In 2016 Imperial College London acquired the neighbouring disused Royal Mail Post Sorting Office from the Science Museum, sitting on the corner of Exhibition Road and Imperial College Road.
Architects Pascall+Watson were employed to devise a sensitive yet practical design for the change of use of this four storey building. As part of the plans, thought had to be given as to how to minimise carbon consumption, as well as reduce energy use and wastage in line with the College’s Environmental Policy.
A significant amount of heat and energy can be lost through poor performing windows and due to the planning restrictions on the new Dyson Building, the numerous beautiful original single glazed windows of all shapes and sizes had to be retained. Therefore, Pascall+Watson specified secondary glazing to improve their performance.
Over seven different types were installed to match the varying styles; large sweeping curved headed casements were treated with matching sightline Series 41 side hung casements, tall traditional box sash windows were treated with Series 20 and 25 vertical sliding units, along with a tricky installation of high-level stairwell port hole windows at the top of the building. To increase energy performance further, the units were glazed with 6.8 low-E laminate glass.
On the façade overlooking the service area of the Science Museum, obscurity glass was specified, to prevent distractions for the researchers and staff. The windows overlooking the busy thoroughfares of Exhibition Road and Imperial College Road were fitted with a cavity to provide added noise insulation, creating quiet conducive spaces for learning and meetings. It was decided to enhance the security of the ground floor windows with Secured By Design accredited units, the Police Preferred Specification.
