article_snippet: Theoretical skyscrapers   have been blamed for casting a shadow over urban areas and occasionally creating a 'death ray-style' beam of sunlight capable of melting cars on the street.
article_snippet: So architects have now designed skyscrapers which don't block out the light by diffusing the light onto a wide area in a bid to tackle the problem of shade encroaching on public space in London.
article_snippet: The revolutionary 'No Shadow' design is the brainchild of architects NBBJ, who used a computer program to design two buildings, which work together to disperse and refract sunlight.
article_snippet: They are designed so that when one building creates shade, the other can act as a huge curved mirror, allowing the light to be reflected downwards into the light shadow.

article_snippet: Christian Coop, NBBJ's design director, said: 'The relationship between the sun and shadow is the relationship between similar buildings.
article_snippet: Christian Coop, NBBJ's design director said the project is about 'improving the quality of our urban environment... finding a way in which we can have the tall buildings we need without losing natural light on the areas below'.
article_snippet: Mr Coop hopes that architects will use this type of modelling to see how architects designs will affect the light levels around architects buildings.

article_snippet: Mr Coop said The theoretical development could also be adapted to control how much sunlight is reflected at different times of year.
article_snippet: Peter Murray, head of the New London Architecture (NLA) forum, said the 'No Shadow' design was a 'perfectly feasible' theory.
article_snippet: No Shadow' added  that one of the problems people have with skyscrapers is the long shadows people cast: 'If you can reduce that, that must be a good thing.'

article_snippet: Dr Philip Oldfield, an expert in tall buildings at the University of Nottingham's Department of Architecture, said: 'What's great about the project is the focus on tall-building form and shape, not only to look dramatic, but to contribute to creating a comfortable space at ground level.'
article_snippet: Sydney's One Central Park has moveable mirrors that reflect light onto shaded areas below or block the sun during the hot summer.
