Aeration Control

Oxidation ditches are popularly used in rural areas and decentralized treatment facilities where energy deficiency is of concern. Aeration control technologies are well established for diffusion systems in order to improve energy efficiency, but there are still challenges in their application in oxidation ditches because surface aerators have unique characteristics with respect to oxygen transfer and energy consumption. In this paper, an integral energy model was proposed to include the energy, aeration, and fluidic effects of surface aerators, by which the energy for aeration of each aerator can be estimated using online data. Two types of rotating disks with different diameters (1800 mm and 1400 mm) were monitored in situ to estimate the model parameters. Furthermore, a feedforward–feedback loop control strategy was proposed using the concept of energy analysis and optimization. The simplified control system was implemented in a full-scale Orbal oxidation ditch, achieving an approximately 10% saving in full-process energy consumption. The cost–benefit analysis and carbon emission assessment confirmed the economic feasibility and environmental contribution of the control system. The energy model can help process designers and operators to better understand and optimally control the aeration process in oxidation ditches.

The supply of electricity is growing increasingly dependent on the weather as the share of renewable energies increases. Different measures can nevertheless maintain grid reliability and quality. These include the use of storage technologies, upgrades of the grid and options for responsiveness to supply and demand. This paper focuses on demand side management and the use of flexibility in production processes. First, the framework of Germany’s energy policy is presented and direct and indirect incentives for businesses to seek as well as to provide flexibility capabilities are highlighted. Converting this framework into a mixed integer program leads to multi-objective optimization. The challenge inherent to this method is realistically mapping the different objectives that affect business practices directly and indirectly in a variety of laws. An example is introduced to demonstrate the complexity of the model and examine the energy flexibility. Second, manufacturing companies’ energy efficiency is assessed under the frequently occurring conditions of heavily aggregated energy consumption data and of information with insufficient depth of detail to perform certain analyses, formulate actions or optimize processes. The findings obtained from the energy assessment and energy consumption projections are used to model the production system’s energy efficiency and thus facilitate optimization. Methods of data mining and machine learning are employed to project energy consumption. Aggregated energy consumption data and different production and environmental parameters are used to assess indirectly measured consumers and link projections of energy consumption with the production schedule.

Energy consumption in the world increases, so the measures in order to improve energy efficiency must be found. The aim of 2012/27/EU Energy Efficiency Directive targets is to decrease energy consumption for a final energy consumer by 1.5% every year, but there is no definition how these targets could be achieved by an individual member state. This article presents the analysis how these targets could be achieved by the means of individual heat metering by heat cost allocators for every flat thus decreasing an energy consumption for a final consumer. Statistical analysis of identical buildings with individual metering by heat cost allocators and without them is presented. Heat cost allocators do not decrease energy consumption by themselves, so this article presents a technical solution and a set of additional equipment, i.e. thermostatic valves, balance valves, hot water meters and remote data collection system that must be installed. The final results show that the targets of 2012/27/EU Energy Efficiency Directive in Lithuania can be reached, because the buildings with individual heat cost allocators consume about 20–30% less of heat energy. Pasaulyje energijos vartojimas auga, todėl turi būti rastos energetinio efektyvumo pagerinimo priemonės. 2012/27/ES Energijos Efektyvumo Direktyvos tikslas yra sumažinti galutinio energijos vartotojo energijos suvartojimą kasmet po 1,5 %, tačiau nėra nurodyta, kaip kiekviena valstybė narė šiuos tikslus galėtų įgyvendinti. Šis straipsnis pristato analizę, kaip šie tikslai galėtų būti pasiekti, kiekviename bute įrengiant individualios šilumos apskaitos šilumos daliklius, kad sumažėtų energijos vartojimas atskiruose butuose. Pateikta statistinė identiškų pastatų su šilumos dalikliais ir be jų analizė. Šiluminei energijai taupyti neužtenka vien tik šilumos daliklių, todėl straipsnyje pateiktas techninis sprendimas – būtinų įdiegti techninių priemonių paketas, kurį sudaro tokios priemonės: termostatiniai ventiliai, balansiniai ventiliai, karšto vandens skaitikliai, belaidė reguliaraus duomenų nuskaitymo sistema. Galutiniai analizės rezultatai rodo, kad 2012/27/ES Energijos Efektyvumo Direktyvos tikslai Lietuvoje gali būti pasiekti, nes pastatai su individualia šilumos apskaita ir įrengtais šilumos dalikliais vartoja apie 20–30 % mažiau šiluminės energijos nei pastatai be tokios apskaitos.

