CQube – Grinder kit
This Energy Declaration provides a quantitative description of the energy use of an CQube Coffee Machine,
viewed from a life cycle perspective. It shows that most energy is consumed during the use phase.

The product
CQube – Grinder kit
CQube is a fully automatic brewer for fresh brewed
coffee in a cup or decanter. The machine
has an automatic water refill and 4 ingredient
containers for coffee, topping and chocolate.
Brewing time is 25 seconds per cup (150 ml).
The main materials used in the CQube are:
Stainless steel, ordinary steel with surface
treatment, plastic parts and electronics.
Total net weight of the machine is 53 kg. Volume of
the water container is 5 litres. (The figure at right
includes an extra cabinet with a weight of
approximate 25 kg)
Life cycle energy use
The diagram shows the withdrawal of
primary energy resources from nature
- oil, coal, wind, etc - during the life cycle
of the product. The unit is mega joule, MJ.
For example, most of the primary energy
consumed during the use phase stems from
electricity, which typically demands
8-13 MJ primary energy resource per kWh
electricity depending on where it is
Note that cutting wastes are sent for
materials recycling and the finished product
is likely to be recycled at the
end-of-life. The energy thus recovered is
not credited to the product since it belongs
to the next product system. However, since
the product contains materials made from a
mix of new and recycled materials the
benefits of material recycling are accounted

The life cycle
All data are given for one CQube – Grinder kit during
5 years of operation.
The investigated life cycle begins with the extraction of
resources and production of the materials for the unit.
Generic energy data are used for the materials. Specific
data are used for how much materials and energy are
used in every life cycle phase.
The manufacturing includes assembly, surface
treatment and warehousing. Electricity, district heating
and transportation are the major consumers of energy.
Life cycle cost, LCC
Assumed data:
The machine is used over a period of 5 years.
It is placed in an ordinary European office or
equivalent place with about 30 persons drinking
coffee. Assumed yearly production is 15 000 cups.
The Coffee machine is always prepared to serve
coffee, and the Ready Mode heating of water
(55W) is always active.
The Coffee machine needs service and repair 12
times every year, with an average 30 km driving.
End of life includes one transport of 20 km
Coffee and water are not included in the
Yearly cost = (yearly energy use)*(your own
energy price) + service cost
The total cost of a Coffee machine is depending on
Yearly service cost is depending on your agreement,
the purchase price, but also on the usage costs, which
as is the purchase price.
are energy, water, filter, coffee/chocolate and service.
For a comparison between two coffee machines, the
amount of coffee/chocolate, filter and water can be
assumed to be the same. That is why we here focus on the
special costs of this product. A simple calculation gives
Improve the product’s
energy efficiency during use
Life Cycle Cost = purchase price + yearly use cost
*product life.
To do a more sophisticated calculation, see LCC on or
The yearly energy use for a normal scenario, as
described above, is 705 kWh. The use consists of 2.2 kW
in 25 seconds per cup of coffee (150 ml) and 55 W
continuously in Ready Mode prepared to deliver hot coffee.
When not prepared to deliver hot coffee, called Energy
Saving Mode, the power consumption is 22 W.
Calculate your own yearly energy use [kWh] by
summing up the following four items
0.015*(number of cups/year)
(number of hours in Ready Mode per year)*0.055kW
(number of hours in Energy Saving Mode)*0.022kW
(number of hours in off mode) * 0 = 0 kW
*=multiply with.
The total number of hours is 8760 (1 year)
Use the correct size and model of coffee machine
according to your own requirements
Use Energy Saving Mode during shorter stops for
example over night time
Switch the machine off during longer stops as
weekends and vacations
Use the schedule tool to set the times for the
different modes
Keep the Coffee machine in prime operating
condition by regular service and maintenance
