Topics Overview of Commissioning Sustainable & High Performance Buildings Commissioning for High Performance Recent trends in Commissioning
Definitions of Commissioning Official definition*: My definition: “Systematic process of assuring by verification and documentation, from the design phase to a minimum of one year after construction, that all facility systems perform interactively in accordance with the owner’s operational needs, including preparation of operation personnel.” “It’s the Owner’s QA/QC process.” * Official definition of Total Building Commissioning established by the National Conference on Building Commissioning
Types of Commissioning New Building Commissioning Process Commissioning Technical Commissioning Existing Building Commissioning Re-Commissioning Retro-Commissioning Continuous Commissioning® Ongoing Commissioning Monitoring-Based Commissioning ® Registered trademark of Texas A&M Energy Systems Laboratory
Why do we recommend Commissioning? • Building Owner’s QA/QC process • Helps meet sustainability / high performance building goals • Enhances reliability of complex systems • Ensures comfortable, healthy environments for tenants and employees • Facilitates efficient system operations yielding energy savings
What are the motivating factors for end users? LEED points Reliability (Data Centers, Hospitals, Labs) Improved Comfort Reduced Energy Consumption / Incentives Mandates (Codes and Ordinances)
Measureable Benefits of Cx $4.00 Owners can achieve savings in operations of over the first years of occupancy 5 as a direct result of every invested in commissioning* $1.00 * Data from Whole Building Design Guide – a program of National Institute of Building Sciences (06-21-2010)
Commissioned buildings utilize less energy than non-commissioned buildings* In many cases, this savings alone may more than pay for the entire commissioning process.

Commissioning Certifications & Guidelines • ACG (AABC Commissioning Group) • Certified Commissioning (CXA) Authority • ACG Commissioning Guideline • Dedicated to the advancement of professional, independent commissioning services through education, training, and certification of qualified architects and engineers ASHRAE • Commissioning Process Management Professional (CPMP) • ASHRAE / NIBS Guideline 0 – 2005 “The Commissioning Process” • ASHRAE / NIBS Guideline 1 – 2007 “HVAC Technical Requirements for the Commissioning Process” • ASHRAE / ANSI Standard 2012 – 2013 “Commissioning Process for Buildings and Systems”
Commissioning Certifications & Guidelines • NEBB(National Environmental Balancing Bureau) • BSC Certified (Building Systems Commissioning) • NEBB Procedural Standards for Building Systems • Established in 1971, standards for: • Testing, adjusting and balancing (TAB) • Commission and retro-commission building systems commissioning • Sound and vibration testing • Test and certify laboratory fume hoods/cleanrooms BCA (Building Commissioning Association) • Certified Commissioning Professional (CCP) • The Building Commissioning Handbook
Commissioning Certifications & Guidelines ICC (International Code Council) ICC G4-2012 Guideline for Commissioning NECA (National Electrical Contractors Association) Origins back to 1901 NECA 90- Recommended Practice for Commissioning Building Electrical Systems NFPA 70 NEC Article 708 – Critical Operations Power Systems
Cost of Commissioning • Depends on the following: • Project size • Complexity of building systems • Systems to be commissioned • Typically less than 1% of total construction cost
Sustainable Bldg Guidelines & Best Practices • US Green Building Council • LEED • European Green Building Councils • BREEAM • Estidama • Pearl Rating System • World Green Building Council • No independent rating system
Commonality in All Rating Systems COMMISSIONING
High Performance BldgGuidelines & Best Practices • ASHRAE • Standard 90.1-2013 – Energy Standard for Buildings Except Low-Rise Residential Buildings • Standard 55-2013 – Thermal Environmental Conditions for Human Occupancy • Standard 62.1-2013 – Ventilation for Acceptable Indoor Air Quality • Standard 189.1-2011 – Standard for the Design of High-Performance Green Buildings • Green Guide 4th Edition – Design, Construction, and Operation of Sustainable Buildings • EPA Energy Star • Portfolio Manager • NIBS • Whole Building Design Guide
What’s the difference… “Green”, “Sustainable”, “High Performance”? • NIBS - High Performance Building Council: • “A building that integrates and optimizes all major high-performance building attributes, including energy efficiency, durability, life-cycle performance, and occupant productivity” • ASHRAE Guideline 32 - Sustainable High-Performance Operations and Maintenance • A high-performance building “consistently delivers a highly productive environment without wasting resources” • Environmental Protection Agency • “Green building is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle from siting to design, construction, operation, maintenance, renovation and deconstruction. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building is also known as a sustainable or high performance building.”
So………………? • Overview of Commissioning • Sustainable & High Performance Buildings
Commissioning of New High Performance Buildings Start at the beginning!!! BUT, “Begin with the end in mind” Stephen Covey “If you don’t know where you are going, you will probably not wind up there.” Forrest Gump
Commissioning of New High Performance Buildings • Emphasis on Owner’s Project Requirements (OPR) • Decisions based on life cycle cost • What benchmark or Rating System to use?
Sustainable or Green Features • Emphasis on Design Phase • Sophisticated HVAC controls with optimized sequences • Sophisticated lighting controls • Condensate recovery systems • Rainwater collection and reuse • Low flow plumbing fixtures • Renewable energy sources such as photovoltaic (PV) systems • Building envelope: Design reviews and field testing • Indoor Air Quality (IAQ): Ventilation that meets or exceeds ASHRAE 62.1 • Natural lighting & light pollution • System performance benchmarking
Commissioning of Existing Buildings for High Performance Start at the beginning!!! BUT, “Begin with the end in mind”
Commissioning of Existing Buildings for High Performance • Emphasis on Planning and Investigation Phases • Determine the Current Facility Requirements (CFR) • What are the motivating factors for EBCx? • Energy Reduction • LEED Points • Occupant complaints • Code or Ordinance Requirements • Utility Incentive • What benchmark or rating system to use? • LEED EB • EPA Energy Star • Labs21
Commissioning of Existing Buildings for High Performance • Extensive use of Baselines and Benchmarking • “Normalizing” data • Energy Use Intensity (EUI) • Power Usage Effectiveness (PUE) • Measurement & Verification Plan (M&V Plan) • BAS Trend Logs (Monitoring based Cx) • Whole building meter data or sub-meters? • Methodology for repairs & upgrades • Fault detection and diagnostics (FDD)
