Streszczenie:

Quantifying subsurface velocity in the surf-zone beneath shoaling/breaking/broken waves is critical to accurately predict nearshore processes such as sediment transport [Hsu and Hanes, 2004]. The in-situ instruments designed to measure this velocity where waves break, such as velocimeters, routinely get buried, broken, or lost in the surf-zone. This limits our ability to collect field datasets of subsurface velocity in energetic wave conditions. To address this, we propose to build on known relationships that link subsurface velocity behavior to more easily observable surface signatures. Here, we collect the necessary surface and subsurface data to test the hypothesis that surf-zone surface measurements can predict subsurface velocity profiles extending to the bed.

Streszczenie:

Compound coastal flooding considers the joint impacts of marine and hydrologic interactions and has recently been identified as an international research priority. Along the US West Coast, winter storms often bring high marine water levels along with energetic waves and precipitation. Hydrodynamic models have been widely used to estimate flood impacts, including extreme estuarine water levels in compound events (e.g., riverine discharge-tide-storm surge interactions), and produced satisfactory results. However, few studies further consider overland flow routing and high-resolution flood mapping in highly urbanized, low-lying coastal areas. Here, an integrated Delft3D-FM based numerical modeling framework is used to explicitly resolve multi-pathway flood processes (i.e., high marine water levels, waves overtopping, precipitation) and infrastructure (e.g., seawalls, storm drains, artificial dunes).

It is proposed an analysis of the related variables with the energetic consumption in the process of concentrate of copper; specifically ball mills and SAG. The methodology considers the analysis of great volumes of data, which allows to identify the variables of interest (tonnage, temperature and power) to reach to an improvement plan in the energetic efficiency. The correct processing of the great volumen of data, previous imputation to the null data, not informed and out of range, coming from the milling process of copper, a decision support systems integrated, it allows to obtain clear and on line information for the decision making. As results it is establish that exist correlation between the energetic consumption of the Ball and SAG Mills, regarding the East, West temperature and winding. Nevertheless, it is not observed correlation between the energetic consumption of the Ball Mills and the SAG Mills, regarding to the tonnages of feed of SAG Mill. In consequence, From the experimental design, a similarity of behavior between two groups of different mills was determined in lines process . In addition, it was determined that there is a difference in energy consumption between the mills of the same group. This approach modifies the method presented in [1].

An important problem in our world is that humanity’s energy consumption is constantly rising. Therefore, nowadays there is an increasing emphasis on the problem of reusability and efficient energy management. The present paper studies the energy sustainability of systems by developing a unique test model. Using this test model, the theoretical problems of closed systems are investigated. With a theoretical experiment, the temporal motion of rigid systems is monitored and the behavior of flexible systems is analyzed. Finally, the study of the energy interaction of the general system and its environment shows the basic condition for the system’s overall sustainability.

Coastal circulations are basic information when considering sediment transport and water quality in the oceanic environment, particularly the macro-vortices dynamics which greatly affected the mass transfer and extended the residence time (Hasegawa et al., 2009). Large-scale macro-vortices could be formed in the lee or around natural obstacles such as islands and headlands during the interaction between geographical features and coastal circulations induced by tides and winds. Pearl River is the second largest river in China considering discharge, delivering 3.26 × 1011 m3 freshwater every year into the South China Sea (SCS) through eight outlets (Wu et al., 2016). Hong Kong (HK) is located downstream of the Pearl River Estuary (PRE), acting as a bridge between the PRE and the SCS, as shown in Figure 1. HK possesses more than 200 islands as well as narrow channels and complex coastlines, which have a great impact on shaping local flow structures. In addition, prevailing southwest winds blow during the summer, while stronger northeast winds gust during the winter. Embracing tides from the SCS and river discharge from the PRE, HK waters is an energetic and interesting area and worth a detailed investigation.

