High Performance Accoustic Design, Colman House, University of East Anglia

Introduction

Colman House is a student accommodation block at the University of East Anglia. It opened in September 2004 as a part of the expansion of the Norwich campus. With buildings of this nature, the aim is to provide an optimum level of accommodation without compromising residents’ quality of life, or the function of the building. Insulation against noise is an important factor.

 

 



 

Description

 

University halls, hotels and hostels all have to comply with the Building Regulations acoustic Part E requirements of 2003, and are not eligible to use the Robust Detail Scheme (see Solutions section), instead requiring pre-completion testing (PCT) to be undertaken.

The building was constructed using the tunnel form construction method, creating a monolithic structure. This system is replicable, therefore may be used in future projects.

Acoustic testing took place in August 2004, assessing two carpeted 250mm concrete separating floors, without ceiling finishes, and two 180mm concrete separating walls. Both floors exceeded the regulations and also met the levels which would be required by Robust Details. Further potential acoustic control could have been achieved had a floating floor and suspended ceiling been in place. The walls had 2mm plaster skim finishes but no other wall linings, and also met the PCT requirements. Performance could also have been stronger had further wall linings been in place.
