S-HOUSE Passive house made of straw

Further to my post about Swedish passive houses, here is a very interesting project about passive houses using renewable resources.
Sustainable construction can be defined as follows: Not only the building concepts but also the components and materials which are used have to meet the present needs of the users without burdening future generations with waste disposal problems or prolonged use of an out-dated building design. Thus sustainable architecture means: form follows ethics, i.e. the design is the result of a careful consideration of functions, materials and their life-cycle performance including long term perspectives, present and future human needs and social aspects. This is the basic principle under which the S-HOUSE, a passive solar house made of renewable resources, is constructed.
