QUESTION:

Where can I get material information so that I can make a reasonable attempt at assessing the life cycle costs of a building ?

ANSWER:

Unfortunately that information is location specific and currently quite difficult to get, which is why the default material library contains zeros in those fields. If you have access to such information, then ECOTECT provides the facilities for you to properly use it. If not, then you can simply ignore those features as you could never have made them a design consideration anyway.
