Doing a project!!

[Frank S]

Actually the statement of a green building must use the latest green technologies is a false hood. Many of the latest so called green technologies have a significantly higher cradle to grave foot print than many of the much older less technical or scientific ways of constructing a building. However local zoning and ordinances often are a large dictator when it comes to using some of the low tech methods in construction expanding your research to include the reuse of as many materials as possible can lower foot print indicator when the life use of the building is taken into account.
Do some research on methods of passive lighting, heating and cooling by the use of low tech and reclaimed materials for starters
