For this, an environmental analysis on the production of CO2 has been applied to two scenarios of electricity generation for a residential building in Medellin city (Colombia). The first one refers to La Sierra thermo-electric plant located in La Sierra, municipality of Puerto Nare, in the Antioquiashire, which is the most efficient plant in Colombian thermal generation. The second comparison scenario refers to the annual operation of a micro-cogeneration facility, which satisfies the building's hot water and electrical energy needs. Using the capabilities of the TRNSYS v17® energy simulation software and the emission equations available in the public domain, the comparative environmental analysis is carried out between one and the other for the same load. The losses in electric transmission are assumed to be 10%. This analysis has shown a difference of more than 50% in emissions generation, with the main cause being the amount of fuel used, which for both cases is natural gas. On the other hand, this study shows the environmental advantages in the use of in-situ generators, decreasing transmission losses.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN El estudio realizado aquí busca determinar la ventaja que tiene el uso de instalaciones de generación eléctrica in-situ frente a generadoras convencionales, siendo evaluadas desde el punto de vista tecno-ambiental. Se ha aplicado un análisis de desempeño técnico y ambiental con respecto al consumo específico de combustible y de producción de CO2, respectivamente, aplicados a dos escenarios de generación eléctrica para un edificio residencial en la ciudad de Medellín (Colombia). El primero hace referencia a la termoeléctrica la Sierra la cual es la de mayor eficiencia en generación térmica de Colombia. El otro escenario de comparación hace referencia al funcionamiento anual de una instalación de micro-cogeneración, la cual satisface las necesidades de agua caliente y energía eléctrica del edificio. Con el uso de las capacidades del software de simulación energética TRNSYS v17® y de las ecuaciones de cálculo de emisiones disponibles en el dominio público, se lleva a cabo el análisis tecno-ambiental comparativo entre uno y otro para una misma carga. Las pérdidas de transmisión eléctrica son asumidas en un 10%. Este análisis ha mostrado una diferencia de más del 50% en generación de emisiones teniendo como condicionante principal la cantidad de combustible usado (gas natural), el cual se reduce en una misma proporción. Por otro lado, este estudio permite evidenciar las ventajas técnico- ambientales en el uso de generadores in-situ, haciendo menores las pérdidas por transmisión.]]></p></abstract>
