Small Network Equipment: Considerations for Energy Efficiency Policy
This report provides an overview of small network equipment (e.g. routers and modems), investigates options for policies and estimates the potential for energy savings.
AC/HP Test Methods 2.0: Phase 2 Findings Summary
This research aims to develop an internationally applicable load-based test method for variable capacity ACs and HPs and has 4 Phases. This report discusses the findings of Phase 2 (Investigative Testing of Key Issues), as well as the research team’s recommendations for Phase 3 work.
Literature Summary of Lifetime Testing of Light Emitting Diodes and LED Products
A summary of the literature on lifetime definitions for LEDs and LED products, including a look at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test method can best estimate the lifetime of LED lighting products and the report thus addresses a key issue for regulators and industry interested in deployment of LED technologies
