2 Measurement, metering and display, the first step towards sustainable savings Measurement, metering & display via e communication Measurement is the basis of all diagnostics. By monitoring your consumption, you can make savings of 8 to %. And by combining this with action plans, you can optimise performance and commit to a sustainable development process. Energy efficiency requirements in commercial buildings will encourage the use of measurement by load type, in each consumer unit, with consumption displayed as close as possible to the user (heating, cooling, hot water production, lighting, cooking, power sockets). Legrand solutions In addition to energy meters, measurement control units and the new DX or DPX protection devices incorporating measurement functions, Legrand has developed an e communication infrastructure for displaying information on reactive power consumption, voltage disturbance, harmonic distortion, etc. according to the type of building (low consumption/high environmental quality, whether in use or being refurbished).

CENTRALISED DISPLAY FOR OPERATING MANAGERS Measurement via e communication on PC screen Remote display, for a set of buildings, of the measurement information from various main LV distribution boards (MB) or secondary boards (SB). One IP address per consumer unit. Used for the real-time display, measurement and recording of consumption.
