A Definition of Sustainability

• Sustainability requires us to live within the
  limits of the earths capacity to provide the
  materials for our activities and to absorb the
  waste and pollution that our activities generate.

What is Sustainable Design?

• Appropriate use of land
• Use water and energy efficiently
• Enhance human health
• Strengthen local economies
• Conserve plants and animals
• Protect agricultural, cultural and archeological
  resources
• Economical to build and maintain
• Nice to live in
• Beautiful

Building Shape Guidelines

• Cold Climates
• Maximize winter heat gain
• Make buildings compact in cold climates to reduce
  heat loss
• Elongate along the east/west axis to maximize
  solar gain

Building Shape Guidelines

• Temperate Climates
• Maximize winter heat gain and minimize summer
  overheating
• Rectangular building aligned with the east/west
  axis
• Overhang design very important

19
Building Shape Guidelines

• Hot and Humid Climates
• Minimize heat gain through windows
• Ventilation and shading maximized
• Building form should be elongated on an axis
  perpendicular to the summer wind patterns
• The plan should be open

20
Building Shape Guidelines

• Hot and Dry Climates
• Minimize solar gain through shading, especially
  on the western side
• Promote air movement through cross ventilation
• U-Shape will create a cool inner courtyard
