ENERGY STAR® is the national symbol
for protecting the environment through
energy efficiency.
DESIGN TO EARN THE ENERGY STAR
Architecture firms can now distinguish building designs that are among the most energy efficient
in the country as "Designed to Earn the ENERGY STAR." Building design projects can receive an
energy performance rating from EPA's easy-to-use tool Target Finder. Setting an energy goal,
rating energy performance, and being recognized for a design project that's well done can all be
achieved through ENERGY STAR.
SETTING PERFORMANCE TARGETS
Do you know, early in the design process, what the energy use target should be for a high
performance building?
Now there's an easy way to get an energy use target that's tailored to your specific design project.
Target Finder provides a realistic energy consumption target for the building design, which is
derived from existing commercial building data. It lets you choose a target rating and provides the
associated energy use and costs, as well as an energy use target for the top 10% of U.S. buildings.
Keith Giamportone, AlA-Brown, Jurkowski Architecture Collaborative says, "It [Target Finder]
gives quick feedback on energy use targets ... . I have wanted some 'rules of thumb' or a
'framework' to help the entire design team set an energy use goal early in the design process
and this is exactly what I need."
RATING DESIGN PERFORMANCE
When clients ask for an ENERGY STAR or "high
performance building," do you know if the design
achieves their goals?
It has been difficult to know if the estimated energy
use for a building design is comparable to similar
high performing buildings. Building designs that
meet or exceed energy codes as a measure of high
performance may not include a complete energy
use profile. Nor do you know if the intended energy
use ranks among the best in the nation. Now with
Target Finder you can receive a 1-100 rating for the
design, once the total annual energy use has been
calculated (Figure 1). This is a critical step in
knowing whether your design ranks among the
best for energy efficiency.
ACHIEVING THE BEST
Are your buildings designed to be ENERGY STAR?
If the design's rating is 75 or higher, the Architect of Record can display the "Designed to Earn
the ENERGY STAR" graphic on building plans and documents. EPA's ENERGY STAR recognizes
both architects and building owners for their commitment to delivering high performance
buildings that protect the environment.

EPA Energy Performance Rating
Figure 1. EPA's energy performance rating uses
a 1-100 scale. Lower energy use yields a higher
performance rating. A 75 or higher design rating
achieves ENERGY STAR.
If it isn't energy efficient... it's not sustainable.

SET GOALS AND RATE YOUR DESIGN
Target Finder, EPA's rating tool, can be used throughout the design process to help translate design intent into
superior operational performance. The rating applies the same performance metric from pre-design through
schematic design development and during
building operation to determine how the
energy use ranks against similar buildings
across the nation.
TARGET FINDER
To use Target Finder, all required fields must
be completed.
Pre-Design: Set Energy Goal
1. FACILITY INFORMATION
Use zip code of project location (required
to calculate energy use target).
2. FACILITY CHARACTERISTICS
Space types: Office, K-12 School, Hospital,
Hotel, Medical Office, Residence Hall,
Supermarket, Warehouse.
3. TARGET RATING
Select a "Target Rating" from 50 to 100,
and the tool provides the estimated total
annual energy use and cost. A 75 or
higher rating is ENERGY STAR.
Select "View Results" and see
next page.
Schematic Design Development:
As the design develops, enter results
from energy analysis calculations to
get the Design Rating.
4. DESIGN ENERGY
Enter energy data: source, units, annual
usage, and rate.
Select "View Results" and see next page.
Note: An incomplete energy use profile
could result in a high but inaccurate rating.
Total annual estimated energy use must
include plug, process, and all non-regulated
loads; equipment loads specified on
drawings; and all fuel sources.*

*The EPA energy performance rating used in Target Finder is derived from fuel consumption data of existing commercial buildings, which includes the tota
energy use associated with the building. Therefore, design energy use must include all fuel sources and total estimated energy use for the building design
Gaps in energy analysis must be addressed in order for the rating to be a useful indicator of future performance.

RESULTS
In the example results table (left),
a 50,000 sq. ft. building design
with a 60 rating is estimated to
cost an additional $17,976
annually than one with an 80
rating. The anticipated energy
cost savings could be used to
invest in more aggressive energy
efficiency measures.

The data used for the energy performance rating are derived from the U.S. Department of Energy's Commercial Building Energy Consumption Survey.
The required data inputs for the rating were found to be the primary drivers of energy use—building size, geographic location (climate), occupancy, and
plug load.
