The refurbishment of the British Library of Political and Economic Science for the London School of Economics features some complex glazing within the spectacular dome designed by Foster and Partners. Capping an impressive cylindrical atrium that has been driven through to the basement of the library, the glazed dome allows daylight to be drawn into the heart of the building. Andrew Purvis, project architect, explains “The form of the dome was generated from sun path diagrams. Having calculated the path of the aggresive mid-summer sun, we cut the dome off at the corresponding angle. A reflector at the front of the dome bounces the light back and down into the atrium.”
The glazing in the dome, which features Kawneer’s 1203 Curtain Wall incorporating specially designed triangular structural silicone glazed top and bottom hung vents, is also an integral part of the library’s natural ventilation strategy. Cold air drawn in through the windows on the external facade of the building moves towards the atrium and rises naturally as it warms, escaping through the vents in the dome’s glazing. Kawneer developed mock-ups of the complex 2.3m x 2.3m x 2.3m triangular opening vents, which were tested at Wintech’s testing centre in Telford, where a rig was built to mimic the slope of the dome glazing.
