Sustainable development is defined as "meeting the needs of the present without compromising the ability of future generations to meet their own needs." However, sustainable development is the needs of the new generation. We all need the development to improve our life. Sustainability is included economic growth, environmental stewardship, social progress, social economic, social environmental and also eco-efficiecy.
Sustainable development is related to sustainable construction. Besides, sustainable design recognises the interdependence of the built and natural environment.It seeks to harness natural energy flows and biological processes, eliminate reliance on fossial fuels and toxic materials and improve resources and efficiency.
Therefore, there some new designs appeared which are design for demolishing and design for recycling.
Recycling------->reuse-------->reduce is also called 3R where is the one of the steps to reduce our disposal and rubbish. This programme would improve the bad conditions of our environment.
CHALLENGES AHEAD IN THE BIULT ENVIRONMENTMore people means more shops, more houses, work places, roads and etc. More demand of the products and services the greater the demand for lands.
more people = more cities = more impact
So, new ideas, new paradigms, new approuches to building and construction are urgently needed.
The energy consumption of building and construction is 10.2% of operation of building, 9.9%
of operation of business facilities, 1.3% of construction work, 5% of transportation related to construction, 10.9% of produ ction of materials for construction and 62.7% of other industries.
BUILDNG LIFE CYCLEpredesign ---- design ---- construction ---- accupancyTHE REAL CHALLENGESGlobal warming is an example of what happen where we do not develop sustainably. Ignoring the issues of sustainable development has many possible consequences such as rising see levels, extreme droughts, erision abd loss of forest, increase in slum population species extintions and collaping fisheries. There is also increasing evidence that issues such as water scarity play a role in internal violence and regional conflict.
Adaptable building also means that a particular building system s capable of adapting to a particular situation or use ; such as regional and climatic variances that include social , culture and technical difference.
BEESTARI is stand for building environment efficiency as sustainable tool for asessment and rating limitiative.
Green built environment is one way to make a difference.
