Introduction to LEED Building Commissioning Presented by Bob Alpers, PE TESTMARCx Commissioning Solutions Agenda Benefits Introduction to LEED Commissioning Requirements and Deliverables Process Questions Commissioning Purpose How does the building function relative to the Owners Project Requirements? When should we start Commissioning? Benefits & Cost Savings Cost to Change $ Concept Design Construction Time Acceptance Occupancy What is systems are impacted most? Control System Problems Comfort Problems Air Quality Problems Building Maintenance Costs Operations Staff understanding 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 LEED- EA Prerequisite 1 Indoor Environmental Quality Sustainable 23% Sites 22% Materials & Resources Water 20% Efficiency Energy & Atmosphere Commissioning under Energy and Atmosphere 27% 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 Fundamental Commissioning Pre-Requisite 1 Overview: 1. Designate a third party Cx 2. Review OPR and BOD Document 3. Specify Commissioning in CD Fundamental Commissioning Prerequisite Overview (Cont’d) 4. Develop a Cx Plan. 5. Verify installation meets BOD 6. Verify performance of systems 7. Summary report 8. Certify Commissioned Fundamental Commissioning EA Prereq. 1 The Process Under LEED Project Milestones in Construction Schedule Commissioning Plan Verify Installation Pre-Functional Checklist & Basis of Scoping Design Incorporate Meetings Collect Commissioning Start-up Specification Check sheets Review Owners Functional Requirements PLAN DESIGN Project Timeline CONSTRUCT Functional Testing ACCEPT Final Cx Report OCCUPANCY Owners Project Requirements Workshops Small groups to work out concepts 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. 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 Commissioning Specifications Contract Divisions 1, 15 and 16 Installation Verification Focus is O&M Master Deficiency List Master Deficiency List (latest deficiencies in bold text) Date February 3, 2005 Item # EQUIP # /Spec Section 1 Panel HCR2 2 Panel LCR2 DATE FIV/ FPT/O&M REVIEWED 8/9/2004 8/9/2004 DEFICIENCY RESP. FIV The electrical working clearance for Panel HCR2 is not per NEC 110. Panel LCR2 blocks the right portion of the panel width within the 42" reqmt. CEC FIV The electrical working clearance for Panel LCR2 is not per NEC 110. The conduits at the floor in front of the panel, penetrate the floor in front of the plane of the panel can. CEC CEC ACTION TAKEN DATE Cx VERIFIED 3 Panel HN3 8/9/2004 FIV The electrical working clearance for Panel HN3 may not be per NEC 110. The transformer and flexible conduits @ the floor must be 42" from the panel (exposed live parts). 4 Panel LCR5 8/9/2004 FIV The electrical working clearance for Panel LCR5 is not per NEC 110. The adjacent panel can blocks the right portion of the panel width within the 36" reqmt. CEC 5 AHU 1 8/9/2004 FIV The chilled water coil pull is blocked by the header at the coil. B&K Flanged connections have been provided in the piping above the coil for piping removal for coil pull. JAH 9/20/04 6 RF 5A 8/9/2004 FIV The relief duct is tapped into the back of the 90 degree silencer. B&K PCA Relief duct tap into 90o silencer approved and designed by M&I Systems. JAH 9/20/04 FIV The FSDs at the floor entering the return (see sheet M406) are not accessible without dismantling a section of the fabricated return plenum. An access door is not shown to be installed. B&K PCA Removable access panels have been provided in the return plenum for access to FSDs. JAH 9/20/04 7 RF 5A and B 8/9/2004 Verify System Performance Functional Testing of Systems: Observe Startup Activities Functionally Test Equipment and Systems 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.
