The project benefited from a range of project partners including Edinburgh World Heritage, Lister Housing Association, University of Strathclyde, Holzmanufaktur Rottweil GMBH, Simpson & Brown and Thomson and Gray. 

Cameron Kerr were commissioned to provide specialist ventilation design input. This included analysis of passive design solutions within an historic context. Cameron Kerr also provided consideration and development of innovative and novel methods of delivering fresh air with the intent of reducing energy consumption and to improve internal air quality and environment. 

The building considered is a Category B listed townhouse owned by Lister Housing Association. The specific test apartment being a three-bedroom apartment located at 22 Lauriston Place in Edinburgh.  

The University of Strathclyde led on a detailed environmental monitoring exercise which included the deployment of internal monitors to each habitable space. These monitors fed-back crucial real-time data on temperature, carbon dioxide,particulate matter and relative humidity. This data allowed for a detailed understanding of the interior dynamics which led to the development of the most appropriate ventilation solution. 

Cameron Kerr - along with Simpson & Brown - worked directly with the window manufacturer in order to direct and create the most appropriate window solution, responding holistically to air quality, energy and heritage sensitivity. 

The result of the collaboration has been the development of a novel, but practical, sash-and-case window suitable for heritage environments. The window itself tackles issues around heat loss, down-draughts, air permeability and trickle ventilation.  Solar pre-heat strategies have been considered as part of the development of the window and ventilation solution.
