What is Commissioning? “Systematic process of assuring that a building is designed, constructed, and performs efficiently in Accordance with the design intent and the owner’s Operational needs, and that sets the structure to Continue these operations throughout the life of the building.” NEBB Standard

Improved Lifecycle Performance Energy Efficiency More Complex & Powerful Systems Changes in the Industry Building Systems Impact on Occupants Why is Commissioning Needed?

Commissioning for LEED BD+C Fundamental Commissioning vs. Enhanced Commissioning – Additional Design Reviews – Additional Submittal Reviews – Systems Manual – Warranty Phase Activities – Training Additional Activities for Commissioning Agent – Review of Building Energy Model – Implementation of M&V Plan – LEED Facilitation

1.What is Retro-Commissioning 2.Investigate Opportunities 3.Measurement and Verification 4.Retro-Commissioning Outcomes 5.LEED® Existing Building Retro-Commissioning

Focus more on optimizing existing systems In-depth look at controls and sequence of operations Space use changes Life safety and code updates Possible system upgrades Identify gaps between initial design and current operation What is Retro-Commissioning

Areas of High Complaint/High Use Lighting – in and out Parking HVAC Air balance Controls Chiller Boiler Kitchen Laundry Pool or spa Investigate Opportunities

Our Experience: Typical Opportunities

Measurement & Verification Verify identified opportunities were correctly implemented: – Performance Testing – Equipment Metering – System Trending Create New System / Equipment Benchmarks: – Perform ongoing reviews of performance – Maintain system parameters for performance – Annual assessment and testing

Outcomes – material changes implemented – Improved energy efficiency – Improved building performance – Identify Energy Conservation Measures for future investment – Documentation – Training Retro-Commissioning Results

Commissioning for LEED O&M LEED O&M V3 and Retro-Commissioning – Up to 6 LEED Credits – Energy Audits – Assistance in Greenhouse Gas Assessments – Refrigerant Reduction Calculations – Measurement and Verification – Training – Improved Operations

1.What is On-Going Commissioning 2.On-Going Commissioning Outcomes On-Going Commissioning

Utilize technology to continuously monitor and analyze building performance Continuous/ periodic feedback to building operators Operations adjusted/ maintenance activities initiated to immediately address performance issues On-Going Commissioning

Outcomes – Continuous improvement- energy efficiency and building performance – Issues identified quickly – More focused efforts for building operators On-Going Commissioning - Outcomes

National Gallery of Art Phased Renovation – New Construction 125,000 GSF per phase. Art Galleries, Restoration and Preservation Labs Major renovation of all HVAC, Electrical, Plumbing and Art Handling Systems. Case Studies Benefits and Outcomes: Improved performance and Reliability. Reduced equipment outages Early resolution of design issues.

University of Iowa Retrocommissioning Study Bowen Science Building 375,000 gsf of mixed use labs and offices Energy Savings Opportunities Replacing or retrofitting failed VAV boxes Upgrading the building automation system Installing an energy recovery system on exhaust systems Reducing lighting levels to current standards Potential energy savings of more than 35% with an average 2-year payback Case Studies

Proper Environmental Control Improved Indoor Air Quality Optimized Energy Profile Persistence of Savings Occupant Acceptance Certification/Accreditation Owner and Occupant Benefits

Commissioning Financial Incentives Median Costs – $0.30 per sq. ft [Existing Building] – $1.16 per sq. ft [New Construction] 13-16% energy savings Median payback period of 1.1 to 4.2 years – Lawrence Berkeley National Laboratory 2009 [
