  7. 7. Quality and Building Energy Management Moreno Tagliapietra – © 2013 PlaNYC Green Buildings LL85 NYC Energy Conservation Code Requirements: “For all additions, alterations, renovations and repairs* to an existing building or building system, the work must meet the current standards of the NYC Energy Conservation Code (NYCECC) at the time of construction” * Of any size, previously 50% of the building or more 7
  8. 8. Quality and Building Energy Management Moreno Tagliapietra – © 2013 PlaNYC Green Buildings LL87 “LL87 requires buildings 50,000 gross square feet or more to undergo an energy audit once every 10 years, along with retro-commissioning to "tune up" the building's existing energy systems and ensure efficient operation. “ 8 Parallels with quality management: Continuous Improvement
  9. 9. Quality and Building Energy Management Moreno Tagliapietra – © 2013 PlaNYC Green Buildings LL88 Lighting Upgrades and Sub-Metering “LL88 requires 50,000 gross square feet or more, non-residential buildings to upgrade lighting to meet current New York City Energy Conservation Code standards, and to install electrical sub-meters for each 10,000 square feet non-residential tenant space and provide monthly energy statements” Deadline for compliance is January 1, 2025 Note: in particular, the code includes requirements for occupancy and/or vacancy sensors and daylight harvesting 9

  11. 11. Quality and Building Energy Management Moreno Tagliapietra – © 2013 “Total Building Commissioning is a systematic process of assuring by verification and documentation, from the design phase to a minimum of one year after construction1 , that all facility systems perform interactively2 in accordance with the design documentation and intent, and in accordance with the owner’s operational needs3 , including preparation of operation personnel4 .” New Buildings: General Services Administration/GSA Total Building Commissioning/TBCx Parallels with quality management: 1. TBCx assures that best industry practices are used cradle to grave 2. The building must be handled as a network of interactive systems 3. TBCx is driven by Owner’s Project Requirements and Design Intent documents 4. TBCx includes operators development 11
  12. 12. GSA TBCx – Planning Stage 1 - Identification of the commissioning team:  GSA PM (Team Leader)  GSA Operating Personnel  Customer Agency Representative(s)  GSA Technical Experts (i.e. Structural, Mechanical, Electrical, Fire Protection, Elevator, Seismic, LEED/Sustainability, etc.)  Architect/Engineer (A/E)  Construction Manager (CM)  Commissioning Agent (CxA)  Construction Contractor and Subcontractors Parallels with quality management: Concurrent Engineering Quality and Building Energy Management Moreno Tagliapietra – © 2013 12
  13. 13. GSA TBCx – Planning Stage 2 - Define Owner's Project Requirements  The Owner’s Project Requirements will form the basis from which all design, construction, acceptance and operational decisions are made Parallels with quality management: Customer Focus Quality and Building Energy Management Moreno Tagliapietra – © 2013 13
  14. 14. GSA TBCx – Planning Stage 3 – Develop Preliminary Commissioning Plan Introduction Purpose and general summary of the Plan. General Project Information Overview of the project, emphasizing key project information an delivery method characteristics. Commissioning Scope The commissioning scope including which building assemblies, systems, subsystems and equipment will be commissioned on this project. Team Contacts Project specific Commissioning Team members and contact information. Communication Plan & Protocols Documentation of the communication channels to be used throughout the project. Commissioning Process Detailed description of the project specific tasks to be accomplished during the Planning, Design, Construction and Tenant Occupancy Stages with associated roles & responsibilities. Commissioning Documentation List of commissioning documents required to identify expectations, track conditions and decisions and validate/certify performance. Commissioning Schedule Specific sequences of events and relative timeframes, dates and durations. Quality and Building Energy Management Moreno Tagliapietra – © 2013 14
  15. 15. GSA TBCx – Planning Stage 4 - Establish Initial Budget for Commissioning Commissioning agent costs Additional project costs Cost-benefit analysis for commissioning Quality and Building Energy Management Moreno Tagliapietra – © 2013 15
  16. 16. GSA TBCx – Design Stage “Design Stage commissioning activities serve to ensure that the Owner’s Project Requirements for items such as energy efficiency, sustainability, indoor environmental quality, fire protection and life safety, etc. are sufficiently defined and adequately and accurately reflected in the contract documents.” Incorporate commissioning in the Architect/Engineers and Construction Managers scopes of work Retain Commissioning Agent Services Review Owner Requirements and Design Commissioning Agent review of design documents Update commissioning plan Develop commissioning specifications Quality and Building Energy Management Moreno Tagliapietra – © 2013 16
