    That gonzo TV journalist Theroux visited one in Arizona I think. Looked a bit blingey to me, soundproofing was probably good, dunno about the insulation though. Oops just read the title again.:shamed::shocked::wink:

    Posted By: tonyWhat should the U value of the walls and roof of a new warehouse be?

    The U-value should not be a requirement itself, but rather be a consequence of meeting requirements based on energy used. So an unheated wine or beer warehouse, or indeed a museum, should be designed with more emphasis on thermal capacity and 'decrement delay' than on U-value. A cold store by contrast should have lots of insulation. How about 15 kWh/m2/year? Or should the limit be better/lower since the buildings are typically a lot bigger than dwellings?
