Energy Management

The Software Solution to monitor consumption and environmental parameters in Industrial Plants and Buildings

Today, more than ever, energy efficiency is of great importance and is related to a good resources management, therefore no matter how much you spend on technological equipments, if the energy resources are not managed efficiently, wasting is close-at-hand. For this reason, it is essential to have a global control of energy resources. 

Zucchetti produces technological systems for the intelligent management of energy flows, in order to undertake all the actions aimed to strongly reduce consumption and costs. The ZEnergy system provides an innovative service for energy efficiency measurement, accounting and monitoring of the environmental quality within the buildings, according to the parameters imposed by sustainable construction principles.

ZEnergy allows measurement and accounting of energy consumption of:

  • heating systems;
  • air-conditioning systems;
  • electrical installations;
  • lighting systems;
  • photovoltaic installations;
  • cogeneration installations.

The European Directive 2012/27 makes the goal of making a 20% improvement in energy efficiency by 2020 binding, and requires organizations (real estate assets, public administration, industries) to carry out real energy performance improvement interventions in their assets. Commercial buildings absorb 40% of total energy demand (Source: USA Energy Department).

Excluding labor costs, energy costs account for 30% of a building’s total running costs and even more so in Italy, where energy bills are 18% higher than the European average. Italy has acknowledged the European Directive by means of a specific decree that provides for the adoption of structural measures and technological tools that aid energy efficiency. This is why Zucchetti is studying solutions that allow companies and organizations to compete in the energy and facility management market, also in observance of ISO 50001 energy saving certification.

ZEnergy is the Energy Management solution dedicated to monitoring consumption, environmental parameters and to analyzing energy efficiency that allows you to organize energy cost saving.

Thanks to the full integration with ZMaintenance, Zucchetti’s software to control technical and maintenance activities, ZEnergy allows to manage all technical and maintenance processes of the managed asset. A particular focus is set on the management of energy plants, such as the management of the plant and of the thermal power station documents.

The offer of access control – sector in which Zucchetti is the leader – video surveillance and anti-intrusion solutions, together with the energy and maintenance software solution, makes Zucchetti a reliable and preferred partner, to contact when the integration of advanced building automation systems is needed.

The hardware system is composed of the following elements:

  • Field data detection sensors (network analysers, electricity meters, flow and heat gradient meters, indoor and outdoor detection sensors of ambient parameters such as temperature, humidity, luminosity, air quality, etc.)
  • Electronic data capture system able to interface with all detection sensors specifically installed and preset also for the connection to other devices, already available on-site (e.g. gas, water, light meters, devices for Building Automation, etc.).

The software system is the application dedicated to Building Energy Management. The application is fitted with standard functions, such as data acquisition, storage, aggregation, control, analysis and many more.

Why is it important to be energy efficient?
The main problem in today’s world is that, in a global context where energy is still largely obtained from combustible fossils - and will continue to be that way for several years - the enormous, growing use of energy brings with it significant consequences of pollution and global warming, due to the high greenhouse effect emissions.

The realization thus dawned - and political initiatives and regulations have been developed in this sense - that in addition to reducing greenhouse gases and to aiding renewable sources, it is vital to set up energy saving and efficiency initiatives, using newly-developed technologies, that allow for improved energy performance.

Which legislative directives on energy efficient exist ?
Worldwide, several protocols and agreements have been signed in recent years, the latest of which being the Paris Convention in 2015, which commits the countries to limiting global warming to 1.5 OC by 2050.

In 2007 the European Union set the 20-20-20 plan, the main goals of which - to be achieved by 2020 - are:

  • a 20% reduction in greenhouse gas emissions (compared to 1990 levels);
  • 20% of energy coming from renewable sources;
  • a 20% improvement on energy efficiency.

European legislation has been increased and updated, in particular with Directive 2012/27/EU on energy efficiency that was acknowledged in July 2014 in Italy, by the coming into force of the legislative decree 102/2014. Among other things, this decree imposes an energy audit on energy-intensive companies.

What is an energy audit?
An energy audit is a set of actions and interventions - that are mandatory for some types of companies - aimed at analyzing and evaluating diagnostics, at rationalizing and optimizing energy performance and consumption and at reducing pollution emissions in a building.

What are the energy certifications?

The main certifications are:

  • ISO 50001: this is a voluntary international standard developed by ISO (International Organization for Standardization) that offers organizations the requisites for energy management systems. The standard is intended to be a tool for helping organizations to define energy strategies, setting short, mid and long term energy efficiency goals and implementing the consequent required actions for achieving them.
  • LEED – Leadership in Energy and Environmental Design: this is a voluntary certification system that is applicable to any type (commercial and residential) of buildings and that states the requisites for constructing eco-sustainable buildings, both in terms of energy and the environmental resource consumption used during the realization process.
  • CEN / UNI EN15232 “building energy performance - influence of automation, control and building management”: it was created to establish the impact of automation and control systems on a building’s energy performance, both current and future.
  • UNI CEI 11352:2014: establishes the general requisites and capacities (organizational, diagnostic, project, managerial, economic and financial) that an ESCO must have to offer energy efficiency services at its own clients’ premises. It also allocates a check list for verifying their capacity.

What support does ZEnergy software provides in energy efficiency management?
ZEnergy is an “intelligent” software package for monitoring and analyzing energy consumption. In this sense, it supports all the companies that must carry out energy audits and aids the updating to and observance of legislation, protocols and national and international standards.

ZEnergy is therefore an essential tool for having true energy efficiency, guaranteeing 15% saving on energy costs in the first year of use alone.

The four winning steps for exploiting the solution’s potential to the maximum:

Detection and recording of plant energy consumption

The system uses detection sensors (network analyzers, electrical meters, capacity gauges, etc) that are connected to data collection centers and read/remotely read company energy consumption.

Tools for reading energy consumption and environmental parameter trends in real time.

The consumption data reach the software in real time, allowing it to be monitored and analyzed, together with environmental parameters such as temperature, humidity, brightness, air quality etc.

Analysis and reporting functions for understanding data and identifying any sources for saving

Standard and customized reports are possible for the control and analysis of energy consumption and costs, for defining an energy balance and understanding the company areas with the highest energy impact.

Definition and monitoring of saving projects for upgrading interventions

The system supports technical/maintenance and energy management managers in analyzing energy management systems, highlighting any anomalies in the energy production systems and creating energy models for energy-saving purposes. 
It is also possible to analyze the energy bills and compare tariffs and different energy buying options, to save on and plan energy costs.

The ZEnergy system comprises the following hardware elements: 

  • Detection sensors for field data, comprising gauges (network analyzers, electrical meters, capacity and thermal gradient gauges) and detection sensors for environmental parameters.
  • Data collection centers that can interface with all specifically installed detection sensors that are set up to connect with the other devices already present on-site (e.g. Gas, water, light meters and Building Automation devices etc).

The detection sensors monitor consumption data for analytical reporting and send them to the centers via standard communication interfaces. The centers save the data on the non-volatile memory and make them available externally, sending them to a remote server. The server manages the data via the web and processes them thanks to specific algorithms, which allow ZEnergy to manage and analyze them for any type of need.
