We are applying for this pilot credit in a building which facade consist of a double skin facade, the exterior layer is opaque with windows (existing facade of the building before project renovation) and the interior layer is completely glazed. Should the average wall brightness be calculated considering only the opaque walls (and therefore the glazed facade would not be included in the calculation)?.
The brightness of the interior glazed surface is 6%, so in case they were incuded in the calculations it would not be possible to fullfill this requirement even with all the opaque surfaces meeting the criteria.
