Reusing shipping containers for residential purposes offers a promising approach to address global energy consumption challenges from economic and environmental perspectives. This study parametrically designed hybrid louver shadings by combining fixed vertical triangular slats with variable-depth horizontal rectangular slats

offering a novel approach to shading prefabricated buildings. The energy consumption

daylighting performance

and visual comfort were assessed for various shading configurations. Results indicated that implementing the proposed hybrid louvers

featuring fixed vertical triangular slats and variable-depth horizontal rectangular slats

significantly reduced Energy Use Intensity (EUI) to 133.95 kWh/m

. Moreover

Useful daylight illuminance (UDI)

Daylight Autonomy (DA)

and Glare Autonomy (GA) values improved to 95.38%

89.97%

and 91.16%

respectively. The study highlighted the potential of the proposed shading system to significantly reduce overall energy consumption across various ASHRAE climate zones

including Miami (1A)

Guangzhou (2A)

Melbourne (3C)

Esperance (3C)

San Diego (3A)

and Milan (4A). Notably

energy reductions of up to 50.2% were projected for climates such as Miami (1A) and San Diego (3A). Furthermore

container buildings in warm climate zones exhibited a significantly lower EUI range of 76.58 to 91.95 kWh/m². This study underscores the transformative po

tential of hybrid louver systems in promoting the widespread adoption of sustainable residential architecture

contributing to global sustainability efforts.
