During a sunny day in September 2013, Martin Lindsay's Jaguar XJ was partially melted by a building. According to Popular Science magazine, the sunlight was concentrated and reflected from the nearby "Walkie Talkie" building that was being constructed nearby. The 37-story mirrored glass structure had a strong curve that focused the sun's light on this one "hot spot."
While this structure wasn't completed or inhabited by tenants yet, this story should be a warning sign to building and property managers. The building ended up paying the repair costs for fixing the melted components of the Jaguar. Sunlight can seriously impact the interior of your building, the exterior and the area around the structure. Make sure you know what to expect this summer when the sun shines all day.
The Walkie Talkie's unique concave design made it the perfect shape to concentrate the sunlight at the car's parking spot. This extreme and directed heat only occurs for about two to three weeks a year, according to Popular Science. The rest of the time the sun is in a different position and therefore doesn't create the same concentrated heat. However, similar incidents have happened with other buildings in the U.S. and around the world as well.
Whether you're working with a 9-story structure in a suburban office park or a high-rise in the city, if your exterior is mainly glass you do have to worry about reflecting heat and sunlight. Popular Science explained that mirrored glass structures can reflect nearly 100 percent of the light back. So make sure you know if this is putting any properties in danger throughout the year so that you aren't surprised by a hefty repair bill for a car's tires.
There are few regulations about how a building should manage the light and heat it's reflecting. So vigilance and working with the local municipality may the best option. The parking spot where the Walkie Talkie building melted the car and the two next to it are now off limits.
While keeping an eye on your building's sun reflection can help insulate your building's owner from litigation, there are also other concerns that you should take into account when it comes to your building and sunlight.
