3 WHY SUSTAINABLE CONSTRUCTION Unconscious Consuming Ozone Layer Depletion Decreasing Bioderversity Usage of Fossil-based Energy Resources 3/53

4 DEFINITION OF SUSTAINABILITY * “maintain” “support” “endure” * The concept of sustainability centers on a balance of society, economy and environment for current and future health. * The word sustainability is derived from the Latin sustinere (tenere, to hold; sus, up). 4/53

5 * Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. DEFINITION OF SUSTAINABLE DEVELOPMENT * Dynamic process which enables people to realise their potential and improve their quality of life in ways which simultaneously protect and enhance the earth's life support systems. 5/53

6 HISTORY OF SUSTAINABILITY * First use on March 1972, in report on the "Limits to Growth", written by a group of scientists led by Dennis and Donella Meadows of the MIT. Describing the desirable "state of global equilibrium", the authors used the word "sustainable" 6/53

9 DIMENSIONS OF SUSTAINABLE DEVELOPMENT 9/53

10 PRINCIPLES OF SUSTAINABLE DEVELOPMENT Maintain and, if possible, enhance, its residents’ quality of life. Enhance local economic vitality. Promote social and intergenerational equity. Maintain and, if possible, enhance, the quality of the environment. Incorporate disaster resilience and mitigation into its decisions and actions. Use a consensus-building, participatory process when making decisions. 10/53

11 EFFECT OF CONSTRUCTION INDUSTRY ON SUSTAINABLE DEVELOPMENT  Deforestation  Destruction of flora and fauna  Pollution 11/53

12 EFFECT OF CONSTRUCTION INDUSTRY ON SUSTAINABLE DEVELOPMENT 12/53

13 SUSTAINABLE ARCHITECTURE 13/53

14 SUSTAINABLE ARCHITECTURE 14/53

15 SUSTAINABLE ARCHITECTURE 15/53

16 SUSTAINABLE ARCHITECTURE 16/53

17 ELEMENTS OF SUSTAINABLE ARCHITECTURE 1. Sustainable energy use Heating, ventilation and cooling system efficiency Solar panels Wind turbines Solar water heating Heat pumps 17/53

18 2. Sustainable building materials Recycled materials Lower volatile organic compounds ELEMENTS OF SUSTAINABLE ARCHITECTURE 18/53

21 5. Sustainable building consulting Green Building´s analysis and computer simulation ELEMENTS OF SUSTAINABLE ARCHITECTURE 21/53

22 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. Sustainable construction aims at reducing the environmental impact of a building over its entire lifetime, while optimizing its economic viability and the comfort and safety of its occupants. SUSTAINABLE CONSTRUCTION 22/53

23 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? 23/53

24 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? 24/53

25 Sustainable construction projects consider: WHAT MAKES CONSTRUCTION SUSTAINABLE?  Construction of 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.  Using local materials that are both easier and cheaper to bring in  Environmentally sustainable features like rooftop gardens, water reduction measures, and the use of nontoxic building materials.  Using sustainable construction supplies such as recycled materials and renewable resources.  Energy efficiency and reducing the energy used in daily operation. 25/53

26 * Routinely designed and maintained to optimize the entire life span, * Sustainability considerations and requirements should take in building legislation and 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. WHAT MAKES CONSTRUCTION SUSTAINABLE? 26/53
