What is ENERGY STAR?

• ENERGY STAR is a voluntary program that
  identifies links between energy, financial, and
  environmental performance.
• ENERGY STAR reduces greenhouse gas emissions by
  making it easy for institutions and consumers to
  improve energy efficiency.
• ENERGY STAR is the symbol for superior energy
  performance.

3
What have ENERGY STAR Partners Accomplished?

• Thousands of organizations have partnered with
  ENERGY STAR .
• In total, partners have reduced carbon dixoide
  emissions by over 1.2 trillion pounds, with
  cumulative energy bill savings of 60 billion
  through 2010. This is equivalent to
• 164 million acres of new trees planted
• 120 million cars taken off the road
• Annual electricity needs of over 80 million
  homes.

The Value of Benchmarking Energy Performance

• Benchmarking energy performance allows you to
  
• Establish a baseline to understand where you
• are now
• Compare your buildings performance across
• your company and nationally
• Create a roadmap for improvement
• Track and measure improvement and reward
• success

11
Performance Rating System

• City Lizard Lick, NC
• Buildings 40
• Costs 1.40 - 1.80 per sq. ft.
• How do you rate this performance?
• Benchmarking lends a national perspective
• Scores 40 - 80
• 80 excellent, eligible for ENERGY STAR label
• 40 good potential to lower costs, energy usage,
  and air pollution

Performance Rating System

• Comprehensive support to improve building
  energy efficiency
• Receive recognition
• Obtain national perspective
• Incorporate into energy management practices
• Set goals for upgrade work
• Use results to obtain funds
• Communicate your success

29
Benchmarking New Building Design

• 1. Use design specification of building that
  enables hr-by-hr simulation to obtain monthly
  annual energy usage.
• 2. Obtain monthly energy usage for all sources
  (e.g., kWh, ccf).
• 3. Use this in benchmarking tool and obtain score.

30
Benchmarking New Building Design

• 4A. If score lt 85, or building can be specified
  more completely, refine design and/or revise to
  improve energy efficiency and return to 1.
• 4B. If score /gt85 with building specified as
  fully as possible, then work with benchmarking
  tool is complete. Have confidence in forecast.
