Revisión energética y análisis de las emisiones de CO2 en un edificio comercial con base en la norma NTE INEN-ISO 50001:2012 y la norma NTE INEN-ISO 14064-1:2010, respectivamente

Abstract

The purpose of this research work is to carry out an energy review of a commercial building and analysis of CO2 emissions applying the ISO 50001 and ISO 14064-1 standards, and to find opportunities for better energy performance. For the energy diagnosis, the information was extracted from the electricity consumption bills corresponding to the period from January 2018 to December 2019. A survey of the building's facilities was carried out to know the architectural and operating conditions of the building. Through the lifting of loads, the key points to collect energy consumption data were determined. And with the help of the Pareto diagram, it was identified that the largest energy consumers are given by the data center with 29%, followed by office equipment with 22% and the lighting system with 14%. As well as the values of the energy performance identifiers implemented 71.69 kWh / m2 year and 36.85 kg CO2 / m2 year. For the calculation of carbon emissions the methodology of the NTE INEN-ISO 14064-1: 2010 standard was applied, obtaining as results in Scope I (diesel generator) a total of 3.77 t CO2, and in Scope II ( electricity consumption) a total of 245 t CO2 in 2019. Finally, once with the results obtained, a series of measures are proposed aimed at improving energy performance without affecting the comfort and safety of the users of the building in question.
