Phoenix Convention Center Phoenix, Arizona Getting Results From Your Energy Projects Session 3Greening the Federal Government Jim Bochat Commissioning Concepts, Phoenix AZ [August 11, 2015]

Energy Exchange : Federal Sustainability for the Next Decade HOW DO YOU MEET YOUR ENERGY & WATER MANDATES Energy Reduction EO and EO – 3% per Year Total 30% Water Reduction EO – 2% per Year Total 36% (16% 2015) ARE YOU THERE YET? 2

Energy Exchange : Federal Sustainability for the Next Decade HOW DO YOU GET THERE? Energy – Energy Audit – Retro Commissioning & Optimization – Metering – Lighting Reduction and Upgrades – Reduce Hot Water use – System Upgrades and Replacement – Renewable Energy Site Generated 3

Energy Exchange : Federal Sustainability for the Next Decade HOW DO YOU GET THERE? Water – Water Audit – Metering – Low Flow Plumbing Fixtures – Eliminate Water Leaks – Reduce Landscape Water Use – Increase Cooling Tower Cycles of Concentration – Reduce Water Pressure 4

Energy Exchange : Federal Sustainability for the Next Decade PROCUREMENT If Reduction is really what you want, why are you not getting it from what you purchase? – Definitions are not standard Energy Audit Level 1, Level 2? Retro Commissioning & Optimization Two Points of View Yours and Theirs – Specify Outcomes Do Not Specify Standards, Specify Results Do Not Specify Measures, Specify Results 5

Energy Exchange : Federal Sustainability for the Next Decade GETTING RESULTS Energy & Water Audits – Should only need one – Ask for a root cause analysis for each recommendation – Ask for a written detailed scope of work for each recommendation – Require detailed energy or water savings calculations for each issue recommended – Act immediately on the low cost / no cost recommendations 6

Energy Exchange : Federal Sustainability for the Next Decade GETTING RESULTS Retro Commissioning – Require quick fixes be performed as a part of the RCx project – Require as Found air and water flow readings – Require 100% verification of terminal unit calibration – Require control system testing – Require system optimization – Outcome = Building works better after the RCx than before, not just recommendations 7

Energy Exchange : Federal Sustainability for the Next Decade STAY ENGAGED IN THE EFFORT Participate or Observe the Energy Audit or RCx efforts – Ask Questions – Make sure root causes are identified – Don’t accept the report if it does not deliver what you want 8

Energy Exchange : Federal Sustainability for the Next Decade STAY ENGAGED IN THE EFFORT Utilize a Performance Verification (PV)Process – Track Power, Gas, and Water usage on a monthly basis – Evaluate projected trend lines – Make operational changes to improve performance – Perform next month cycle of PV system – Publish Results 9

Energy Exchange : Federal Sustainability for the Next Decade PUBLISH PERFORMANCE 10 ASHRAE PMP Best Practice Guide PV System

Energy Exchange : Federal Sustainability for the Next Decade PERFORMANCE VERIFICATION SYSTEM 11

Energy Exchange : Federal Sustainability for the Next Decade Energy & Water Reduction Reducing Energy and Water Use is a people problem not a technical problem – A 10% reduction can be achieved by just paying attention Engage Management, Operators and Occupants Praise Positive Results 12
