Green buildings from the home to the city

  1. 1. Green Buildings – from the home to the city Urban Permaculture ideas S.Vishwanath www.biome-solutions.com www.rainwaterclub.org You-tube, Twitter, Slide-share, Face-book : zenrainman 1
  2. 2. What is permaculture ? • One definition (there are many ) • CREATING SUSTAINABLE HUMAN HABITATS BY FOLLOWING NATURE'S PATTERNS • Comes from permanent agriculture and then permanent culture 2
  3. 3. Who is it for ? • It is for everyone wishing to live sustainable and tread more lightly on the Earth. 3

  5. 5. Permaculture principles • Work with nature not against • See solutions not problems • Seek diversity not monoculture • Every element should serve many functions • Yield is limited only by imagination • Work in cycles and zones – Source Permaculture a beginners guide –G.Burnett 5
  6. 6. Earth • The removal of good top soil for brick making destroys the soil in the peri-urban areas of cities • The use of sand for construction destroys rivers and water sources as well as land due to a process called filtered sand 6
  7. 7. Earth • Every site has earth • In the design of the building incorporate earth • Remove the top soil and keep it • Design a basement to excavate earth • Use this to make earth blocks /cob/rammed earth for construction • The material for walls can come from the site • Sand requirement can be reduced by 50% – 60 % 7
  8. 8. A basement provides earth for the house 8
