This paper presents an energy performance assessment on an educational building in
Barranquilla, Colombia. The electricity consumption performance was assessed using the software
DesignBuilder for two different Air Conditioning (AC) systems. The current electricity intensity is
215.3 kWh/m2 -year and centralized AC systems with individual fan coils and a water chiller share
66% of the total consumption and lighting at 16%. The simulation of the AC technology change to
Variable Refrigerant Flow (VRF) resulted in an improvement of 38% in AC energy intensity with
88 kWh/m2 -year and significant savings in electricity consumption and life-cycle cost of AC systems
in buildings. Este artículo presenta una evaluación del desempeño energético en un edificio educativo en
Barranquilla, Colombia. El rendimiento del consumo de electricidad se evaluó mediante el software
DesignBuilder para dos sistemas de aire acondicionado (AC) diferentes. La intensidad actual de la electricidad es
215,3 kWh / m2-año y sistemas de aire acondicionado centralizados con fan coils individuales y un enfriador de agua compartido
66% del consumo total e iluminación al 16%. La simulación de la tecnología AC cambia a
El flujo de refrigerante variable (VRF) resultó en una mejora del 38% en la intensidad de energía de CA con
88 kWh / m2 al año y ahorros significativos en el consumo de electricidad y el costo del ciclo de vida de los sistemas de CA
en edificios.
