Low Efficiency

Energy resources are gradually scarce and expensive. Raised a gap between increasing demand and energy supply. Bridging gap of demand together with energy supply by increase energy supplies is a very costly decision. Moreover, in the industrial sector with the high cost of energy, the longer the competitiveness decreases. Energy costs in total production costs reduce the number of profits each year. The strategy to prevent these problems is by increasing the efficiency of industrial operations and equipment. Several stages of the efficiency process begin with identifying balance, energy-saving opportunities, and energy utilization. This stage is better known as an energy audit. The advanced stage of the energy audit helps identify potential energy conservation and encourages the industry to focus on efficiency and conservation and is supported by adequate financing. In the research strategy, the opportunity to save energy costs in oil boiler units is practical, sustainable and economically feasible. On the results of measurements and calculations obtained boiler efficiency of 53.67% where the factors that cause the low efficiency of this boiler are the high excess water by 17.32% and heat loss from dry exhaust gas by 42.03%. The solution is done by controlling excess air by regulating the air entering the combustion chamber. In this way, energy savings can be increased by 15%.

Abstract In the last 50 years, both the authorities and the majority of the citizens have understood the need to enforce measures to both preserve energy and reduce the costs of producing it. Nowadays, every developed country has correlated the profitability and the competitiveness of its industry with the efficient and sustainable use of energy and is therefore making conscious efforts to improve these areas. Any action program deemed to enhance energy efficiency has as main component the critical analysis of the energetic resources allocated to an activity in a given perimeter, also known as energy audit. This paper aims to develop a model of risk classification to be applied in planning and performing procedures during energy audit, which can allow a common framework to be developed in this area of audit. The stakeholders of the entity will also be offered a unitary perspective regarding the risks of the respective business, which can be helpful in their decision-making process. The research methodology of this paper consists of quantitative instruments, namely the statistical analysis of a database containing energy audit conclusions of companies in Europe. The indicators used will relate to energy savings, the number of measures implemented as a result of the audit, the percentage of energy saved from total consumption (energy efficiency) and the business line of the company. The novelty this framework will bring consists of the congruence created in the energy audit procedures of different practices and of the standardization and quality improvement in energy audit opinions. The approach of energy audits will therefore evolve towards a risk based one, rather than an analytical one. Also, we will explain the importance of energy savings for the profitability and the competitiveness of companies in the economy today, while facilitating a transparent communication with the stakeholders. This analysis is relevant especially given the fact that the cycle of 4 years after the directive of mandatory energy audit has been enforced ends with 2018 and a conclusion can be drawn before the new audit period starts in 2019.

Audit Activity

The purpose of this study is to analyze the potential for energy savings because the laundry industry consumes a lot of energy and water. If the laundry industries are not controlled, it will cause serious environmental and energy problems. The audit activity was divided into three stages. Pre-audit stage, the auditors were divided into groups with clear details of tasks and responsibilities, starting with conducting energy audits on the floor, analyzing statistical data, and process flow. Site audit stage; conduct an audit on the floor from the beginning to the end of the process, then collecting and confirming the statistical data for energy and production. Post-audit stage, complete the audit report that will be submitted or presented to the laundry management, which consists of; audit findings with loss or savings analysis, accompanied by recommendations for further improvement. The results show that there are many savings opportunities, especially by overcoming the energy wasted in the production process. Improvements can be made by overcoming energy waste and controlling energy consumption and production more efficiently, implementing renewable energy technology such as solar dryer and hybrid photovoltaic and thermal (PVT) collector, and then considering industrial revolution 4.0 with IoT and ICT.

Overall Performance

A large amount of the operating costs in a building is determined by the energy requirements of its air conditioning system. The demand for more energy efficient units desired by both manufacturers and the consumers results in a dire necessity to have air conditioning units that are more energy efficient than the existing ones. In order to achieve the abovementioned features, a tool must be designed to simulate the thermal behavior of the air conditioners. In this work, a mathematical model is developed for air conditioning units and coded into a computer program to estimate the overall performance, as indicated by the unit energy efficiency ratio (EER). The main objective is to maximize the unit EER by proposing modifications or enhancements in the existing unit and to study the economics of these modifications based on the measured terms such as the energy savings and the operating cost. Finally, the effect of the proposed design modifications on the economy and environment at the national level in Saudi Arabia is estimated and presented as an example.

This study indicated the role of energy auditor to identify the energy efficient projects. Three main types of audits are: Preliminary, Single Purpose, and Comprehensive. Selecting the appropriate type of audit for your facility saves you time and money. Each type is distinguished by the level of detail and analysis required to complete the audit. The less detailed the audit, the less accurate the estimates of project costs and energy savings. Depending on your organization’s contracting requirements, the consultant who will conduct the energy audit and prepare the technical report can be selected either by sole source or competitive bid. The cost of an audit can be determined through price negotiations or competitive bidding. In either case, you must inform the bidders of the scope of the audit and its minimum reporting and analytical requirements, such as those contained in the Energy Commission’s feasibility study guide. This is to ensure that you are getting audit costs for comparable work.

Ch Selection

In Wireless Sensor Networks (WSN) the energy of Sensor nodes is not certainly sufficient. In order to optimize the endurance of WSN, it is essential to minimize the utilization of energy. Head of group or Cluster Head (CH) is an eminent method to develop the endurance of WSN that aggregates the WSN with higher energy. CH for intra-cluster and inter-cluster communication becomes dependent. For complete, in WSN, the Energy level of CH extends its life of cluster. While evolving cluster algorithms, the complicated job is to identify the energy utilization amount of heterogeneous WSNs. Based on Chaotic Firefly Algorithm CH (CFACH) selection, the formulated work is named “Novel Distributed Entropy Energy-Efficient Clustering Algorithm”, in short, DEEEC for HWSNs. The formulated DEEEC Algorithm, which is a CH, has two main stages. In the first stage, the identification of temporary CHs along with its entropy value is found using the correlative measure of residual and original energy. Along with this, in the clustering algorithm, the rotating epoch and its entropy value must be predicted automatically by its sensor nodes. In the second stage, if any member in the cluster having larger residual energy, shall modify the temporary CHs in the direction of the deciding set. The target of the nodes with large energy has the probability to be CHs which is determined by the above two stages meant for CH selection. The MATLAB is required to simulate the DEEEC Algorithm. The simulated results of the formulated DEEEC Algorithm produce good results with respect to the energy and increased lifetime when it is correlated with the current traditional clustering protocols being used in the Heterogeneous WSNs.
