BIM in renovation projects

Building renovation is one of the current big challenges of the construction sector, which would improve the sustainability of existing structures, in terms of energy and emission savings and, as a consequence, would reduce the overall energy and CO2 emissions accounting in the building sector.


The use of BIM platforms for deep renovation projects represents an innovative solution for efficient management and use of the project information, providing a significant workflow optimization, and ensuring interoperability with other tools in order to make the decision making processes more efficient.


The development of a BIM platform including methodologies and tools to be used in deep renovation projects is the main goal of the Horizon2020 research project “BIMSPEED”

The BIMSPEED database

Within the EU-Funded Research Project BIMSPEED (H2020-GA 820553), a BIM Object Database has been developed as a support for the renovation design. The database lists the components mostly used in renovation projects, enclosing a set of general and specific properties, which can be used in a BIM environment for running energy performance and sustainability assessments.


The BIMSPEED database is composed of a number of materials and components used for deep renovation of buildings. Building renovation components are defined as the building elements that can provide a contribution to the reduction of the overall energy consumption and/or to an enhanced environmental and economic sustainability.


The database collects a set of parameters and a set of files. The parameters can be divided into four packages: the “Info package”, the “Energy package”, the “LCA package” and the “LCC package”. In particular, the info package includes the general information, such as the component category, the typology, the application area, and others. The latter three packages include more specific information, being the data needed as support for Energy Performance Assessment, Life-Cycle Assessment (LCA) and Life- Cycle Costing (LCC). Data collected for the Energy Performance Assessment vary considering different components categories
