I have a building which wraps a round a courtyard on 3 sides and on the fourth is an existing building - this building will be maintained, this is almost all the non roof area for the project. Would it be acceptable for this credit if it can be shown that the mean shade coverage (based on summer solstice) would shade at least 50% of the courtyard as its very small? or can this credit only be achieved through material type, architectural devices or vegetation?

Vivien,
You should be able to document the credit showing that at least 50% of the courtyard is shaded on the summer solstice. The credit does require that the structures shading the hardscape surfaces have an SRI value of at least 29, which means that you will have to ascertain the SRI value of the new and existing buildings.