Abstract. The study examined variation in energetic-efficiency profiles among production systems and cow parities. Further, the correlation between cows' body condition score (BCS) and energetic efficiency over the lactation period was determined. Biological efficiency was defined using four measures of production efficiency and two measures of energetic efficiency. The following were measures of energetic efficiency: the net energy intake required to produce 1 kg milk solids (NEin / MS) and the proportion of net energy utilized for milk production after accounting for maintenance (NElact / (NEin- NEm)). Seven years of data were gathered from a total of 595 Holstein-Friesian cows in a long-term genetics × feeding–management interaction project. Two feeding regimes – High forage (HF) and Low forage (LF) – were applied to each of two genetic lines (Control (C) and Select (S)), giving four dairy production systems: Low Forage Control (LFC), Low Forage Select (LFS), High Forage Control (HFC) and High Forage Select (HFS). LFS was the most efficient system using all measures. Variation in the rate and scale of change at which the cows' energetic efficiency declined over lactation was significantly different (P < 0.001) amongst different dairy production systems and parities. Loss of efficiency over the lactation period was lower in Select cows than in Control cows and increased with parity. The trajectory of energetic-efficiency profiles was influenced by cow genetic line, and yet the level of the efficiency profile was influenced by the feeding regime. There was a strong relationship between BCS and energetic efficiency. Continued in situ monitoring of cows' biological efficiency may enable optimal management of dairy systems.

Improving the performance of composite energetic materials comprised of a solid metal fuel and a source of oxidizer (known as thermites) has long been pursued as thermites for pyrolant flares and rocket propellants. The performance of thermites, involving aluminum as the fuel, can be dramatically improved by utilizing nanometer-sized aluminum particles (nAl) leading to vastly higher reaction velocities, owing to the high surface area of nAl. Despite the benefits of the increased surface area, there are still several problems inherent to nanoscale reactants including particle aggregation, and higher viscosity composited materials. The higher viscosity of nAl composites is cumbersome for processing with inert polymer binder formulations, especially at the high mass loadings of metal fuel necessary for industry standards. In order to improve the viscosity of high mass loaded nAl energetics, the surface of the nAl was passivated with covalently bound monolayers of perfluorinated carboxylic acids (PFCAs) utilizing a novel fluorinated solvent washing technique. This work also details the quantitative binding of these monolayers using infrared spectroscopy, in addition to the energetic output from calorimetric and thermogravimetric analysis.

The behavior of the energetic expense is fundamentally analyzed, mainly of the electric system and the support energetic systems that determine the conformation of the productions destined for the irrigation systems. Proposals are made that can contribute to diminishing the production costs in the productive entity and that can contribute to a decrease in the cost of obtaining the agricultural product.</p>

Seasonal energetic challenges may constrain an animal's ability to respond to changing individual and environmental conditions. Here, we investigated variation in heart rate, a well-established proxy for metabolic rate, in Svalbard reindeer ( Rangifer tarandus platyrhynchus ), a species with strong seasonal changes in foraging and metabolic activity. In 19 adult females, we recorded heart rate, subcutaneous temperature and activity using biologgers. Mean heart rate more than doubled from winter to summer. Typical drivers of energy expenditure, such as reproduction and activity, explained a relatively limited amount of variation (2–6% in winter and 16–24% in summer) compared to seasonality, which explained 75% of annual variation in heart rate. The relationship between heart rate and subcutaneous temperature depended on individual state via body mass, age and reproductive status, and the results suggested that peripheral heterothermy is an important pathway of energy management in both winter and summer. While the seasonal plasticity in energetics makes Svalbard reindeer well-adapted to their highly seasonal environment, intraseasonal constraints on modulation of their heart rate may limit their ability to respond to severe environmental change. This study emphasizes the importance of encompassing individual state and seasonal context when studying energetics in free-living animals. This article is part of the theme issue ‘Measuring physiology in free-living animals (Part II)’.

Paese. Oggi questo non č piů vero: non č piů possibile trattare di energia e ambiente senza occuparsi di industria e sviluppo. Tre eventi hanno modificato drasticamente la situazione: l'ingresso dell'Italia nell'Euro nel 1999, l'ingresso della Cina nella World Trade Organization (WTO) nel 2001, l'ampliamento dell'UE da 15 a 25 Paesi nel 2004, divenuti poi 27 nel 2007. In questo mutato contesto occorre una "Strategia energetica" (o di ogni altro strumento programmatico) č quindi quella di fornire indicazioni ai cittadini, ma soprattutto alle imprese, non solo del settore energetico, sulle iniziative che lo Stato intende assumere e sulle conseguenze, in termini di disponibilitŕ, di prezzi, di impatto sull'ambiente, che da esse potranno derivare. L'Italia non č ricca di risorse energetiche fossili; questa č una ragione in piů perché sia ricca di mercati energetici liberi, competitivi e trasparenti, governati da Autoritŕ forti e indipendenti che inducano lo sviluppo efficiente di infrastrutture materiali ed immateriali per il trasporto, lo stoccaggio e le negoziazioni di prodotti energetici e di CO2 .

