Memorandum

To United States Department of Energy

From Michael Rivest, Navigant Consulting, Inc.

Date February 10, 2015

Re: Ex Parte Communication

On Friday, February 6, 2015, the U.S. Department of Energy (DOE) conducted a public meeting on the

Notice of Proposed Rulemaking (NOPR) for Single Package Vertical Unit (SPVU) energy conservation

standards. 79 FR 78614 (December 30, 2014). Subsequent to the conclusion of the meeting, a staff

member from Navigant Consulting, Inc., working in support of DOE, was approached by a representative

of the Air

‐ Conditioning, Heating, and Refrigeration Institute (AHRI) and asked for written clarification on

a value presented in the NOPR notice and Technical Support Document (TSD). Seeking to provide the

requested clarification, the Navigant staff member responded via email later that day, providing the

attached correspondence, and received a confirmatory email in response from the AHRI representative.

The following individuals were involved in the exchange:

Samuel McClive, Navigant Consulting, Inc.

Amy Shepherd, Air

‐ Conditioning, Heating, and Refrigeration Institute

Respectfully Submitted,

s/ Michael Rivest

Subject: Gas Heat SPVU Question

Hi Amy,

Thank you for your question earlier at the SPVU Public Meeting about the share of SPVUs at 10 EER

which use a PSC motor and are also gas heat.

The answer is that 18 out of 21 SPVAC units are gas heat w/ a PSC motor, whereas 18 out of 27 SPVU

units in total are gas heat w/a PSC motor. In other words, there are 6 SPVHP units which have a PSC

motor but are non

‐ gas heat, which were lumped into the relevant sentence in the TSD (21+6=27), but

were not in the relevant sentence in the NOPR.

Hope this clears things up, and sorry for the confusion.

‐ Sam
