A Few Words on ENERGY STAR
ENERGY STAR is a U.S.
Environmental Protection
Agency (EPA) voluntary
program that helps
businesses and individuals
save money and protect
our climate through
superior energy efficiency.

Energy Use in Water and Wastewater
Services
• Drinking water and wastewater services: – Account for 3-4 percent of national energy consumption
– Produce more than 45 million tons of greenhouse gas (GHG) emissions per year
• Drinking water and wastewater plants are typically the largest energy consumers of municipal governments, accounting for 30-40 percent of total energy consumed.
• Energy as a percent of operating costs for drinking water
systems can reach as high as 40 percent and is expected to increase 20 percent in the next 15 years due to population growth and tightening drinking water regulations.

Clean Energy Opportunity
• Studies estimate that 15-30 percent of potential savings
are “readily achievable” in water and wastewater plants.
These savings would provide:
– Financial returns in the thousands of dollars, and
– Payback periods of only a few months to a few years.
• Combining energy efficiency optimization/modifications,
energy recovery, and on-site clean power generation =
Zero Net (or Near Zero Net) Energy.
– Some wastewater plants generate as much energy as they use in a given year!

How Can Water and Wastewater
Utilities Get Involved Now?
• Get started with ENERGY STAR. Whether you're new to
energy management or ready to take your program to the
next level, EPA’s ENERGY STAR program can help you
accomplish your goals.
• Utilize ENERGY STAR resources to: – Build an energy program
– Improve energy performance
– Benchmark energy use
– Communicate and educate
• Visit http://www.energystar.gov/buildings to start
improving energy performance today.
13
A Strategic Approach
to Energy Management
14
This approach is based
on the successful
energy management
practices of thousands
of commercial and
industrial organizations.
Benchmarking
A benchmark is a point of reference from which to make comparisons.
15
The Value of Benchmarking
Consistent
benchmarking in
buildings results in
energy savings and
improved performance.

• ENERGY STAR Portfolio Manager is an effective management tool – it helps business and organizations by offering a platform to:
– Assess whole property energy and water consumption
– Track changes in energy, water, greenhouse gas emissions, and cost over time
– Track green power purchase
– Share/report data with others
– Create custom reports
www.energystar.gov/benchmark
18
• Portfolio Manager is also a metrics calculator – it provides key performance metrics to integrate into a strategic management plan.
– Energy consumption (source, site, weather normalized)
– Water consumption (indoor, outdoor)
– Greenhouse gas emissions (indirect, direct, total, avoided)
– ENERGY STAR 1-to-100 score (available for many building types and wastewater treatment plants)
– Compare to national median energy use intensity (site, source)
– Compare baseline year vs. current year (energy, water, ghg)

Benchmarking Wastewater
Treatment Plants
19
• ENERGY STAR 1 – 100 score available – Based on Water Research Foundation survey
– Accounts for sources of energy used, geography/ weather
• Data Needed: – Energy use for all fuels - monthly
– Average Daily Influent Flow (million gal/day – MGD)
– Average Influent Biochemical Oxygen Demand (BOD) Concentration - average over 12 months (mg/l)
– Average Effluent BOD Concentration - average over 12 months (mg/l)
– Plant Design Flow Rate - treatment design (MGD)
– Trickle Filtration Process (yes/no)
– Nutrient Removal (yes/no)

What Does it Do?
1. How much new energy efficiency equipment can be purchased from the anticipated savings?
2. Should this equipment purchase be financed now or is it better to wait and use cash from a future budget? (avoid paying interest)
3. Is money being lost by waiting for a lower interest rate?
