Energy Conservation Measures

This paper focuses on the thermal and energetic behavior of a building located in the Brazilian Amazon Region, a region climatically characterized by elevated temperatures and high humidity levels, where achieving adequate thermal comfort demands a high-energy consumption due to the use of air-conditioning systems. Therefore, different energy conservation measures (ECMs) need to be evaluated to reduce the thermal load for cooling. The use of a thermal insulation material on the west wall and on the roof, and a photovoltaic (PV) system integrated as an architectural element and adapted to the roof of the building are considered. The building is simulated with the software energyplus, with its thermal behavior and energy consumption analyzed for an entire year and for a chosen design day, defined with data measured by a weather station installed close to the building. According to the evaluations carried out, it is determined that the ECMs have a direct and major influence on the reduction of the thermal load for cooling, on the reduction of the effects caused by radiation with the shading on the eaves, and the reduction of the transmittance on the surfaces that were modified in the study. In terms of energy consumption and economic feasibility, the ECMs reach an annual energy saving percentage of 74% for the building chosen as the case study, and the solutions adopted provide the return of the financial investment, proving suitable for energy saving and economically viable for regions with similar climatic characteristics.

Energy Conservation Measures

Efficient energy use is critical for the success of any industrial facility since reduced energy consumption through energy conservation/saving programs can benefit not only consumers and utilities, but society in general as well. In particular, reduced energy consumption generally leads to reduced emissions of greenhouse gases and other air pollutants into the environment. It also helps reduce the operational costs in the facility. There is a strong need to take some energy saving measures in every plant/ facility. Although these may be quite diverse, some of these measures include thermal insulation, use of more efficient equipment, heat recovery systems, high efficiency lighting, changing the fuel, reducing the cost of compressed air, and enhancing productivity. In this study, some certain energy conservation measures are considered for assessing a packaging film manufacturing facility in Gaziantep, Turkey. Taking advantage of dry and hot climates of the city, cooling compressor inlet air by evaporative cooling technique is also assessed. Our investigation shows that there is a huge room for energy conservation measures. The total savings potential are expected to be 869,350 YTL (about $725,000) representing about 16% of the total energy consumption. The payback periods for the identified measures are justified. We believe that the results are typical rather than exceptional for the industrial sector in Turkey.

The City

Sustainable development of the country is possible by adapting various energy conservation measures. Energy conservation helps in using energy in effectivemanner. Application of advanced technology and improved operation and maintenance practices contributes towards energy conservation. Smart streetlight framework is an essential piece of the smart city, which represents 10-40% aggregate power utilization in the city. In this paper the energy audit report is presented for streetlights in the industry and also presented various energy conservation measures with the help of sensors and automation. It was observed that Passive Infra-red (PIR) sensor helps a lot in saving energy where movement of people is low.

The article discusses the conceptual provisions for assessing the effectiveness of the company’s energy saving. It clarifies the concept of “energy efficiency”, and the place of efficiency in the system of characteristics reflecting the quality of the company’s energy management. It is shown that the efficiency is advisable to be considered as a characteristic of the targeted implementation process of the company’s energy management of the relevant energy conservation measures. It reflects the degree of utilization of potential opportunity allocated for the implementation of these activities to achieve the company’s energy saving goals. That is, the efficiency is only one, although very important, aspect of assessing the quality of the company’s energy management. A general approach is proposed for the construction of performance indicators for the creation of models and methods of decision-making support in the process of planning energy saving measures. This approach is based on the requirements that the performance indicators should be measurable and, at the same time, reflect the goal in the name of which energy conservation measures are implemented in the company, accurately reflect the results of these measures, depending on the resources allocated for their implementation, and also consider the synergistic effects of their interaction.
