1 Risk Management What do I want on my SATs?

2 Why are there SAT s? College Board 1901-purpose eliminate bias 1926: Became Scholastic Aptitude Test 1930: arithmetic added then subtracted in : math back in 1990: name-scholastic Assessment Test 1994: name change to SAT 2005: writing section added 2007: some want to abolish

3 What do they guarantee? Stanford, MIT, UofA? Football? Julliard? readin, ritin, rithmatic

4 Why is there Commissioning? Hard Facts about Soft Costs Construction Productivity Improved Technology Advanced Significantly Fees Based on Outdated Metrics (% or $/S.F) Reduced # Professional Hours on Project Commissioning Program Drivers Unhappy Owners Demand Side Management Leadership Energy & Environmental Design

5 Why is Commissioning in LEED? Greenwash (Wikipedia) 99% of 1,018 Products Sinned (TerraChoice( TerraChoice) Six Sins of Greenwash Hidden Tradeoff (efficient mercury) No Proof (26% trust me ) Vagueness (never mind the arsenic) Irrelevance (no PCB s so so what) Lesser of Two Evils Fibbing

6 Where is Commissioning in LEED? Sustainable Sites (8 credits/14 points) Water Efficiency (3 credits/5 points) Energy & Atmosphere (6 credits/17 points) Materials and Resources (7 credits/13 points) Indoor Environment Quality (8 credits/15 points) Innovation and Design (2 credits/5 points) Total Available (34 credits/69 points)

7 How does LEED Commission? Credit Prerequisite 1: Fundamental Cx of Energy Systems Prerequisite 2: Minimum Energy Performance Prerequisite 3: Fundamental Refrigerant Mgt. Points Required Required Required Credit 1: Optimize Energy Performance Credit 2: On-Site Renewable Energy 1-3 Credit 3: Enhanced Commissioning 1 Credit 4: Enhanced Refrigerant Management 1 Credit 5: Measurement and Verification 1 Credit 6: Green Power 1 Total Points Available 17

Cx manuals are turned over to the Owner. FIGURE #3 - COMMISSIONING DATA MANAGEMENT FLOW CHART

11 Managing Problems (Issues) Issue Identification Issue Types: Level 1 Test can not proceed until resolved Level 2 Portions of test can not be checked Level 3 Does not prevent testing (Punch list) Track & Manage on web-based based data system Don t t make more problems than you solve. Things may not be a big as you think.

12 Prepare for the Unexpected Procedure to update test Test Version control is crucial Changes must occur well in advance of test Procedure to handle deviations during test Scope modifications Add unexpected tests Audit contractor quality control Oversee third party testing Document control items not commissioned
