Agenda n Benefits n Introduction to LEED Commissioning n Requirements and Deliverables n Process n Questions

Commissioning Purpose n 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? n Control System Problems n Comfort Problems n Air Quality Problems n Building Maintenance Costs n 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 Commissioning under Energy and Atmosphere

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

Fundamental Commissioning n 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 n The commissioning plan must contain: n n n 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? n Systems and Assemblies having to do with operational efficiencies: n n n HVAC Systems Building Automation Lighting Controls Domestic Heating Renewable Energy

Commissioning Specifications n Contract Divisions 1, 15 and 16

Installation Verification Focus is O&M

Master Deficiency List

Verify System Performance n Functional Testing of Systems: n n Observe Startup Activities Functionally Test Equipment and Systems

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

Enhanced Commissioning EA Credit 3 The Process Under LEED

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

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

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

Enhanced -Submittal Review Mechanical Equipment Submittal Documents for Completeness

Enhanced – Verify Training

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

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

Enhanced-Warranty Review Seasonal Testing Functional Tests for Summer vs. Winter Check Warranty Status and advise

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

Case Study n Community College Bldg. Classroom Laboratories n MEP Commissioning n Started Late in Construction Phase n Issues n Integrate Phoenix Fume with ALC controls n System Balance n Unoccupied Mode Operation n Success n teamwork n
