Abstract [eng] Energy audits are an integral part of the overall energy savings strategy in the building sector. The signif- icance of energy audits was confirmed both by their adoption by the European Energy Savings Directive (2012/27) as well as by the development and issuance of a large number of European standards (standard series EN16247, EN 15378, EN 16798, EN 16946, EN 16947 etc.), related to the energy audit of buildings and building systems. However, current practices for conducting energy audits in buildings do not adopt the latest developments in the field of Industry 4.0 practices, resulting in the general belief within the engineering community of building physics that energy auditing can be further updated and improved. This work aims to introduce a novel approach for the improvement of existing building energy audit practices with the adaptation of building information models and associated data. The study presents the potential of evaluation process utilizing building information models for constituent energy audit procedure – assessment of building energy consumption related to building envelope. The question of whether there is room for further adoption of digitization practices in carrying out energy audits, as well as the possibilities of developing new tools in this area are addressed. Following this, the main outcome of this study is the overview and analysis of Industry Foundation Classes schema building information model data structure and its interrelationships with the aim of using the extracted information to digitize energy audit procedures. Research approach covers digitization of building energy consumption assess- ment influenced by building envelope characteristics, as well as evaluation of economic and energy aspects for possible building shell optimization scenarios. The study also presents the results of a case study evaluation carried out with the developed tool using building envelope modification feature for various environment and economic parameters. Additionally, the architecture, and the rationale for the developed tool backed, used to extract necessary information for implementing building energy audits are presented. We finalize with the discussion on upcoming developments in the field and on future work of this study.
