LOCAL ACTION PLANS
FOR ENERGY MANAGEMENT
EMMANUEL HECQUET
CICEDD, NAMUR. HE HAS BEEN WORKING IN PARTNERSHIP WITH BRUSSELS
ENVIRONMENT ON THE IMPLEMENTATION OF THE "PLAGE" PROJECTS SINCE 2006
THE GOAL OF THE PLAGE PROJECTS IS TO IMPROVE ENERGY EFFICIENCY IN
BUILDINGS IN THE BRUSSELS REGION IN ORDER TO ACHIVE ENVIRONMENTAL
AND COST SAVING BENEFITS THROUGH THE IMPLEMENTATION OF PROACTIVE
ENERGY CONSUMPTION. SIGNIFICANT RESULTS HAVE BEEN ACHIEVED SINCE
THE LAUNCH OF PILOT TESTS IN 2006.
The regulatory background to the
programme of Local Action Plans
for Energy Management (PLAGE)
is the European Directive 2012/27
on Energy Efficiency and the
implementation of that directive
throughout the Region, imposing
a reduction of 30% in greenhouse
gas emissions by 2025 compared to
1990 levels.
OBJECTIVES AND METHODS
USED FOR THE PLAGE PROJECT
The goal of the PLAGE project is
to manage energy consumption
with a view to reducing it. It targets
managers or owners of large building stocks, as well as occupants,
encouraging them to take actions
that will produce rapid results. The
programme includes pilot tests and
will take place over three to four
years. The project primarily focuses
on rationalising energy use, application of regulations and insulation of
boiler installations than on making
heavy investments. We therefore
try to optimise consumption with a
priority on heating and (to a lesser
degree) on electricity. This programme applies to existing buildings, not to new buildings or buildings that have been the subject of
extensive renovation works.
We used a specific process quality
method or ISO, namely the Deming
Wheel (fig. 1). This is a continuous
improvement process. PLAGE
focuses first on energy accounting, or more precisely what we
call the "energy register", as well
as an administrative and technical inventory of the building stock.
This first stage may be laborious
depending on the number of buildings. In the municipalities where
the PLAGE project was launched in
2006, the mere creation of a register
(involving up to 100 to 150 buildings)
took some time. The objective is to
identify "priority" buildings: those

that offer the greatest potential for
energy savings for the lowest cost.
This is followed by a three- to fouryear action plan involving the close
monitoring of energy consumption.
We analyse the initial results of this
energy accounting process, evaluate
them and then carry out corrective
measures where necessary. The
register and the action plan are then
updated and a new cycle begins. The
idea is to enter a virtuous circle for
improving the energy consumption
of the building stock.
The preparation of the action plans
allows us to draw up an outline of
the technical and energy aspects
of each building. The priorities are
always low-cost measures (e.g.
management of boiler installations,
rationalising energy use (RUE), and
generating awareness among the
occupants or training technical services). We then analyse the results
and energy consumption month
by month, year by year, to see if
