1、- 1 - 外文 文献 ： THE LIFE CYCLE OF BUILDING ABSTRACT Sustainable Building is a global issue. The life cycle of building influences the life cycles of the whole planet dramatically. Some of the methods concerning Environmentally-Sound and Healthy Building, developed and used in The Netherlands will be p
2、resented and discussed in the perspective of world wide effects. Awareness about and development of those methods and approaches are actually yet not at their end. The scientific and technical complexity of the theme and the fact that the objectives are items of commercial and political interests ma
3、ke Sustainable Building a delicate problem. However, after having seen how complicated it is to contribute to a Sustainable Development substantially, we will conclude with some Rules of Thumb and Innovative proposals, in order to stimulate more significant contributions in the future. INTRODUCTION
4、Knowledge on Sustainable Building was an item of highest importance already in the begin of human culture and civilisation. Looking back, in history, we find that Sustainable Building was a question of survival. Protection against weather circumstances, dangerous animals and hostile fellow men belon

In order to fulfil these demands it was necessary to find an equilibrium between the environmentally or ecologically based possibilities of resources and their limits and the needs and wishes for a durable home. Beside this it was determining for a built re
6、sult, which and how much capacities for the realisation were available. Energy for building purposes was mainly given by human power, and for a part by the use of animals and more indirectly sometimes by fire or wind. But fire was dependent from fuel. Similarly there was only building material at ha
7、nd, which could be found near to the site, because it was generally too costly, nearly impossible, to transport main materials from a source far away. When humankind started to exploit or produce (hard) energy on a large scale - at least a part, in - 2 - the so called West - by steam, electricity fr
8、om fuels like coal, mineral oil, gas, hydropower and finally nuclear power, the scene of building changed dramatically, certainly in the rich countries, which used and still use to exploit others. In spite of pollution, deterioration and exploitation - these phenomena even mostly fully ignored - the
9、 socalled industrial revolution started. Independent from a vital need, mass production firstly of all kinds of goods and later of more and more building products started. With the economical interest and power it was possible to create markets and to sell the mass products, even to far away located
10、 consumers, while the relative easy new transportation lines of train and ship and later of truck and airplane, helped and help still to bring or catch raw materials from far away. Regional building disappeared in big parts of the world and with an International Architecture it was even postulated,
11、that everything could be the same everywhere. In the last decades we slowly recognized the terrible effects of this way to build in our environment as well as on ourselves. The mondial disaster might be, for approximately a third, the effect of the building activities, while the Sick Building Syndro
12、me is fully created by the recent and nowadays way to build and to dwell. At the same time we should be aware that the rich appearing, technological advanced countries, which are approximately 20% of the whole humankind, can effort this style only by exploiting the + 80% of humankind, which are call
13、ed the Poor, under whom a population of about 20% hardly can survive. It seems extraordinary difficult to increase the awareness of the first World concerning these relations within our mondial society. But even more difficult it is to transform our behaviour towards more balanced circumstances in t
14、he world. This contribution aims to help, modestly, to support a strategy together with the necessary know how towards Sustainable Building as an essential part of Sustainable Development. The entire building process from cradle to grave or even from cradle to cradle in its relation to the environme
15、nt in terms of energy use and emission between digging (in put) out of the environment and bringing back (out put) into the environment. On the way of this life cycle we face exploitation, pollution and deterioration of the environment. Partial reuse is always good, but it is only a very low compens
16、ation for the damages, which the whole process causes. - 3 - LIFE CYCLE Looking more carefully (than usual) to the Life Cycle of materials and products (and similarly also to the flow of energy), applied for all kinds of purposes, including building, it is useful to distinguish in the relationship o
17、f the changes a material (or an energy) undergoes with space and time. Doing so, we systematically can focus on the various impacts which the chain of causes and effects of the life cycle of a material has, in different scales and on short, middle, and long term. Before and after the final applicati
18、on and destination of a material, as a component in a building, while it is used - the actual goal of a building material - we can distinguish a number of characteristic activities. There are roughly the following activities: Before the phase of using a material it firstly has to be digged or harves
19、ted out of the environment. Secondly the building material has to be made out or produced from the raw material. Thirdly and mostly there is a certain assemblage needed in order to get a useful building component. In between these main activities, transport and storage is needed very often. All of t
20、hese acts need energy and there is hardly one of them which does not create emissions. To make a building useful, it needs the finishing touch together with the integration of all equipment and furniture, which will go on during the use of the building together with cleaning, care taking and exploit
21、ing the building. Heating and/or cooling and lighting are conditional in this period as well. Again, all of these handlings need energy and there is hardly one of them, which does not pollute the environment. After and partially already during the phase of use, it will appear, that changes, or, at l
22、east strong, maintenance is needed. Partial demolition will be one of the consequences, than partial or full renewal or refurbishment can take place. Although there is a resource - saving possibility of reuse of various gradations with more or less manipulations, needed for a final proper reuse - ag
23、ain we can sing the refrain of the need of energy and emission. 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 exploitatio
24、n, without consideration for pollution either of the environment and/or concerned and committed 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
