Solid-state emitter-based lighting (LED type) is considered to be twice as efficient as that produced by conventional incandescent lamps. The generalisation of their use requires the development of metrological methods and instrumentation in order to characterise their performance in an univocal manner.

Objectives

Improve the qualification of LED (light-emitting diode) lighting: evaluate colour rendering metrics applied to LED-based lighting

Better qualify LED lighting: develop a basic model for predicting the visual comfort of LED lighting.

The electrical grid is currently undergoing profound changes throughout the world. Indeed, the current supply networks, which are centralised and incorporate a large share of fossil fuel power plants, must migrate towards an increased integration of renewable energy sources (RES). The energy landscape is therefore evolving towards diversified and decentralised production.

Objectives

The general objective of the European project is the development of a metrological infrastructure, so as to successfully implement a smart electrical grid in Europe

The objective of the associated RNMF project is the realization of a reference PMU that can be used for on-site measurements and laboratory tests

In order to anticipate the depletion of fossil resources (oil, gas, coal) and to reduce greenhouse gas emissions, current governments are encouraging the development of biofuels, produced from non-fossil organic materials. The European Directive 2009/28/EC thus promotes the use of biofuels and other renewable energies in transport.

Objectives

Develop reference materials and methods to ensure conformance of measures for first generation liquid biofuels (bioethanol and biodiesel)
