(Table D in S1 File).

Format of cross-table of housing systems, HSs, and given welfare scores, GWS, as column headings in green, taken from Table A in S1 File, and main welfare parameters, row headings in yellow with their weighting factors, WF, taken from Table F in S1 File. The task here was for the respondent to assign parameter level scores, PLS, on a scale from 0–10 (light blue field) for every parameter-HS combination. Inserted GWS and WF values represent average expert scores, showing only parameters that had n> = 2 PLS values for all HSs shown (see Table K (Summary table) in S2 File ‘Data exploration’).
