Abstract
Reducing carbon emissions and addressing environmental policies in the construction domain has been intensively explored with solutions ranging from energy efficiency techniques with building informatics to user behavior modelling and monitoring. Such strategies have managed to improve current practices in managing buildings, however decarbonizing the built environment and reducing the energy performance gap remains a complex undertaking that requires more comprehensive and sustainable solutions. In this context, building information modelling (BIM), can help the sustainability agenda as the digitalization of product and process information provides a unique opportunity to optimize energy-efficiency-related decisions across the entire lifecycle and supply chain. BIM is foreseen as a means to waste and emissions reduction, performance gap minimization, in-use energy enhancements, and total lifecycle assessment. It also targets the whole supply chain related to design, construction, as well as management and use of facilities, at the different qualifications levels (including blue-collar workers). In this paper, we present how building information modelling can be utilized to address energy efficiency in buildings in the operation phase, greatly contributing to achieving carbon emissions targets. In this paper, we provide two main contributions: (i) we present a BIM-oriented methodology for supporting building energy optimization, based on which we identify few training directions with regards to BIM, and (ii) we provide an application use case as identified in the European research project “Sporte2” to demonstrate the advantages of BIM in energy efficiency with respect to several energy metrics.

Summary
Global warming has drastically increased the pressure to reduce energy use in buildings. The process involves the traditional disciplines, and many new professions in areas such as energy of designing, re-purposing, constructing and operating a building or facility involves the and the environment [5]. Such advanced support from digital tools is likely to allow for significant improvements in the quality energy performance of buildings, as well as time and cost-savings to preserve competiveness of and energy performance of buildings, as well as time and cost-savings to preserve competiveness of European businesses During these different phases (as presented in Figure 1), the building. We use an application use case related to energy efficiency in buildings realized as part of the EU FP7 Sporte project based on which we demonstrate how BIM can reduce energy consumption and improve the overall building management process.
