ABSTRACT
The emphasis of both building and energy modelling has often been on new-build with existing buildings having minimal attention due to incomplete information or the lack of any immediate prospect of validation. This paper is about discussing a new approach of energy modelling for existing facilities using UK Rotherham Hospital (TRF, 2013)[1] as an existing facility with no BIM models and few available records to be explored during the EU STREAMER, 2013 [2] project.
This paper will examine in detail the methods used to capture sufficient information relating to the existing building stock, from written text, poorly reproduced drawings and on-site monitoring. The paper will also explain the tools used to capture that information including textual analysis and mark-up, mapping of semi-structured information to IFC, non-interactive simulation and the deployment of gaming strategies to identify optimum strategies. Multiple strategies were tested against two departments of similar size and construction but with differing operational needs.
