“…The single steps have been discussed in detail by the authors in previous papers , (Cesarotti et al, 2009), , (Andreassi et al, 2009). In this chapter the whole methodology and the importance of links and interconnections among the different phases and their role in reducing costs are highlighted.…”

“…However, the machines typically used in these systems have small thermal inertia, thus allowing quick load variation, and may be operated under partial load. As demonstrated by the authors in (Andreassi et al, 2009), the energy system model together with the energy consumption one may lead to an optimal management of the power plant thus reducing energy costs. This, again requires a detailed energy consumption profile and then an accurate data collection system.…”

“…The effective plant efficiency is largely determined by its control strategy (Onovwiona and Ugursal, 2006;Hawkes and Leach, 2007;Fabrizio et al, 2009;Andreassi et al, 2009;Chiappini et al, 2011;Facci et al, 2014a,b;Tribioli et al, 2016). Thereafter, we compare the performances of the different configurations assuming an optimized control strategy that is obtained through the methodology introduced in (Facci et al, 2014b), and further developed in (Facci et al, 2014c) and (Facci et al, 2014a).…”

“…The working conditions (i.e the control strategy and the environmental conditions) determine the effectiveness of an energy systems as much as the design performance of its components (Onovwiona and Ugursal, 2006;Hawkes and Leach, 2007;Fabrizio et al, 2009;Andreassi et al, 2009;Chiappini et al, 2011;Facci et al, 2014a,b;Tribioli et al, 2016). Therefore, implementing a proper control strategy is crucial to achieve the expected benefits from DG systems.…”

The optimal design of distributed generation systems is of foremost importance to reduce fossil fuel consumption and mitigate the environmental impact of human activities in urban areas. Moreover, an efficient and integrated control strategy is needed for each of the components of a distributed generation plant, in order to reach the expected economic and environmental performances.In this paper, the transition from natural gas to electricity-based heating is evaluated for residential applications, considering the interplay between photovoltaic electricity produced on site and the thermal energy storage, to grant the optimal management of heating devices. The energy demand of an apartment building, under different climatic conditions, is taken as a reference and four power plant solutions are assessed in terms of energy cost and pollution reduction potential, compared to a baseline plant configuration. The performance of each power plant is analyzed assuming an optimized control strategy, which is determined through a graph-based methodology that was previously developed and validated by the authors. Outcomes from our study show that, if heat pumps are used instead of natural gas boilers, energy costs can be reduced up to 41%, while CO 2 emissions can be reduced up to 73%, depending on the climatic conditions.Our results provide a sound basis for considering the larger penetration of photovoltaic plants as an effective solution towards cleaner and more efficient heating technologies for civil applications. The simultaneous utilization of heat pumps (as substitutes of boilers) and photovoltaic panels yields a positive synergy that nullifies the local pollution, drastically cuts the CO 2 emission, and guarantees the economical sustainability of the investment in renewable energy sources without subsidiary mechanisms.

“…In this context, Andreassi L. (2009) discusses that, even if policy is an important mean, it cannot be the only one and it is necessary to spread the knowledge on energy systems, energy saving options and energy use rationalization. It is important that the main energy users, as industries, realize that energy is not a fi xed operating cost and that saving energy is actually one of the most signifi cant ways to reduce costs, besides preserving the environment (Andreassi et al, 2009). After transport, the industry is a major consumer of energy in Europe (fi gure 1), with a share of 26%.…”

Energy Management Model - An Innovative Tool for Benchmarking the Energy Management System in Industrial Companies

2016

View full text Add to dashboard Cite

Energy management is becoming an important topic for companies around the world. It influences organizational and technical processes and behaviors in the company in order to reduce the operational total energy consumption, improve resource efficiency, implement legislative requirements, and improve their corporate image. ISO 50001 International Standard was introduced as a global standard for managing energy use through that provides the unified framework for energy management. This paper introduces and describes model methodology and innovative software tool for benchmarking the energy management system in industrial companies. The software is designed to illustrate the current energy management situation in the company, the estimation of target state and to identify the energy efficiency potentials. Using the benchmark methodology, the energy management is summarized in an assessment profile. The results can be used as a reference guide for Energy Managers or extern consultants to understand the requirements and to implement ISO Standard 50001 in their company. A case study of an Austrian foundry is empirically tested and presented in order to evaluate the efficiency of the developed model.