This paper presents a method to support the development of energy management concepts for machine and plant construction. The energy management concepts are required to put the plant components into an energy saving mode during unproductive phases. These concepts then have to be implemented in the control software. Different dependencies in the production and process flow have to be considered when developing the concepts. Due to the complexity of production plants, a supporting simulation tool is planned to be implemented. With the aid of this tool, different energy management concepts and their derived control software can already be validated virtually in the planning and development phase. This presents an energetic extension of the so-called virtual commissioning concept. Conventional virtual commissioning involves only the process operation functionality in a virtual simulation model of the plant. Now, however, energetic functionalities are assigned to the different model components. Thus, a simulation of the energy consumption in different operation modes can be created for each component. Energy management concepts can only be developed if the components’ energy consumption is known in the different scenarios.

One of the main objectives in the field of waste management today is the implementation of waste-to-energy concept, because it decreases the amount of municipal solid waste landfilled and economizes the traditional hydrocarbon fuels. One of the main objectives of this study was to assess the global energetic potential of municipal solid waste and its potential contribution in energy balance. This evaluation was based on the analysis of main municipal solid waste properties such as component and chemical compositions, and heating value. The comparison of municipal solid waste properties and energetic potential with those for traditional solid fuels was also discussed. For comparison, the biomass samples and coals collected from Russian coal basins were considered. Study of municipal solid waste properties showed that municipal solid waste represents a well-flammable fuel with high carbon content (up to 50–60% for dry ash-free basis), and relatively high O/C atomic ratio. Total world energetic potential of municipal solid waste was estimated as 20 billion GJ that is 12.6% from energetic potential of coal mined. It was shown that by municipal solid waste incineration it is possible to produce 800 billion kWh of electrical energy that is about 3.5% of total world electricity generation. It was shown that in 2035 energetic potential of municipal solid waste may share up to 21.7% from energetic potential of coal. Executed estimations confirmed the urgency of municipal solid waste waste-to-energy implementation.

Waste from sustainable management activities in Amazonia can be an important source of biomass for energy generation. This study aimed to investigate the production and characteristics of pellets manufactured from residual biomass of the species Dinizia excelsa, Parkia spp., and Licania canescens. The pellets were produced separately by species in a laboratory pelletizer with a production capacity of 30 kg h-1 and a matrix diameter of 6 mm. A total of 1.5 kg of homogeneous pellets was produced for each type of biomass. The pellets were evaluated according to their physical and energetic properties. The physical and energetic properties varied between the waste analyzed (4884 kcal kg-1 for D. excelsa and 4650 kcal kg-1 for Parkia spp.). Greater emphasis should be placed on pellets produced with 100DE, which presented higher values of fixed carbon (20.7%), bulk density (692.55 kg m-3) and low ash content (0.30%).

In the future, an additional potential of control reserve as well as storage capacities will be required to compensate fluctuating renewable energy availability. The operation of energy systems will change and flexibility in energy generation and consumption will rise to a valuable asset. Wastewater treatment plants (WWTPs) are capable of providing the flexibility needed, not only with their energy generators but also in terms of their energy consuming aggregates on the plant. To meet challenges of the future in regard to energy purchase and to participate in and contribute to such a volatile energy market, WWTPs have to reveal their energetic potential as a flexible service provider. Based on the evaluated literature and a detailed analysis of aggregates on a pilot WWTP an aggregate management has been developed to shift loads and provide a procedure to identify usable aggregates, characteristic values and control parameters to ensure effluent quality. The results show that WWTPs have a significant potential to provide energetic flexibility. Even for vulnerable components such as aeration systems, load-shifting is possible with appropriate control parameters and reasonable time slots without endangering system functionality.

The coal-producing territories in the world are facing the production of renewable energy in their thermal systems. The production of biocoal has emerged as one of the most promising thermo-energetic conversion technologies, intended as an alternative fuel to coal. The aim of this research is to assess how the model of biomass to biocoal conversion in mining areas is applied for thermal systems engineering. The Central Asturian Coal Basin (CACB; Spain) is the study area. The methodology used allows for the analysis of the resource as well as the thermo-energetic conversion and the management of the bioenergy throughout the different phases in a process of analytical hierarchy. This is carried out using a multiphase mathematical algorithm based on the availability of resources, the thermo-energetic conversion, and the energy management in the area of study. Based on the working conditions, this research highlights the potential of forest biomass as a raw material for biocoal production as well as for electrical and thermal purposes. The selected node operates through the bioenergy-match mode, which has yielded outputs of 23 MWe and 172 MWth, respectively.

