The U.S. Department of Energy (DOE) is updating the test procedures for compressors to correct errors and ensure calculations are accurate across different conditions, such as altitude. These changes include fixing formulas for efficiency calculations and updating the definition of "air compressor" to clarify that multiple compression elements are included. The updates align DOE procedures with industry standards and are designed to be more precise without adding extra testing burdens on manufacturers. The updated rules will be effective April 2, 2025, and mandatory for product testing by July 16, 2025.

The U.S. Department of Energy (DOE) has proposed a tentative decision that the current industry test procedure for commercial warm air furnaces (CWAFs) does not accurately reflect their energy efficiency. This new determination critiques the industry's method for failing to consider jacket losses and part-load performance, which impact the true energy efficiency of the equipment. DOE plans to apply a revised test procedure (called TE2) that accounts for these factors and is seeking public comments on this proposed method before making a final decision. Stakeholders can submit their feedback to help ensure the new test procedure is fair and representative of the furnaces' real-world performance.
