Smart Lighting – New Features Impacting Energy Consumption

Smart lamps and luminaires are common in today’s lighting market. Smart lighting provides an opportunity for the consumer to benefit from wireless control of lighting products, e.g. by dimming, colour tuning and scheduling. These functions can provide energy saving but they also require energy consumption to supply standby power and gateways. In 2016, the first […]

Guide to Energy Management Protocols

This report is a guide to ‘application layer’ communications protocols used for energy management, such as those used to facilitate intelligent efficiency and demand flexibility.

Mobile Device Efficiency

This report analyses the energy use of mobile devices, compares policies and identifies policy gaps.

Standardisation for Smart Devices

This report highlights the most relevant standards in areas such as measurement of energy consumption of smart devices, and communication protocols for smart devices.

Interoperability

The objective of this study is to gain a better understanding on the issue of (a lack of) device interoperability and the resultant impact of this on Intelligent Efficiency and Demand Flexibility

SSL Quality and Performance Requirements

The IEA 4E SSL Annex has published its new and updated “quality and performance requirements” for the most popular LED lamps and luminaires. These specifications are offer policy makers and programme managers guidance on the most important parameters to consider when specifying or regulating LED lamps and luminaires. Parameters include efficacy, lifetime, light colour, durability, […]

Progressing Energy Efficiency Policies for Systems

Systems are described as the next frontier for energy efficiency policy, offering the potential to unlock huge energy savings in equipment-based energy-using systems.
In this summary we highlight some of the key findings from 4E’s investigations over several years.

A “life cycle thinking” approach to assess differences in the energy use of SiC vs. Si power semiconductors

Wide bandgap (WBG) semiconductors have the potential to provide significant improvements in energy efficiency over conventional Silicon (Si) semiconductors. While the potential for energy efficiency gains is widely researched, the relation to the energy use during manufacturing processes remains insufficiently studied. This question is especially relevant for Silicon carbide (SiC) semiconductors, as there are some […]
