Environment minister Michael Meacher pulled no punches addressing architects and property types at the 'Greening of Commercial Property' conference last week. Tell me what you want included in the legislation coming your way, or you'll get what I'm going to dish out, was his blunt message. Perhaps the latter is the only way anything will get done, if the remarks of Davis Langdon & Everest's Paul Morrell were anything to go by. Only legal requirement or market demand would bring a change of attitude, he claimed. A bit harsh given developments that have already taken place in the work of people like speaker Rab Bennetts. It was left to the aj's very own Paul Finch to note that high densities and over-engineered buildings, two of the hallmarks of commercial property output (where allowed) now looked impeccably suitable for long-life, loose-fit, low-energy buildings. Can it really be 25 years since the riba launched that campaign? Alas, yes.
