Estrategias para Mejorar la Eficiencia Energética en Edificios de servicios públicos, en una Zona Climática Calurosa y Húmeda: Caso de Estudio en Guayaquil, Ecuador

Abstract

Since 2010, there has been an approximate annual increase of 1% in CO2 emissions due to buildings. The reduction of energy consumption and consequently the mitigation of Greenhouse Gases are global goals due to the global issue of climate change. A key step in achieving these goals is to improve the energy performance of buildings, thereby reducing energy consumption and emissions generated by the built environment. In this regard, the present research focuses on identifying and estimating strategies to reduce energy consumption in buildings known as Community Police Units (UPCs) located in the city of Guayaquil, which corresponds to a very hot and humid climate zone. The study consists of statistical analysis of the historical energy performance of 43 buildings sharing the same architectural design. Additionally, the selection of a representative building was made for energy use monitoring and energy simulation. The results revealed a potential saving of 16 000 kWh per year by reducing the control temperature of the air conditioning system by 1°C and adjusting the on/off schedule. This is equivalent to 1 150 USD and 5 metric tons of CO2 emissions.
