Abstract
The main objective of this document is to analyse and cluster the demand-side (i.e. the building stock and the owners, investors, users) of industrialized renovation kits because of the EU building stock variability that leads to an uncertainty in the definition of the most suitable envelope solutions.
For this, in a first stage, previous experiences and initiatives at European level have been analysed to consider them as the baseline for the present work. For instance, TABULA building types are indeed the reference for most of this initiatives and projects.
Then, the key parameters of the buildings that affect the design of each of the systems have been identified (such as typologies and morphologies, regulation framework, ownership, etc.) and they have been ordered according to their importance. To do so, all the industrial partners have been involved in dedicated workshops and meetings to receive valuable feedback.
This process is aimed at defining a tool that can cover the variation in the building stock and identify limiting parameters that might make the use of some of the kits unfeasible, while helping to identify different kinds of building archetypes. This will allow to understand better which buildings typologies fit better with the industrialised approach.
The following step has been to obtain the building stock characteristics to be considered. They have been grouped according to the Delphi method conclusions. As a result, a decision tree tool has been developed in excel format. It allows, by answering several questions about the building, to know what are the INFINITE kits that can be installed. Then, different archetypes have been defined, that is, the ideal buildings whose characteristics are compatible with an INFINITE industrialised renovation.
As a final and big step, the different building parameters that are available in open data sources have been gathered, highlighting those ones of the countries within the consortium, since these ones seem the more suitable to be included in a map (linked to task 5.3). Furthermore, the ownership, tenure and age classes of residential buildings have been analysed to see where the major renovation potential is. Then, an analysis of the existing building regulations at national and European level to identify possible barriers for the industrialization approach in the renovation sector has been carried out. Finally, the current situation of the industrialization in the construction sector has been introduced, and a SWOT analysis about the industrialization has been carried out (for the countries of the project), to link them with the feasibility of installing the INFINITE kits and national conclusion have been introduced.
The activities carried out in this task have provided input for the definition of the user-centred approach and the development drivers (WP2). This work aimed also to drive the matching of the business models between demand and industry and consequently the market potential map from the demand-side perspective (WP5).
