Abstract Large reflective facades in buildings can cause severe visual discomfort due to the reflection of sunlight falling on buildings surfaces. These intense reflections can cause a intolerable glare and contribute to overheating the interior of surrounding buildings. An example of reflective building materials causing glare is experienced in Dallas, Texas, where a residential tower, which was fitted with a fully glazed faade, has caused intense specular reflections into the Nasher sculpture museum. The problem has caused glare and overheating of the interior spaces in the museum, thus leading to the damage and deterioration of the sculptures on display. In order to examine the negative impact of the Museum Towers reflective faade on the visual comfort inside the Nasher museum, glare simulations are carried out at different times of the year. Additionally, to examine a possible solution to the glare problem, a proposed solution of using a less reflective material on the towers facade is examined via glare simulations. The initial set of simulations confirmed that tower skin contributed to blinding glare particularly at 12:00 and 15:00 on the summer and winter solstice, and the spring equinox. Use of less reflective material on the tower faade concluded that the tower faade still contributed to glare and that is due to its convex geometry.
