June 13, 2011 Commissioning What is Commissioning? A planned, documented, and managed engineering approach to the start-up and turnover of facilities, systems, and equipment to the end- user that results in a safe and functional environment that meets established design requirements and stakeholder expectations. A process which ensures discovery of flaws in the design or construction that preclude facility operation in accordance with parameters set forth by the owner and developer. Management of the “Completion of Construction” process.
June 13, 2011 Why Commissioning? Building System Complexity Building systems comprised of many different components. Energy efficiency, redundancy, Building Automation Systems create complex system operations. Procurement Philosophies Components are designed, fabricated and installed by more than one responsible party. Trends of CM and Owners towards pre-purchasing equipment and breaking up traditional single source mechanical and electrical trades. Schedules for facility delivery often require accelerated activities. Value engineering results in system component compromises. Transfer of Knowledge Training and turn-over is critical to post occupancy operations. Commissioning
June 13, 2011 Retro-Commissioning Retro-Commissioning (RCx) is a systematic, documented process that identifies low cost operational and maintenance improvements in existing buildings and brings the buildings up to the design requirements of its current use. Focus on energy-using equipment, such as mechanical equipment, lighting and related controls and usually optimizes existing system performance, rather than relying on major equipment replacement. www.green.ca.gov The Value of Existing Building Commissioning
June 13, 2011 Research Findings Research conducted by Lawrence Berkley National Laboratory Evan Mills, Ph.D. Report Prepared for The California Energy Commission Public Interest Energy Research (PIER) New and Existing Building Commissioning Analysis of 643 Buildings Over 99 Million SF 26 States Represented
June 13, 2011 Key Findings (1 of 2) Commissioning is arguably the single-most cost-effective strategy for reducing energy, costs, and greenhouse-gas emissions in buildings today. Energy savings tend to persist well over a 3- to 5-year timeframe, but data over longer time horizons are not available. Median commissioning costs: $0.30/sf and $1.16/sf for existing buildings and new construction, respectively (and 0.4% of total construction costs for new buildings). Median whole-building energy savings: 16% and 13%. Median payback times:1.1 and 4.2 years.
June 13, 2011 Actual RCx Costs DescriptionValues or Ranges Total RCx Cost$0.13 to $0.45/sqft Provider Fee as % of Total RCx Cost35-71% Average RCx Cost Allocation Planning and Investigation 69% Implementation 27% Verification, Tracking and Reporting 4% Simple Payback Time0.2 to 2.1 years
June 13, 2011 Large reductions in greenhouse-gas emissions are achieved. High-tech buildings particularly cost-effective, and saved large amounts of energy due to their energy-intensiveness. The database incorporates the work of 37 commissioning providers. Non-energy benefits are extensive and often offset part or all of the commissioning cost. Key Findings (2 of 2)
Depth of commissioning versus savings achieved (existing buildings)
June 13, 2011 Barriers Commissioning is an underutilized strategy for saving energy and money and reducing greenhouse gas emissions while managing related risks. Reasons for this underutilization: Widespread lack of awareness of need and value on the part of prospective customers. Splintered activities and competition among a growing number of trade groups and certification programs. Misperception that it is not cost-effective in smaller buildings, The absence of commissioning-like requirements in most building codes. Omission of RCx strategy in most energy-efficiency potentials studies. Tension between standardization and recognition that each building is unique and must be approached with an open mind.