This essay examines the role of Anglo Protestant missions in the Persian Gulf in racializing “the Moslem world” for the emergent white world order at the beginning of the 20th century. More specifically, I consider the way Protestant missionaries extracted knowledge about Islam, racializing “the Moslem world” as a civilizational “unit” devoid of energetic life—and therefore incompatible with the modern world—even as they simultaneously mediated the rise of oil extraction along the Persian Gulf in that same period. Extraction was not only evident in the material relations of empire, but also in the way Protestant missionary discourse shaped “the Muslim world” into a racial unit in need of management and optimization. I consider two energetic grammars used by Protestant missionaries to signify the changes occurring in “the Moslem World”, namely, Samuel Zwemer’s use of “disintegration” and Basil Mathews use of “ferment”. I argue that it was in these material and discursive entanglements of oil extraction where knowledge about Islam became an important tool of European colonial governance, and where energetic grammars of religion became critical to the biopolitical production and management of racialized Muslim populations.

Fisheries modify prey availability for marine predators by extracting resources but also by providing them with new feeding opportunities. Among these, depredation, which occurs when predators feed on fish caught on fishing gear, is a behavior developed by many species as a way to acquire food through limited foraging effort. However, the extent to which depredated resources from fisheries contribute to the energetic requirements and affect the demography of depredating individuals is unknown. We investigated the contribution of Patagonian toothfish Dissostichus eleginoides depredated on longlines to the energetic requirements of killer whales Orcinus orca around the Crozet Islands (southern Indian Ocean) over the period 2007-2018. Our results indicate that during days when depredation occurred, depredating individuals fulfilled on average 94.1% of their daily energetic requirements with depredated toothfish. However, the contribution varied from 1.2 to 13.3% of the monthly energetic requirements and from 2.4 to 8.8% of the yearly energetic requirements of the total population. Together, these findings suggest that intake of depredated toothfish can be substantial at a fine scale (daily and individually), potentially leading to temporary provisioning effects and changes in predation pressures. These effects become minor (<10%), however, when considering the full population over a whole year. The contribution of depredated fish to the annual energetic requirements of the population has increased in recent years, likely due to larger fishing quotas and greater opportunities for whales to depredate, which stresses the importance of accounting for depredation in ecosystem-based management of fishing activity.

Most publications in management can be described as «energetic» presenting orientation to certain ideals, that even hardcore optimists believes that will never come true. So it is best to refer to actual practice and see what stirs people to operate normally. This original article describes the essence of terminator management, which in practice is, first of all, as the art of destruction of competent employees.

Potential areas for tidal stream energy development are conventionally selected on the basis of resource assessments. For all the importance of the resource, there are other elements (technological, economic, spatial, etc.) that must be taken into account in this selection. The objective of the present work is to develop a new methodology to select tidal stream hotspots accounting for all these relevant elements, and to apply it to a case study, showing in the process how the potential for tidal energy development can be fundamentally altered by technological, economic and spatial constraints. The case study is conducted in the Bristol Channel and Severn Estuary (UK), one of the regions with the largest tidal resource in the world. First, the most energetic areas are identified by means of a hydrodynamics model, calibrated and validated with field data. Second, the method calculates the energy that can be harnessed in these areas by means of a geospatial Matlab-based program designed ad hoc, and on the basis of the power curve and dimensions of a specific tidal turbine. Third, the spatial distribution of the levelised cost of energy (LCOE) is calculated, and a number of locations are selected as potential tidal sites. The fourth element in the approach is the consideration of restrictions due to overlap with other marine uses, such as shipping. As a result, potential conflict-free areas for tidal stream energy exploitation at an economical cost are identified. Thus, the case study illustrates this holistic approach to selecting tidal stream sites and the importance of elements other than the resource, which â€“ for all its relevance â€“ is shown to not guarantee by itself the potential for tidal stream energy development.

