Sustainable Design

Sustainable designs and green designs are used interchangeably. In aspects of building green the terms are complementary to each other. Confusion however exists in the exact meaning of the term sustainable design. The closest analogy in understanding what a sustainable design implies is to view the design as a self driven bio sphere.

Sustainable designs do not tax the environment, are able to recycle most of the products used and help better the living conditions. This involves holistic planning in the use of natural sunlight and wind. The most optimum use of solar energy to reduce electricity consumption and wind flow patterns to reduce the CFC producing air conditioners are some of the aspects of sustainable design. A sustainable design looks at conserving water by harvesting rain water. Recycling of water used for bathing for the kitchen garden is yet another aspect. Conversion of organic wastes generated by humans into manure is a sustainable design feature.

A range of initiatives such as sharing a common swimming pool, common rainwater harvesting plant, solar panels all add up to the conservation aspects in a sustainable design. Why, even car pooling by residents of a green community is part of sustainable design movement. Locally used material which can be replenished are encouraged in a sustainable design. So if repairs are required of the building, material need not be hauled over long distances but be utilized from around the environment. Such initiatives need government aid to succeed. To do this several governments have set sustainable design standards. The LEED standard evolved by USA is the most common one being used all over the world. The contribution of the scientific community in providing life cycle calculations for sustainable designs have been an important factor.

Scientists have helped arrive at life cycle energy analysis and introduction of modern technology to the overall ambit of life cycle calculations for sustainable designs. These include inventing better solar panels, better interface with indigenous building practices with modern equipment and optimum utilization of powerful computing available to arrive at simulations for a truly sustainable design. The Greek concept of 'Gaea', which epitomizes a perfect harmony between Earth and all beings living and non-living, is a final ideal that proponents of sustainable design strive to achieve.
