The Basics of Benchmarking in ENERGY STAR® Portfolio Manager
U.S. Environmental Protection Agency (EPA) 2013
ENERGY STAR Commercial Buildings Program
• Offers a strategic approach to energy management
• Enables building owners, managers, and tenants to save money and protect the environment
• Provides organizations with measurable information on energy savings and greenhouse gas emissions reductions for commercial buildings
• ENERGY STAR on a building = superior energy performance
2
• The nation’s 17,450 K-12 school districts spend more than $8 billion annually on energy
• The least efficient schools use three times more energy than the best energy performers
• Top performing ENERGY STAR certified schools cost 40 cents per square foot less to operate than the average school
ENERGY STAR and K-12 − Over 6,100 ENERGY STAR certified K-
12 buildings − Over 1,150 K-12 ENERGY STAR
Partners − 85 percent of ENERGY STAR Leaders
are from the K-12 sector * Figures current as of September 2012
K-12 Statistics
Roadrunner Elementary School
• Located in Phoenix, AZ • Used behavioral changes and
retrofits to reduce energy consumption by 35.2 percent – Saved more than 338,000 kWh – Improved the building’s ENERGY
STAR energy performance score from 48 to 87 in three years
– Created an energy committee and an aggressive energy awareness campaign
4
Richardsville Elementary
• Bowling Green, KY • The first net-zero energy
school in the nation – Energy performance score of 100 – Geothermal system – On-site solar panels – Student Energy Team provides
energy savings tips and energy audits
5
• Assess Energy Performance
• Set Goals
• Implement Projects
• Document Savings
• Recognize Achievements
• Earn recognition
Strategic Approach to Energy Management
• Management Tool – Helps business and organizations by offering a platform to:
– Assess whole building energy and water consumption – Track changes in energy, water, greenhouse gas emissions, and cost over time – Track green power purchases – Share/report data with others – Create custom reports – Apply for ENERGY STAR certification
• Metrics Calculator – 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 15 building types)

Why Use Portfolio Manager? Understand Comparative Performance
• ALL buildings can be benchmarked • Benchmarking through Portfolio Manager enables
you to: – Compare one building against a national sample of
similar buildings – Compare all of your buildings of a similar type to each
other – Set priorities and targets for the use of limited staff time
and/or investment capital
8
ENERGY STAR Score • 1-to-100 scale identifies how a building is performing
relative to similar buildings nationwide
• Scoring models are derived from a statistically representative sample of the national building population
• Accounts for climate and operational characteristics specific to each building type—size, number of employees, weekly operating hours
• Score based on actual billed energy consumption not estimates or simulations
9
Required Information for Benchmarking in Portfolio Manager
• Building Identifiers – Name, street address, ZIP code for weather
normalization • Building and space type data
– Data specific to your building and space type • For offices: gross floor area, hours of operation, number of
workers on main shift, # of PCs, percent of gross floor area that is air conditioned / heated
• Energy use data – Building-specific invoice information from all
purchased energy of energy produced on-site (all fuel types)
– Begin with at least 12 recent consecutive months for each source and update with monthly usage data
10
Examples of Space Type Data • K-12 School
– Gross floor area – Whether the school is
open on weekends (yes/no)
– Whether the school is a high school (yes/ no)
– Number of personal computers
– Presence of cooking
facilities – Number of walk-in
refrigeration/freezer units
– Percent of the gross floor area that is heated
– Percent of the gross floor area that is cooled

Holmdel Township Public Schools Holmdel, New Jersey

Overview of District • The Holmdel Township School is comprised of four schools:
• Village School, Pre-K thru 3rd grade. 130,000 sq feet with 840 students
• Indian Hill School, Grades 4-5-6, 128,000 sq feet with 733 students
• W.R. Satz School, Grades 7–8, 93,000 sq feet with 505 students
• Holmdel High School, Grades 9-10-11-12, 201,000 sq ft with 1026 students.
• (For the purposes of utility tracking both the High School and WR Satz are considered one complex)
• Each of our schools received EPA ENERGY STAR recognition in 2011
• We began working with Energy Education, now know as Cenergistic, in January of 2009.
• With the guidance and expertise of Cenergistic, within the first year
into the program we were at 30% overall reduction in utility consumption.
• By the end of the 3rd year in the program we were over 50%
reduction in utility consumption saving on average $1,000,000 per year.
Program Overview
• Training began immediately with onsite support from Cenergistic Consultants followed by offsite conferences, seminars and phone support.
• Communication and leadership support is critical for success.
• Staff support and understanding of the program is instrumental.
• Behavioral changes are what drive the continued success. Hopefully they carry over to Energy Conservation at home.
• For every Therm and Kw reduction there is a financial savings.
• In addition to financial savings, there are environmental benefits with reduction in Greenhouse Gas emissions and reduction in Carbon Footprint.
Implementation
• Energy Manager is the eyes, ears and heart of program.
• Instrumental in tracking consumption and identifying areas of improvements.
• On-hand both during and after school hours to identify problems.
• Must be people person and able to communicate to everyone, from students to staff members, administrators and Board Members and also the community at large.
Energy Manager Role
• Financial impact of budget has been huge with over $3,000,000 saved over a 3-year time span.
• Environmental impact has also been a huge success with significant
reductions in Greenhouse Gas emissions and reduction in Carbon Footprint.
Impact
• Portfolio Manager made it easy to add our building information, current utility consumption and then calculate reductions from baseline.
• ENERGY STAR verification through Portfolio Manager was the
validation of the huge success of our program. • In 2011 we received ENERGY STAR Certification for Village School,
Indian Hill School and the High School/W.R. Satz Complex.
ENERGY STAR Participation
• Participation in ENERGY STAR and Portfolio Manager is critical to the success of any organization in reducing consumption of natural resources.
• Cenergistic lead us in the right direction while always providing support and guidance, none of which we could have received without their help and expertise.
