Retrofitting Strategy of Residential Buildings Based on Detailed Energy Monitoring Measurements in Hot Climate

Abstract

In this comprehensive study, a typical house underwent extensive monitoring over several years to measure direct deterministic consumption of each active system component. The indeterministic components including infiltration, air conditioner, fenestration and envelope performances were found through inverse sensitivity analysis. The data collected over the monitoring period revealed that the Energy Use Intensity (EUI) of the house amounted to 184 kWh/m2/year, for which the air-conditioning system accounted for approximately 80%. To reduce this demand, it is imperative to enhance the air tightness and thermal characteristics of the fenestration and envelope of the building. In addition, the air conditioner with higher performance must be promoted.
