INdustrialised and PErsonalised Renovation for Sustainable sOcieties

Periodic Reporting for period 1 - INPERSO (INdustrialised and PErsonalised Renovation for Sustainable sOcieties)

Reporting period: 2022-07-01 to 2023-12-31

In the period we are living, efficient use of energy and reduction of carbon emissions are key factors in our fight to mitigate human impact in climate change and, as buildings account for 40% of final energy consumption and 36% of greenhouse gas emissions in Europe, the need of Zero Energy Buildings cannot be overlooked in this endeavour. Under the circular economy paradigm there is no doubt that we cannot afford the waste and raw materials impact of completely new constructions with this purpose, and, therefore, renovation of existing buildings looking for zero net energy consumption is essential. However, due to different barriers, current renovation works are not reaching the desirable number, hindering our transition into a green economy and society.
In this context, searching for a boost in the building renovation rates, INPERSO proposes innovative solutions flexible to adapt to the specific characteristics and needs of each building and user, and industrialised and digitalized processes to improve the retrofit works, reducing the time and disturbance.
To achieve this, the consortium is approaching building renovation from different perspectives: the retrofit KIT, digital processes, optimal energy use, and human-centric design.
The retrofit KIT is a set of solutions that can be combined in synergetic way: smart walls premanufactured that improve thermal and acoustic isolation and that can include heating or photovoltaics panels, windows with venetian blinds able to control light comfort and produce renewable energy; energy pods with smart control systems to minimise energy use in heating, ventilation and cooling; photovoltaic integrated panels aesthetic and adapted to different construction elements, and a façade 3D printing system to improve isolation and finishing of the building.
This kit comes together with digital tools using Building Information Models to support the renovation works, like scanning systems, augmented reality, and a cloud platform for information sharing.
With focus on the post renovation occupancy, the project will also test sensor networks and artificial intelligence to support the efficient energy use and improve the living comfort.
At last, INPERSO proposes a low carbon renovation model, involving residents, real state owners, construction companies, etc. in the design process trying to guarantee user satisfaction and sustainable behaviour.
As the project is targeting close to market solutions, all the developments and methodologies will be tested in real renovation works with very different characteristics: a multifamily building in Valencia (Spain), a heritage monastery in Velp (Netherlands), and a social shelter in Vouliagmeni (Greece).
During the initial phase of the project, significant groundwork was laid to establish a robust foundation for further development. This period was marked by several key activities aimed at defining the project's scope and objectives. One of the primary achievements was the comprehensive establishment of requirements and specifications, providing a clear roadmap for subsequent project phases. Additionally, the design phase saw the creation of prototype designs for various elements of the INPERSO Kit, highlighting essential features and functionalities. Notably, significant progress was made in the design of the façade printer, a crucial component of the project's innovative approach.
Furthermore, the project team achieved a significant milestone with the first release of the INPERSO digital platform, built on BIM principles. This platform serves as a central hub for communication among all project stakeholders, facilitating seamless collaboration and information sharing. Additionally, the Scan to BIM system was finalized during this period, enhancing the project's capabilities for data acquisition and integration. Another key accomplishment was the implementation of a Wireless Sensor Network (WSN) and the installation of energy and Indoor Environmental Quality (IEQ) sensors, laying the groundwork for a comprehensive monitoring plan. This initiative aims to study pre-, during, and post-construction conditions, providing valuable insights into the project's environmental impact and performance. Moreover, significant progress was made in defining renovation works and obtaining necessary permits, supported by simulation models that align with Low Carbon Renovation methodologies. Overall, the first period of the project set a strong precedent for future success, laying the groundwork for innovative solutions and impactful outcomes.
