【正文】 he first rule of thumb is the rule for cooperation, collaboration, teamwork. A mondial and disciplines crossing synthesis and a symbiosis of even opposing ideas, approaches strategies and 8 expectations are needed in order to survive as humankind at least with a minimum of health. The Method Holistic Participation – MHP is such an instrument, which can help to bring the factors of a plex problem together in order to find or create an optimal solution. By means of the rotating and ‘weaving structure’ in the sequence of exploration, developing, design but also consultation and decision phases it is possible that the opposing participants of experts, users and clients can e to a mon solution which will respect the minority and which will be better for the whole than any possibly partially good looking solution. We could pare our (humankinds) situation with the situation of Crew of a boat or a space ship in danger. Everybody has to cooperate positively in order to make the chance for success high as possible. The second rule of thumb is a rule for a proper choice of a building material. A matrix helps to orientate on the possible choices: On the left side we distinguish the various origins of a material: growing plants – growing animal – minerals (metals included) – mixtures. On the right side we see the gradations of the impact on the raw material in order to make it suitable for the application: without treatment – (s)lightly treated – heavy treated – transformed. In both groups of categories we can see the lower we look the more risks we will face because of the facts that the material is not renewable or difficult to reuse and the fact ….. more energy and transport will be needed. The risks for health hazards as well as damages of the environment are the bigger the lower in the diagram a choice will be made for a building material. INNOVATIONS In the last years, more and more customers asked for healthy and/or environmentally sound dwellings and working places. They seem to be still in the minority. Even much less experts strive towards buildings with the described qualities in spite of so many attempts by some NGOs and a growing number of governments. Looking to conferences and various publications one could get the impression, that some progress is made: lots of conferences are dedicated to sustainability and Building and Construction, often 9 also in relation to Health. Ten years ago it was only the name, which carried Sustainability. Nowadays we get already contributions, which contents have a serious relation to sustainability. Still we see an enormous gap between the possibilities, the taken opportunities and especially the willingness towards sustainable building. The models and realised model projects, currently propagated by various professional and governmental institutions reflect a kind of more or less usual sustainable building: Replacing of highly poisoned materials or materials with a lot of embedded energy, be less poisoned or clean materials or materials which less embedded energy。 some energy saving during the exploitation by the implementation of passive and active solar technologies, whereby the question remains whether active solar power with all necessary equipment is really more environment friendly than the traditional solutions。 and some more similar precautions are of course already highly wele! Excursions to objects, which fulfils these criteria, exhibitions of those projects and buildings and some petitions, held in order to gain ideas and plans for sustainable buildings and settlements brought the whole development clearly further. Surprisingly enough the results of the petitions went hardly beyond the relatively easy reachable possibilities. And the usual way of sustainable building is still far away from a substantial contribution towards significant minimised use of resources and energies. After a period (starting 1965) of designing and realising a few (early historical examples of) healthy and environmental conscious buildings specifically under the term Integral BioLogical Architecture (IBA) the author started also to develop building principles and systems GaiaBuildingSystems (GBS) which answer the demands of higher than usual sustainability for building Redundant to mention that sustainability do not go (automatically) hand in hand with durability. The Straw Panel System There are at least two approaches, which basically could help the Poor as well as the Rich in the world to reach Sustainable Building. This means roof and homelessness can be solved by rather low efforts and extremely lowinvestments for large needs on the one hand and the Rich could bring down their exaggerated energy and resource consumption on the other hand. 10 The one approach to reach this ideal, but for the balance in the world necessary situation, is, to build mainly with easy and continuously renewable materials much easier renewable than timber or wood, namely materials like grass, elephant grass, straw, reed, bamboo, Jeruzalem artichoke, maize, sunflowers .... The other approach is to use highly advanced materials and products, but only in the smallest, thinnest and lightest quantities and dimensions. Both these approaches can be worthwhile in all parts of the world. A start, even based on some marginal traditions with similar developments is already made. Building with . strawbales and reed roofing, bamboo and various other plantmaterials is wellknown as well as the use of fabrics, foils and wires for building purposes. The Straw Panel System (SPS) The biggest volume of available matter certainly including the most renewable material is the biomass on the surface of the pla in all continents, reproduced each year. From the above mentioned kinds of plants we are able to produce ma
