Energy Management

Energy Management
Ge.Ser.Ind. has a strong competence in the energy
management field, providing services concerning the
support and control of energy costs and consumption.
It collaborates with european partners in audit and
advisory activities for customers.
We help our customers in capitalizing their own resources,
optimizing them and avoiding possible wastes.
Our duty consists in supporting you with a constant and
personally customized dedication.
A significant reduction of energy costs is possible only with
a careful control of the energy utilization. Through an
analysis of the customer’s characteristics, his consumption
and the related energy costs we can find a strategy leading
to a greater awareness and a resulting optimization of the
energy consumption.

ENERGY AUDIT:
Electric Consumption
The first step to energy management
is the knowIedge of how energy is
consumed.

“You can’t manage what you don’t
measure...”
The first tool to know the energy
consumption is the ENERGY AUDIT.
Generally an energy audit leads to
detect interventions of potential
savings ranging from 15% to 20%.

ACTION PLAN EXECUTION:
No/low cost interventions
Ge.Ser.Ind. can support the
customer in writing the
maintenance procedures to put in
practise and the documents to
standardize such interventions
Investments with returns
Ge.Ser.Ind. can support the customer with:
•
•
•
•
•
•
•
•
Feasibility verifications
Detail design
Requesting proposals
Evaluating proposals
Work direction
Safey coordination
Tests
Procedures to get energy efficiency titles
(white certificates)
TRAINING:
Who’s aimed at
Production and maintenance staff
Objectives
Focused training to teach the production and
maintenance staff how the energy management
system works (according to the EN 16001 and ISO
50001 regulations based on the “continuous
improvement”) and to sensitize the staff about the
relevance of their activities to reach the saving of
energy consumption.
CONSUMPTION CONTROL SYSTEM AND BMS (Building Management System):
It’s necessary the introduction of a network of meters (to control the
consumption over time) and an integrated management system.
Ge.Ser.Ind. can help the customer company in designing, choosing and realizing
such systems.
White certificates or Energy Efficiency Titles (TEE)
They are state incentives which fund interventions aimed to
realize improvements in energy efficiency.
These titles are released by AEEG through ENEA; projects must
be presented to ENEA which evaluates the respect to the
necessary requirements to release the titles.
These titles can be sold to subjects or inside the Stock Market.
E.S.Co. can present projects to obtain the white certificates.
Ge.Ser.Ind. as an E.S.Co. can present projects to obtain White
Certificates and allow the customer company to get additional
economic benefits.
ENERGY MANAGEMENT SYSTEM (EMS):
Without an energy management system
based on the continuous improvement
any effort leads to results of limited
duration.
The best strategy for a constant
consumption reduction is managing the
energy according to the standards
introduced by the EN 16001 and ISO
50001 field regulations.
Results
The results of the introduction of a management system and an energy
audit are encouraging:
• implementing only the no/low cost interventions you can obtain savings
of 5-10%
• with mid-term investments (returns in 1-3 years) you can achieve
savings of 10-15%
• the introduction of a management system allow to reach values around
15-20 % and to keep such results over time