Now-a-days all documents are in a digital format as well as everyone need to maintain their data in electronic mode with the help of cloud servers. A cloud server provides lots of facilities to users such as remote data maintenance, huge data handling and so on. But in the case of security many cloud servers are providing probabilistic results alone. So, that a new cloud server data maintenance scheme is required to provide a high-level data security to the cloud system in an efficient manner. This paper introduces a new crypto-approach called Novel Hybrid Encryption Mode (NHEM), in which this algorithm integrates several latest approaches of crypto logics into it and provides a top-end security level to the cloud data. This NHEM is derived from the base factors of two cryptographic algorithms called Advanced Encryption Standard with 512-bit size of key frequency with Message Digest (MD5) algorithm. By using the integration of these two powerful approaches, a novel approach called NHEM is designed and it provides a huge support to preserve security on cloud medium. The cloud data needs to be protected from unwanted threats and intruders by means of raising an interruption attacks on server. The proposed approach of Novel Hybrid Encryption Mode concentrates more on access control logics and the crypto norms with respect to privacy measures. In this paper, the proposed scheme assures the data is too robust and no one can attack the data without proper credentials as well as the outcome proofs are clearly given on the resulting unit of this paper. The Advanced Encryption Standard algorithm is a well-known and powerful crypto scheme and the MD5 algorithm is also considered to be the unique unidirectional algorithm to provide security level in energetic manner. These two algorithms are combined together with the bit frequency of 512 to achieve the highest accuracy levels in data security over cloud environment as well as the resulting portion clearly illustrates that with proper graphical outcome.

Fitness facilities characteristically place an emphasis on the health and wellness of their occupants. Very loud amplified speech and music in group fitness rooms creates energetic spaces at the expense of the health and wellness of participants' hearing. The authors measured spectral sound pressure levels from fitness programs and occupants in over 20 group fitness classes (cycling, dance, strength training, and yoga) at facilities throughout the United States. Measurements occurred over durations varying from 10 minutes to a full hour. Variables considered include class type and the athletic club where the classroom is located. This paper discusses the overall findings from these noise surveys with an emphasis on noise exposure and statistical levels. This paper also includes a discussion of noise management and recommendations for best management practices to help achieve energetic spaces that are protective of hearing health and wellness.

The problem of enrichment of aluminum ores is due to the fact that bauxite-forming minerals have similar density, dispersed character and subtle intergrowth. Therefore, the development and improvement of methods for the enrichment and processing of bauxite continue. The work shows the effect of physical and chemical factors on iron minerals with the goal of transforming them into magnetite, to increase the magnetic phase. Influence of various kinds of energetic influences on bauxite raw materials and red mud is established, under which the magnetic properties and phase composition change, the concentrations of certain minerals change.

Energy supply represents not only the energetic and ecological undertaking factor of tourist economy bearers, but the factor of profitability and competitiveness within the foreign tourist market as well. Lower energy costs form the prerequisites for higher profit accomplishments, as well as better market price competitiveness. Instead of exploiting natural resources, tourism should make the most of them, which brings into relief the directing of tourist economy subjects towards the use of restorable energy sources, particularly solar and wind energy. In spite of favourable climate features of Croatia, expressed in terms of insulation and windstrength, the restorable energy sources are still used rather insignificantly. Some positive moves in such a trend are noticeable on the island of Pag and in the town of Sibenik, where the electric energy is obtained in wind power-plants. In accordance with the concept of sustainable development of tourism, both solar energy and wind-mill energy should represent the skeleton for the energetic supply of the Croatian tourist coastline in the future. And only then, with the right amount of energy and without dependence on the world energetic markets, Croatia can develop its own healthy economic and tourist future.

Energetic resilience is seen as one of the most prominent fields of investigation in the upcoming years. The increasing efficiency of urban systems depends on the conversion of energetic production of buildings, and therefore, from the capacity of urban systems to be more rational in the use of renewable resources. Nevertheless, the integration of the energetic regulation into the ordinary urban planning documents is far from being reached in most of planning processes. In Italy, mainstreaming energetic resilience in ordinary land use planning appears particularly challenging, even in those Local Administrations that tried to implement the national legislation into Local Building Regulation. In this work, an empirical methodology to provide an overall assessment of the solar production capacity has been applied to selected indicators of urban morphology among the different land use parcel-zones, while implementing a geographic information system-based approach to the city of Moncalieri, Turin (Italy). Results demonstrate that, without exception, the current minimum energy levels required by law are generally much lower than the effective potential solar energy production that each land use parcel-zone could effectively produce. We concluded that local planning processes should update their land use plans to reach environmental sustainability targets, while at the same time the energetic resilience should be mainstreamed in urban planning by an in-depth analysis of the effective morphological constraints. These aspects may also represent a contribution to the international debates on energetic resilience and on the progressive inclusion of energy subjects in the land use planning process.

