Discussion

Overview
why commission
Better Buildings

Building owners are finding that the energy, water, and productivity savings achieved by commissioned buildings can offset the cost of the commissioning process. Studies indicate 8 to 20 percent savings in building operating costs over those in a non-commissioned building.

(Building Commissioning Guide, Version 2.2, GSA/DOE, dated July 30, 1998)

Why Commission?
why commission5
Better People

Aside from achieving documented cost savings and cost avoidance, commissioning enhances customer satisfaction by promoting proper training of the owner’s Operations & Maintenance staff, which increases the longevity and efficient operation of building systems.

Why Commission?
what is commissioning
A process of documentation, adjustment, testing, verification, and training, performed specifically to ensure that the finished facility operates in accordance with the owner’s documented project requirements and the construction documents.

It begins in pre-design and continues through design, construction, and the life of the facility.

(BCA draft document, 2004.)

What is Commissioning?
what is commissioning13
Design Intent Document

Details functional requirements and Owner’s expectations of how a building will be used and operated - OWNER’S PROJECT REQUIREMENTS

Basis for building commissioning

Basis of Design

The concepts, calculations, decisions, and product selections used to meet the OWNER’S PROJECT REQUIREMENTS

What is Commissioning?
what commissioning is not
Completing Standard Forms

Contractors’ QA/QC Program

Verification of the Contractors’ QA/QC Program

Construction Inspection

Construction Management Substitute

What Commissioning is NOT?
commissioning definitions
Commissioning Authority (CxA):

A person (or firm) representing the facility owner

Leader of the Commissioning Team

Authority of Cx Process – not design or means and methods

CxA not in chain of command – preserves objectivity

Commissioning Definitions
commissioning definitions16
Commissioning Provider (CP):

Independent Third-Party Commissioning Firm

A/E Firm

General Contractor

Construction Manager

Owner's Personnel

Commissioning Definitions
commissioning definitions17
Retro-Commissioning (RetroCx):

Commissioning an existing building that has never been commissioned

Re-Commissioning (ReCx):

Commissioning a building that has been previously commissioned

Continuous Commissioning (CCx):

Owner continues to collect and compare baseline data on selected building systems to ensure that the building functions optimally throughout its operating life

Commissioning Definitions
commissioning definitions18
Total Building Commissioning (TBCx)

Emphasizes that Commissioning is NOT only for the Mechanical and HVAC system, or any single system

Commissioning Team

Experts who, through coordinated actions, are responsible for carrying out the Commissioning Process

Commissioning Plan

A strategy overseen by the Commissioning Authority and prepared by the Commissioning Team

Commissioning Definitions
systems typically commissioned
Mechanical Systems

Heating, Ventilation and Air Conditioning (HVAC)

Building Automation Systems (BAS)

Fire Protection

Electrical Systems

Switchgear and Transformers

Future Commissioned Systems
objections to commissioning
“Haven’t I already paid for a quality building in my design and construction fees?”

Designer’s (A/E) services typically do not include field verification that their design works as intended.

Construction Manager’s services typically do not include functional verification that the installed systems meet design intent.

Objections To Commissioning
objections to commissioning22
“Isn’t the Commissioning Authority just a ‘bigger hammer’ for the owner to use to pound the designer and contractor?”

No. The CA must be a team builder by using the commissioning process to the benefit of all.

No. The CA should respect the traditional construction disciplines. The CA has a distinct responsibility to owner for system quality and performance.

Objections To Commissioning
objections to commissioning23
“Isn’t commissioning just another layer of inspection?”

The CA is not a layer, but a catalyst for communication that makes quality solutions possible.

The CA is not inspector (fault finder, accuser).

The commissioning process provides verification that Owner’s Project Requirements implemented in design and construction.

Objections To Commissioning
commissioning costs
Commissioning New Construction

Approximately 0.5%-1.5% of Total Construction Cost

Commissioning Existing Buildings (RetroCx)

Approximately 3.0% - 5.0% of Annual Operating Cost

(Building Commissioning Guide, Version 2.2, DOE/GSA, July 30, 1998)

Commissioning Costs
commissioning costs25
Commissioning New Construction

Approximately 2%-3% of Mechanical System Construction Cost – (BCA Case Studies)

Approximately 1%-2% of Electrical System Construction Cost – (BCA Case Studies)

Commissioning Costs
what does commissioning cost
Commissioning(Cx)

(New Construction)

0.5 to 1.5 Percent of Total Construction Cost

Retrocommissioning (RetroCx)

(Existing Construction)

3.0 to 5.0 Percent of Total Operating Cost

The Economics of Commissioning What Does Commissioning Cost?
  • An Initial Budget Setting Thumb-Rule:

2 % - 3 % of mechanical construction cost

plus

1 % - 2 % of electrical construction cost
