Green Design Overview
The exponential increase in population and contemporaneous increase in standard of living for many, will mean that the demand for essential goods & services (transportation, cars, planes, but also housing, materials, water, food) will increase by at least a factor 2 in the next few decades. If the need to support an additional 3 billion people and effect of increase per capita consumption is added it is clear that the linear material flow (from excavation to disposal) present in the existing industrial systems is not sustainable. Many scientists speculate that if 9 billion people have a western life style in 2050 we would need 6 Earth’s to provide the necessary resources to sustain a population. A point has been reached when search for sustainable solutions for the resource feedback loops has become unavoidable.
At the times of global climate crises and when natural materials supplies are gradually depleting and becoming increasingly expensive the durability of buildings and products is becoming a major issue. Issues as adaptability, reconfigurability, reuse and recycling will be critical to the building and product value in the future.
Some have suggested that industrial systems could use the metaphor and behavior of biological systems as guidance for sustainable design.
In an ideal case one can adopt as a goal that every molecule that enters a specific manufacturing process should leave as part of a saleable products; that the materials and components in every product should be used to create other useful products at the end of product life; (Greadel and Allenby), and that the main structure of every building can accommodate different use patterns during its total life.
The aim of green design is to close the loop of industrial processes and bring material and energy back into a industrial cycle while eliminating the concept of waste. Unlike car and product design where concept of industrial ecology (closed life cycle of products) has been investigated and applied in the past, this approach is revolutionary when it comes to the building design.
Considering the fact that the modern economic systems relay on ever increasing consumption of products, that product and building use cycle is becoming ever shorter and that most end of life scenarios for buildings and products is waste disposal, there is huge task put in front of designers and production industry. The main question put in front of designers in 21st century is how to design and produce zero waste and carbon neutral products and buildings? This question can be successfully answered only by joint efforts of designers and industry and a more analytical design approach that is integrating the requirements of all life cycle phases of an artifact form the beginning of a design process.
