We consider a typical garage door with a surface area of 10 m x 3 m (30 m²) and a thickness of 0.1 m. The door is made of steel with a thermal conductivity of 50 W/m-K and an emissivity of 0.6. We assume that the door is exposed to a constant solar radiation of 500 W/m² during the day and zero at night. The environmental temperature is set at 20°C.

Radiative cooling is a natural process where a surface loses heat by emitting infrared radiation into the atmosphere. This phenomenon can be harnessed to reduce the energy consumption of industrial facilities, particularly those with large surface areas such as garage doors. In this study, we investigate the potential of radiative cooling to mitigate the heat gain through garage doors in industrial settings. We analyze the thermal performance of a typical garage door and propose a radiative cooling strategy to reduce its surface temperature and heat transfer. Our results show that radiative cooling can significantly decrease the energy consumption of industrial facilities, especially during nighttime or periods of low solar radiation. usi de garaj radauti

For homeowners in Rădăuți, insulated garage doors (uși termopan or uși cu panou sandwich) have become the standard. An uninsulated metal sheet might suffice in milder climates, but in Bukovina, a non-insulated garage allows the cold to penetrate, potentially freezing pipes and making the adjacent living spaces unbearably cold. Consequently, local demand has shifted heavily toward sectional doors with high-density polyurethane foam insulation. These doors act as a thermal buffer, helping residents manage heating costs and protect their vehicles and stored goods from the biting winter chill. We consider a typical garage door with a
