== Your edits to passive house == 

 The text i deleted was this: 

 "Furthermore they achieve one key green-building goal of reducing energy use and greenhouse gas emissions for the life of the building not all types of passive houses can be considered "green" in other areas because of the heavy use of artificial materials, insulators and finishes (which slowly decompose naturally)," 

 Comparatively passive houses don't use significantly more materials and there is no specific need to use 'artificial' materials as a passive house can be made fully from timber/wood fibre or other natural materials. The embodied energy in a building is small in comparison to it's total lifetime energy consumption. These are not specific criticisms of the passive house approach. 

  
  "...high energy consumption and environmental impact for producing building blocks off-site and transporting them on-site for prefabricated houses."  

 Producing blocks off site isn't a SPECIFIC criticism of a passive house. All buildings (even earthships) need some kind of building material transported to site, once again an unspecific criticism, a criticism of building in general. 

  
 "Additionally, setting up a passive house (still) requires revamping of the natural environment of the building site and ground for house foundation (especially for underground heat exchanger)." 

 An underground heat exchanger is not a necessity of a passive house. Once again almost EVERY building needs some kind of ground work to occur, this is a criticism of building in general and not PH specifically. It just all seems too vague; having been to several PassiveHouse conferences I have never heard this criticism, because it wouldn't be taken seriously. http://www.passiv.de/
