Inverse Modeling To Estimate The Effective Leakage Area In Buildings ✓ Most Recent

Infiltration plays a significant role in the energy consumption of buildings. Estimating infiltration rates can provide insights into building energy consumption patterns. Both Effective Leakage Area (ELA) and Air Change rate per Hour (ACH) can be used to describe the air infiltration rate in the building. This paper presents an approach using the ELA as the major parameter to model infiltration in existing buildings The conventional way to estimate the aggregated ELA value of a building is through a blower-door test, which is rather expensive in practice. This study introduces a lower cost alternative to estimate the ELA using inverse modeling approach .
