[ ] ‘CURRENT_ENERGY_RATING’ can be added/visualised in the ‘Energy Performance’ data category, under ‘Energy Rating’, to populate the ‘Residential Building Energy Rating’ data
-
[ ] ‘BUILT_FORM’ can populate data in Typology, for the Attachment/Adjacency layer . But for this data, we need to add two more data entries/colours on the map (‘Enclosed End-Terrace’ and ‘Enclosed Mid-Terrace’) in addition to the existing ones (‘Detached’, ‘Semi-Detached’, ‘End-Terrace’, ‘Mid-Terrace’).

[ ] EPC building age data to 'Architectural Style 'section ( ask Loughborough to prepare) but only able to be done for certain age bands-(EPC age bands are: Pre1900; 1900-1929; 1930-1949; 1950-1966; 1967-1975; 1976-1982; 1983-1990; 1991-1995; 1996-2002; 2003-2006; 2007-2011; 2012 onwards). The ones that can be absorbed into the 'architectural style' section are as follows:
For 'Victorian'- Add 'Before 1900' band - (limited no. of Georgian buildings included in this can be extracted later using Listed building data) For '1946-79 (Post war)' add 1950-1966 and 1967-1975 bands For '1980-1999 (Late 20thc)' add 1983-1990 and 1991-1995 bands For '2000-2025 (Early 21stc)' add 2003-2006; 2007-2011 & '2012 onwards' bands Others bands cannot be integrated as these cross over style dates but quite a lot of data will be able to be visualised using the above

As asked by @polly64
https://www.owenboswarva.com/blog/post-hou2.htm records Owen Boswarva's detailed efforts to gain clarification on permitted reuse of EPC data, from Dept for levelling up, housing and communities (DLUHC), and on the classification of EPC data as personal data subject to GDPR.
Though the outcome was that DLUHC revised view of EPC data as 'personal', in Colouring Cities it is considered an area where sensitivity is required as how much energy each household uses can be used to infer lifestyle, income, activities within tpersonal space. Because of this, though DLUHC EPC ratings will be recorded for each property in Colouring Britain (as they are published by government) they are not currently being visualised by building but aggregated at block level.
Aggregation is also necessary as a buildings may contain mutliple flats each with different EPCs ratings. It is important note that EPC assessments are not carried out by trained surveyors.
