Use Of Resources

Data centers are widely recognized for demanding many energy resources. The greater the computational demand, the greater the use of resources operating together. Consequently, the greater the heat, the greater the need for cooling power, and the greater the energy consumption. In this context, this article aims to report an industrial experience of achieving energy efficiency in a data center through a new layout proposal, reuse of previously existing resources, and air conditioning. We used the primary resource to adopt a cold corridor confinement, the increase of the raised floor’s height, and a better direction of the cold airflow for the aspiration at the servers’ entrance. We reused the three legacy refrigeration machines from the old data center, and no new ones were purchased. In addition to 346 existing devices, 80 new pieces of equipment were added (between servers and network assets) as a load to be cooled. Even with the increase in the amount of equipment, the implementations contributed to energy efficiency compared to the old data center, still reducing approximately 41% of the temperature and, consequently, energy-saving.

The Right

In all types of data center, keeping the right temperature with less cost and energy is one of important objective as energy saving is crucial in increased data driven industry. Energy saving is global focus for all industry. In Information technology, more than 60% of energy is utilized in data centers as it needs to be up and running. As per Avocent data center issue study, across globe more than 54% of data centers are in redesigning process to improve their efficiency and reduce operational cost and energy consumption. Data center managers and operators major challenge was how to maintain the temperature of servers with less power and energy. When the densities of data center energy nearing 5 kilowatts (kW) per cabinet, organizations are trying to find a way to manage the heat through latest technologies. Power usage per square can be reduced by incorporating liquid-cooling devices instead of increasing airflow volume. This is especially important in a data center with a typical under-floor cooling system. This research paper uses Rear-Door Heat eXchangers (RDHx) and cool logic solutions to reduce energy consumption. It gives result of implementation of Cold Logik and RDHx solution to Data center and proves that how it saves energy and power. Data center has optimized space, cooling, power and operational cost by implementing RDHx technology. This will enable to add more servers without increasing the space and reduce cooling and power cost. It also saves Data center space from heat dissipation from servers.

With the rapid development of data centers in smart cities, how to reduce energy consumption and how to raise economic benefits and network performance are becoming an important research subject. In particular, data center networks do not always run at full load, which leads to significant energy consumption. In this article, we focus on the energy-efficient routing problem in software-defined network–based data center networks. For the scenario of in-band control mode of software-defined data centers, we formulate the dual optimal objective of energy-saving and the load balancing between controllers. In order to cope with a large solution space, we design the deep Q-network-based energy-efficient routing algorithm to find the energy-efficient data paths for traffic flow and control paths for switches. The simulation result reveals that the deep Q-network-based energy-efficient routing algorithm only trains part of the states and gets a good energy-saving effect and load balancing in control plane. Compared with the solver and the CERA heuristic algorithm, energy-saving effect of the deep Q-network-based energy-efficient routing algorithm is almost the same as the heuristic algorithm; however, its calculation time is reduced a lot, especially in a large number of flow scenarios; and it is more flexible to design and resolve the multi-objective optimization problem.

Reduce Energy Consumption

In geographical areas with cold climates, large, massively constructed industrial and warehouse buildings and logistics complexes are large consumers of energy resources. The great height and large contained volumes of the premises, the presence of a significant number of doors, and building configurations that include many transport corridors all require the use of air-thermal curtains to increase the energy efficiency of the buildings’ heating, ventilating, and air-conditioning (HVAC) systems, which commonly produce several thousand kilowatts of thermal power. Optimization of air curtains can improve the microclimates of the premises, achieve savings in the initial construction costs, and also reduce energy consumption during operation by 10–20%.

Green Ict

Green ICT is a lot more than efficient air-conditioning of data centers and switching off monitors and desktop PCs. ICT has the ability to give rise to and continuously enable energy saving on a scale 50 to 100 times bigger by becoming the technology that detects and prevents process inefficiency of energy intensive supply chains. Energy efficiency that can only be sustainably achieved as a result of using ICT creatively is outlined in this chapter. The authors consider the optimization of supply chain as a crucial enabler of the overall effort of an organization to improve its environmental credentials. Therefore, undertaking the audits of an organization’s supply chains, and ensuring that the end result improves its efficiency is one way of limiting the carbon generated during its activities.

The article substantiates the necessity and relevance of the introduction of progressive energy efficiency systems at industrial enterprises. It is shown that in Ukraine in 2020 only 43.1% of energy resources are used efficiently, according to the data of the energy efficiency rating. In 2019, this figure was higher - 54%. The analysis of the use of energy resources in industry, services, agriculture and the housing sector in Ukraine, as well as in the countries of the European Union. The issues of organizing energy efficiency benchmarking for industrial enterprises of Ukraine are considered. The main attention is paid to an integrated approach, which consists in creating a regulatory framework and organizing information support during benchmarking. The experience of the EU countries in solving the problem of technical regulation of energy efficiency benchmarking and the possibility of its use in international entrepreneurship is considered. Only the main stages of energy saving benchmarking are considered in detail, which include: selection of a benchmark, comparison and assessment, positioning of the research object and determination of leaders and outsiders, grouping benchmarking partners by energy efficiency level, identification of the gap, identification of the causes of inefficient energy consumption, determination of the scale and nature of the problem. The introduction of an energy efficiency benchmarking system on a regular basis as a control and planning subsystem as part of an energy management system will make it possible to track changes in the energy efficiency indicators of the production system and its structural objects, the level of energy efficiency over time, negative trends and causes of their occurrence, to assess the effectiveness of adaptation of the best principles of efficient energy consumption in own conditions and the effectiveness of the implementation of energy-saving measures, which will contribute to the continuous improvement of the production system and its facilities.