  17. 17. GSA TBCx – Construction Stage “The Commissioning Team collaborates during the Construction Phase to verify that systems and assemblies operate to validate that the Owner’s Project Requirements are achieved. The two overarching goals of this phase are to assure both the level of quality desired and the requirements of the contracts are met.” Review submittals for performance parameters Develop and use construction checklists Oversee and document function performance tests Hold Cx team meetings and report progress Conduct owner training Turnover commissioning record Quality and Building Energy Management Moreno Tagliapietra – © 2013 17
  18. 18. GSA TBCx Post-Construction Stage “Systems, assemblies, equipment and components will tend to shift from their as-installed conditions over time. In addition, the needs and demands of facility users typically change as a facility is used. The Post- Construction Stage allows for the continued adjustment, optimization and modification of building systems to meet specified requirements.” Perform deferred and seasonal testing Re-inspect performance before warranty end Complete final commissioning report Final satisfaction review with client Quality and Building Energy Management Moreno Tagliapietra – © 2013 18
  19. 19. Existing Buildings Energy Efficiency Programs  Energy Audits*  Retro-Commissioning/RCx*  Continuous Commissioning (continuous systems improvement)  Building re-tuning (limited scope retro-commissioning focused on control systems sensor checking/replacement, set-points validation and system calibration) * Energy audits identify opportunities for efficiency improvements in an existing building and one of these opportunities is frequently the need for a building “tune-up,” or retro- commissioning (but, historically, energy audits tend to focus on capital investment) Quality and Building Energy Management Moreno Tagliapietra – © 2013 19
  20. 20. Energy Efficiency Programs Common Tasks  Develop equipment inventory  Collect all documentation including Owner’s Project Requirements, operating manuals, installation schedules, blueprints, maintenance records, and previous audit reports  Identify building’s types of energy (electricity, fuel oil, natural gas, city steam)  Analyze energy bills  Identify major loads  Allocate energy use to major loads  Compare systems performance against requirements, benchmark  Identify Energy Efficiency Measures/EEM’s  Calculate EEM’s life cycle costs and savings and prioritize EEM’s* *Includes elements of Quality Costs Quality and Building Energy Management Moreno Tagliapietra – © 2013 20

  22. 22. Building Energy Efficiency Main Tenets   Consume energy only when it is necessary (if you don’t use it, turn it off).  At any given time, consume only the energy that is necessary (match capacity to demand, typical issues with oversized equipment).  Use high efficiency equipment and maintain it well.  Use a Building Automation (or Management) System to achieve systems integration. Energy use = equipment consumption x hours of operation Hydronic Boilers Modulating Control Quality and Building Energy Management Moreno Tagliapietra – © 2013 22
  23. 23. Building Energy Efficiency Typical Issues   Schedule: equipment is running when there is no demand (especially HVAC, lights and plug-in loads) Systems: Untrained personnel. Oversized equipment (boilers, fans, pumps). Inefficient equipment. Malfunctioning controls (dead sensors, out-of calibration controllers, wrong set points, manual bypasses). Inadequate maintenance (run to failure, cleaning, lubrication, alignment, filter replacement, parts replacement, etc.) High electricity demand Poor energy purchasing practices Combustion analyzer Quality and Building Energy Management Moreno Tagliapietra – © 2013 23
  24. 24. Building Energy Efficiency Typical Issues  What is the most common and most commonly neglected EEM? Quality and Building Energy Management Moreno Tagliapietra – © 2013 24 Preventive maintenance! A preventive maintenance program requires an exhaustive equipment inventory, the collection of all related documentation - manuals, installation schedules, blueprints, previous maintenance/repair records, etc. -, an overhaul of underperforming equipment, and then the proper maintenance program including the collection and trend analysis of history records
  25. 25. Building Energy Efficiency Final Words   Quality and Building Energy Management Moreno Tagliapietra – © 2013 As every professional promoting (positive) change in his/her organization can tell you, if building ownership and management are not on-board, achieving code compliance is an uphill battle and more proactive energy efficiency initiatives outright impossible For your EEM proposals to have a chance of being taken into serious consideration, present your case with an air- tight evaluation of life cycle costs and savings 25
