What is sustainability
 It is the capacity to endure.
 The word is derived from the Latin sustinere
  (tenere, to hold; sus, up). The word sustain: to
  “maintain", "support", or "endure”
 "Meeting the needs of the present without
  comprising the ability of future generations to
  meet their own needs."
  ___Bruntland Commission of United Nations
 "Sustainability is improving the quality of
  human life while living within the carrying
  capacity of supporting eco-systems."
  ___IUCN/UNEP/WWF (1991)-Caring for the Earth
 Sustainability has become a wide-ranging term that
  can be applied to almost every facet of life on Earth,
  from a local to a global scale and over various time
  periods.
 As the earth’s human population has increased,
  natural ecosystems have declined and changes in
  the balance of natural cycles has had a negative
  impact on both humans and other living systems.
   There is now abundant scientific evidence that
    humanity is living unsustainably.
       Limited energy resources
       Green house effect
       Ozone depletion
 Returning human use of natural resources to
  within sustainable limits will require a major
  collective effort.
 Ways of living more sustainably can be in many
  forms;
       reorganising living conditions (e.g., ecovillages, eco-
      municipalities and sustainable cities)
     reappraising economic sectors (permaculture, green
      building, sustainable agriculture)
     re appraising work practices (sustainable architecture)
     using science to develop new technologies (green
      technologies, renewable energy)
       adjustments in individual lifestyles
Sustainable design
Sustainability in architecture
   ‘‘Sustainable building design involves the
    considered and logical evaluation of a
    building’s life cycle impact in terms of
    environmental pollution and resource depletion.
    By the application of rational and systematic
    design policies and strategies, it aims to
    reduce that impact to levels that are within the
    capacity of the environmental,social and
    economic support systems on which the
    building is dependent to manage without
    adverse affect on other life forms or their
    support systems.’’
 During a building’s existence, it affects the
  local and global environments via a series of
  interconnected human activities and natural
  processes.
 At the early stage,
        site development and construction influence
        indigenous ecological characteristics.
       the influx of construction equipment and personnel
        onto a building site and process of construction itself
        disrupt the local ecology.
       the procurement and manufacturing of materials
        impact the global environment.
   Once built,
       building operation inflicts long-lasting impact on the
        environment. For instance;
          the energy and water used by its inhabitants produce
          toxic gases and sewage;
         the process of extracting, refining, and transporting all

          the resources used in building operation and
          maintenance also have numerous effects on the
 As a society’s economic status improves, its
  demand for architectural resources — land,
  buildings or building products, energy, and
  other resources — will increase. This in turn
  increases the combined impact of architecture
  on the global ecosystem, which is made up of
  inorganic elements, living organisms, and
  humans.
 The goal of sustainable design is to find
  architectural solutions that guarantee the well-
  being and coexistence of these three
  constituent groups.
Sustainable design principles
   Sustainable design principles include but are
    not limited to:
       Increase in energy and water efficiency and
        conservation;
       Increase in use of renewable energy resources;
       Reduction of elimination of toxic and hazardous
        substances in facilities, processes and their
        surrounding environment;
       Improvement of indoor air quality and interior and
        exterior environments leading to increased human
        productivity and performance and better human
        health;
       Use of resources and materials efficiently;
       Selection of materials and products that would
        minimize safety hazards and cumulative
        environmental impacts;
   Salvage and recycling of construction waste and
    building materials during construction and during
    demolition;
   Prevention of the generation of harmful materials and
    emmissions during construction, operation and
    decommissioning/demolition;
   Implementation maintenance and operational
    practices that reduce or eliminate harmful effects on
    people and the natural environment;
   Reuse of existing infrastructure, locate facilities near
    public transportation;
   Consider redevelopment of contaminated properties.
