DOE has published a Federal Register notice of a public meeting and intent to establish the dedicated purpose pool pumps working group to negotiate a notice of proposed rulemaking (NOPR) for energy conservation standards. 80 FR 51483 (August 25, 2015). For more information please see the rulemaking webpage.
Draft PEI Calculator for Pumps as Measured by DOE's Proposed Test Procedure (80 FR 22939 (April 24, 2015).
This Excel spreadsheet is designed to perform the calculations necessary to determine PEI – a pump’s energy index -- as proposed in DOE's Notices of Proposed Rulemaking (Dockets EERE-2011-BT-STD-0031 and EERE-2013-BT-TP-0055). Under the proposals, the PEI calculations must be performed using measured values – that is, using results from testing actual pumps in accordance with the proposed test method and sampling plan. The PEI calculator is not considered an Alternative Efficiency Determination Method (AEDM) by the Department and would not to be used to simulate or estimate the efficiency of a pump.
DOE is providing this "calculator" as a convenience at the request of interested parties. Interested parties should consult the Federal Register for the proposed formulas for calculating PEI and should not rely on this spreadsheet. Dockets EERE-2011-BT-STD-0031 and EERE-2013-BT-TP-0055 (available at www.regulations.gov ) contains DOE's proposed rules for the standards and test procedure, respectively. While this calculator is an excel-based version of the calculations in the test procedure proposal, DOE did not rely on this document to develop the proposal itself. The draft PEI calculator is located here.
