Final Draft Version 2.0 ENERGY STAR EPS Specification Revised Once Again; Comment Period Extended

The US Environmental Protection Agency (EPA) announced that, after releasing the Final Draft Version 2.0 ENERGY STAR EPS specification on February 19, 2008, the EPA was alerted to a discrepancy in the masked dataset by an industry stakeholder. The EPA has reviewed the EPS analysis used for the Final Draft levels and has identified and corrected two errors found in how the analysis determined the qualification criteria (No-load power and Active efficiency) for some products.

After correcting these errors and studying their effects, the Agency determined that the Active efficiency levels included with the Final Draft were more challenging than intended and has therefore relaxed the Active requirements in order to remain consistent with ENERGY STAR program principles for a revised EPS specification.

No other changes have been made to the proposed specification. The newly proposed levels provide an overall qualification rate for No-load power and Active efficiency of 27.4% with similar qualification rates across the different wattage bins as the Final Draft release. Due to this change in Active levels, the EPA has extended the comment deadline for the Revised Final Draft Specification to March 18, 2008.
