BIM-based holistic tools for Energy-driven Renovation of existing Residences

Project description

New tools for energy-efficient renovations

Energy efficiency is a key requirement of green and sustainable buildings. But the building sector is responsible for high CO2 emissions. The EU construction and renovation sector has a lot to do in order to reach energy efficiency and optimised methods. In this context, the EU-funded BIMERR project will design and develop an ICT-enabled Renovation 4.0 framework. Specifically, this will include enhanced digital models of existing buildings that go beyond geometrical information. BIMERR’s main deliverable will be a toolkit to support renovation stakeholders throughout the renovation process of existing buildings. The toolkit will be validated and demonstrated in four buildings in three EU Member States. Two residential buildings (one in Poland and the other in Spain) will be used for pre-validation.


Building Information Modelling is a critical element in the digitalization of the construction industry, which is necessary in order to unleash huge efficiency and productivity improvements. BIMERR will design and develop a Renovation 4.0 toolkit which will comprise tools to support renovation stakeholders throughout the renovation process of existing buildings, from project conception to delivery. It comprises tools for the automated creation of enhanced building information models, a renovation decision support system to aid the designer in exploring available renovation options through an the accurate estimation of renovation impact on building performance as well as a process management tool that will optimize the design and on-site construction process toward optimal coordination and minimization of renovation time and cost. At the heart of the BIMERR toolkit lies an interoperability framework, which will enforce semantic interoperability among BIMERR tools as well as with third-party legacy ICT tools to enable seamless BIM creation and information exchange among AEC stakeholders in an effort to enhance the rapid adoption of BIM in renovation of the existing EU building stock. The BIMERR toolkit will be validated and demonstrated in 4 buildings in 3 European Member States. Two buildings will be used for pre-validation and implementation refinement and the refined BIMERR toolkit will support the actual renovation design and works in one residential building in Poland and a second one in Spain. The assessment and evaluation of the BIMERR toolkit after these real-life activities will feed material into two supporting horizontal project activities: i) dissemination and exploitation of project outcomes through the creation of best practice examples of BIMERR use that will guide further replication effort, and ii) promotion of BIMERR outcome to the most relevant standardization bodies.
