Substitution from heating oil to biomass for
the heating system of an hospital
“The EUREM training showed me new topics to work
on, especially on renewable energies. I am really glad
I took this training.”
Energy concept description: The heating system of the hospital is
composed of boilers fuelled with heavy oil. This system is ageing
and needs to be replaced. Under the framework of its contract of
maintenance and operation, the hospital board asked for more efficient
and ecological solutions to be researched.
► A comparative technical, economical and environmental analysis
underlined the benefits of a biomass plant on the middle and long
term.
► A site study has been made to check the compatibility of the site
with the supply.
► The consumption substitution reaches 11 GWh: the biomass boiler
will cover 80% of the needs and the remaining 20% will be covered
with a gas boiler. Thanks to local sourcing the environmental gain
will be maximised to 2,700 tons of CO2 a year compared to the current
situation.
Results:
The old heavy oil boiler to be replaced
Energy saving potential: 11.000 MWh/a
Energy source: Biomass (80%) and gas (20%)
Cost reduction: 150.000 €/a
Co2 saving potential: 2.700 t/a
Investment costs: 1.250.000 €
Pay-back time (static): 8 years
Likelihood of implementation: high

Efficient public lighting in a city
“Thanks to the energy concept of the EUREM training,
I have been able to develop an efficient solution for the
public lighting of Cesson.“
Energy concept description: The public lighting system in Cesson
is getting old and needs to be replaced. The city is looking for the
most economical solution.
► The public lighting system is actually composed of mercury
vapour lamps fitted with ferromagnetic ballasts. The material does
not meet the new standards and needs to be changed.
► The new system will be composed of sodium vapour lamps fitted
with electronic ballasts. It will also involve dimming, which allows
additional energy savings and reduces light pollution. The new
lamp posts will also have an improved degree of watertightness
and also be more resistant to vandalism, meaning more economies
on maintenance.
► Some 350 MWh of electricity will be save each year in Cesson
meaning some 240 tons of CO2 avoided.
Results:
Energy saving potential: 350 MWh/a
Energy source: Electricity
Cost reduction: 12.000 €/a
Co2 saving potential: 240 t/a
Investment costs: 2.000.000 €
Likelihood of implementation: high
Inefficient lamp posts wasting energy and money
