Abstract
The key factor in sustainable design is understanding the issue of sustainability. It is included in activities
aiming at bringing back the proper level between the need of the goods of the civilization and
between the ability of the Earth to provide the conditions to produce the goods and utilize the waste without
destroying the Earth’s ecosystem.
The natural environment is being very strongly affected by the construction which uses big part of the
Earth’s natural resources at the same time causing natural degradation. That is why currently in architectural
design as well as in the whole process of realizing the investment the key factors are: Reduce,
Reuse, Recycle, Renewable and Rethink. They are supposed to be the tips to design a building which is
understood not only as a form and function but also in the aspects of energy, water, waste, the green and
communication.
