Though we know reflection of sun rays can cause fire, this news item made me to keep in mind that I should consider this aspect also while studying the safety aspects of building design for issue of safety clearance. The news item states that the sun light reflected from the concave shaped building surface caused partial melting of a car parked below.
This implies that the distance of impact needs to be assessed and the designers of the buildings have to ensure that no flammable/combustible materials are kept in this range unless suitable measures are taken.
