Use of performance analysis tools, like DIVA and SEFAIRA, in early stages of architectural projects design

My name is Michelle Sido Hawli, I am a student of the MArch. In Digital Architecture and Tectonics from the University of Nottingham. I am currently developing a research on the impact on building performance that the use of environmental analysis tools, like DIVA and Sefaira in the early stages of the design. I will compare this research to post optimization approaches, in which the analysis is made in later stages. 

I would be grateful if you could answer a short online questionnaire here: https://www.surveymonkey.co.uk/r/QTCKRFS
