18. Plant Commisioning Discussion

19. Plant Commissioning Discussion • How will Trane provide ongoing operational support? • Trane will provide: • Startup Orientation and System training • Continuous Commissioning Support • Remote Monitoring and Reporting • Intelligent Dispatching • Site Visits • Continuous dialog concerning system operating improvements

20. Startup Orientation and System Training • Trane Contracting personnel in conjunction with Trane Service personnel will provide Brethren Village personnel with onsite orientation and training of the Central Plant operational requirements, as well as all aspects of the larger control system • These “turnovers” and training events will occur as each system is brought on-line

21. Continuous Commissioning Support • The Trane Commissioning Team will establish system baseline performance data and ensure system performance thru monitoring and adjustments as required • Thru the use of Trane Centralized Remote Monitoring and monthly comparisons to baseline data, Trane will ensure that we meet the Owners Project Requirements • Due to the phased nature of this project, commissioning will be ongoing thru project completion and the baseline criteria will evolve

22. Remote Monitoring and Reporting • Trane's Centralized Monitoring center located in Columbus Ohio is staffed by Trane Operations Managers and BAS Service Technicians • The TCM is supplied with system component information, systems data points and monitoring requirements • Data is collected 24 hours a day, 7 days a week, 365 days a year. Deviations from baseline system performance are identified and corrective action recommendations are made and or performed • Reports are generated monthly showing key operational metrics

23. Intelligent Dispatching • Though outside of the specification, our proposal includes TCM intelligent dispatching, wherein our Remote monitoring staff will: • Receive critical system alarms • Remotely verify alarms • Remotely diagnose problems • Contact designated Brethren staff or Trane Service personnel as directed • Provide recommendations for corrective action • Coordinate local office Trane Service Technician dispatch as required by warranty, or as requested by Brethren Village

24. Site visits • Site visits are performed by seasoned Trane Technicians to ensure the Central Plant systems are operated and maintained to achieve maximum system performance • Frequency of visits will be dependant on system operation, sub-system commissioning and project requirements. We expect the following: • Monthly site visits during plant operation through December, 2011 • Transition visits as buildings come on line • Seasonal visits to confirm proper control transition (Spring/Fall)

25. Additional Value added Services • Not included in this quotation, but within Trane’s capabilities as additional value added services: • Equipment Service Agreements • Controls Service Agreements • Water Treatment Service Agreements • Predictive Testing services such as Eddy Current Testing and Vibration Analysis • Additional Energy Services Software and reports
