Object metering
“To measure is to know”
Electric bills keep getting bigger and bigger, and
increased consumption probably plays a bigger part than
higher prices. At home and at work, energy-hungry items
like computers, terminals, servers, climate-control equip-
ment and intense lighting all push up costs. One of the
simplest ways to save money and energy is to make elec-
tricity consumption more visible – via object metering.
Object metering is metering individual commercial freezer,
lighting, machines, power-consuming objects such as
air-conditioning fans or heating pumps. Its aim is to show
electricity use where it occurs, thereby increasing energy
awareness and helping change consumer behavior.
Simple, MID-approved meters are preferred
Object metering requires no special approval but an approved,
high-quality meter rather than a non-approved will always be
preferable.
Easy installation in standard enclosures together with
MCB protection
ABB’s compact electricity meters are easy to install in
standard enclosures. This is especially important in object
metering since objects in domestic, commercial and industrial
applications require line protection devices, and these are
generally mounted in standard enclosures.
Long list of domestic objects
Heating and ventilation pumps are obvious candidates for
object metering in the home, and these can be joined by
appliances such as washing machines and dishwashers as
well as other electronic equipment. And don’t forget outdoors.
Garden terrace heaters and lighting plus the pond pump are
all significant ‘energy thieves’. The actual consumption of all
is easy to measure and see (and therefore save) via compact
meters in the home.
Many opportunities in commercial properties
Commercial properties naturally feature a wealth of objects to
measure, including many of the items found in everyday homes.
But engineers are now exploring ways to get modern,
large-scale buildings to produce energy as well as consume it.
Elevator cars, for example, generate energy when they descend
or brake and this can be returned to the building’s power grid
as electricity for lighting or heating.
Imported and exported measurement data is usually collected
by the meter, and fed to a Facility Management System for
analysis.
Industry shares similar needs
In addition to normal units for heating, lighting, ventilation and
office administration, industrial premises contain usually
processing machinery, conveyers, transport systems, and a
great deal of electrical protection devices. Object consumption
data measured by meters can be fed to Energy Management
Systems for analysis to see how energy costs can be cut.
Object metering makes electricity consumption more visible, increasing
energy awareness and helping consumers save on their bills.
