Abstract: Openwork facades are used commonly in buildings in hot climates in the tropics. However, little is known about their performance regarding daylight sufficiency, glare probability and non-visual effects. In a hypothetical classroom, climate-based simulations were carried out in 3 cities in Colombia. Results were analysed considering people’s perception of light sufficiency and temporal variations in the directions of view. The results showed differences in daylighting performance due to the surface reflectance of the facades. When considering people's perception in the assessment, openwork facades with a high surface reflectance in the perforation have a great potential to improve daylighting performance of indoor environments.
