Broiler facilities consume a lot of energy resulting in natural source depletion and greater greenhouse gas emissions. A way to assess the energy performance of a broiler facility is through an energy audit. In the present paper, an energy protocol for an energy audit is presented covering both phases of data collection and data elaboration. The operational rating phase is analytically and extendedly described while a complete mathematical model is proposed for the asset rating phase. The developed energy audit procedure was applied to poultry chambers located in lowland and mountainous areas of Epirus Greece for chambers of various sizes and technology levels. The energy intensity indices varied from 46 to 89 kWh/m2 of chamber area 0.25–0.48 kWh/kg of produced meat or 0.36–1.3 kWh/bird depending on the chamber technology level (insulation, automation, etc.) and the location where the unit was installed. The biggest energy consumer was heating followed by energy consumption for ventilation and cooling. An advanced technology level can improve energy performance by ~ 27%−31%. Proper insulation (4–7 cm) can offer a reduction of thermal energy consumption between 10 and 35%. In adequately insulated chambers, the basic heat losses are due to ventilation. Further energy savings can be achieved with more precise ventilation control. Automation can offer additional electrical energy saving for cooling and ventilation (15–20%). Energy-efficient lights can offer energy saving up to 5%. The use of photovoltaic (PV) technology is suggested mainly in areas where net-metering holds. The use of wind turbines is feasible only when adequate wind potential is available. Solar thermal energy is recommended in combination with a heat pump if the unit's heating and cooling systems use hot/cold water or air. Finally, the local production of biogas with anaerobic fermentation for producing thermal or electrical energy, or cogenerating both, is a choice that should be studied individually for each farm.

Most manufacturing and process industries require compressed air to such an extent that in Europe, for instance, about 10% of the total electrical energy consumption of industries is due to compressed air systems (CAS). However, energy efficiency in compressed air production and handling is often ignored or underestimated, mainly because of the lack of awareness about its energy consumption, caused by the absence of proper measurements on CAS in most industrial plants. Therefore, any effective energy saving intervention on generation, distribution and transformation of compressed air requires proper energy information management. In this paper we demonstrate the importance of monitoring and controlling energy performance in compressed air generation and use, to enable energy saving practices, to enhance the outcomes of energy management projects, and to obtain additional benefits for non-energy-related activities, such as operations, maintenance management and energy accounting. In particular, we propose a novel methodology based on measured data, and baseline definition through statistical modelling and control charts. The proposed methodology is tested on a real compressed air system of a pharmaceutical manufacturing plant in order to verify its effectiveness and applicability.

Cloud computing is a new emerging paradigm which delivers an infrastructure, platform and software as services in a pay-as-you-go model. However, with the development of cloud computing, the large-scale data centers consume huge amounts of electrical energy resulting in high operational costs and environment problem. Nevertheless, existing energy-saving algorithms based on live migration don’t consider the migration energy consumption, and most of which are designed for homogeneous cloud environment. In this paper, we take the first step to model energy consumption in heterogeneous cloud environment with migration energy consumption. Based on this energy model, we design energy-saving Best fit decreasing (ESBFD) algorithm and energy-saving first fit decreasing (ESFFD) algorithm. We further provide results of several experiments using traces from PlanetLab in CloudSim. The experiments show that the proposed algorithms can effectively reduce the energy consumption of data center in the heterogeneous cloud environment compared to existing algorithms like NEA, DVFS, ST (Single Threshold) and DT (Double Threshold).

Abstract In the hotel business, the use of energy is very important, especially in the use of electricity, the portion of usage and allocation of funds for its provision is the largest. It can be seen that equipment such as lights, elevators, refrigerators, laundry, heaters, pumps, to the air conditioning system are some of the dominant tools in operations in the hospitality world. The results of the initial energy audit and detailed audit at the Grand Clarion Hotel Makassar showed that the Energy Consumption Intensity (IKE) is still far from the standard, which is 300 kWh / m2 a year. The building uses the largest amount of electricity in the Grand Clarion Hotel Makassar in Building A, which is in the Guest Room area of the air conditioning unit. The results of the initial energy audit of Energy Consumption Intensity (IKE) electricity were 336.84 kWh / m2 year. Whereas based on the results of a detailed energy audit the electricity consumption intensity (IKE) of electricity is 395.51 kWh / m2 a year. Energy Saving Opportunities (PHE) in this energy audit is to evaluate the AC power in each room and recommend the replacement of lamp types. From the results of the IKE calculation after the application of PHE, it is found that the value is still quite high so that efforts to save must still be done.

The relevance of the research topic is that energy-saving is the key element of modern energy development in the country. In Kazakhstan, energy-saving, and improving the energy efficiency of agriculture is currently a priority task that will solve energy, environmental and economic problems. Without a solution to these problems, the country's development will inevitably hold back. The head of state in the field of energy conservation has set a goal to reduce the energy intensity of the gross domestic product by at least 25% by 2020, and annual energy-savings of 3.5% after 2020. Industry in rural areas consumes more than 70 % of all electricity. As part of the comprehensive plan, their energy audit was conducted 50/50 (50 % of the financing is the enterprises' funds, the remaining 50 % is the state budget). As a result of the energy audit, systematic measures were developed to reduce the energy intensity of the industry, including the electric power industry. Large unproductive losses of energy resources are in the private sector, in this connection, since 2019, the energy audit of JSC "Kazakhstan center for modernization and development of housing and communal services (housing and communal services)" is conducted on budget funds in the private sector. Energy conservation is one of the most important and strategic tasks of the country. Rapidly developing production requires additional energy costs. This is confirmed by the annual increase in energy tariffs. In turn, resources are not unlimited, and their irrational consumption will inevitably lead to not only economic but also to an environmental crisis.

Technological Intensity

This paper analyzes structural indicators of economic efficiency and energy intensity consumption as determinants of sustainable economic development for the selected 33 European countries. The correlation, regression and multivariate factor analyses are applied to test the associations between the selected structural variables of energy intensity consumption, economic efficiency, and the main driving forces behind these developments. Economic efficiency is positively associated with expenditures on research and development (R&D) and a greater technological intensity of exports, while at the same time the economic efficiency of R&D expenditures and technological intensity of exports reduce the energy intensity consumption of the economy. The results suggest that management strategies and policies directed towards R&D expenditures, human capital investments, and technologically intensive export oriented products are improving economic efficiency performance and contributing to energy saving sustainable economic development. The technological intensity of products reduces energy consumption, which is related to restructuring of energy intensive industries into more advanced and energy saving ones with higher value added per unit of product, but with lower energy consumption per unit of product. Santrauka Autoriai analizuoja struktūrinius ekonominio efektyvumo ir energijos vartojimo intensyvumo, kaip vienų iš pagrindinių subalansuotos plėtros kintamųjų, rodiklius. Tirti buvo pasirinktos 33 Europos valstybės. Autoriai, siekdami pagrįsti iškeltus teiginius, naudojo koreliacinę, regresinę analizę bei daugiakriterinius metodus galimoms ekonominio efektyvumo bei energijos vartojimo laipsnio (ir kitų, ne mažiau svarbių elementų) variacijoms nustatyti. Ekonominis efektyvumas labai dažnai asocijuojasi su tyrimais ir plėtra (R&D), eksportuojamomis aukštosiomis technologijomis. Remdamiesi atliktų tyrimų rezultatais autoriai siūlo nukreipti tiek politinius sprendimus, tiek valdymo strategijas į tyrimų ir plėtros (R&D) veiklas, investicijas į žmogiškuosius išteklius, technologinius sprendimus, nes visa tai galima susieti su subalansuotos plėtros koncepcija.
