Previously occupied by Southwark Council, this £6.6m project involved the major refurbishment and conversion of four 18th century buildings, three of which are Grade II Listed, to provide campus-style halls of residence and other facilities for students attending Camberwell College of Arts. The development aimed to achieve a BREEAM "very good" rating and provide a quiet and secure environment for the students. The 350 existing single glazed sash windows could not meet the necessary performance levels but an effective solution to both the insulation and security requirements was found with Selectaglaze's systems. The designs were sympathetic to the existing windows using matching sliding sash units or full sized hinged casements. Toughened low emissivity glass was specified to maximise thermal insulation, achieving U-values below 2.0, and improving safety. Vulnerable windows were treated with products having a Police Preferred Specification under the Secured by Design initiative and all windows were positioned to optimise sound insulation.
