  1. Introduction toLEED Building Commissioning Presented by Bob Alpers, PE TESTMARCx Commissioning Solutions

  2. Agenda • Benefits • Introduction to LEED Commissioning • Requirements and Deliverables • Process • Questions

  3. Commissioning Purpose • How does the building function relative to the Owners Project Requirements?

  4. When should we start Commissioning? Benefits & Cost Savings Cost to Change $ Concept Design Construction Acceptance Occupancy Time

  5. What is systems are impacted most? • Control System Problems • Comfort Problems • Air Quality Problems • Building Maintenance Costs • Operations Staff understanding

  6. LEED Objective – Get Certified LEED Rating Points Required Certified 26-32 points Silver 33-38 points Gold 39-51 points Platinum 52-69 points Buildings Certified Under USGBC Guidelines

  7. LEED- EA Prerequisite 1 Commissioning under Energy and Atmosphere

  8. WHAT ARE THE LEED Commissioning ACTIVITIES? • Energy and Atmosphere Credit Category • EA Prerequisite 1 ( required, must be completed) • Fundamental Commissioning • EA Credit 3 ( additional available point) • Enhanced Commissioning

  9. Fundamental Commissioning • Pre-Requisite 1 Overview: • Designate a third party Cx • Review OPR and BOD Document • Specify Commissioning in CD

  10. Fundamental Commissioning Prerequisite Overview (Cont’d) • Develop a Cx Plan. • Verify installation meets BOD • Verify performance of systems • Summary report • Certify Commissioned

  11. Fundamental CommissioningEA Prereq. 1 The Process Under LEED

  12. Project Milestones in Construction Schedule Commissioning Plan Review Owners Functional Requirements & Basis of Design Verify Installation Pre-Functional Checklist Functional Testing Scoping Meetings Incorporate Commissioning Specification Collect Start-up Check sheets Final Cx Report PLAN DESIGN ACCEPT OCCUPANCY CONSTRUCT Project Timeline

  13. Owners Project Requirements Workshops Small groups to work out concepts

  14. Commissioning Plan • The commissioning plan must contain: • Overview & goals • Project information • Systems to be commissioned • Team’s roles & protocol • Describe Deliverables • List Key Milestones and schedule.

  15. What Systems does LEED require Commission? • Systems and Assemblies having to do with operational efficiencies: • HVAC Systems • Building Automation • Lighting Controls • Domestic Heating • Renewable Energy

  16. Commissioning Specifications • Contract Divisions 1, 15 and 16

  17. Installation Verification Focus is O&M

  18. Master Deficiency List

  19. Verify System Performance • Functional Testing of Systems: • Observe Startup Activities • Functionally Test Equipment and Systems

  20. Final Commissioning Report • Must be presented to the owner within reasonable time and must include: • Executive summary • Testing results • Deficiency List and History • Outstanding Issues • BOD review.

  21. Enhanced CommissioningEA Credit 3 The Process Under LEED

  22. Enhanced Cx • EA Credit 3 ( additional credit 1 point) • Design Review • Contractor Submittals Review • Verify Training • 10th Month Warranty & Operations Review • Systems manual

  23. Fundamental & Enhanced Commissioning Plan Cx Report and Systems Manual Owners Functional Requirements & Basis of Design Submittal & O&M Review Design Document Reviews & Commissioning In Specification Functional Performance Testing Warranty Review 10th month Operation Revised Plan Verify Installation & Checklist Scoping Meetings VerifyTraining Start-up PLAN DESIGN ACCEPT OCCUPANCY CONSTRUCT Project Timeline

  24. Enhanced – The Design Review Review Mechanical Systems Sequence of Control for Clarity

  25. Enhanced -Submittal Review Review Mechanical Equipment Submittal Documents for Completeness

  26. Enhanced – Verify Training

  27. Enhanced –Systems Manual Organizes the O&M Manual by Commissioned System All of Chilled Water Storage in one Section of Manual

  28. Enhanced -Verify Training • Training meets requirements: • Review Spec & • Verify meet Spec. • Include General Purpose of systems • Must include use of O&M Manuals • Must include operation all modes • Must be Qualified Trainers

  29. Enhanced-Warranty ReviewSeasonal Testing Functional Tests for Summer vs. Winter Check Warranty Status and advise

  30. Issues & Lessons Learned • General • Commissioning is Part of the Design Team • Contractors understand the commissioning TEAM’s Role • Energy Efficient Systems • Controls Become Complex and increase Risks • Technology is beyond Contractor Experience • Coordination of interposing systems is critical • Control Systems • Integration is coordinated • Schematic diagrams, Sequence of control and point lists are necessary • Details of BMS get input from owner • Owner Training • Video tape or not? • Meeting with Staff to discuss needs • Detailed Description in Spec of O&M needs. • Systems Manual training
