Measurement, metering and display,the first step towards sustainable savings

Measurement is the basis of all diagnostics.By monitoring your consumption, you can makesavings of 8 to 12%. And by combining this withaction plans, you can optimise performance andcommit to a sustainable development process.Energy efficiency requirements in commercialbuildings will encourage the use of measurementby load type, in each consumer unit, withconsumption displayed as close as possible tothe user (heating, cooling, hot water production,lighting, cooking, power sockets).

Legrand solutionsIn addition to energy meters, measurement controlunits and the new DX3 or DPX3 protection devicesincorporating measurement functions, Legrand hasdeveloped an ecommunication infrastructure fordisplaying information on reactive power consumption,voltage disturbance, harmonic distortion, etc. according tothe type of building (low consumption/high environmentalquality, whether in use or being refurbished).

2 solutions for displaying the consumption of buildings:Installation of the Measurement application on adedicated PC, or direct connection to a web server.Then, directly configure (in 3 steps) the display of theconsumption of the buildings

To use remote display with the web server:- If you are on a company network, ask you IT department for a fixed IP address- If you have a box, ask your service provider for a fixed address
