ENERGY STAR SHEMS Draft 1 Version 1.0

Mon, 05/20/2019 - 10:07 -- MrGreen

On April 12, the U.S. Environmental Protection Agency (EPA) held a webinar to review Draft 1 of Version 1.0 of ENERGY STAR Smart Home Energy Management Systems (SHEMS). The intent of this program is to recognize smart home system packages that save energy and deliver cost savings and convenience by providing reliable vacancy detection, limiting standby power of connected devices, and providing users feedback on the energy impact of their settings. The key concept is that smart devices plus occupancy information plus automated services equal energy savings.

Changes Considered in ENERGY STAR Computers Version 8.0 Draft 1

Mon, 05/20/2019 - 09:58 -- MrGreen

The standard for ENERGY STAR Computers is under revision, and on April 16, representatives from the U.S. Environmental Protection Agency (EPA) held a webinar with stakeholders to discuss proposed updates in Draft 1 of ENERGY STAR Computers Version 8.0. According to the EPA, market penetration for desktop computers is currently 52% and for workstations 21%. As such, the EPA is proposing more stringent ENERGY STAR criteria for desktop products, consolidating desktop categories, reducing base allowances, and adjusting adders and mode weightings based on more recent data. For workstations, the EPA plans to maintain the existing energy requirements from Version 7.1.

California Energy Savings Roadmap for Electronic Devices in Low Power Modes

Fri, 03/08/2019 - 13:48 -- MrGreen

The California Energy Commission (CEC) is in the early stages of establishing an energy savings roadmap for electronic devices in standby, idle, or general low power modes (LPM). Although the standby power consumption in a device may seem small relative to the active power, the proliferation of such devices in California residences and the long durations of those devices spent idling have resulted in a significant total in energy waste, providing no utility to users. On January 24, 2019, the CEC held a webinar to provide an overview of the LPM roadmap, cover the proposed scope, review stakeholder comments received, and summarize the next steps.
