Initiative Purpose
Challenge U.S. manufacturers to build and deliver innovative,
competitively priced, energy-saving rooftop units that meet the
Commercial Building Energy Alliance (CBEA)-driven requirements
of a high-performance specification
Realize large energy and cost savings for CBEA members and for
the nation

Drivers
• DOE wants to reduce energy use in commercial buildings
• Owners want to save energy and money
• Manufacturers want to develop and sell better equipment
Background
Fact: Packaged (unitary)
equipment uses > 50%

• An estimated 40,000 Ten Ton RTUs sold per year
• A 100,000 sq. ft. large box retail building contains
20 Ten Ton RTUs
• Units being purchased today aren’t “best in class”
• Best in class has…
– ARI rated efficiency from the baseline 11.0 EER / 11.2 IEER to 18
IEER
– Decrease air flow by specifying variable air volume rather than
constant air volume
– Increase fan efficiency from 45% efficient to premium efficiency
Enabling Market Innovations
If companies only buy best in class Ten Ton RTUs, they
- decrease energy needs by 50%
- save about $50 million a year in energy costs
- mitigate the need for 5 power plants

Primary features of specification:
Guide for manufacturer’s development of RTU
High performance requirement (18 IEER) addresses
part-load operation
Performance testing
Direct Digital Control based unit control system
Diagnostics and wireless communication (to sustain high
level of performance throughout equipment lifetime)
Key Elements of Specification

As CBEA offers challenge to RTU manufacturers, DOE will
offer technical assistance to manufacturers to help meet the
performance specification. DOE will offer lab competencies
including those in:
– HVAC Technology Development and Design
– Testing and evaluating
– Fault detection and diagnostics
– Diagnostics and commissioning
– Controls and Communications
– Energy Simulations

Letter of Support
This announcement demonstrates support of the undersigned companies for
the High-Performance Rooftop Air-Conditioning Specification developed with
technical assistance by the U.S. Department of Energy (DOE).
These companies are members of DOE’s Commercial Building Energy
Alliances (CBEAs), managed by key industry partners, and whose goal is
cost-effective energy-efficiency investments. We are honored to introduce
this specification for High-Performance Rooftop Air-Conditioners to challenge
U.S. manufacturers to build and deliver innovative, energy-saving products.
We will strongly consider purchasing units that meet the specification, are
consistent with our cost-effectiveness criteria, and align with our procurement
time frames. We look forward to working with the manufacturers and DOE
to factory witness tests of prototype units that meet this specification. We
understand that DOE has committed resources and technical assistance
to help U.S. manufacturers design and develop products to meet this
specification.
We look forward to the near-term market introduction of reliable, energy-
efficient, and competitively priced rooftop units that increase the energy
efficiency of the sector. 12
