In order to explore and address the current state of BIM (Building Information Modelling) to BPS (Building Performance Simulation) Interoperability development, its reasoning, challenges and current workflow approaches in AEC (architecture, engineering and construction industry) daily practice, the BEEP partners present the document “State of the Art analysis on BIM and numerical simulation Interoperability’’.

It seeks to provide critical insights of the current obstacles the AEC industry is facing regarding this activity, in order to allow the BEEP project partners to select and implement the most efficient semi-automatic workflow available. The document contents are as follows:

• Brief introduction and a schematic representation of the problem formulation.
• Current level of BIM and BPS integration, BIM and BPS information requirements and the importance of an effective BIM to BPS conversion.
• Interoperability and data exchange schemas.
• Existing solutions available in practice.
• Limitations of the exchange process
• Description of future research.

About the BEEP project:

BEEP project aims at strengthening the use of Building Information Modelling (BIM) to enhance energy efficiency in buildings. The testing of this emerging technology on built heritage will be performed to demonstrate its scalability to the entire building stock. The project will provide public administrations with a powerful method for the energy rehabilitation of public buildings to be supported with private funds through the Energy Performance Contracting (*). The project main outcome will be an innovative methodology based on the integration of emerging technologies tested on 9 heritage public buildings located in Italy, Spain, Cyprus, Jordan, Palestine, Lebanon, and Egypt.

(*) Energy performance contracting (EPC) is a mechanism for organising the energy efficiency financing. The EPC involves an Energy Service Company (ESCO) which provides various services, such as finances and guaranteed energy savings. The remuneration of the ESCO depends on the achievement of the guaranteed savings. The ESCO stays involved in the measurement and verification process for the energy savings in the repayment period. ESCO and energy performance contracting are mostly found in the public sector and to a lesser extent in the industrial and commercial building sectors (Hilke and Ryan, 2012). Source: European Comission
