This data centre in Scotland has been transformed with a new Kalwall skylight over the central atrium. The dramatic solution was adopted by architects Atkins because the existing pyramidal roof, constructed with tinted glass curtain-walling, was ageing and leaking badly.
Refurbishment involved reuse of the existing structure to install 1,200mm wide panels of highly insulating Kalwall and to replicate the original shape. The result has been an immediate halving of the U value and a fivefold reduction in solar heat transmittance. Importantly, the whole ambience of the space has been greatly enhanced, even on cloudy days, because of the ability of the Kalwall daylighting system to distribute light evenly over the space below, while at the same time eliminating glare and shadows.
At night, the pyramid exudes an ethereal glow against a background of the Clyde and the hills beyond.
Kalwall roof systems can be bespoke (with structure by others) or are available in self-supporting barrel and low profile vaults, up to 7.4m span, self-supporting ridge roofs, up to 6m span and also pyramids. The lightness of the panels mean installation is less costly and far less cumbersome than glass. The panels have inherent rigidity and impact resistance, are largely self-cleaning and because, dirt is less obvious than on glass, frequency of maintenance is reduced.
