Following several years of research and development around the subject of BIM, its impact on the design and handover of buildings is now becoming visible across the construction industry. Changes in design procedures and information management methods indicate the potential for greater utilisation of a Common Data Environment in areas other than design. To identify how these changes are influencing the engineering design process, and adapt this process to the needs and requirements of building performance management requires consideration of multiple factors, relating mainly to the stakeholders and processes employed in these procedures. This thesis is the culmination of a four year Engineering Doctorate exploring how BIM could be used to support non-domestic building energy performance management. It begins with an introduction to the research aim and objectives, then presents a thorough review of the subject area and the methodologies employed for the research. Research is split between eight sequential tasks using literature review, interviews, data analysis and case-study application from which findings, conclusions and key recommendations are made. Findings demonstrate disparity between different information environments and provide insight into the necessary steps to enable connection between BIM and monitored building energy performance information. They highlight the following factors essential to providing an information environment suitable for BIM applied performance management: Skills in handling information and the interface between various environments; Technology capable of producing structured and accurate information, supporting efficient access for interconnection with other environments; and Processes that define the standards to which information is classified, stored and modified, with responsibility for its creation and modification made clear throughout the building life-cycle. A prototype method for the linking of BIM and monitored building energy performance data is demonstrated for a case-study building, encountering many of the technical barriers preventing replication on other projects. Methodological challenges are identified using review of existing building design and operation procedures. In conclusion the research found that BIM is still in its infancy, and while efforts are being made to apply it in novel ways to support efficient operation, several challenges remain. Opportunities for building energy performance improvement may be visualised using the modelling environment BIM provides, and the ability to interface with descriptive performance data suggests the future potential for BIM utilisation post-handover.
