2 Report: Guidebook for Airports Provides Overview of Benefits of Whole Systems Lifecycle Approach to Retrocommissioning Provides Guidance for Planning and Executing Retrocommissioning Process

3 What is Retrocommissioning? A Systematic Process for Optimizing Existing Facilities through Identifying and Correcting Deficiencies Investigate Correct Validate Performance

4 ACRP Report 139 Appendix D Optimization for Airport Facilities Scoping Planning Investigation Implementation Verification

5 Project Scoping START: Identify General Focus Area Assess Feasibility/Limits Finalize Retrocommissioning Scope of Work Potential Considerations: Building Footprint Control System AHU/Pressure Zones Chronic repair issues Area Use Secure Passengers General Public Baggage Handling Potential Considerations: System configuration Number of AHUs Number of VAVs Space uses Building vintage Revise Scope as Necessary to Meet Budget/Time Constraints Request for Proposals and Budgeting Begin Planning Phase Project Scoping Planning Phase Investigation Phase Implementation Phase Verification Phase

6 Planning Phase Kick Off Meeting Facility Preliminary Inspection Project Scoping Document & Design Review Management & Maintenance Staff Interview Document Current Facility Requirements Develop Retrocommissioning Plan Operations Record Review Begin Investigation Phase Project Scoping Planning Phase Investigation Phase Implementation Phase Verification Phase

7 Investigation Phase Site Diagnostic Monitoring Test and Balance Systems Planning Phase Occupant Interviews System Test Procedure and Plan Development Detailed System Investigation & Testing Identify Opportunities To Optimize System Performance Implement minor repairs ( quick fixes ) to realize immediate improvements Systems Condition Assessment Document System Operations & Modifications Final Retrocommissionin g Investigation Report Begin Implementation Phase Project Scoping Planning Phase Investigation Phase Implementation Phase Verification Phase

8 Implementation Phase Commission New Capital Improvements Implement Cost- Effective Capital Improvements Review Capital Improvements Needed to Meet CFRs N o Investigation Phase Develop Implementation Plan Implement No- Cost and Low- Cost Improvements Adjustments sufficient to meet CFRs? Y es Update Training Materials & Conduct Training Develop or Update Systems Manual Implementation Phase Final Report Lessons Learned Meeting Begin Verification Phase Project Scoping Planning Phase Investigation Phase Implementation Phase Verification Phase

9 Verification Phase Verification Update Training Materials & Conduct Training Training Track + Evaluate 12-month Performance Identify and Correct Issues as needed Implementation Phase Verification or Ongoing Cx? Basic Ongoing Performance Evaluation Enhanced Restart Project Scoping Identify Tasks and Frequency for Ongoing Cx Assess Trend Data and Test Results Identify and Correct Issues as Needed Ongoing Commissioning
