Norwich Union invests in chilled beams in HQ refurbishment

The £90 million phased refurbishment of the headquarters of Norwich Union in Norwich saw the installation of a wide range of chilled beams from Trox UK. The total value to Trox over all four phases of the project was £3.5 million. The project embraces seven Norwich Union buildings covering 3700 m2, including the Grade 1 listed Surrey House built in the early 1900s. The active multi-service chilled beams include loudspeakers, PIR detectors and lights that use the DALI control protocol to deliver flexibility and save energy. All the elements in the beams, each of which were fitted by Trox at its Thetford factory, had to be programmed for the area in which they would be installed. The efficiency of this project is improved by using inverter-driven pumps to deliver chilled water to the beams according to demand. A comprehensive analysis of the performance of the beams was carried out using Trox’s test facilities at Thetford. Tests included thermal, air distribution and light distribution. Bovis Lend Lease chose Trox for this project having worked with the company on previous projects. Trox had also worked with developer Land Securities. Building-services engineer is FaberMaunsell, and the architect is Aukett Fitzroy Robinson. The project is due for completion by the end of 2007.
