Why Commission? Southeast Region Chapter 2004 Summer Training Meeting Louisville, Kentucky Thursday, August 19, 2004

Why Commision? 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*. *Source: Building Commissioning Guide, Version 2. 2, GSA/DOE, dated July 30, 1998 Southeast Region Chapter 2004 Summer Training Meeting Louisville, Kentucky Thursday, August 19, 2004

Why Commision? Better People Aside from achieving documented costs savings and cost avoidance, commissioning enhances customer satisfaction and assures proper ongoing training of the facility Operations & Maintenance personnel.

What Does Commissioning Cost? The Economics of Commissioning If planned correctly and implemented early enough in the design process, commissioning can be included with little or no cost impact*. Without Commissioning Design Phase Costs Construction Phase Costs First Year Warranty Period Costs With Commissioning Design Phase Costs Construction Phase Costs First Year Warranty Period Costs * Based on research findings from University of Wisconsin, ASERTTI Training Module, 1998 Southeast Region Chapter 2004 Summer Training Meeting Louisville, Kentucky Thursday, August 19, 2004

What Does Commissioning Cost? The Economics of Commissioning An Initial Budget Setting Thumb-Rule-- 2 % - 3 % of mechanical construction cost plus 1 % - 2 % of electrical construction cost (Source: BCA. Based on six science building projects) Southeast Region Chapter 2004 Summer Training Meeting Louisville, Kentucky Thursday, August 19, 2004
