Situation of the Brussels Region
•162 km² - 62,5 square miles
•1,1 millions People (+13% 2001-2010 and
expected + 25% by 2060)
•630.000 workers (+8% 2001-2010)
•75% of energy consumption by buildings
•Old building stock
•Very low renewable energy potential (3%)
•Large regional competences: environment,
energy, mobility, urbanism, housing, …
•
Ambitious policy: Reduce 30% of
Greenhouse gas emissions by 2025

Plan for Local Action for the
Management of Energy
How can a building manager save
15 to 30% on consumption
without too much investment?
9
P.L.A.G.E. objectives
1. To assess the consumption of buildings and
energy efficiency
2. To identify potential energy savings and
priorities for action
3. To organize internal management towards an
efficient maintenance of buildings
4. To integrate energy efficiency in investment
decisions
P.L.A.G.E. in five steps …

STEP 5 : to follow-up the actions and analyse the results

se termine par un plan d’action.

P.L.A.G.E. SO FAR …
More than 1.380 buildings  4,5 millions m²
of which 2 millions m² were put in PLAGE Action Plan
Focus on actions with low financial impact
Results:
-
Decrease by around 15 % of fuels consumption
-
Stabilisation and even reduction up to 4% of electricity
consumption
4,25 millions € / 5,5 Mio $ saved;
35 Energy Managers engaged.

… and five keys of success!
KEY 1 : not only an energy manager but an ENERGY TEAM
KEY 2 : know WHO DOES WHAT in the BUILDING
KEY 3 : CONCERTED DECISION MAKING about actions to implement
KEY 4 : Manage the actions at EACH level and RESPONSIBILITY of
each one
KEY 5 : Give a FEEDBACK and promote the results

-
one for decision-makers,
-
one for energy managers
