There is no one-size-fits-all renovation process

BIM4REN is developing a set of easy-to-use tools & services in the same common Open Environment for an agile, adaptable and fast renovation process that can be used in real, everyday projects.
Today’s construction professionals, and in particular SMEs need suitable tools & flexible methods to facilitate their work & improve their production times, while ensuring environmental targets. By considering the skills and capacities of the users and the different phases of the renovation process, BIM4Ren can adapt to different projects, business models and professional needs.

What will our tools help with?


One of the main stakes of any renovation is to characterise the initial state of the building. Some tools will allow end-users to gather such details as geometry, state of degradation, energy consumption, thermal comfort or stakeholder requirements in a quick and efficient process that can provide an adapted description of the building and information for further decision-making.


Once data is collected, construction professionals need to easily sort, classify, synchronise and secure such large amounts of information. By using extended BIM capacities, like enhanced IFC and Linked Data, BIM4REN will allow the integration and handling of this information into one single environment so that the construction value chain can work collaboratively and with increased efficiency.


Another set of BIM4Ren tools will facilitate the design process by accessing assessments models such as energy consumption evaluation, cost analysis and decision support tools that help in the selection and validation of different renovation scenarios. Our tools will include both high-end and quick’n’easy solutions to cover a whole range of needs.

A tool for every step of your renovation project.
All in a One Stop Access Platform.

BIM4Ren is a fully web-oriented, decentralised platform.
Through a single entry point, the BIM4Ren One Stop Access Platform (OSAP), users will have access to innovative tools to guide them in the creation of a renovation project. We have grouped our tools in 5 different categories applicable to diverse renovation workflows scenarios.

In line with the European Union’s Open Innovation 2 Paradigm, workflows are backboned by a novel, state of the art, open and decentralized environment. Our BIM-based tools are integrated into it and are easily accessible from a single entry point, granting access to all end users to the most adequate solutions to its renovation needs and goals.
