ASM-Market Research and Analysis Centre started working on developing market insights within a Business Plan that will be elaborated throughout the entire life of the BERTIM project. This document will be delivered in four editions (now and in month 12, 37 and 48 of the project duration). It is intended to support the decision making in the definition of the BERTIM prefabricated modules. Ultimately it will help to elaborate business models used for the exploitation of the project outcomes, especially the main exploitable results: the BERTIM holistic renovation process approach, RenoBIM Software Tool, and the Prefabricated self-supporting timber modules with the integration of the HVAC system.
The group of tasks dedicated to the Intelligent Modelling Based methodology for the holistic building renovation process with prefabricated modules focuses on the definition of the requirements, the specifications and the methodology to develop the prefabricated modules and the decision supporting tool. The work is divided into five tasks.
The first task goes through the building stock in Sweden, Germany, France and Spain. It describes living area, building typologies, energy performance, ownership variations, as well as structures. From this information, the suitable buildings for prefabricated wood based refurbishment modules have been selected. In Sweden, it is decided that buildings built between 1955 and 1970 are suitable due to their low insulation levels (if energy retrofitting has not been done previously) and lack of air recovery systems. For Germany, more recent buildings are identified such as those built between 1970 and 2000, especially large housing estates, which constitute about 20 % of the building stock. For Spain, the multi-family blocks built between 1940 and 1980 are considered particularly interesting.
RenoBIM software will be the application for the first stages of any BERTIM project. It will be a cloud-based platform, to give help to design first and then decide in the best way, before any engagement of manufacturing process. As its name indicates, the inputs and outputs of RenoBIM will be based on IFC (Industry Foundation Classes).
RenoBIM will first allow importing a 3D model concerning the extern walls and roof top of the building. The acquisition of this 3D model will be based on classic technologies with theodolites or cloud of points with 3D scan. A guide will be produced to obtain the best results with different existing tools to create this 3D model and then import it into RenoBIM with IFC format.
