I think in a certain sense it already is.

Unfortunately, keywords like "sustainable" or "green" are used (on purpose or not) misleadingly, which sometimes makes it hard to use a more serious approach and defend its costs in front of clients.

It is one of the greatest challenges to find and make public the "hard evidence" and "scientific reasons" for the truly green design decisions.

Camile:

In fact, the drivers of a cultural revolution are three: social sustainability, environmental sustainability and economic sustainability.

I believe that the evolution of any city is occurs as a function of the complex system of interactions established between the urban fabric and the economic, social and cultural fabric that fills and the models. The increasing complexity of these interactions, accelerated from the massive introduction of global transformations is that triggered the new metabolism of the contemporary city.

Today, a city to live needs to adopt a new philosophy of planning and management to ensure its sustainable development. Creating urban conditions, social, economic, cultural and environmental quality to live with in the cities of tomorrow, is thus one of the greatest challenges that we face.

The alternative is a model of sustainable development. A creative process and seeks a balance between all areas and only way to the development of living standards and conditions of nature, and for social justice, based on equity and economic and social sustainability. Just from a management process of this kind, can take decisions that meet the interests of today's citizens, without compromising those of future generations.

I think that sustainability concept can help to drive architecture and urban planning to a new paradigm. Moreover, this new paradigm is actually needed to reach sustainable development. Respect to density, sprawl and growth, in my opinion it is difficult to decide if cities new metabolism has to be faster than today. Some authors belive that a faster city, with increased density and intensified soil use can be more sustainable and efficient. You can see for example the works of Bettencourt and West, published in Nature and other Journals... But I'm not sure that this vision is right.
