project complexity

Rigor of Cx effort
The question is not
whether you can
afford to Cx? But,
can you afford not
to?
Cx – The Bottom Line

Cx adds value.

features that have a potential of
being over-ridden or removed
due to lack of understanding.




After handover ( 6 – 10 months)
review performance of
building/facility with owner and O&M
staff.
Create a deficiencies list (prior to
manufacturer / contractors warranty
expiration)
Any items listed on the deficiencies
list that will not be corrected shall be
documented in the Systems Manual

CxA conducted design review
CxA reviewed submittals

O&M staff and occupants have been trained
CxA review of building operation post-occupancy
USGBC’s CxA inerpretations


CxA for Cre-3 has to be independent, cannot be
hired by design or construction team
Late in the game.
–

If owner commits to LEED late it is acceptable to provide
two reviews during and after CD’s in lieu of reviews at SD
and CD
For prototype buildings:
–
–
Reviews are acceptable after SD
2 reviews are to be performed on latter stages of design.
