【正文】 to realise Sustainable Building in practice. In order to help the process of being aware as well as to apply the insights, two conditions – translated into rules of thumb – have to be fulfilled, namely ‘collaboration’ (. by the Method Holistic Participation– MHP) and the proper choice of building materials (by the Matrix for the choice of Material with minimizing risks for health and damage of the environment), representative for similar necessary actions. There are innovative proposals for Gaia Building Systems, but there is still a change in paradigms and habits needed in order to be able to build really sustainable.

Finally, everything, including the energy flow, ends up in the environment. But on the way, unfortunately, the handling mostly was executed without consideration for the availability of resources on long term, in other words exploitation, without consideration for pollution either of the environment and/or concerned and mitted persons and people. Already nowadays we got the proof, that many of the negative effects will last for a long and very long time. We recognize the whole life cycle as an extraordinary plot on the environment, and, paradoxical 4 enough, very often also as a plot against our own health and safety, certainly on a long term. If we would like to reach a Sustainable Development we have to reduce the consumption generally, we have to reduce the consumption of energy, directly and indirectly used, and we have to minimize or even to exclude the pollution. Concerning deterioration of the landscape and exploitation of resources we earnestly have to search for renewable sources, whichs applications lead only to a short lasting deterioration. EFFECTS The effects of building activities are manifold. In the former chapter we spent attention to the life cycle of a (building) material, mainly in terms of phases or periods, shortly in terms of time. Concerning space it is possible to distinguish a number of dimensions or scales, in order to be able to specify effects in this field(s). There is a practical order with the dimension of: Local Regional Fluvial Continental Mondial, and even Cosmic with reference to the fact, that the production and traffic processes, shipping and space exploration. Thus six dimensions. The areas which (can) undergo an impact and influence can be distinguished into: Earth (the ground, including the Mineral Kingdom) Water (all kinds of rivers, lakes, seas, ? ..) Air (the atmosphere) Energy (mainly the energy sources), furthermore the Plants Kingdom the Animal Kingdom Humans (to be understood also as a part of nature) with their (valuable) Cultural Artefacts and possibly miscellaneous, Nine areas in total. These areas, just explained, can be found on local, regional, fluvial, continental and mondial scale. This means, that an impact or influence, caused by a production process or the use of building can affect or effect these areas locally, fluvially, continentally, mondially or even cosmically. Thus six dimension. Beside this, it is necessary to realise, that the effects can e from the various activities, connected to the whole life cycle of a building material or product and the concerned processes. We distinguished nine of those activities. Three before, three during and three after the use of a building, nine together. The possible effects are innumerable. Sick Building Syndrome on the one hand, pollution, deterioration and exploitation on the other hand, are only rather summarizing effects. 5 The reports on base of measurements and enquiries concerning building related illnesses, human and ecotoxicological problems, amongst others in the food chains of animals and men, changes of landscapes and ending resources, beside the elianated and decreasing cultural values, goes already in the tens, h
