1、Commissioning ReportEnergy SolutionBuilding EfficiencyJohnson Controls Inc.1Executive SummaryGuo Rui Real Estate Development Co. Limited. contracted Johnson Controls Inc. to provide LEED Fundamental and Enhanced commissioning services for thenewfacilityinEconomic-TechnologicalDevelopmentArea.Thecomm

2、issioning team worked with the project management, design team as well as the construction team to help install and set up the building energy consuming systems for optimal performance with the requirement of LEED rating system.During the LEED commissioning process, the Johnson Controls commissionin

3、g team identified numerous deficiencies from the design phase to the construction phase and delivery and acceptance phase.Commissioning bridges the gaps between design, construction and facility operators. The intent is to deliver a better quality project. The effect of properly executed commissioni

4、ng is to give the owner peace of mind during the critical initial occupancy,prevent system operation issues froming long term problems for buildingowner and prevent contractors from having to respond to repeated call backs.With productive work during the entire commissioning process, Johnson Control

5、s achieve the final commissioning report (this document) and lots of documentations submitted as Appendixs.2The Commissioning ProcessThe commissioning activities for this project began in 2009 with design reviews and included more than a dozen site visits/meetings that spanned between Jan of 2010 an

6、d July of 2014. The actual commissioning process began prior to the first field visitwith a review of the design development and construction documents.JohnsonControls also reviewed equipment and control submittals.The commissioningprocess was sustained between each field visit with phone conversati

7、ons and correspondence that provided support to the team.Theprojectteamregularlyparticipatedinon-siteconversationswiththecommissioning authority.When all contractors, not only teral MEPcontractors embrace this philosophy the project usually finishes with higher quality and fewer delays. The commissi

8、oning plan and specification for this project are included in Appendix A & B.A large portion of the commissioning effort was aimed at assisting the construction team with installation and control issues. The issues ranged from installations and control that would have made the HVAC equipment ope

The progress reports providedetailed descriptions observed.oftheissuesandthemendedresolutionsastheywere3Design Review SummaryOne of the key success factors to commissioning a building is early involvement by

10、the Commissioning Authority. The Commissioning Authority can begin review of the project documents during the design phase or the construction phase depending on the specific project scope of work. At a minimum, the Commissioning Authority (CxA) should review the Construction Documents before actual

11、 construction begins on any of the systems to be commissioned.As part of the design phase review, the CxA reviews the project documents and verifies that they are consistent with both the Basis of Design (BOD) and the Owners Project Requirements (OPR). The OPR is a summary of what the Owner wants fo

12、r the project. The BOD is a summary of how the design team intends to deliver what the Owner wants. Sometimes the OPR and BOD are quite formalized. In other cases the design intent is less formalized, documented by meeting minutes and various correspondences, instead of a stand-alone document. The C

13、xA seeks out design intent documents, in whatever form they exist, with the purpose of understanding the design intent as accurately as possible; in order to generate the most relevant and valuable design review possible.For the OPR, Johnson Controls has following comments:1.LEED Target Goal mention

If possible, the submittal review by the Com

21、missioning Authority coincides with the submittal review by the design team.This review by the commissioning authority has two main purposes. The first is to make sure the equipment intended for the project will meet with the Owners Project Requirements. The second purpose is for the development of

22、the project-specific Installation Checklists and Functional Performance Test forms.The design team is responsible for ensuring the equipment is in full compliance with the project specifications. The CxA review has a somewhat different review focus as verifying the operation and maintenance of equip

23、ment and system.All of the submittals provided to Johnson Controls for review had already been approved by the project management team. Johnson Controls had several comments that were adequately addressed by the contractors or explained by the Engineer. The Appendix D identifies some of the submitta

24、ls approval information.Some of the submittal related issues where the Commissioning Authority was able to give valuable input to the design and construction teams include:üüüEquipment Model should be indicatedControl sequence and points list should be updated with the complete system

