Greenbank Student Village was a development scheme by the University of Liverpool. The new build accommodation has created 1,370 bedrooms for University students. The redevelopment saw six buildings replaced by three new student accommodation blocks; Derby Hall, Rathbone Hall and Gladstone Hall.
Phase One
Dyer were initially asked to supply and install chain drives as part of a natural ventilation system. This was successfully achieved by the use of CDC 200/350 chain drives, operated by 3-position natural ventilation switches. The drives operate quietly and are barely visible. Dyer also installed 12 sets of KA drives ranging from 600-1300mm stroke lengths.
Phase Two
Dyer supplied 21 EN12101-2 NSHEVs to the window contractor to fit into the curtain walling, allowing Dyer to issue certification. The aluminium bottom-hung open out windows are operated by KA 54/1000 BSY+ sets, one pair per vent. This provides a free area of 1.5m2 as regulation Approved Document B.
Certification
To allow Dyer to issue certification, the drives and window profile have been tested as a complete unit. Dyer are certified with many window profile systems, on this occasion Reynaers profiles were the preferred option.
