The economic commitment that a
company must sustain for the requirements of electric and thermal energy,
suffers from many and various factors, tied both to the internal
characteristics of use and to the debit policies of the supplying body.
Effective management is only possible thanks to technological tools that enable
the activation of appropriate optimization and savings systems. An industry
that intends to consume less must have solutions that allow a rational use of
energy, which must be considered as a strategic component of the company's
business, which must develop a policy aimed at reducing consumption.
It is therefore necessary:
- to determine the incidence of
energy costs per production unit;
- to avoid unnecessary costs due
to poor quality and energy’s management.
RENOVIS designs, manufactures and
manages energy efficiency systems for small, medium and large industrial and
commercial companies. Furthermore, it guarantees the complete assistance to the
customer during the whole life cycle of the plant, through its own team of
technicians and engineers specialised, prepared, and by the use of
instrumentation with a high technological content, put in place to allow the
full achievement of the efficiency results foreseen during the study phase of
the work. The service offered extends to the entire process of realisation of
the intervention: from the evaluation of energy, environmental, logistical and
economic feasibility, to the preliminary investigation of all authorisation,
environmental, fiscal and safety practices, up to installation, commissioning
and subsequent management.
More specifically, the operational
procedure conducted by RENOVIS is
divided into the following phases:
- Pre-feasibility analysis: the RENOVIS technicians meet the customer and give an initial general
assessment of the current state of the plant and the possibilities for
intervention, based on inspections and consumption data provided by the
customer himself.
- In-depth on-site energy
audit: once the preliminary technical and economic
cost-effectiveness of the intervention has been established, RENOVIS takes care of obtaining from
the customer the entire energy data fundamental for an in-depth analysis of the
current situation of the plant, also through highly technological measuring and
monitoring instruments.
o Census of users
o Collection of information on
the operating characteristics of the system, the adjustments adopted (if any),
the annual use (hours of operation)
o Measurement of consumption through
the installation of appropriate measurement systems
o Possible installation of test
systems on non-regulated systems, for which it would be impossible to model the
behaviour of the system mathematically.
- Data analysis: based on the data collected, Renovis elaborates the technical and
economic feasibility of the intervention (cost/benefit assessment - estimation
of potential energy savings and cost of solutions).
- Commercial proposal: The results obtained are presented to the customer, together with
the energy efficiency plan and the assessment of the return on investment
(ROI).
- Design: RENOVIS uses special software (e.g. Simulink®) to develop processes
to simulate the pre-operam situation and the post-intervention operation of the
system, highlighting its favourable aspects from an energy and monetary
economic point of view. This is because it is fundamental for RENOVIS to
analyse the performance of the systems in different working conditions. In
doing so, all the physical laws at the basis of the processes are considered,
in addition to the operating constraints required by the production logic
(hours of activity, plant restrictions, quantitative and qualitative
characteristics of the final product, etc.). RENOVIS is able to produce an
appropriate model of the initial situation of the plant and to study different
possibilities of regulation. The use of appropriate design software essentially
involves two successive phases: model definition and model analysis.
- Financing of the project.
- Preparation of a PPPM (Proposal
for a Project and Programme of Measure) for the request of access to the
economic benefit of TEEs.
- Realization and installation
of the efficiency system and of the measurement system: once the real convenience of the intervention has been verified and
the customer has given his consent, RENOVIS takes care of the complete
realization of the work together with its partners, without the customer having
to bear any inconvenience. It also provides for the implementation and
installation of the measurement and monitoring system necessary to determine
the amount of savings achieved as a result of the additional work at the
expense of the customer
- Installation and
Commissioning: once the project has been completed,
RENOVIS installs the new system and remains close to the customer as regards
assistance in the event of malfunctions and the progressive monitoring of the
energy savings achieved (see the section on "measurement and
monitoring").
- Assistance, determination
and reporting of savings (RVC)
The entire manufacturing process
is carried out in compliance with the regulations in force in the field of
industrial energy efficiency, with the help of all the scientific knowledge
relating to the field of study and the best technologies available on the market.
The analysis and design timing ranges from a few days to a few weeks, depending
on the users to be monitored. The commitment for the customer is almost absent:
it is required the support (for a few hours) to RENOVIS' personnel by an employee who knows the systems, is able to
provide the necessary information and can operate on the switchboards.
Very flexible contractual solutions allow the
customer to cancel the investment costs when operating in EPC mode (see
"sales and financing" section), while a highly qualified technical
assistance service ensures the continuous and constant availability and
efficiency of the plants, maintaining their technological value throughout
their useful life.
