  1. 1. Energy Management Solutions that Reduce CostsWednesday, June 9th, 2010 Presented by: Janie Jefferies-Freer VP Sales, eSight Energy Group Hosted By: Building Engines
  2. 2. Agenda 1. Introduction 2. Challenges in implementing an Energy Management System (EMS) 3. Components of an EMS 4. Techniques for energy reduction 5. Demonstrable ROI 6. Client case studies 6.9.10: Energy Management Solutions That Reduce Costs
  3. 3. Janie Jefferies-Freer eSight Energy, Inc. www.eightenergy.comProcess & Industrial Health Care Government Retail Property Management Education
  4. 4. IntroductionQ: What is Energy Management?A continuous planning process that drives the efficient use of energyin a building or processQ: What does it mean today?A focus on cost reduction and conformance to emerging bestpractices and legislation 6.9.10: Energy Management Solutions That Reduce Costs
  5. 5. Chapter 1Challenges in Implementing and Energy Management System (EMS) If you can’t measure it, you can’t manage it. • Organizations look towards energy reductions to achieve cost savings • Driven by energy costs, legislation or desire for corporate social responsibility • Energy Management System (EMS) ensures visibility. Otherwise, data is low frequency, manually input, unreliable • It can be seen as extremely expensive or complicated to implement an EMS project • Where to start?? 6.9.10: Energy Management Solutions That Reduce Costs
  6. 6. Chapter 1Challenges in Implementing and Energy Management System (EMS) Major Challenges: • Multiple sites with data in disparate systems • Multiple data sources (occupancy, temperature, production) • Limits on energy/utility types that can be measured • Diverse, incompatible protocols • Limited data access/manipulation •Concern over project cost and ROI 6.9.10: Energy Management Solutions That Reduce Costs
  7. 7. Chapter 1Challenges in Implementing and Energy Management System (EMS)Getting Started: Keep it Simple Actual vs. metered usage Determine infrastructure: • BAS, meters, submeters • Supplier data • Disparate data sources 6.9.10: Energy Management Solutions That Reduce Costs
  8. 8. Chapter 1Challenges in Implementing and Energy Management System (EMS)Getting Started: Keep it Simple Phased approach: 1. Implement formal energy policy 2. Seek outside help 3. Determine budget vs. payback - How much is it worth to you? - Determine what you need 6.9.10: Energy Management Solutions That Reduce Costs
  9. 9. Chapter 2Components of an Energy Management System (EMS) What Steps to Take? 1. Identify 2. Analyze 3. Quantify 4. ReduceInstalling an energy management system (EMS)should be the first step towards reducing energy 6.9.10: Energy Management Solutions That Reduce Costs
  10. 10. Chapter 2Components of an Energy Management System (EMS) Energy Management Components Metering/Energy Data • Metering (main meters / secondary meters) • Building Automation System • Utility bills • Manual meter readings Automatic Data Collection • Log data every 5/15/30 minutes • Communicate readings to a PC or server Energy Management Software (EMS) • Concise analysis of energy data • Targeted techniques for finding savings • Energy alarms and reporting 6.9.10: Energy Management Solutions That Reduce Costs
  11. 11. Chapter 2 Components of an Energy Management System (EMS) DC From Office Staff Centralized energy Loggers, BA management system S etc Management End Users Consultants Utilize methods to gather disparate Central Energy data into a single, centralized Management team or FM database. Not just energy data, but company, Operations, ‘peripheral’ data Maintenance , Consultants Data distributed out Data collected from on a need-to-knowmultiple locations (sites, basis by department orbuildings, departments) meter / user etc potentially worldwide 6.9.10: Energy Management Solutions That Reduce Costs
  12. 12. Chapter 2Components of an Energy Management System (EMS) THE PROCESS OF ENERGY MANAGEMENT Identify Data Exception Energy Optimization Collection Reporting Usage 6.9.10: Energy Management Solutions That Reduce Costs
  13. 13. Chapter 2Components of an Energy Management System (EMS)DATA COLLECTION Data Identify Optimize Report Electricity Degree Day or Gas localized Water air temperature values Steam Compressed Air Production Values Oil Building Occupancy Financial (utility bills, utility tariffs) 6.9.10: Energy Management Solutions That Reduce Costs
  14. 14. Chapter 2Components of an Energy Management System (EMS) IDENTIFY ENERGY USAGE Data Identify Optimize Report By bringing together all factors affecting energy usage, you gain:• Holistic view of energy usage and driving factors behind it (temperature, occupancy, ft2, production values etc)• Ability to normalize depending on variances (temperature, occupancy, ft2 ,production values etc. )• Ability to reconcile costs and perform very accurate cost analysis• Understanding of total usage and how it breaks down across siteEssential to be able to monitor data from all utilities/factors that affect usage 6.9.10: Energy Management Solutions That Reduce Costs
  15. 15. Chapter 2Components of an Energy Management System (EMS) OPTIMIZATION Data Identify Optimize ReportAn EMS incorporates many targeted techniques for accurate data analysis• Techniques are ‘over and above’ those utilized within property BAS• Time saving – eliminates manual ‘number crunching’• Ability to view high level usage with drill-down to equipment level• Optimizes equipment operation (e.g. HVAC, lighting) to reduce overall energy usage• Automatically highlights problem areas (e.g. changes in control equipment settings)• Automatic notifications based on site/user/timeframe etc. (baseload, set points, cost analysis, load balancing, peak demand etc all reported automatically) 6.9.10: Energy Management Solutions That Reduce Costs
  16. 16. Chapter 2Components of an Energy Management System (EMS) REPORT Access to energy data via Data Identify Optimize Report dashboards for END USERS Internet / Network access to EMS by trained users EMS Server – Internet / Corporate Network Energy Cost Normalization Emissions Alarm Tenant Reporting Analysis Analysis & Target Setting Management Handling Billing EMS Building Integration Energy usage, temperature, occupancy, production values, ft2, cost data etc
  17. 17. Chapter 2Components of an Energy Management System (EMS) Dynamic dashboards can present data in an informative and user friendly way, suitable for any ability level
  18. 18. REGRESSION – ENERGY EFFICIENCYRegression analysis can be used to compare energy consumption against adriving factor such as temperature, hotel guests, production volumes.

  21. 21. Base loadIdentifyInitial analysis of electricity use onthe wards highlighted a higher thanexpected base load.ProjectTen energy champions wereidentified and a project initiated tocheck and reset timers back tocorrect values.
  22. 22. How do you save real $$s?Understand the characteristics of your site• Different techniques for different sectors• Performance analysis, benchmarking sites• Normalization of data• Verification of utility billing informationLook at top level data to identify anomaliesAnalyze data using targeted techniques togenerate actionable intelligence (rather then just‘number crunch’)
  23. 23. BENEFITS OF AN EMS• Save 5-20% in energy usage• Significantly reduce costs with powerful techniquestargeted towards specific areas of usage• Brings together energy data into a single, centralizeddatabase - doing this gives you an holistic view of whatis occurring• Automated exception alerts• Validate utility bills against internal data• Engage staff by sharing information via dashboards
