Air curtains have been widely used as a mean of reducing infiltration and associated energy
losses through building entrances. Since quantifying the infiltration rate through the …

Building entrance doors are a major source of air infiltration and energy loss in commercial
buildings. Previous studies have calculated entrance doors air infiltration and energy saving …

An air curtain installed at a building entrance acts as a barrier against infiltration/exfiltration
of airflow between the outdoor environment and the indoor space. Several factors may affect …

The efficiency of air curtain in reducing infiltration and associated energy usage is currently
evaluated statically by using an efficiency factor, η air, based on single steady/static …

Abstract ANSI/ASHRAE/IES Standard 90.1 requires vestibules to be installed in buildings in
climate zones 3 through 8 based on building energy simulations with a series of …

This study investigates the energy saving impact replacing vestibules with air curtain doors
(single doors fitted with air curtain units) has on energy usage of commercial buildings …

Air curtains have been widely used on building entrances as a barrier to reduce energy
losses due to infiltration/exfiltration while still permitting unobstructed passage of pedestrian …

Air curtains are widely used in various building types to reduce infiltration and associated
energy losses through building entrances. Quantifying the infiltration rate through a building …

Air infiltration through building entrance doors has been the focus of many studies due to the
significant effect infiltrated air has on the buildings' energy performance. Air infiltration …
