the design process

ecologically sustainable development:
    accommodating the needs of the present without compromising
    the ability of future generations to meet their own needs
    (Brundtland Report, World Commission on Environment and Development 1987)

appropriate technology:
    making and using technology that meets human
    needs while taking into account long and short
    term consequences for society and the environment

 sustainable design process:
      1. understand the needs of the users of the building
      2. look at the capacity of the site and the environment in
                 supporting those needs
      3. make design decisions and use appropriate technologies to fulfil
                 the above
