A first step to consolidate and speed up the process of converting BIM into BEM

Nowadays enhancing the energy performance of buildings through deep renovation is strongly requested by the recent Directive (EU) 2018/844) and using BIMs (Building Information Model) as a data source for the automatic generation of BEMs (Building Energy Models) represents a unique opportunity to move towards the BIM-SPEED goal of 30% time-reduction and 60% energy savings.

Currently, BIM-to-BEM procedures involve time-consuming processes requiring additional input information and data corrections that should be entered manually. Besides, multiple limitations exist due to a lack of transparency of the data transferred. 

We are glad to announce that as third-party of Stress S.c.a.r.l we are part of BIM-SPEED, a project funded from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 820553 in order to develop a combination of methodologies and tools with one central information source at its core: the Building Information Model (BIM), a digital representation of a building. This model will be the catalyst for a smarter, more efficient, method of deep renovation for the residential building sector.

In the framework of this project, we have carried out an “analysis of BIM-to-BEM critical parameters and recommendations to solve the current bottlenecks”, which represents a first step to consolidate and speed up the process of converting BIM into BEM introducing a comprehensive evaluation of the actual bottlenecks and deficiencies of the existing BIM-to-BEM processes. 

The general overview of the current state-of-the-art and the more in-depth analysis of different procedures, starting from a common simplified BIM test model and proceeding step-by-step through three selected BIM-to-BEM workflows, lead towards the identification of the most relevant critical parameters and shortcomings. 
To overcome the actual barriers, our analysis investigates which strategies and key aspects can be optimized and standardized within the data exchange between BIM and BEM tools to accelerate the energy analysis and enhance the interoperability of the software avoiding the need of double modelling. 

As results of the analyses carried out, several recommendations and good practices were provided to assist the developers in the enhancement of the interoperability between BIM tools and energy simulation engines and in the improvement of the building retrofit and renovation processes w.r.t. energy efficiency, saving time, lowering costs and reducing human errors.
