Towards the Energy Transition of the Building Stock with BIPV: Innovations, Gaps and Potential Steps for a Widespread Use of Multifunctional PV Components in the Building Envelope
Round 1
Reviewer 1 Report
The paper presents a discussion about on the uso if BiPV in the building stock, focusing on platforms with materials as well as on innovations, gaps and potential steps for a widespread use of multifunctional PV components in the building envelope. On figure 1 specify the date when you counted the date as some platforms grow fastly with case studies and products. Section 2 must be inserted after section 3 as it is the d’Orta step of the methodology. Anyway, here in discussion on the state of the art of project was done. This part could be interesting for finding other platforms. In section 4 you defined mainly aesthetic parameters. Why you select this approach? Especially energy parameters are not defined. The sentences from row 254 to 264 are not justified with references. The research realized in IEA Task 59 on Risk-Benefit Assessment Scheme for Renewable Solar Solutions in Traditional and Historic Buildings can help you to support you on these theories. Figure from 6 to 8 must be translated in English as now are comprensibile only for Italy. Otherwise, cut them. It is not clear the use of this catalogue. Is it a digital catalogue or not? Is it a book? In which way people can use it? In which way it can improve the international knowledge on BiPV system? Is it free accessible? Conclusion are really interesting and deep analysed, but the link between than and the catalogue is not defined. Thus, they seems more general conclusions based on the experience of the authors than specific conclusion related to the analysis of the catalogue.

Many thanks for your comments
Reviewer 3 Report
Paper reviews building integrated photovoltaics technologies from a practical point of view for the Italian and European scenario- The paper is very relevant under current NZEB scenario and is well aligned to the journal scope. Some minor comments are given before paper publication.
- Avoid using abbreviations in the abstract; all abbreviations should be defined first time used
- Where is the paper novelty? It should be stated clearly at the introduction
- Rapid growth of solar energy research and future trends, specially for PV, should be mentioned in the introduction; relevant reference Quo vadis Solar Energy Research?, Applied Sciences should be consulted.
- Information described in section 2 and that is represented in Figure 1 should be summarised in a table instead (including link and/or reference) so readers could get the most relevant information at a glance.
