CON!S: ! ! !
Lengthy and no conclusion/ summary Too many excerpts and tables “the author has found over the years that many outspoken critics of codes calling loudly for looser standards and ‘creative freedom’ are architects with limited talent, to whom the rhetoric of ‘freedom’ and ‘flexibility’ is merely a mechanism to conceal bad, or at best mediocre, design under a smokescreen of ‘creativity’ - Opinionated author; meant to be theory? Heavily focused on USA; what about other countries! positive lessons?
To date only energy has been incorporated If the BCA extended its scope it could result in a holistic concept of sustainable development and implement integrated sustainability through a single regulatory tool. (Wilkinson & Dong, 2007)
