Unfortunately Architecture is obsessed with green issues now. A practice may as well declare itself bankrupt if its website and marketing material doesn't shout from the (sedum planted) rooftops about how "sustainable" everything is.
Building Regs is now fully focussed on energy saving, however while paying less money for fuel itself is no bad thing, the whole thing is wrapped up in the unproven theory of man-made global warming. No one dare speak out against MMGW for fear of being branded some sort of new-age heretic.
I noticed a few years ago, a certain global steel and aluminium cladding company's website had changed to feature large pictures of rainforests instead of pictures of new factories, and they were now touting themselves as the saviours of the environment. This is a company that makes panels of chemically formed and bonded insulation clad in chemically coated steel, or aluminium. Hardly haybales and horsehair wattle and daub now is it?
Even concrete producers are now saying how "green" concrete is, compared to steel.
When Middlesbrough College was built (nearby) they had a "sustainability consultant" on site the whole time who measured the carbon footprint of everything that happened on site. Didn't reduce it, just measured it, for thousanRAB of pounRAB of fees.
Its political correctness.....gone mad (Stewart Lee)
(Though I'm blaming OH for not setting it up properly!)
