Abstract: With unsustainable greenhouse gas emission and irrational energy consumption, building sector have big impact on environment pollution and climate change. In order to reduce the building sector impact, the majority of current buildings need to be renovated and new buildings built as Nearly Zero-Energy Buildings (NZEB). Since for building renovation and new NZEB, together with integrated design, management of relevant information is crucial, the use of Building Information Modelling (BIM) becomes evident. BIM is a concept which promotes integrated design process in a way that connects all key stakeholders by collaborating on the same information model. In order to assess energy demands of renovated building and therefore perform an optimization process, BIM must be transformed in Building Energy Model (BEM). Today, BIM-to-BEM Information Process (BBIP) is still not fully developed which results with some information being lost during BBIP. Those lost information must be re-entered to create correct BEM. This paper proposes a procedure for tackling this BBIP information loss. This procedure is summarized in the workflow steps needed to acquire correct information about the building as an input for optimization of envelope design in deep energy renovations and exploitation of the building during its lifecycle by using BIM tools and processes. Moreover, to increase the use of BIM for energy efficiency purposes, competences of all building stakeholders must be enhanced.
