The Osborne House development aims to restore and extend an existing 1970 Modernist office building into a 157‐bedroom hotel in the West End of Edinburgh. S. Harrison Developments and Architect CDA’s designs are conserving the look and feel of the original 5-storey building with its concrete structure and façade panels. The extension, however, is designed with the addition of a modern looking glazed top level. The ground floor will be transformed into a new external restaurant terrace whilst conserving the concrete and aluminium cladding to match the quality of the original building. Two extension wings are also proposed to the south of the existing building.
RMP was instructed to conduct the noise impact assessments of the design proposals and to offer advice as necessary to facilitate compliance with the relevant standards and guidelines. Measurements of mixed road traffic noise were undertaken at representative locations at the facades of the existing building.
RMP consultants gave recommendations for glazing and ventilation for the facades to achieve typical requirements of the internal noise levels set by the City of Edinburgh Council and Hotel brand standards. RMP also considered noise from any plant units to be installed on the roof and made of glazing and acoustic louvres to satisfy the City of Edinburgh Council requirements for noise break-in at the nearest noise sensitive receivers.
RMP also conducted internal acoustic testing to inform the design review. In addition, the use of the Insul acoustic software allowed the consultants to predict the airborne sound insulation of the existing floor structure. A vibration assessment was also conducted in line with the Meininger’s Hotel brand criteria for guest bedrooms. The Project acoustic consultants provided ongoing design recommendations for the internal acoustic construction. Site inspections of the key acoustic elements of the works will be undertaken and completion testing to demonstrate that the design standards have been achieved.
