Strategic evolution
Public service of
energetic
management
By means of public auction is intended the evolution of
maintenance service to energetic management.
Maintenance service
Maintenance agreement includes:
 Schedule of energetic management tasks.
 Terms of contractor’s commitment with energy performance
goals.
 Set of common resources developed by contractors’ team to
spread among them knowledge about energetic management

4. 4
 Energetic management tasks:
1.- Analysis of energy cost and consumption
2.- Facility monitoring
3.- Energetic audit
4.- Catalogue of actions and investments
Strategic evolution
Some results:  9,1% savings in electrical spending in educational
facilities [1.-][4% initial goal]
 105 building monitored [2.-]
 11,5% savings in overall electrical consumption in
educational facilities [4.-][on first stage]

5. 5
Administrative innovation
Public auction settlements lay the conditions in order to evolve
towards energetic management.
This is achieved by means of:
 Investment of marginal cost dedicated to maintenance service
as funds to develope energetic management project.
 Settlement of impulse comittee as collaborative meeting point
to share and circulate knowledge.
 Development of common standards to evaluate the results of
the different energetic management tasks.

6. 6
Technical innovation
The deployment of the project supposes the acquisition of
innovative software to proceed to data analysis.
DEXCELL Energy Manager is an innovative energy information system
developed by DEXMATECH, a catalan start-up founded in 2007.
 The energetic management project helps to consolidate the new
firm, so increases sensibly its amount of operations.
 The energetic management project provides strategic orientation
on defining main priorities to develope the software.
 The energetic management project offers the data needed to
perform a wide range benchmarking devoted to expand kowledge
about public facilities.

7. 7
Cultural renewal
The deployment of the project demands an innovative
approach towards the collaborative practives that become a
main issue to succeed .
These collaborative practices are settled on all levels of operation of the
energetic management project:
 Impulse comittee at managerial level.
 Casual teams established ad hoc among contractors at operational
and technical level.
 Local teams that involve facility users and managers, technical staff
and community agents.