25、 Operation sequence for chiller and AHU should be updated6Verification of Installation and PerformanceAs part of the commissioning process, the Commissioning Authority helped in developing project specific pre-functional checklist and functional test procedure foreach piece of equipment and systems

26、to be commissioned.The purpose ofpre-functional test and functional performance verification are to ensure that each piece of equipment or system operates according to the design intent and the owner project requirements.The functional verification tests occur after the construction team has documen

27、ted start up and successful completion of the pre-functional test for a particular piece of equipment or system.The pre-functional tests are designed to make sure each individual component of a larger piece of equipment such as an air handling unit operates as required. Each individual component is

28、measured on a simple pass / fail grading system. Once all individual components have passed, the larger piece of equipment is considered passed from a pre-functional test stand point.The functional verification tests are designed to make sure the equipment or system operation as a whole performs as

29、designed. An example of the type of testing that is verifying that the supply air temperature reset program for an air handling unit operates properly while still maintaining the design conditions in the space served bythe unit.Functional testing verifies the unit can provide the cooling, heating,pr

30、essure, air volume, fluid volume, etc. capacity as required by the design documents. In addition it also verifies that all modes of operation perform as required. Functional tests are measured on a simple pass / fail grading system.The pre-functional test of this project was began from December 2013

31、 to February 2014, and there were a few failures. The contractors had a chance to remedy the deficiencies from the former tests. The functional verification tests were done in March to April 2014. The main problems occurred in this project are focus on following items, and a summary documentation is

32、 attached as Appendix E.Ø Equipment label should be indicated more clearly;Ø Wiring work of BAS system should be paid more attention and double-check;Ø Control sequence and operation strategy of AHU need to be optimized.7At the time of this report, all the issues have been fixed with

33、the owners requirement. Restricted by the climate condition, some of the performance test, such as chiller performance, chiller plant control strategy, etc, can not be conducted and has been defered to summer season during the revisit period after occupancy.8Training Review SummaryProper training fo

34、r individuals that will be responsible for operating and maintaining building systems is important to making sure the system performance achieved at thetime of occupancy continues into the future.This speaks to the concept ofsustainable energy efficient performance of the commissioned systems.Traini

35、ng occurred on this project from January to April 2010. The owner / user were trained on the systems and main equipments on the project. The commissioning team reviewed training agendas and attended some training sessions to insure that the training went smoothly. All training sessions appeared to b

36、e very informative to the users and staff.JOHNSON CONTROLS has requested documentation showing the End Users were trained in operation and maintenance of the commissioned systems. This includes sign in sheets showing who was trained and agenda showing what was covered. Atthe time of Appendix F.thisr

37、eportdocumentationoftraininghadbeenprovidedshowedin9System Manual SummaryTo help the project to conduct daily operation and maintenance in the future, Johnson Controls has compiled a System Manual which combined with the O&M Manual from contractor. The System Manual contains below items:Ø P

38、roject BackgroundØ Summary of Basis of DesignØ System and Equipment DescriptionØ Single Line DiagramsØ Sequence of Operation and ControlØ Warranty Period Commissioning PlanJOHNSON CONTROLS has also reviewed the O&M Manual per the project requirements. The only comment to

39、 the O&M Manual is that the information provided should be more project specific, tagging the equipment specifically used on this project and crossing out the non-relevant items.10missioning PlanThere is a variety of signals that could generate the need formissioning systems.It is good practice

40、to continually optimize systems using data from the Building Automation Systems (BAS).In addition to tracking whole building energy use, monitoring specific system efficiencies for cooling, heating, and other energy consuming systems, can help detectpotential problems.When performance metrics indica

41、te potential problems, a partialversion of the original commissioning test should be conducted on the equipment in question, with focus on control sequence and components that relate to the problem. The building automation system has the potential to trend reported points, and this capability should

42、 be utilized when troubleshooting the system in question. If the trend feature is utilized this will provide valuable information that will assist operators and service technicians in troubleshooting. In addition to performing verification testing the equipment should receive preventative maintenanc
