1 THE CRIME OF IMPROPER ENERGY MANAGEMENT COOLING MANAGEMENT SOLUTIONS Dan Mascola AGENDA Promote Background Cooling Management Solutions Case Studies Additional Energy Savings Tips How To Start on Monday CRIME OF ENERGY MANAGEMENT 3 1

2 PROMOTE PROMOTE Thanks electric company! CRIME OF ENERGY MANAGEMENT 5 PROMOTE CRIME OF ENERGY MANAGEMENT 6 2

3 PROMOTE Monthly newsletter or Daily facility energy use Greenhouse gas emissions...# of cars Active energy projects Tips tenants can do to reduce energy use Posters Quarterly events CRIME OF ENERGY MANAGEMENT 7 BACKGROUND PERSONAL BACKGROUND Product Marketing Manager at Vigilent Energy analysis Lighting, chillers, boilers, pumps, economizers, ventilation, process loads Building audits and walkthroughs Commercial, campus, labs, data centers, manufacturing, industrial Program management LEED, utility incentives, M&V, RCx, product development CRIME OF ENERGY MANAGEMENT 9 3

4 ABOUT VIGILENT Provides intelligent energy management systems for data centers, telco, central offices and buildings Intelligent control dynamic, predictive, adaptive Rapid deployment with minimal incursion Instant savings on energy costs Uniquely informed by Big Data, directed by Big Analytics CRIME OF ENERGY MANAGEMENT 10 COOLING MANAGEMENT WHY AM I HERE? To alert you to a great crime Culprit is lack of tools No visibility into energy operations Solving this particular crime is easy No research required Tools and technology are available to help manage environment and reduce energy CRIME OF ENERGY MANAGEMENT 12 4

5 EXPONENTIAL ENERGY GROWTH CRIME OF ENERGY MANAGEMENT 13 CHALLENGES 40% of utility bill is for heating and cooling Retrofit solutions expensive and disruptive Most buildings do not meet current codes Asbestos, occupant activities Technical issues Inefficient HVAC systems Unable to remotely monitor or manage Cannot diagnose or optimize AHU operations CRIME OF ENERGY MANAGEMENT 14 CHALLENGES Designing HVAC systems are difficult Everyone wants control Cool and heat at same time Loads change daily, seasonally Energy intense Buildings are dynamic environments Its always easy for tenants to complain CRIME OF ENERGY MANAGEMENT 15 5

6 ENERGY MANAGEMENT TODAY All on all the time Constant volume systems Cool everything down and reheat Static setpoints Large energy consumption No visibility into facility or HVAC system CRIME OF ENERGY MANAGEMENT 16 ENERGY MANAGEMENT REDEFINED Convert cooling/heating to a managed resource Data-rich view of building Identify faulty equipment Increase reliability and comfort Reduce energy costs CRIME OF ENERGY MANAGEMENT 17 INTELLIGENT COOLING CONTROL MEASURE Instrument the environment MODEL Profile the dynamic system Simulate effect of changes MANAGE Optimize closed-loop control Modify infrastructure CRIME OF ENERGY MANAGEMENT 18 6

7 ENERGY MANAGEMENT REDEFINED Monitor temperature with zone-level feedback Provide supervisory control for AHUs Convert constant air volume fans to variable volume Optimize temperature distribution CRIME OF ENERGY MANAGEMENT 19 COOLING CONTROL BENEFITS Typical: Outdoor air, return air, or damper based control Intelligent Cooling Control: - Distributed, zone-level sensing - Slow fans if zone temperatures are within limits - Limits are determined automatically and updated daily Benefits: - Self-configuring and self-maintaining - Improved thermal comfort management - Energy savings CRIME OF ENERGY MANAGEMENT 20 ADDITIONAL ENERGY SAVING TIPS 7

8 ACTIONS THAT SAVE ENERGY Turn off equipment that doesn t need to be running AHU scheduling Pumps Chillers Lights Occupancy sensors have 6 month 1 year payback CRIME OF ENERGY MANAGEMENT 22 ACTIONS THAT SAVE ENERGY Turn down equipment that doesn t need to be at 100% If you have VFDs, use them! Bi level lighting Pneumatic system compressors, what is the pressure setpoint? CRIME OF ENERGY MANAGEMENT 23 ACTIONS THAT SAVE ENERGY Replace inefficient equipment with efficient equipment Lights, lights, lights High efficiency motors, better payback for 24/7 operation Economizer functionality CRIME OF ENERGY MANAGEMENT 24 8

9 ACTIONS THAT SAVE ENERGY Adjust setpoints in BMS Fan static pressure Discharge air temperature Chilled water supply temperature Heating hot water supply temperature Economizer lockout setpoint CRIME OF ENERGY MANAGEMENT 25 HOW TO START WHAT TO DO NEXT MONDAY Measure energy from top down Facility Energy: electric bills, borrow monitoring equipment, ask utility for data End Use Energy: lighting, AHUs, chiller plant, boiler, plug loads Equipment Energy: Individual AHUs, chiller, pumps, cooling towers, lighting panels CRIME OF ENERGY MANAGEMENT 27 9

10 NEXT STEPS Graph to identify patterns vs CRIME OF ENERGY MANAGEMENT 28 NEXT STEPS Ask questions and point to areas for potential improvements Lets reduce AHU energy use during these hours when nobody is here Can we reduce our lighting loads? Why are we using heating energy in the summer? CRIME OF ENERGY MANAGEMENT 29 NEXT STEPS Find solutions to achieve goals Retrofit constant volume system with intelligent cooling control solutions Install occupancy sensors Adjust setpoints to minimize heating during the summer months Your utility is out to help, ask about incentive programs CRIME OF ENERGY MANAGEMENT 30 10

11 ACTONENERGY INCENTIVES Available cash incentives (based on annual energy savings) Electric Savings Lighting HVAC Gas Savings All $0.06/kWh $0.08/kWh $1.20/therm CRIME OF ENERGY MANAGEMENT 31 NEXT STEPS Don t forget to promote!
