We need a set of 4 renders for different finishing of a small building (i.e. less than 100 m2).
One should be a wooden finishing, with PV and solar thermal on part of the roof
One should be a covering with a specific type of black tiles, again with renewables on part of the roof
One with a specific brick and a specific roof tile and again renewables on the roof
And one most probably with a different type of grey tiles and renewables on the roof
Renders should be of high quality as they have to be used to convince the local administrators
