Gaining UK planning consents, particularly in the south-east, is particularly challenging to architects. We would like to identify any extant research pertaining to the way in which sustainable or green building rating systems address--or can address--the practical realities prevalent in gaining statutory planning, or 'zoning', consents. The notion of 'practical realities' refers to the difficulties that clients continually face in making sustainable design measures beyond building regulations stack up financially and practically in terms of gaining planning consents.
