The energy performance certificate (EPC) or energy passport is the quality label that defines the energy performance of a residential building. The certificate provides information on the energy efficiency of residential buildings and thus allows comparisons to be made with other residential buildings. Thus, even without technical knowledge, the consumer can assess the energy quality of a residential building.
With the introduction of the smart meter, the consumer receives more detailed information on their consumption habits, enabling them to save energy by changing their behaviour.
Smart meters make it possible to read energy consumption remotely, meaning that staff do not have to disturb customers in order to read their meter on site.
Thanks to smart meters, electricity and natural gas providers will be able to offer customers increased flexibility for innovative pricing and invoicing based on supply and demand in energy markets. Suppliers will thus be able to offer new tariffs that better correspond to consumption habits and issue an invoice at any time of the year based on actual consumption instead of estimates.
A smart meter makes it possible to read energy consumption remotely, i.e. without having to travel to the consumer’s premises. The provision of near real-time information to the consumer will enable them to monitor and control their consumption and energy costs.
Smart meters are part of the reform of the energy markets aimed at encouraging active consumer participation. The smart meter is the first step towards the implementation of a smart electricity distribution network that uses computer technology to optimise decentralised production, distribution and consumption, especially with regard to electromobility, as well as to better coordinate supply and demand between electricity producers and consumers.
The deployment of smart meters is among the measures planned by the Luxembourg Government to enact the European energy directive into national law.
Smart meters use state-of-the-art technology in order to measure the energy (electricity, natural gas, urban heat) or water consumption of each dwelling at regular intervals. The meter records the values and transmits this data via the existing electricity network to a central system, which collects the data from the meters for the whole country and transmits it to the network operator.
The central data collection and management system is managed and operated by the Luxmetering economic interest group, which was created in 2012 by the country's seven electricity and gas network operators: Creos Luxembourg, City of Ettelbruck, City of Diekirch, Electris, City of Dudelange, Sudstroum and Sudgaz.
It should be noted that the network operator builds and operates the electricity or natural gas networks, and that the supplier buys and resells energy and associated services.
LENOZ is an optional global assessment strategy, adapted to the Luxembourg market, for quantifying the sustainability of housing. LENOZ stands for Lëtzebuerger Nohaltegkeets-Zertifizéierung.