The article analyzes domestic and international experience in the field of energy efficiency and energy security. Thus, it was important to adopt the Law of Ukraine "On the Energy Efficiency of Buildings", which introduced mandatory certification of buildings by energy consumption classes. The study of sources on the issues of effective energy consumption showed that issues related to improving the energy efficiency of buildings and structures are acquiring special relevance; the use of foreign models to improve the energy efficiency of the housing stock. Specific organizational and economic measures are highlighted that will help improve the energy efficiency of the national economy. The Swedish experience of using a modern cost model for the full period of operation ("General Concept") is studied, which aims to assess the economic results of investments in measures to improve the energy efficiency of the housing stock. The main principles of the modern cost model of the full operation period and the criteria for determining the number of necessary energy efficiency measures are considered. Analyzed "hard" (physical condition of the building) and "soft" (user behavior) measures that provide for the integrated energy efficiency of the building. The stages of the analysis according to the cost model of the full operation period are considered. The typical for Sweden ranges of the duration of energy efficient measures and the requirements for the internal rate of return, which depends on the general economic situation in the country and the terms of the loan, have been investigated.  Based on the results of the energy audit of the ten-story building selected for the study and taking into account the experience of Sweden, a number of measures to improve energy efficiency are proposed and a calculation is given to ensure the energy efficiency of a residential building in Ukraine. Based on the results obtained, it can be concluded that there is a positive trend in this implementation. With the integrated use of all measures that will even allow you to save more, you can significantly improve the energy efficiency of the existing housing stock in Ukraine.

The requirements concerning the energy certification of buildings established in Directive 2002/91/EC of the European Parliament and of the Council of 16 December 2002, which was in turn modified by Directive 2010/31/EU of the European Parliament and of the Council, of 19 May 2010, regarding the energy efficiency of buildings, were transposed into Spanish legislation through Royal Decree 47/2007, dated January 19, through which a Basic Procedure for certification was approved of energy efficiency of new buildings, which was consolidated by Royal Decree 235/2013, of April 5, which approves the basic procedure for the certification of the energy efficiency of buildings. In said Royal Decree, it is established that existing buildings or units of buildings occupied by a public authority, must obtain an energy efficiency certificate and will have the obligation to display their energy efficiency label, when their total useful area exceeds 250 m2, and are usually frequented by the public. The Basic Procedure is established that must comply with the methodology for calculating the energy efficiency rating, considering those factors that have the greatest impact on their energy consumption, as well as the technical and administrative conditions for the energy efficiency certifications of the buildings. For this purpose, three software programs were promoted from the competent Ministry, one corresponding to the general option (LIDER-CALENER “HULC” unified tool) and two others corresponding to the simplified option (simplified procedures CE3 and CE3X), which allow the energy qualification to be carried out of buildings according to three types of buildings (residential, small and medium-sized tertiary, and large tertiary) that are increasing the requirements of the energy certification of the building depending on the type of the same. This study identifies the possible alternatives for improving energy efficiency over the initial qualification of the building, within a context of technical and economic feasibility, optimizing energy demand, reducing CO2 emissions and building energy consumption, being The study also compares the results obtained in the energy rating, between the general option and the simplified procedures, on an Andalusian health center in 1957, which corresponds to the typology of the Grand Tertiary building (GT).
