Experimental analysis of energy savings and hygrothermal conditions improvement by means of air curtains in stores with intensive pedestrian traffic.

Highlights: [•] Open stores have to match an important thermal load due to the infiltration air. [•] This situation is harder with intense pedestrian traffic and in warm humid climates. [•] Climatic separation and advanced hygrothermal control systems enables energy savings. [•] Modern air curtains can keep suitable indoor air temperature and humidity conditions. [•] Energy savings in commercial buildings with these systems exceeds 30%. [ABSTRACT FROM AUTHOR]
