Impacts of a non sustainable construction

• Depletion of natural resources (water, materials,
  fossil energies,)

• Impact on health (epidemics, asthma, allergies,
• intoxication, cancers)

• Impact on climate change (overuse of fossil
  energies in
• transport, construction activity and needs of
  energy)

• Environmental degradation (air and water
  pollution,
• destruction of natural habitat and
  biodiversity,)

Moral responsibility of architects

• Buildings act as our third skin

• Architects and engineers are responsible for the
  impact of a
• building

• We spend most of our time in buildings

• They can contribute to a better life

• The sustainability of a buildings depends
  primarily on the design
• and construction techniques used

• They must find solutions to environmental,
  social, and
• economical issues

Sustainable development a holistic solution
Sustainable development is development that
meets the needs of the present without
compromising the ability of future generations to
meet their own needs (Our Common Future, the
UN Brundtland Report, 1987)
