dc.description.abstractThis study investigated two shoebox models representing a typical office space with an area of 20m2, one without window shading and one with a fixed louvered overhang. The study explored the impact of the louvered overhang with projection factor of 0.7 for an east, west and south-facing window on cooling load reduction and daylighting performance for office building retrofits in Accra, Ghana, and Miami, USA. The results showed that, in both Accra and Miami, the fixed louvered overhang achieved a reduction in window transmitted solar radiation of 22.7% - 27.3% for the Accra model and 26.3% - 30.2% for Miami. Consequently, total annual cooling load was reduced by 6% - 9% in Accra and 10% - 12% in Miami. In all cases, the louvered overhang improved the Useful Daylight Illuminance of the office space by 3.9% - 5.4% in Accra and 1.9% - 3.4% in Miami.en_US