The influence of season and management system on the productivity of Friesian cows in a Mediterranean climate was assessed. Intakes of food and water and milk yields were measured in 154 cows over 2·5 years while intensively managed in yards giving access to shelter (free stalls) or that were fully exposed to solar radiation (open lots). Food quality was also monitored to permit estimates of the efficiency of utilization of metabolizable energy for milk production over fortnightly periods.The highest milk yields and energetic efficiencies were recorded during spring. Energy intakes were highest but energetic efficiencies were lowest during winter. Cows consumed the least food during summer and autumn and drank the most water during summer. The only significant effect of management system was for water intake, which was higher in the open lots than in the free stalls. There was evidence of heat stress in summer and cold stress in winter, but there appeared to be little benefit with milk yields through the provision of shelter.

The subject matter of this paper is the functioning of a highly effective waste management system. Assumptions of the Energy Recovery Waste Processing (ERWP) model, being a universal solution for towns and regions irrespective of their population, are presented here. The result of simulations illustrating the energetic potential of municipal waste stored and processed in biological and physicochemical processes are also presented. Calculations were performed for the municipality of Koszalin (Poland), with a population of 106,000. Mixed household and commercial waste, organic waste, waste from selective collection and sewage sludge from a municipal wastewater treatment plant were considered in the waste mass balance. Empirical equations and unit coefficients describing the energetic efficiency of particular processes originating from the author’s own research work as well as from the results available from the scientific literature were used in the calculations. The developed ERWP model is based on the functioning of four objects constituting a comprehensive technical infrastructure, i.e., biological stabilisation in air condition (BSAC), mechanical treatment plant (MTP), cogeneration system plant (CSP) and gas production plant (GPP) where two independent modules operate, namely, dry/wet methane fermentation (DMF and WMF). Each day, this system generates highly energetic refuse-derived fuel (RDF) for combustion in amounts of 82.2 t for CSP and 127.3 t for GPP, generating 5519 m3 of gas/d. The value of the energy contained in such generated gas and in waste making up an alternative fuel is 1027.4 GJ, which is equivalent to 285.4 MWh. It should be noted that the creation of a waste management system based on the ERWP model assumptions fulfills the criteria of energetic recycling and allows for recovery of energy in the form of gas and heat equivalent to 79,917.6 MWh/a, i.e., 754 kWh/inhabitant/a.

Ecology is strongly related to the quality of energy management and to limiting the negative impact of the technosphere on the environment. This work refers to the analysis of energy quality and power balances in different, due to the specificity of functioning (used electrical equipment), business facilities. The research was carried out for supply networks: in the bank building, in the IT laboratory and in the office and warehouse facility. The measurements of currents, voltages, active, reactive and apparent power in individual phases of power supply system as well as distortions (higher harmonics) of currents and voltages were carried out. The research was carried out to identify irregularities in the networks and to indicate ways to limit the effects of electromagnetic disturbances (mainly higher harmonics) as well as achieve improvements in energy efficiency and ecology in the operation of these facilities.

As various political initiatives have set goals to reach net-zero emissions by the mid-21st century, forests will play an important role as a carbon sink for sequestering unavoidable emissions. Forest management can take two approaches by either decreasing harvest and enlarging the forest carbon stock or increasing harvest to increase carbon uptake and create harvested wood products (HWPs). Currently, these two management options seem at odds with seemingly conflicting policy directives being written. We used the BEKLIFUH model to assess six management scenarios based on carbon offset potential taking into consideration forest carbon, HWPs and the material and energetic substitution effects. The results show that while conservation leads to a higher above-ground carbon pool, including HWPs, material and energetic substitution leads to more overall carbon offsets for management scenarios with more timber harvesting. With compromise being possible by selectively conserving old growth forests with a high biodiversity value. In conclusion, if the forest sector decouples GHG reporting from forest management and includes all the secondary effects of timber harvest, this new approach can lead to a different cost–benefit analysis for the choice between harvest vs. conservation. This could result in a paradigm shift to a future where biodiversity and carbon neutrality can coexist.

Streszczenie:

The improvement of the energetic behavior of buildings has turned into a major issue due to the high level of energy consumption. In this context, the building is represented as a dynamical system and a system of data acquisition is developed, which allows the measurement of environmental and energetic parameters, so as to describe the behavior of the building interacting with its direct environment. Research related to energy management can be divided into two categories: predictive control (anticipative) and adaptive control (reactive). A new building energy management system (BEMS) which is the chosen system to validate, treats a long-term anticipative control and introduces a reactive control that adds another level of intelligence to the BEMS.The main goal of this paper is to propose a model using the formalism DEVS to describe and simulate the BEMS. Our motivation is explained by the fact that DEVS is a tool for modeling of discrete event systems and it divides the overall system into subsystems in order to facilitate the achievement which is consistent with the characteristics of multilayer architecture of the chosen system.
