Energy Management

for Dummies

Reduced Emissions

Positive Cash Flow

A Sustainable Activity

Dick Pearson, P.E., ASHRAE Fellow


Renewables as anEnvironmental Solution?


Where Do We Use Energy?


Energy Management is the Quickest, Cheapest, Cleanest Way to Extend World Energy Supplies

Energy management can provide 2.5 times

the environmental impact of renewable energy


Global CO2 Levels Exceed 400 ppm


Energy Management 101 – Example

  • Management commitment

  • Manual daily meter reading

  • Operational changes only

10


Energy Management 101The Building

20-Story Office Building:

  • 200,000 ft2

  • 5 years old, no energy conservation

  • Complex, energy intensive HVAC systems

  • High utility bills

  • No building automation system

11


Energy Management 101How It Worked

Actions by Facility Manager:

  • Reviewed operations ideas with building engineer and design engineer

  • Reviewed daily meter data for impact, intuitively adjusting for weather

  • Harassed/complimented building engineer daily on performance

12


Energy Management 101How It Worked

  • Actions by Building Engineer

  • Aligned building schedules with occupancy times

  • Raised cold deck temperature

  • Lowered hot deck temperature

  • Outside air was introduced only during occupied hours

  • Reduced duct pressures

Savings in one year: 33%!

ENERGY STAR Guidelines

describe a management cycle that helps you with Execution—getting things done!

Benchmarking Using

ENERGY STARwww.energystar.gov/benchmark

15


Comparative Metrics:

The Heart of Benchmarking

Is 60 MPG high or low for this automobile?

Is 90 kBtu/SF/YR high or low for this building?

Fuel Efficiency: MPG

Energy Performance Rating: 1 to 100


Houses of Worship

K-12 Schools

Office Buildings

Banks/Financial Institutions

Dormitories

Medical Offices

Hospitals

Retail Stores

Warehouses

Hotels

Wastewater Treatment Plants

Data Centers

Supermarkets

Courthouses

ENERGY STAR Score

Eligible Building Types

Senior Care Facility


Energy Star Portfolio Manager


Two Types of Action

  • Smarter use of what you have right now (Discretionary Operation)

  • Energy Audits and Capital Improvements


Disincentives for the Building Engineer

  • Risk of occupant discomfort

  • Risk of equipment failure

  • Experimentation can be terrifying


Incentives for the Building Engineer

  • Regular monitoring by the manager

  • Managerial encouragement to experiment

    • Occasional, brief discomfort is OK

  • Teamwork

  • Accomplishment – Getting results


Examples of Success

Aurora Health Care Equivalent Revenue Using a 4% margin

  • 2009 – 2012 Total Energy Savings (weather-normalized)

  • Total Savings = $8,665,000

  • $8,665,000 ÷ 0.04 (margin) =

  • $216,625,000 equivalent revenue

  • $216,625,000 ÷ 4 years =

  • $54,156,250 equivalent revenue per year
