Energy planning implementation in hotels. Case study in a hotel in the city of Barranquilla - Colombia

This article presents the results of energy planning in a hotel in the city of Barranquilla, Colombia, according to ISO 500001 standard methodology. The energy performance of the hotel was assessed, a low capacity for energy management was found and the main electricity consumers were identified and several energy-saving measures associated to bedrooms management and air conditioner operation were proposed and implemented reaching a 19,3 % of energy-saving. Also, a methodology to energy planning in hotels also was proposed and validated

Diseño del modelo económico energético para un sistema de alerta temprana (MEESAT) para los arroyos de Barranquilla
...
Pérez Flórez, Leyter José | 2015

The purpose of this paper is to perform an energy economic model that identifies in a clear, concise and detailed manner the consumption of each component installed on the system for early detection of streams in Barranquilla alerts, providing viable alternatives for achieving greater efficiency and sustainability of itself, within these alternatives are the use of renewable sources as the main power supply, to ensure that this project is completely independent of the conventional power grid, just as a feasibility study is performed on supply this case is not possible to supply the demand required for the early warning system using renewable sources; in this way is introduced the project a study of variables that must be considered when implementing energy supply by the grid operator Electricaribe S.A. E.S.P. For the development of this project aspects such as cultural, social, environmental and economic were analyzed to determine the caused on each impact, the various energy models implemented in the world and its impact on the places that were implemented were analyzed providing through this greater vision when defining the appropriate model to implement the early warning system. Based on the need that arises in the city of Barranquilla and considering that it is a single problem in the world is almost impossible to establish an energy model that matches all the requirements for this, for that reason and taking alternatively studying various energy models which include models such as: MARKAL, LEAP, bottom up, among others, will come to the determination that the most feasible to implement the early warning system should be a hybrid model that includes the most important features of each of the models presented herein. Based on this determination born as an alternative economic model ENERGY FOR Early Warning Systems - "MEESAT". MEESAT is an energy model that not only takes into account issues such as those mentioned above but it also adds an economic analysis and an analysis of consumption by projecting demand in case the system tends to expand and should add other elements, this model does not neglect safety due on SAT when commissioning of equipment, as does a study of reliability of the system taking into account issues such as maintenance, priority for the proper functioning of the equipment, one of the main features of this model is the study carried out for each device and component that integrates the alert system, performing an energy characterization to reach a consumption estimate and thus establish the total system demand.MEESAT equally integrates the analysis of short-circuit currents, voltage levels, connection diagrams, chargeability connection points all this in order to determine the feasibility of connection to conventional power grid in case of not having with a sufficient supply of energy from renewable sources. This model integrates all the requirements and provides guidelines to develop a reliable and safe consumer research to ensure sustainability, efficiency and good electrical performance of the SAT.

Research evolution on renewable energies resources from 2007 to 2017: a comparative study on solar, geothermal, wind and biomass energy
...
Valencia Ochoa, Guillermo | 2019

This article presents a bibliometric analysis of trends and the research state on the main renewable energies based on information obtained from the SCIE/SSCI database for the period 2007-2017. The analysis is aimed at solar energy, geothermal energy, wind energy and biomass energy source. The results generated from the bibliometric techniques used allowed to obtain the behavior of the publications production and the influence that different countries and universities have on this subject. From the 10,363 publications, the 87.5% are journal articles and the 98% are in English language. In addition, 49.03% of the publications corresponded to solar energy, 33.83% to wind energy, 12.77% to biomass and 4.37% to geothermal energy. In the 10 years analyzed, the United States has been the most influential country in this research area, presenting the largest volume of publications in each of the renewable energies source studied. The results of this paper provide to energy researchers a relevant overview of the tendencies and scope of the main renewable energies worldwide. In addition, to support scientific decision and prospective investment in research center, relevant data are presented on the countries producing these renewable energies and their relationship with the production of publications.

A Procedure For Criteria Selection In The Energy Planning Of Colombian Rural Areas
...
Robles Algarin, Carlos Arturo | 2018-06

This paper presents the process of selecting a set of criteria for use in energy planning processes using renewable energy sources in rural areas of Colombia. The implementation of renewable energies in the electrification programs of rural areas in Colombia has several obstacles, among which the inadequate selection of criteria to assess the relevance of projects is highlighted. From a bibliographic review, 33 criteria were identified and submitted to expert judgment with a questionnaire based on the Likert scale. For the selection process, the arithmetic mean and the level of significance were used as reference. After processing the results, 20 subcriteria were selected and grouped into five criteria: technical, economic, social, environmental and risk; which allow a comprehensive evaluation of energy planning projects.
