FIRE: the association for energy efficiency
The Italian Federation for the Rational use
of Energy is a no-profit association founded
in 1987 that promotes energy efficiency,
supporting energy manager, ESCOs and other
companies dealing with energy.
Besides the activities directed to its nearly
450 members, FIRE operates under an
implementing agreement with the Ministry of
Economic Development to manage the Italian
energy manager network since 1992.
In order to promote energy efficiency FIRE
cooperates and deals with public authorities,
energy technology and service companies,
consultants, medium and large consumers,
universities and associations to promote best
practices and improve the legislation.
www.fire-italia.org
FIRE manages SECEM - an accredited body - to
certify the Energy management experts
according to the standard UNI CEI 11339.

FIRE: the association for energy efficiency
Besides being involved in many European
projects, listed next, FIRE implement surveys
and market studies on energy related topics,
information and dissemination campaigns,
and advanced training.
Some of FIRE clients over the years: Ministry
of Environment, ENEA, GSE, RSE, large
organizations (such as Centria, ENEL, Ferrovie
dello Stato, FIAT, Finmeccanica, Galbani, H3G,
Telecom Italia, Unioncamere), universities,
associations, energy agencies and exhibition
organizers.

SECEM
SECEM, European System for Certification in
Energy Management, is a certification body
created by the FIRE.
SECEM was the first body to offer third-party
certification for Energy Management Experts
(EMEs) according to UNI CEI 11339 and is
accredited according to the ISO/IEC 17024
standard.
In Italy two standards were developed in order
to promote the qualification of energy efficiency
operators: UNI CEI 11339 for EMEs was issued in
2009, UNI CEI 11352 for ESCOs was published
in 2010. A new standard for energy auditor is
presently under preparation.
www.secem.eu
Both the mentioned standards are recognized
from the national legislation within the energy
audit obligations for large companies
introduced by the EED directive and the white
certificate scheme.

Saving evaluation methods in Italian WhC
Deemed savings projects (progetti standard): the saving is evaluated with
respect to the number of installed reference units (e.g. square meter, kW,
number of installed units). No measures are required. Only standardized
solutions can be included in a deemed saving file. The proponent presents
an RVC once.
Scaled savings - engineering estimates (progetti analitici): the saving is
evaluated with respect to some measured quantities through a dedicated
algorithm defined in a dedicated file. Required meters are also indicated in
the dedicated file. The proponent presents an RVC at least once a year.
Metered saving (progetti a consuntivo): the method is similar to the
previous one, but the algorithm, the baseline, the additional saving
coefficient, and the needed meters should be preliminarily proposed by the
applicant PPPM and approved from GSE (with ENEA-RSE). After the
PPPM is accepted the proponent will get WhC by presenting an RVC at
least once a year.

Points to be considered for measurements
Deemed savings
Scaled savings
The method is easy to use and
facilitates the evaluation.
The method is easy to use and
facilitates the evaluation.
Savings are not measured and
monitoring can be complex if
multiple solutions are considered.
Savings are measured.
Required documentation: choice
to go easy or bureaucratic, which
usually implies a failure, unless
the incentive is very high.

Metered savings
The method is usually complex,
especially if additionality or
detailed adjustments are present.
Savings are measured.
Required documentation: is
usually substantial, but the size of
the project allows it.
On field controls are usually a
viable option.

Effort required to evaluate
baselines, additionality, and other
needed information.
Effort required to evaluate
baselines, additionality,
algorithms and meters to be used,
and the other needed information.
High cost-effectiveness.
High cost-effectiveness.
Possibility to pre-evaluate EE
products in order to ensure the
required performance.
Simplified monitoring plans?
Effort required to evaluate
baselines, additionality,
algorithms and meters to be used,
and the other needed information
for both the proponents and the
evaluators. Shall data be available
for everybody?
On field controls are expensive.
Very flexible, but potentially
costly and complicated (viable for
high targets).
Measuring EE savings is really an hard task.
Metered savings can really boost flexibility.

Ptacs
potenza termica nominale dei generatori per produzione di a.c.s., nella configurazione post-intervento; nel caso
in cui non sia presente un generatore separato per a.c.s., questo valore coincide con quello di Ptrisc [kWt]
coefficiente correttivo che assume valori diversi da 1,00 nel caso in cui l’intervento riguardi sistemi dotati di
termoregolazione e contabilizzazione locale del calore [-]; i valori possono allora essere:
- 1,22 per le zone climatiche A, B e C,
Allegato A alla deliberazione EEN 9/10 così come modificato dalle deliberazioni EEN 14/10
- 1,18 per la zona climatica D,
- 1,15 per le zone climatiche E e F.
