4. Introduction
Q: What is Energy Management?
A continuous planning process that drives the efficient use of energy
in a building or process
Q: What does it mean today?
A focus on cost reduction and conformance to emerging best
practices and legislation

5. Chapter 1
Challenges 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. Chapter 1
Challenges 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

7. Chapter 1
Challenges 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

8. Chapter 1
Challenges 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

9. Chapter 2
Components of an Energy Management System (EMS)
What Steps to Take?
1. Identify
2. Analyze
3. Quantify
4. Reduce
Installing an energy management system (EMS)
should be the first step towards reducing energy

10. Chapter 2
Components 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

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-know
multiple locations (sites,
basis by department or
buildings, departments)
meter / user etc
potentially worldwide

14. Chapter 2
Components 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 site
Essential to be able to monitor data from all utilities/factors that affect usage

OPTIMIZATION Data Identify Optimize Report
An 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)

Dynamic dashboards can present data in
an informative and user friendly
way, suitable for any ability level

18. REGRESSION – ENERGY EFFICIENCY
Regression analysis can be used to compare energy consumption against a
driving factor such as temperature, hotel guests, production volumes. Drift

22. Base load
Identify
Initial analysis of electricity use on
the wards highlighted a higher than
expected base load.
Project
Ten energy champions were
identified and a project initiated to
check and reset timers back to
correct values.

28. 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 information
Look at top level data to identify anomalies
Analyze data using targeted techniques to
generate actionable intelligence (rather then just
‘number crunch’)

29. BENEFITS OF AN EMS
• Save 5-20% in energy usage
• Significantly reduce costs with powerful techniques
targeted towards specific areas of usage
• Brings together energy data into a single, centralized
database - doing this gives you an holistic view of what
is occurring
• Automated exception alerts
• Validate utility bills against internal data
• Engage staff by sharing information via dashboards
