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)ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupWhy Commission?Better People Aside from achieving documented cost savings and cost avoidance, commissioning enhances customer satisfaction by promoting proper training of the owners Operations & Maintenance staff, which increases the longevity and efficient operation of building systems.ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupACG CxA WORKSHOP WEBINAR Facility Commissioning GroupACG CxA WORKSHOP WEBINAR Facility Commissioning GroupACG CxA WORKSHOP WEBINAR Facility Commissioning GroupACG CxA WORKSHOP WEBINAR Facility Commissioning GroupACG CxA WORKSHOP WEBINAR Facility Commissioning GroupACG CxA WORKSHOP WEBINAR Facility Commissioning GroupWhat is Commissioning?A process of documentation, adjustment, testing, verification, and training, performed specifically to ensure that the finished facility operates in accordance with the owners 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.)ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupWhat is Commissioning?Design Intent Document Details functional requirements and Owners expectations of how a building will be used and operated - OWNERS PROJECT REQUIREMENTS Basis for building commissioningBasis of Design The concepts, calculations, decisions, and product selections used to meet the OWNERS PROJECT REQUIREMENTSACG CxA WORKSHOP WEBINAR Facility Commissioning GroupWhat Commissioning is NOT?

Exterior Envelope Roofing Systems Structural Systems Interior Systems Elevator Systems Plumbing Systems Lighting Systems Electrical Systems Fire Protection Systems Telecommunication SystemsACG CxA WORKSHOP WEBINAR Facility Commissioning GroupObjections To Commissioning“Havent I already paid for a quality building in my design and construction fees?” Designers (A/E) services typically do not include field verification that their design works as intended. Construction Managers services typically do not include functional verification that the installed systems meet design intent.ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupObjections To Commissioning“Isnt 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.ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupObjections To Commissioning“Isnt 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 Owners Project Requirements implemented in design and construction.ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupCommissioning CostsCommissioning New Construction Approximately 0.5%-1.5% of Total Construction CostCommissioning Existing Buildings (RetroCx) Approximately 3.0% - 5.0% of Annual Operating Cost(Building Commissioning Guide, Version 2.2, DOE/GSA, July 30, 1998)ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupCommissioning CostsCommissioning New Construction Approximately 2%-3% of Mechanical System Construction Cost (BCA Case Studies) Approximately 1%-2% of Electrical System Construction Cost (BCA Case Studies)ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupCommissioning(Cx)(New Construction)0.5 to 1.5 Percent of Total Construction CostRetrocommissioning (RetroCx)(Existing Construction)3.0 to 5.0 Percent of Total Operating CostSource: Building Commissioning Guide, Version 2.2, DOE/GSA, July 30, 1998What Does Commissioning Cost?ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupThe Economics of Commissioning An Initial Budget Setting Thumb-Rule:2 % - 3 % of mechanical construction costplus1 % - 2 % of electrical construction cost(Source: BCA. Based on six science building projects.) What Does Commissioning Cost?ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupThe Economics of Commissioning* Based on research findings from University of Wisconsin,ASERTTI Training Module, 1998 If planned correctly and implemented early enough in the design process, commissioning can be included with little or no cost impact*.Without Commissioning With CommissioningDesign Phase CostsConstruction Phase Costs First Year Warranty Period CostsDesign Phase CostsConstruction Phase Costs First Year Warranty Period CostsWhat Does Commissioning Cost?ACG CxA WORKSHOP WEBINAR Facility Commissioning GroupASHRAE Guideline 11.
