DEFINITION OF SUSTAINABILITY * The word sustainability is derived from the Latin sustinere (tenere, to hold; sus, up). * “maintain” “support” “endure” * Theconcept of sustainabilitycenters on a balance of society, economyandenvironmentforcurrentandfuturehealth.
DEFINITION OF SUSTAINABLE DEVELOPMENT * Development thatmeetstheneeds of thepresentwithoutcompromisingtheability of futuregenerationstomeettheirownneeds. * Dynamicprocesswhichenablespeopletorealisetheirpotentialandimprovetheirquality of life in wayswhichsimultaneouslyprotectandenhancetheearth's life supportsystems.
History of Sustainability * Firstuse on March 1972, in report on the "LimitstoGrowth", writtenby a group of scientistsledby Dennis and Donella Meadows of the MIT. Describingthedesirable "state of global equilibrium", theauthorsusedtheword "sustainable"

Sustainable CONSTRUCTION • A holistic process aiming to restore and maintain harmony between the natural and built environments, and create settlements that affirm human dignity and encourage economic equity. • Sustainableconstructionaims at reducingtheenvironmentalimpact of a buildingoveritsentirelifetime, whileoptimizingitseconomicviabilityandthecomfortandsafety of itsoccupants.
What Makes Construction Sustainable? • Construction is said to be sustainable when it meets environmental challenges, responds to social and cultural demands and delivers economic improvement.
What Makes Construction Sustainable? • 1. Reduce resource consumption (reduce) 2. Reuse resources (reuse) 3. Use recyclable resources (recycle) 4. Protect nature (nature) 5. Eliminate toxics (toxics) 6. Apply life-cycle (costing economics) 7. Focus on quality (quality)
What Makes Construction Sustainable? Sustainable construction projects consider: • Energy efficiency and reducing the energy used in daily operation. • Using sustainable construction supplies such as recycled materials and renewable resources. • Environmentally sustainable features like rooftop gardens, water reduction measures, and the use of nontoxic building materials. • Using local materials that are both easier and cheaper to bring in • Constructionof public uses spaces like walking trails and shaded park that help the structure to better fit with the natural environment, and add benefits to the local community.
What Makes Construction Sustainable? * Routinely designed and maintained to optimize the entire life span, * Sustainability considerations and requirements should take in building legislationand standards, * Environmental aspects should be considered in the project and should include short-term as well as long-term aspects, * Policies and incentives provided by the government to support sustainable building and construction practices, * Investors, insurance companies, property developers and buyer of buildings are aware of sustainability considerations and should take an active role to encourage sustainable building and construction practice.
