Glassolutions played a key role the creation of The Bennet Building having been appointed to deliver a technically demanding glazed façade with an intelligent solar control function – all designed to optimise energy efficiency and occupier comfort in a high quality working environment. Their glazing contract also included an 80m2 glass spiral staircase, which forms an emergency escape route within the flagship building.
With the client’s vision to create an impactful building which acts as a 'signpost’ to the central campus, the primary consideration in Norr Architects’ design was how the building looks from a 360 degree view. Achieving this, the design assumes a radial form springing from a central drum which continues up through the building and above the roof to act as a landmark feature when viewed from the campus entrance. The glazed façade sweeps around following the radial form.
Close collaboration between the architect, façade systems manufacturer and Glassolutions arrived at the Schueco FW60+ SG glazing system which was applied in a most innovative way. The bespoke solution developed by Glassolutions combined curtain walling with computer controlled blinds incorporated into the cavity of the double glazed units. Utilising its Saint-Gobain group links, Glassolutions worked with sister companies Saint-Gobain Glass and interstitial blind systems manufacturer Eckelt to deliver a technically excellent robust solution.
The extensive glazed façade controls solar gain with variable levels of solar control through the use of 10mm SGG COOL-LITE ST150 glass for the outer pane, and an 8mm Planitherm One HST inner pane in the 47mm sealed units. The 29mm cavity features Ecklite SC06 interstitial blinds which provide additional shading, which are computer controlled by the occupants and capable of being overridden in local areas. Weather stations on the roof dictate the opening and closing of blinds which produces a spectrum of g-values. The COOL-LITE ST150 solar control glass maintains a g-value of just 0.3 when the blinds are open, but this is reduced to virtually zero when the blinds are fully closed.
